With the security umbrella provided by the US, South Korea has been able to take a step-by-step approach. Same with KF-21. An evolutionary itinerations. Its flight control system uses the latest technology (sensor-based NDI), which makes itinerations and weapon-integration much cheaper in terms of money and time. KF-21 seems to be the only kind which uses this technology; F-35 uses NDI but model-based NDI. For South Korea, KF-21 is a must for missiles and UAV Man-Unmanned Teaming (MUMT). (1) You are not allowed to integrate Korean missiles with US-made fighters; and the US is reluctant to sell too disruptive missiles to SK; and the US missiles are too expensive. South Korea has the state-of-art missile technology. So they think “if we have indigenous fighters, we can develop various kinds of air-launched missiles and integrate them.” (2) You are not allowed to import foreign made UAVs with big payloads because of the Missile Technology Control Regime(MTCR). As a result, you cannot do MUMT operations with imported F-35s, F-15s or F-16s, because the US fighters interoperate only with the US-made UAVs. So South Koreans think “if we have indigenous…” And you cannot import avionics, engines, or missiles for high-end UAVs with big payloads (because of the MTCR) South Koreans are developing turbo engines for high-end UAVs. 1,400 hp turbo-shaft 5,500 lbf. turbo-fan; 10,000 lbf. turbo-fan. Sooner or later South Korea is going to add 16,000 lbf. turbo-fan(with 24,000 lbf after-burner thrust) to its target list. These high-end UAVs can share the avionics and missiles developed for KF-21. So the issue of 'stealth-or-not?’ is not that critical. A good 4.x generation fighter KF-21 with defensive EW capabilities or with some level of offensive EW capabilities, which is cheaper than (or equal to the cost of) F-16V Shield or IVEWS… And wlth the same level of hourly operational cost of F-16s… These requirements are more impending or important for South Koreans, as this video says. If they are met, KF-21 will be a bargain. For KF-21 is planned to be much superior to F-16 in almost every aspect.
The U.S. technology base has collapsed in terms of cheap mass manufacture and revolutionary paradigm shifting innovation. No lasers. No hypersonics. No UCAV. This is what happens when you trade cultural homogeny and advancement for third world welfare state immigration policies. Your population becomes dumb and demoralized because they are not allowed to acknowledge differentials in capability and moral capacity as whom they want to live with. The U.S. financial/economic system will degrade based on their failure to invest in (automan, robotics, genomics) technology, their poor immigration choices and their endless appetite for war. As they fail, through their overeased and over valued dollar and it's poor balance of trade effects on the consumer power of their population PPP, they will fade from the world, bringing home their legions, like Rome, because they cannot sustain same. With this in mind, the Number One and Two defense technology disruptors Korea needs to invest in are cheap, small, nuclear weapons and ABMD which is both dense and deep in terms of effector spread and stockpiling. Especially where this means laser based systems, in the 1MW range, they will technically spell the doom of manned aviation. The world sees Ukraine and Israel and understands that the day of the manned jet is passed compared to ever faster and more difficult to shoot down turbine-drones like the Shahed 238. Coupled to highly capable TBM/SRBM weapons which are both mobile and easily hidden. The difference in reaction time, persistence and bus cost are just too enormous to be ignored. The KF-21 might have made sense, 20 years ago. Today, without internal weapons bays and dedicated emphasis upon full signature management, it is a sportscar version of the F/A-50 with better looks but less justifiable costs. This is a shame because the overal kinematic performance of the KF-21 is probably very good. A 26,000lb EEW, 14,000lbs of internal fuel, and 4,000lb weapons/consumables/aircrew load translates to exactly 1:1 T/Wr at takeoff and this, coupled to the type's refined Raptor shaping probably makes it an excellent maneuvering ACM and sprint capable interceptor. But if it's not survivable in a late 20-series SAM environment and it's ability to carry heavy standoff munitions lke the Chun-Ryong are limited by it's small wing area, then it is almost certain to be an economic failure. The one thing you can say is that the Daewoo/KAI KF-16Cs are themselves starting to get really long in the tooth. And so having a high end replacement for them as the F/A-50 is the actual replacement for the F-5E, is probably wise. The issue remains however that the primary enemy Korea faces has serious nuclear capabilities and without the U.S. nuclear umbrella (as we pull back from Asia), the survivability of ANY platform which is dependent on 6-10,000ft of runway as target localized signature driver is...very low. The Koreans are really smart, I am sure they have a plan in place to accommodate all these factors. It's just a matter of whether they can execute before the coming U.S. collapse. One immediate element of security posture change they could work on would be alliance with Japan which has both the nuclear system knowledge and the 500nm standoff to allow pre-conflict withrdrawal of the ROKAF to the likes of Chitose where, in combination with serious tanker purchases of something like the MRT330, the Seoul government could maintain a viable deterrent capability until such time as they developed missile based alternatives. Again, the Koreans are really competent engineers and warfighters, it's just a matter of whether they can overcome historical resentments and mistrust to develop regional defense committed partnerships as the United States Aegis fades and not just the DPRK but the Russia and Chinese threats begin to rise.
2:50 In fact, The Korean government faced no financial difficulties in pursuing the KF-X program. Instead, the main challenge was securing future sales opportunities. To address this, Korea sought to attract partner nations willing to invest in exchange for purchasing commitments, offering incentives such as technology transfer, a prototype, and licensed production rights. Indonesia joined the program under these terms but failed to meet its financial obligations and allegedly misused the technology provided during the collaboration.
South Korea has F-35s, so they don't need another 5th gen fighter right away. They will develop KF-21 in phases. Block 1 and block 2 are 4.5 gen fighters. Block 3 will be 5th fighter.
The Rafale and Typhoon is 4.5 and the video says it designed to have a better RCS than that, but below 5th generation. Its between 4.5 to 5 Gen Cheers !
Photonic radars will completely nullify stealth. Yes they will be ground bases radars soon and it will take them a while to also get into aircraft but stealth's days are numbered anyway.
I think that SK has a very good plan. Use KF-21 to learn and test all the systems for developing the full stealth variant. Iron out all the kinks so to say. With NK posturing all the time SK needs a sustainable fleet of aircraft. The high low mix between the two variants makes a lot of sense. Incremental innovation.
Considering the speed of development at KAI, this plane will eventually evolve into a stealth aircraft. ROKAF already has f-35's. There wasn't a direct need for stealth considering their direct adversary. It'll happen. From the footage I've seen, looks highly maneuverable and will undoubtedly be much cheaper to maintain then it's western competitors.
@@fqeagles21 not really but sure. Lots of aircraft have enlarged variants and aren't considered new planes. If you want to know how they will do it without they can make stealth pylons and put covers over the semi recessed weapon bays
@@fqeagles21 they already designed it into the prelim design. I believe it's just a simple airframe modification when needed. There's some prototype photo of the airframe.
I think it is a wise move. There are many countries that don't need highly-capable but expensive 5th-gen fighter jet like F-35. To them, the F-16 or French Rafale are more than enough in the future. Cheap to buy, operate, maintain and capable enough. But alas, they are developed 30-40 years ago and are practically in the last period of their useful platform life. We can not expect much upgrade and support in the long run. KF-21 will fit in the market position of the old and aging F-16's perfectly in 21-st century sky. Even major air force with F-35 will need less expensive workhorse fighter jet like KF-21 to mitigate rising defense budget woe. Korean air force is one of such AF.
@@Domo6768the more that are produced and the more buyers the cheaper it will be, also since anyone buying f16s or rafals right now will 100% need to initiate an upgrade program for them in the next 10-15 years they will get just as expensive where as the kf-21 won't need any extensive upgrades or refits for 20+ years
@@Domo6768 at least cheaper than F35... there's no need to reapply the RAM every few often since it's designed to be that way with only the design being the RAM. What most countries needs is a peacetime interceptor with a chance of being missile truck should the war comes knocking...
The cost of upgrading the F-35 is more expensive than the selling price of the KF-21. For most countries, upgrading the F-35 would be a prohibitive expense.
But the F-35 in its pre TR3 content in current war games the win ratio against modern US and european 4.5 gen fighters is a whopping 7 to 1. F-35 is well worth the same cost as a super hornet, cheaper than eurofighter, Rafale and F-15EX yet out performs these aircraft at a 7 to 1 ratio. The F-35 TR3/block 4 only pushes this fighter further as the world's current best multirole fighter, a generation in front of what's out there.
This makes a fair bit of sense. Cheaper and quicker to develop than the F-35 with stealth features that can be added at a later date. Whilst being initially stealthier than the F-16, Typhoon, Rafale, Gripen and JF-17.
I mean, it'll be a lot of work to add better internal space and it'll need major changes to the structure. It's more like a poor man's 22 with more multiple capability. Not that it's bad, it takes a place that sk really needed a ln upgrade in
1. Due to the impact of global inflation, the price of the F-16V exceeds $100 million based on the program cost. The F-16 production line, located in Greenville, South Carolina, has a low rate of production, which is difficult to produce 24 units a year. The price of F-15EX is also more than 120 million dollars. The price of weapons is also skyrocketing due to F-35-class electronic equipment and inflation. 2. The initial mass production cost of the KF-21 Block1 40 units is 80 million dollars per unit based on the program cost. KF-21 block2 is also scheduled to be mass-produced for 80 units at a similar price, and the mass production of 120 units has already been decided. 3. After the mass production of 120 KF-21s, 32 ROKAF's F-16PB (Block32) must be replaced, and then 131 KF-16U must be replaced with KF-21. 4. To sum up, the KF-21's scheduled ROKAF own demand alone is 270~300 units for the next 20 years. South Korea's own demand alone will exceed the break-even point, and the problem is how much is left to export. 5. And, it's also interesting whether the reinforced KF-21 to replace the F-15K can appear.
As long as they can meet the demand... that's what they said to the gripens when Ukraine came knocking before they, SAAB, reply back “no can do”. Tho they did have quite a list for F/T-50, their previous.
@@PrograErrorExactly, KAI is partnering with Poland to mass produce FA-50 in Europe. It could expand program to make KF-21 in Europe too. Russia is a great motivator to buy it!
I appreciate your objective analysis and explanation. ROKAF believes that it needs a stealth aircraft with strong electronic warfare capabilities at a lower price and maintenance cost than the F35 and in the future, the KF21 aims to have a built-in electronic warfare capability stronger than the ALQ-200K utilizing MUM-T rather than RCS. ROKAF doesn't consider stealth capabilities very important and believes that the 60 F35s it already has are enough for stealth fighters.
Very good video, I know that the Peruvian air force plans to buy 24 fighter aircraft at the end of the year and the beginning of 2025 and everything suggests that they will be the KF21, as is known, Peru together with KAI already manufacture the KTP1 in Peru training aircraft and the visit of the president of Korea at the APEC summit held this month in Peru announcing that the industrial services of the Peruvian Air Force will manufacture parts for the KF21 and FA50 , they make it believe that the F.A.P will buy the KF21. We hope for that in Peru.
Trivia. the Radar is called the APY-016K it will be developed by Hanwah systems and will use GaN bassed T/R modules, it is water cooled with a peak power target of 30 kilowatts, (APG-77 for the F-22 has a peak power of 20 Kw) Also the KF-21 has a thrust to weight ratio much higher than the F-35, ranging from 0.78 at max take off weight all the way to 1.69 at empty weight. By comparison the F-35A ranges from 0.72 to 1.48
Being able to push the TWR that high with a light combat load is rather silly. They're also projected to be about the price of modern F-16s. It may actually be a direct replacement for a lot of countries if these can be mass-produced. If.
the figure I gave is for the entire range from max weight to empty, if we're going to be realistic and imagine the KF-21 entering the merge for whatever reason. dropping all it's drop tanks, with full internal fuel, 4 Meteor missiles, 2 Iris-T missiles, full gun ammo storage, Sniper ATP, the TWR will be around 1.25, thats F-22 levels of power to weight.
I've heard from a former Indonesian MinDef employee that KF21 IS actually a 5th gen, but they only declare it as 4,5 bcs 5th gen is already a political domain
With Korea's current technological capabilities, it is difficult to develop a 5th generation fighter at the level of the F-35 with both stealth and network warfare capabilities, but it is fully possible to develop a stealth fighter with stealth and electronic warfare capabilities. Fifth-generation fighters are a more technologically advanced concept than stealth fighters.
Many people in the comments only assume that North Korea is South Korea's enemy. However, China, even Japan, has a conflict factor with South Korea and has room for it to be viewed as a potential enemy. Although North Korea's air power is disastrous, it is not enough to say that South Korea's air power is sufficient, assuming that it has to deal with China and Japan's air power. This is why South Korea is trying to apply stealth technology to KF-21.
Given Turkey's strong pro-Russian tendencies, the breakdown in negotiations seems to be a positive outcome. Additionally, Turkey is the only dictatorship among NATO countries.
This is a smart approach to make a 4.5 gen fighter that becomes a 5th gen for the future variants. This is how Russian jets kept on improving over the years, especially their Su-27 and MiG-29 which has evolved to become Su-35 and MiG-35 today. It's cheaper than the American way to start from scratch that uses a lot of money for R&D and time. Once KF-21 implement internal weapons bay, stealth engine nozzle and radar absorbing material for future KF-21 variants, it will become a legit stealth fighter that compliments the F-35 while being cost effective.
Don't compare Russian 4.5 gen fighters to this, most of them are still at there core outdated tech this is more like a 4.75 gen fighter it's so close to being a 5th gen, and that's reflected in the fact they are making a variety that is a 5th gen fighter using it as a base
@@derekhenschel3191 I'm a pragmatic person and judge the plane based on facts, not emotion. As much as I like the KF-21, calling it a 4.75 fighter makes no sense when it's not even a multirole fighter yet. Currently, KF-21 is only capable of air-to-air combat, it can't possibly compete with Su-35 when it can carry all sorts of armaments and is a matured platform. Of course, this sentiment does not take into account for future variants that will surpass 4++ gen fighters. However, KAI is not there yet and will require some time to develop 5th gen technology
Yet stealth fighters are becoming less relevant day by day as gallium nitrate radars are becoming more widespread. And the more detection technologies will evolve, the less will stealth be relevant.
@@brunol-p_g8800 It's true that low frequency ground-based radar and gallium nitrite radar can detect stealth, but there are several limitations with radars. 1. It can't identify friend from foe especially in combat 2. Electronic warfare countermeasures can be used to disrupt the signals 3. Decoys and UAVs can be used to overwhelm and confuse the radar tracking system such as SEAD tactic 4. Ground based radars are vulnerable to enemy aircrafts and missiles 5. Ground based radars can't detect low flying aircrafts especially in mountainous areas and cities with tall skyscrapers. 6. Only a handful of countries can make high tech radars that are proven in combat. 7. Due to the earth's curvature, there is a blind spot for radars as it can only detect in a straight line 8. Radars have limited range and does not work well in bad weather especially thunderstorms.
I remember that the Red Allet 2, which was released about 20 years ago, had a Boramae fighter as a Korean unit. (It's a Black Eagle in English, but there's also an FA-50 Black Eagle team in Korea.) Did Westwood use future-reading superpowers to make the game?
Admittedly, I don’t know as much about this as I would like, but from what I have read isn’t the F 35 thrust Limited compared to what its engine can actually produce. If that is the case, then in the terms of thrust ratio, it’s basically equal to the South Korean fighter. Not to mention the South Korean fighter looks like it’s far more maneuverable than F 35.
The South Koreans had help from US Lockheed Martin (F-22, F-35) on the airframe design which is good and is upgradeable to a stealth fighter. US has barred tech transfer on AESA radar, engines and integration of AMRAAM & Sidewinder air to air missiles. KF-21 Block 1 air defence fighter uses Meteor BVR missiles and IRIS-T short range missiles.

If that is the case, then in the terms of thrust ratio, it’s basically equal to the South Korean fighter. Not to mention the South Korean fighter looks like it’s far more maneuverable than F 35. Additionally, there’s quite a bit of pressure from Lucky Martin to ensure the F 35 is the only fighter being exported across the world. A great shame in my opinion as it’s better to have more variety in the market.
"Pressure in certain aspects can sometimes be illusory. Specifically, pressure against countries with technological prowess and influence is bound to be futile. Such pressure against Korea, which is nearing the completion stage of its engine development, will not be applicable in this situation.
South korea main enemy is north korea and some cities or military bases or airfields are just few miles away with all north korea radar detection are on the south it means that stealth is even an option with tight and congested airspace, being 4.5 generation is the better choice along with having good payload capabilities, supercruise, agility and supermanuevrablity are suited better with advanced data link, jamming, electronic countermeasure.
The North Koreans have old radars as well 🙂 but they do have lots of Arty , Rocket launchers and Ballistic Missiles. Rocket Man Kim. Their Tanks also are museum pieces. However, defensively they are still sound in the current context. South Korea and its allies are not Empires .Invading NK for its land or strategic position. No point. Otherwise they would have Done Anything to take down North Korea. That usually reserved for the likes of Tojo (Imperial Japan) and Leopoldo Galtieri. Dictators that rule with an iron fist, the fatherland/motherland, Patriotic Duty, National Spirit, no criticism types.
no our main enemy is china even kim jung eun say same thing to trump china control north korea behind with out china north korea became demacracy long time ago
There is already room in the current design to accommodate for an internal weapons bay in the future. Not widely known outside the Korean circles but there is room in there - just merely covered up for now and externally housing 4 IRIS-T missiles. The designers planned for future upgrades to turn into a 5th Gen.
@@NWguy83 They are working on a NAVY version of KF-21. The wing area will be slightly larger, a tailhook, a stronger frame and beefier U.S. Navy carrier style landing gears, etc.
The KF-21 vaguely looks like the F-35 in the front, the F-17 un the back, slightly blarger than an F-16 but smaller than all other US fighters. Should orobably mean slightly highrr loadout than an F-16 but still probably operationally in the same class as the F-16, Rafale and J-10 which is what most countries want... Something that's cheap to fly and decently capable,
F 21. Like the success of Korea's F50, the F21 will also succeed. It is a development that covers the retirement of the F4 and the shortage of F15s. It is a task that performs similar missions to the F15 while simultaneously carrying out manufacturing technology, aviation industry base maintenance, engine, and weapon system development.
KAI KF-21 Boramae는 아직도 개발중에있는 전투기죠. 초음속 돌파, 미티어 발사 및 기총사격 성공, 급회전, 연속 루프 기동, 공중급유 성공 등 물론 야간출격을 포함 현재까지 1,000회 이상 출격을 달성하여 이미 개발목표의 반환점을 돌아 나날히 새로운 기록을 갱신 하고 있는 중이죠. 블록 2 와 3버전으로 단계적 진화를 거듭하여 완전 스켈스 매립형(내부 무장창형)은 물론, 무인기를 거느린 복합 전투 운용가능기체로 지속적인 성능 개량을 추진해 나아가게 될 것입니다.
Of course it's a smart idea. It's too expensive and limiting to rely on buying US weapons forever. Korea can't even repair the F-35s that they bought with their own money without US permission. It's part of the contract or something. One of the F-35s they bought went down due to bird strike, and it's been sitting in an airbase forever. Wtf is that. They don't actually own the aircraft if they can't do anything with it without foreign permission. Domestication has much more potential. Also, the KF-21 can be upgraded to a 5th gen platform unlike most 4.5 gen fighters. The airframe is designed for this in mind. Furthermore, people keep saying the F-16 is cheap but the F-16 Viper Block 70/72 is expensive af, and it can't be upgraded to 5th gen. The Rafale also can't be upgraded to 5th gen either, as far as I know. The KF-21 development pipeline shows that Block 3 will have internal weapons bays and stealth coating for the full 5th gen upgrade so it makes perfect sense to invest in a domestic 5th gen platform. It's an impressive and smart move for them to develop this, especially since they domestically developed the core technologies that the US refused to transfer last minute. Lastly, North Korea is the main threat for South Korea, and the North still uses 30 year old MiGs....for which the KF-21 will be more than enough of an answer.
Facts about KF21 that you may not have known but are not important in everyday life - Some people look at the shape of the KF21 and call it the 5th generation. But this is wrong. - KF21 was officially developed targeting the 4.5 generation. Korean Senior domestic officials do not classify KF21 as the 5th generation. - The reason is to replace the aging F4 and F5, and their goal is to create a cost-effective fighter aircraft suitable for the Korean security environment rather than taking on difficult challenges. - And it is a conservative plan to minimize failure. Rather than developing for the 5th generation from the beginning and failing, it is safer to develop the 4.5th generation first and then upgrade to the 5th generation. - Korea introduced the F35 to utilize the 5th generation fighter aircraft. - There are no official plans for a 5th generation upgrade yet. However, development is expected to be possible in the 2030s. - Currently, there is empty space inside KF21. This space was designed with the 5th generation internal weapons bay in mind. - The number of 120 KF21s to be operated by the Korean Air Force has been confirmed. - The Korean Air Force plans to order hundreds more KF21s in the future. - There are plans for a KF21 naval aircraft carrier version. - However, Korea's possession of aircraft carriers is inappropriate for Korea's security environment, so there is no progress in the project. - The Korean government plans to develop its own engine comparable to the F414 by the 2030s. Of course it is will be used in the KF21. currently, thay are focusing on drone engine development. - Mass production of KF21 began on July 10, 2024.
It is a stealth aircraft. Just not deep stealth. It has similar to F-35 stealth when both are using external weapons. Space for an internal bay is already incorporated and it will be enabled at a later point. For South Korea, internal weapons was a low priority because they already have F-35s for deep stealth and their likely adversaries are likely to send large numbers of low capability aircraft. Thus firepower is a much higher priority than deep stealth, to counter large numbers of adversary aircraft that will be outmatched by KF-21 regardless. It is also a 5th generation aircraft. It has all of the features of the 5th gen marketing set, including sensor fusion, networking, automated target evaluation, etc. The fact that the stealth is at a reduced capability point from F-35 doesn't disqualify it from being 5th gen. People lump Su-57 into 5th gen and it has worse stealth than KF-21. Production capability was never a major concern because they have a history of aircraft and component production and access to the majority of required technologies. They only had to develop 10% of the technology because they had 65% already and licensed 25% from the USA. Korea assembled F-5, F-15, and F-16 locally with some localizations. They also built some of their own aircraft, including the FA-50 which is a derivative of F-16 with licensed technology but designed and built by themselves with minimal assistance from LM. The external carrying capacity was designed to match the F-16 that they use in large numbers. This suggests that it will eventually also likely replace most or all of the F-16s.
its a cheaper option. some countries wants to buy cheaper alternatives for their air force. it doesn't matter if they are cheap or expensive, most aircraft frame with limited maintenance will not last more than 20 years anyway. not every country are like NATO that spends a lot in defense
koreans are pragmatic people. not dreamy gigantomanic concepts which aren't suitable for actual needs. thats how samsung, hyundai arose to the top. same with other korean industries. the kf21 fills the gap between f22, f35 and older generation jets.
The "X Generation" term is just a buzzword, stealth fighters are really what everyone is designing. And even then, what counts as a stealth fighter is still subjective
It is said that South Korea's science and technology is lagging behind the United States, which is wrong common sense. South Korea's science and technology are on par with the United States. Because South Korea and the United States are only one country, the science community is actually one body. Many South Korean scientists have Ph.D.s in the United States. So, South Korea's high-tech sector is based on English. There are few barriers to South Korea's immediate acceptance of U.S. high-tech technology. No matter how much the FBI in the United States blocks it, it cannot stop intellectual conversations and discussions between friends. Being a high-quality professional, you don't have to copy top-secret documents. You can get encyclopedia-class information with just one sentence. It is easy to get such high-tech and information because South Korean scientists do not have a lower intellectual level than those working in the United States. Moreover, because South Korean conglomerates are globalized, their research institutes are filled with multinational people. In other words, U.S. technology is South Korean technology. South Korea's concern is that it is a U.S. patent infringement, so it is worrying about how to legally evade U.S. patents, not about acquiring technology. Being behind the U.S. means that the amount of investment and research manpower are too small.. It's not that the technology is low, but it's because there's no money and people. In reality, South Korea is a country like the United Kingdom and Australia, but there are too many Americans who ignore it. Losing South Korea to the United States is like losing the state of California. Anyway, it's right to say that KF-21 is another version of F-22 and F-35 of the United States, which technically reduced stealth function..
Should KF-21 will be next replacement for F-16 operators? F-35 is expensive and not easily sell to some countries like Thailand, so they can expect KF-21 to fill up without big costs.
Maintenance is the issue with US jet, and the price of the KF 21 will improve, Korea will locally design and produce the engine in a couple of years, which will be more advanced than whatever China/NK can make
@@jiraiya86 wt* are you talking about??? F-35A is already at 60-90 mil range. Those +100 mil range are the F-35B and F-35C. The only advantage of KF-21 is it's low life cycle cost(maintenance) than the F-35.
3:06 The use of American Technology hence the lack of transfers of technology is the reason why Indonesia didn't want to fulfill its responsibilities. instead they rather buy the rafale f4
The exclusion of the russians from the export market open the way from new players like kf 21 boramae or the turkish Kaan .and not forget the chinese j35 aparently Egipt expres interest on this aircraft
Take a closer look at the antenna holes and auxiliary air intakes on the KF21 fuselage, which are not designed for the 5th generation aircraft at all, the air intakes are made of Garret, all the wings are not chamfered, and the other openings on the body are not parallel to the wings, which seriously undermine stealth
Build 5th generation cost too much and wasn't sufficient enough technology to build the fighter cheap in early 2010s. They wanted manageable aim. And this was the result. They only left space if it turns to 5th generation.
EVERY modern aircraft is stealth, in the sense that every tactical plane actually in service has received a good deal of RCS reduction measures. It's the final result that vary and this depend from the compromises you are willing to accept in respectively the final level of RCS on a side and instead the flying performances in the other. And the Boramae, almost in the current configuration with four Meteors in semi recessed lodging but a fully stealth shaped exterior sacrifice way less in the first value (RCS) that the Fat Amy sacrificed in the opposite one (flight performances).
This is probably more than adequate against North Korea, and a capable fighter against most regional adversaries. But this may be more of an intermediate development exercise for the Korean aerospace industry, intended from the start to lead to the stealthier future version. Sidebar: when I went to grade school in the US, the only Korean kid in my school was named Boramae. He was a tough guy, but also smart. Not unlike this airplane.
When I zoom out and reduce the size of the image, I can hardly distinguish the KF-21 from some existing aircraft under similar paint schemes. However, no one mentions this; everyone praises its "beautiful design." When things comes to the J-20, the same group of people can strongly criticize it for allegedly copying certain active aircraft, while also claiming that the J-20's shape is odd and that its canards are not stealthy. I really find it hard to understand the judgment standards of some individuals and Western medias.
The Chinese Dictatorship have always not respected Intellectual Property rights Since the Soviet Days. You can even check that the Su-27 agreements is not honored after they got the plans. You can certainly find it in old Russian sources. Not to mention the Ukrainian T-10K I believe==J15 . There is also a lot of Intellectual Property not respected in civilian manufacturing. The Soviets, they are very original in the sense. They don't act like "friends" and then steal technology under the table. This is well known. Many Western, Japanese, South Korean factories in China's Dictatorship also had a similar experience.
knock off fighter are common like the japan's knock off F16 on a dying airframe. This is no different. Osprey is now available to any nation brave enough to use them. Some civilian copy is now available.
We, the Turks, built the KAAN aircraft, and only the engine was outsourced. We did everything on the plane except the engine. Now we are also making engines.
ppl still think it has poor maneuverability because it has f22 design without the thrust vector..without doing more research to find out about the AOA and the Thrust to weight ratio..smh
KF21 only have a liitle edges compare to the last version of f16 so its better purchase cheaper f16 with AESA radar than KF21 with less supercruise, stealth and internal weapon storage😂😂
@@jagodiving ye thats true, but remember its korea's own jet so they get to do whatever the fuck with it unlike American equipments that needs clearance every time they want to mount something thats not American
When the KF-21 reaches the final phase of development as stealth fighter in Phase 3, stealth might be irrelevant at that time.Turkish KAAN might be a quicker response to the world market.
@@fffeee3552 For serving SK defense purpose is your own affair nothing wrong if you decide that way. I just said of the competitiveness in global arms trade that the KF-21 ( of the current development state) will not be much attractive.
lol south korea is a massive military weapon manufacturer. They have tanks, guns, best warships etc, planes . they don't just do for their own use only.

The Boramae has to be the dumbest jet to ever be developed. Taking all the weaknesses of a stealth aircraft but none of the “stealth” part I mean just make a F15EX if that is what they wanted
and how much do you think turning a decades old airframe in to a makeshift 5th gen will cost? high enough that its better to make a new fighterjet with more promising capabilities besides, kf21's flight performance is on par with 4th gen, and RCS is been reduced to a very good amount, closer to 5th gen than it is to a 4th gen.
@ if they wanted to go 5th gen they should have gone all the way. The issue with “stealth” aircraft is that everything else about it has to be sacrificed for stealth. Making a stealth aircraft but attaching external hard points makes no sense when they could have just made a more maneuverable plane with a larger capacity with non stealth frame
@@lolwutyoumad it makes total sense when your opponent is usually a 4th gen, better radar, better RCS, better everything, and like the video saids its designed to do all the stealthy stuff in the future as well, i mean shit already has empty compartments in the belly for future internal weapon bay. besides, even F35, F22s have external hardpoints for different kind of missions, and KF-21 technically do not require wing mounted missiles to do air superiority missions, they are semi-recessed providing much less RCS compared to conventional wing mounted ones
It is all about delivery timeline and pay as you go approach. You make it sound like they have unlimited money and willing to wait longer for a proper 5th Gen to be made from KF-21. If you look into the reason for the KF-21 to be born and the plans they have for it, you will understand why they wanted to make this approach. Note that the Koreans were able to develop this at a fraction of the cost for a company like LM to develop theirs in the U.S. The Koreans already have enough F-35 stealth planes to take on the NK. They don't need a fully 5th Gen KF-21 until these F-35s are old and retired but they do need replacements for their F-15K, KF-16s, F-4 (retired recently) and the F-5s NOW. That is why they want a 4.5 Gen KF-21 for Blocks 1 and 2 now and later Block 3 to house internal WB and go full stealth.
@ less RCS doesn’t mean a thing when a single bolt not 100% screwed in kills stealth on a stealth jet Also, given SK’s defense situation where they need SEAD asap given Seoul is within NK artillery range, they need a better 5th gen fighter bomber to be that first wave

KF21은 4.5세대가 아니다. 스텔스면에서는 5세대 전투기에 미치지 못하지만, 몇가지 사양에서는 이미 5세대 전투기를 뛰어 넘어서 5세대에 근접한 전투기로 보는 것이 맞다. 스텔스 성능 향상과 무인기와의 통합 운영 등 향후 업그레이드 되는 버전들은 6세대급이다. KF21프로젝트는 미국의 기술이전과 인도네시아의 공동투자하에 진행되었다. 하지만, 미국은 ASEA레이다 등 핵심기술 이전을 거부하였고, 인도네시아는 분담금 납부를 지연하고 있다. 그럼에도 불구하고, 한국은 미국이 이전을 거부한 핵심기술을 모두 자체 개발하였고, 인도네시아 분담금없이도 KF21 블럭1을 완성하였다. 무기체제도 거의 모두 해결하였고, 이제 남은 문제는 엔진뿐이다. 엔진의 경우 GE의 특허로 한국의 한화에서 생산한다. 한화가 생산하는 KF21 엔진은 GE의 특허로 생산하기에 해외수출이 불가능하다. 이에 한국은 국산 엔진 개발에 착수했다. 한국은 방위산업에 있어서 만큼은 지나치게 낮춰서 발표한다. 한국이 미사일 개발을 발표했다면 이미 핵심기술을 갖춘 것이고, KF21 개발에 착수했다면 이미 기술을 보유했다고 보는 것이 맞다. KF21엔진을 국산화하기로 발표했다면 엔진 개발의 성공 가능성은 매우 높다. 6세대 버전은 KF21의 블록3는 10년 안에 양산될 것이다.

With the security umbrella provided by the US, South Korea has been able to take a step-by-step approach. Same with KF-21. An evolutionary itinerations. Its flight control system uses the latest technology (sensor-based NDI), which makes itinerations and weapon-integration much cheaper in terms of money and time. KF-21 seems to be the only kind which uses this technology; F-35 uses NDI but model-based NDI.
For South Korea, KF-21 is a must for missiles and UAV Man-Unmanned Teaming (MUMT).
(1) You are not allowed to integrate Korean missiles with US-made fighters; and the US is reluctant to sell too disruptive missiles to SK; and the US missiles are too expensive. South Korea has the state-of-art missile technology. So they think “if we have indigenous fighters, we can develop various kinds of air-launched missiles and integrate them.”
(2) You are not allowed to import foreign made UAVs with big payloads because of the Missile Technology Control Regime(MTCR). As a result, you cannot do MUMT operations with imported F-35s, F-15s or F-16s, because the US fighters interoperate only with the US-made UAVs. So South Koreans think “if we have indigenous…”
And you cannot import avionics, engines, or missiles for high-end UAVs with big payloads (because of the MTCR)
South Koreans are developing turbo engines for high-end UAVs. 1,400 hp turbo-shaft 5,500 lbf. turbo-fan; 10,000 lbf. turbo-fan. Sooner or later South Korea is going to add 16,000 lbf. turbo-fan(with 24,000 lbf after-burner thrust) to its target list.
These high-end UAVs can share the avionics and missiles developed for KF-21.
So the issue of 'stealth-or-not?’ is not that critical. A good 4.x generation fighter KF-21 with defensive EW capabilities or with some level of offensive EW capabilities, which is cheaper than (or equal to the cost of) F-16V Shield or IVEWS… And wlth the same level of hourly operational cost of F-16s… These requirements are more impending or important for South Koreans, as this video says. If they are met, KF-21 will be a bargain. For KF-21 is planned to be much superior to F-16 in almost every aspect.

The U.S. technology base has collapsed in terms of cheap mass manufacture and revolutionary paradigm shifting innovation. No lasers. No hypersonics. No UCAV. This is what happens when you trade cultural homogeny and advancement for third world welfare state immigration policies. Your population becomes dumb and demoralized because they are not allowed to acknowledge differentials in capability and moral capacity as whom they want to live with.
The U.S. financial/economic system will degrade based on their failure to invest in (automan, robotics, genomics) technology, their poor immigration choices and their endless appetite for war. As they fail, through their overeased and over valued dollar and it's poor balance of trade effects on the consumer power of their population PPP, they will fade from the world, bringing home their legions, like Rome, because they cannot sustain same.
With this in mind, the Number One and Two defense technology disruptors Korea needs to invest in are cheap, small, nuclear weapons and ABMD which is both dense and deep in terms of effector spread and stockpiling. Especially where this means laser based systems, in the 1MW range, they will technically spell the doom of manned aviation.
The world sees Ukraine and Israel and understands that the day of the manned jet is passed compared to ever faster and more difficult to shoot down turbine-drones like the Shahed 238. Coupled to highly capable TBM/SRBM weapons which are both mobile and easily hidden. The difference in reaction time, persistence and bus cost are just too enormous to be ignored.
The KF-21 might have made sense, 20 years ago. Today, without internal weapons bays and dedicated emphasis upon full signature management, it is a sportscar version of the F/A-50 with better looks but less justifiable costs. This is a shame because the overal kinematic performance of the KF-21 is probably very good. A 26,000lb EEW, 14,000lbs of internal fuel, and 4,000lb weapons/consumables/aircrew load translates to exactly 1:1 T/Wr at takeoff and this, coupled to the type's refined Raptor shaping probably makes it an excellent maneuvering ACM and sprint capable interceptor.
But if it's not survivable in a late 20-series SAM environment and it's ability to carry heavy standoff munitions lke the Chun-Ryong are limited by it's small wing area, then it is almost certain to be an economic failure. The one thing you can say is that the Daewoo/KAI KF-16Cs are themselves starting to get really long in the tooth. And so having a high end replacement for them as the F/A-50 is the actual replacement for the F-5E, is probably wise.
The issue remains however that the primary enemy Korea faces has serious nuclear capabilities and without the U.S. nuclear umbrella (as we pull back from Asia), the survivability of ANY platform which is dependent on 6-10,000ft of runway as target localized signature driver is...very low.
The Koreans are really smart, I am sure they have a plan in place to accommodate all these factors. It's just a matter of whether they can execute before the coming U.S. collapse. One immediate element of security posture change they could work on would be alliance with Japan which has both the nuclear system knowledge and the 500nm standoff to allow pre-conflict withrdrawal of the ROKAF to the likes of Chitose where, in combination with serious tanker purchases of something like the MRT330, the Seoul government could maintain a viable deterrent capability until such time as they developed missile based alternatives.
Again, the Koreans are really competent engineers and warfighters, it's just a matter of whether they can overcome historical resentments and mistrust to develop regional defense committed partnerships as the United States Aegis fades and not just the DPRK but the Russia and Chinese threats begin to rise.

2:50 In fact, The Korean government faced no financial difficulties in pursuing the KF-X program. Instead, the main challenge was securing future sales opportunities. To address this, Korea sought to attract partner nations willing to invest in exchange for purchasing commitments, offering incentives such as technology transfer, a prototype, and licensed production rights. Indonesia joined the program under these terms but failed to meet its financial obligations and allegedly misused the technology provided during the collaboration.
South Korea has F-35s, so they don't need another 5th gen fighter right away. They will develop KF-21 in phases. Block 1 and block 2 are 4.5 gen fighters. Block 3 will be 5th fighter.
The Rafale and Typhoon is 4.5 and the video says it designed to have a better RCS than that, but below 5th generation. Its between 4.5 to 5 Gen Cheers !
Photonic radars will completely nullify stealth. Yes they will be ground bases radars soon and it will take them a while to also get into aircraft but stealth's days are numbered anyway.
I think that SK has a very good plan. Use KF-21 to learn and test all the systems for developing the full stealth variant. Iron out all the kinks so to say. With NK posturing all the time SK needs a sustainable fleet of aircraft. The high low mix between the two variants makes a lot of sense. Incremental innovation.

I think it is a wise move. There are many countries that don't need highly-capable but expensive 5th-gen fighter jet like F-35. To them, the F-16 or French Rafale are more than enough in the future. Cheap to buy, operate, maintain and capable enough. But alas, they are developed 30-40 years ago and are practically in the last period of their useful platform life. We can not expect much upgrade and support in the long run. KF-21 will fit in the market position of the old and aging F-16's perfectly in 21-st century sky. Even major air force with F-35 will need less expensive workhorse fighter jet like KF-21 to mitigate rising defense budget woe. Korean air force is one of such AF.

Both the dry and wet thrust of KF-21 is higher than that of F-35. 11:45
Isn't the thrust/weight ratio a more useful metric in a comparison?
@well-blazeredman6187 the ratio is even higher since empty weight is smaller. KF-21 is very agile, a multi-role with some interceptor characteristics.
1. Due to the impact of global inflation, the price of the F-16V exceeds $100 million based on the program cost. The F-16 production line, located in Greenville, South Carolina, has a low rate of production, which is difficult to produce 24 units a year.
The price of F-15EX is also more than 120 million dollars. The price of weapons is also skyrocketing due to F-35-class electronic equipment and inflation.
2. The initial mass production cost of the KF-21 Block1 40 units is 80 million dollars per unit based on the program cost.
KF-21 block2 is also scheduled to be mass-produced for 80 units at a similar price, and the mass production of 120 units has already been decided.
3. After the mass production of 120 KF-21s, 32 ROKAF's F-16PB (Block32) must be replaced, and then 131 KF-16U must be replaced with KF-21.
4. To sum up, the KF-21's scheduled ROKAF own demand alone is 270~300 units for the next 20 years.
South Korea's own demand alone will exceed the break-even point, and the problem is how much is left to export.
5. And, it's also interesting whether the reinforced KF-21 to replace the F-15K can appear.

@@PrograErrorExactly, KAI is partnering with Poland to mass produce FA-50 in Europe. It could expand program to make KF-21 in Europe too. Russia is a great motivator to buy it!
I appreciate your objective analysis and explanation.
ROKAF believes that it needs a stealth aircraft with strong electronic warfare capabilities at a lower price and maintenance cost than the F35 and in the future, the KF21 aims to have a built-in electronic warfare capability stronger than the ALQ-200K utilizing MUM-T rather than RCS.
ROKAF doesn't consider stealth capabilities very important and believes that the 60 F35s it already has are enough for stealth fighters.
Very good video, I know that the Peruvian air force plans to buy 24 fighter aircraft at the end of the year and the beginning of 2025 and everything suggests that they will be the KF21, as is known, Peru together with KAI already manufacture the KTP1 in Peru training aircraft and the visit of the president of Korea at the APEC summit held this month in Peru announcing that the industrial services of the Peruvian Air Force will manufacture parts for the KF21 and FA50 , they make it believe that the F.A.P will buy the KF21.
We hope for that in Peru.
Trivia. the Radar is called the APY-016K
it will be developed by Hanwah systems and will use GaN bassed T/R modules, it is water cooled with a peak power target of 30 kilowatts, (APG-77 for the F-22 has a peak power of 20 Kw)
Also the KF-21 has a thrust to weight ratio much higher than the F-35, ranging from 0.78 at max take off weight all the way to 1.69 at empty weight. By comparison the F-35A ranges from 0.72 to 1.48
Being able to push the TWR that high with a light combat load is rather silly. They're also projected to be about the price of modern F-16s. It may actually be a direct replacement for a lot of countries if these can be mass-produced.
If.
the figure I gave is for the entire range from max weight to empty, if we're going to be realistic and imagine the KF-21 entering the merge for whatever reason. dropping all it's drop tanks, with full internal fuel, 4 Meteor missiles, 2 Iris-T missiles, full gun ammo storage, Sniper ATP, the TWR will be around 1.25, thats F-22 levels of power to weight.
This mean F35 is better ,lesser number is mean more thrust per weight.
@ no, its called thrust to weight not weight to thrust, F-22 is 0.83 to 1.62 this is the most powerful fighter in service today.
It carries more weapons than F-16
I've heard from a former Indonesian MinDef employee that KF21 IS actually a 5th gen, but they only declare it as 4,5
bcs 5th gen is already a political domain
With Korea's current technological capabilities, it is difficult to develop a 5th generation fighter at the level of the F-35 with both stealth and network warfare capabilities, but it is fully possible to develop a stealth fighter with stealth and electronic warfare capabilities. Fifth-generation fighters are a more technologically advanced concept than stealth fighters.
Many people in the comments only assume that North Korea is South Korea's enemy. However, China, even Japan, has a conflict factor with South Korea and has room for it to be viewed as a potential enemy. Although North Korea's air power is disastrous, it is not enough to say that South Korea's air power is sufficient, assuming that it has to deal with China and Japan's air power. This is why South Korea is trying to apply stealth technology to KF-21.
One thing is certain. Among the comments on this post, the Chinese are the most fearful and react most violently. It's fun haha
Thanks for the video. Good analysis as always. We, Türkiye, should have cooperated with Korea. It would be more beneficial for both sides.

Not everyone needs to drive a Ferrari to get groceries. A BMW or Genesis is perfectly fine.

Bravo. Great journalism.
This is a smart approach to make a 4.5 gen fighter that becomes a 5th gen for the future variants. This is how Russian jets kept on improving over the years, especially their Su-27 and MiG-29 which has evolved to become Su-35 and MiG-35 today. It's cheaper than the American way to start from scratch that uses a lot of money for R&D and time. Once KF-21 implement internal weapons bay, stealth engine nozzle and radar absorbing material for future KF-21 variants, it will become a legit stealth fighter that compliments the F-35 while being cost effective.
Don't compare Russian 4.5 gen fighters to this, most of them are still at there core outdated tech this is more like a 4.75 gen fighter it's so close to being a 5th gen, and that's reflected in the fact they are making a variety that is a 5th gen fighter using it as a base
@@derekhenschel3191 I'm a pragmatic person and judge the plane based on facts, not emotion. As much as I like the KF-21, calling it a 4.75 fighter makes no sense when it's not even a multirole fighter yet. Currently, KF-21 is only capable of air-to-air combat, it can't possibly compete with Su-35 when it can carry all sorts of armaments and is a matured platform. Of course, this sentiment does not take into account for future variants that will surpass 4++ gen fighters. However, KAI is not there yet and will require some time to develop 5th gen technology

And the more detection technologies will evolve, the less will stealth be relevant.
@@brunol-p_g8800 It's true that low frequency ground-based radar and gallium nitrite radar can detect stealth, but there are several limitations with radars.
1. It can't identify friend from foe especially in combat

3. Decoys and UAVs can be used to overwhelm and confuse the radar tracking system such as SEAD tactic
4. Ground based radars are vulnerable to enemy aircrafts and missiles
5. Ground based radars can't detect low flying aircrafts especially in mountainous areas and cities with tall skyscrapers.
6. Only a handful of countries can make high tech radars that are proven in combat.
7. Due to the earth's curvature, there is a blind spot for radars as it can only detect in a straight line
8. Radars have limited range and does not work well in bad weather especially thunderstorms.

Admittedly, I don’t know as much about this as I would like, but from what I have read isn’t the F 35 thrust Limited compared to what its engine can actually produce. If that is the case, then in the terms of thrust ratio, it’s basically equal to the South Korean fighter. Not to mention the South Korean fighter looks like it’s far more maneuverable than F 35.
Considering the 30-year operating cost, KF21 is not a bad choice from Block 2
The South Koreans had help from US Lockheed Martin (F-22, F-35) on the airframe design which is good and is upgradeable to a stealth fighter. US has barred tech transfer on AESA radar, engines and integration of AMRAAM & Sidewinder air to air missiles. KF-21 Block 1 air defence fighter uses Meteor BVR missiles and IRIS-T short range missiles.
Admittedly, I don’t know as much about this as I would like, but from what I have read isn’t the F 35 thrust Limited compared to what its engine can actually produce. If that is the case, then in the terms of thrust ratio, it’s basically equal to the South Korean fighter. Not to mention the South Korean fighter looks like it’s far more maneuverable than F 35.
Additionally, there’s quite a bit of pressure from Lucky Martin to ensure the F 35 is the only fighter being exported across the world. A great shame in my opinion as it’s better to have more variety in the market.
That's just standard US FMS cartel at work... I believe there are quite a few old aircraft from Avro Canada that got canned from the pressure.
"Pressure in certain aspects can sometimes be illusory. Specifically, pressure against countries with technological prowess and influence is bound to be futile. Such pressure against Korea, which is nearing the completion stage of its engine development, will not be applicable in this situation.
South korea main enemy is north korea and some cities or military bases or airfields are just few miles away with all north korea radar detection are on the south it means that stealth is even an option with tight and congested airspace, being 4.5 generation is the better choice along with having good payload capabilities, supercruise, agility and supermanuevrablity are suited better with advanced data link, jamming, electronic countermeasure.
The North Koreans have old radars as well 🙂 but they do have lots of Arty , Rocket launchers and Ballistic Missiles. Rocket Man Kim. Their Tanks also are museum pieces. However, defensively they are still sound in the current context. South Korea and its allies are not Empires .Invading NK for its land or strategic position. No point. Otherwise they would have Done Anything to take down North Korea. That usually reserved for the likes of Tojo (Imperial Japan) and Leopoldo Galtieri. Dictators that rule with an iron fist, the fatherland/motherland, Patriotic Duty, National Spirit, no criticism types.
no our main enemy is china

china control north korea behind
with out china north korea became demacracy long time ago
China and Russia would be also the main enemies.

Its a Gripen with more powerful thrust and smaller RCS. Its a killer
and it has an internal weapon bay and two engines
@@fffeee3552 two engines dont mean much the f15 have 2 engines but have less range than the Gripen E
All its really lacking are internal weapons bays, and more powerful engines. Both of which will probably be introduced on future block models.
if they can't find the room now, they won't find the room in the future....
@fatdoi003 it would obviously be a slightly larger airframe, like the Super Hornet is compared to the original Hornet.
There is already room in the current design to accommodate for an internal weapons bay in the future. Not widely known outside the Korean circles but there is room in there - just merely covered up for now and externally housing 4 IRIS-T missiles. The designers planned for future upgrades to turn into a 5th Gen.
@@fatdoi003 Already room under the belly. Just covered up for now.
@@NWguy83 They are working on a NAVY version of KF-21. The wing area will be slightly larger, a tailhook, a stronger frame and beefier U.S. Navy carrier style landing gears, etc.
it's a good airplane and probably can grab some market share in the world. just look at Sweden, has its own niche area of pride.
decent fighter yes
its batter then most 4th gen fighters (except f-15)
and i guess its batter then eurofighter (im not sure rafale)
The KF-21 vaguely looks like the F-35 in the front, the F-17 un the back, slightly blarger than an F-16 but smaller than all other US fighters.
Should orobably mean slightly highrr loadout than an F-16 but still probably operationally in the same class as the F-16, Rafale and J-10 which is what most countries want... Something that's cheap to fly and decently capable,

More expensive and more capable, I see it as competitor to the su35 and f15 EX
F 21. Like the success of Korea's F50, the F21 will also succeed. It is a development that covers the retirement of the F4 and the shortage of F15s. It is a task that performs similar missions to the F15 while simultaneously carrying out manufacturing technology, aviation industry base maintenance, engine, and weapon system development.
It looks clean except for gaps in it's control surfaces and weapons

Of course it's a smart idea. It's too expensive and limiting to rely on buying US weapons forever. Korea can't even repair the F-35s that they bought with their own money without US permission. It's part of the contract or something. One of the F-35s they bought went down due to bird strike, and it's been sitting in an airbase forever. Wtf is that. They don't actually own the aircraft if they can't do anything with it without foreign permission. Domestication has much more potential. Also, the KF-21 can be upgraded to a 5th gen platform unlike most 4.5 gen fighters. The airframe is designed for this in mind. Furthermore, people keep saying the F-16 is cheap but the F-16 Viper Block 70/72 is expensive af, and it can't be upgraded to 5th gen. The Rafale also can't be upgraded to 5th gen either, as far as I know. The KF-21 development pipeline shows that Block 3 will have internal weapons bays and stealth coating for the full 5th gen upgrade so it makes perfect sense to invest in a domestic 5th gen platform. It's an impressive and smart move for them to develop this, especially since they domestically developed the core technologies that the US refused to transfer last minute. Lastly, North Korea is the main threat for South Korea, and the North still uses 30 year old MiGs....for which the KF-21 will be more than enough of an answer.
the rafale F5 ( the next generation) will have some modification in it's airframe to be 5th genish
Facts about KF21 that you may not have known but are not important in everyday life
- Some people look at the shape of the KF21 and call it the 5th generation. But this is wrong.
- KF21 was officially developed targeting the 4.5 generation. Korean Senior domestic officials do not classify KF21 as the 5th generation.
- The reason is to replace the aging F4 and F5, and their goal is to create a cost-effective fighter aircraft suitable for the Korean security environment rather than taking on difficult challenges.
- And it is a conservative plan to minimize failure. Rather than developing for the 5th generation from the beginning and failing, it is safer to develop the 4.5th generation first and then upgrade to the 5th generation.
- Korea introduced the F35 to utilize the 5th generation fighter aircraft.
- There are no official plans for a 5th generation upgrade yet. However, development is expected to be possible in the 2030s.
- Currently, there is empty space inside KF21. This space was designed with the 5th generation internal weapons bay in mind.
- The number of 120 KF21s to be operated by the Korean Air Force has been confirmed.
- The Korean Air Force plans to order hundreds more KF21s in the future.
- There are plans for a KF21 naval aircraft carrier version.
- However, Korea's possession of aircraft carriers is inappropriate for Korea's security environment, so there is no progress in the project.
- The Korean government plans to develop its own engine comparable to the F414 by the 2030s. Of course it is will be used in the KF21. currently, thay are focusing on drone engine development.
- Mass production of KF21 began on July 10, 2024.
It is a stealth aircraft. Just not deep stealth. It has similar to F-35 stealth when both are using external weapons. Space for an internal bay is already incorporated and it will be enabled at a later point. For South Korea, internal weapons was a low priority because they already have F-35s for deep stealth and their likely adversaries are likely to send large numbers of low capability aircraft. Thus firepower is a much higher priority than deep stealth, to counter large numbers of adversary aircraft that will be outmatched by KF-21 regardless.
It is also a 5th generation aircraft. It has all of the features of the 5th gen marketing set, including sensor fusion, networking, automated target evaluation, etc. The fact that the stealth is at a reduced capability point from F-35 doesn't disqualify it from being 5th gen. People lump Su-57 into 5th gen and it has worse stealth than KF-21.
Production capability was never a major concern because they have a history of aircraft and component production and access to the majority of required technologies. They only had to develop 10% of the technology because they had 65% already and licensed 25% from the USA. Korea assembled F-5, F-15, and F-16 locally with some localizations. They also built some of their own aircraft, including the FA-50 which is a derivative of F-16 with licensed technology but designed and built by themselves with minimal assistance from LM.
The external carrying capacity was designed to match the F-16 that they use in large numbers. This suggests that it will eventually also likely replace most or all of the F-16s.
If the 🇫🇷 Rafale is a 4.5 Gen fighter, the 🇰🇷 KF-21 is a solid 4.9 Gen.
its a cheaper option. some countries wants to buy cheaper alternatives for their air force. it doesn't matter if they are cheap or expensive, most aircraft frame with limited maintenance will not last more than 20 years anyway. not every country are like NATO that spends a lot in defense

koreans are pragmatic people. not dreamy gigantomanic concepts which aren't suitable for actual needs. thats how samsung, hyundai arose to the top. same with other korean industries. the kf21 fills the gap between f22, f35 and older generation jets.

It is said that South Korea's science and technology is lagging behind the United States, which is wrong common sense. South Korea's science and technology are on par with the United States. Because South Korea and the United States are only one country, the science community is actually one body. Many South Korean scientists have Ph.D.s in the United States. So, South Korea's high-tech sector is based on English. There are few barriers to South Korea's immediate acceptance of U.S. high-tech technology. No matter how much the FBI in the United States blocks it, it cannot stop intellectual conversations and discussions between friends. Being a high-quality professional, you don't have to copy top-secret documents. You can get encyclopedia-class information with just one sentence. It is easy to get such high-tech and information because South Korean scientists do not have a lower intellectual level than those working in the United States. Moreover, because South Korean conglomerates are globalized, their research institutes are filled with multinational people. In other words, U.S. technology is South Korean technology. South Korea's concern is that it is a U.S. patent infringement, so it is worrying about how to legally evade U.S. patents, not about acquiring technology. Being behind the U.S. means that the amount of investment and research manpower are too small.. It's not that the technology is low, but it's because there's no money and people. In reality, South Korea is a country like the United Kingdom and Australia, but there are too many Americans who ignore it. Losing South Korea to the United States is like losing the state of California. Anyway, it's right to say that KF-21 is another version of F-22 and F-35 of the United States, which technically reduced stealth function..

인도네시아는 돈이 없으면 계약파기해주세요~~
Key question for me was never answered: why does it look like the F22?
LM was an advisor. It literally looks like a hybrid between f35 and f22.
Should KF-21 will be next replacement for F-16 operators? F-35 is expensive and not easily sell to some countries like Thailand, so they can expect KF-21 to fill up without big costs.
Mil mi-26 please 🙏
The KF 21 is going to cost 71 mil per plane the f35A is 102 mil and you get better everything. I am not a fan of the USA but let's be real about this
Maintenance is the issue with US jet, and the price of the KF 21 will improve, Korea will locally design and produce the engine in a couple of years, which will be more advanced than whatever China/NK can make
@@jiraiya86 wt* are you talking about??? F-35A is already at 60-90 mil range. Those +100 mil range are the F-35B and F-35C. The only advantage of KF-21 is it's low life cycle cost(maintenance) than the F-35.
102 mil is just the tip of the iceberg. us jets maintenance is very expensive
You also need to consider the maintenance costs.
Because you are japanese>>domo. 100mil is no option price

Do the j35 nect
The exclusion of the russians from the export market open the way from new players like kf 21 boramae or the turkish Kaan .and not forget the chinese j35 aparently Egipt expres interest on this aircraft
Take a closer look at the antenna holes and auxiliary air intakes on the KF21 fuselage, which are not designed for the 5th generation aircraft at all, the air intakes are made of Garret, all the wings are not chamfered, and the other openings on the body are not parallel to the wings, which seriously undermine stealth
Build 5th generation cost too much and wasn't sufficient enough technology to build the fighter cheap in early 2010s. They wanted manageable aim. And this was the result. They only left space if it turns to 5th generation.
EVERY modern aircraft is stealth, in the sense that every tactical plane actually in service has received a good deal of RCS reduction measures. It's the final result that vary and this depend from the compromises you are willing to accept in respectively the final level of RCS on a side and instead the flying performances in the other. And the Boramae, almost in the current configuration with four Meteors in semi recessed lodging but a fully stealth shaped exterior sacrifice way less in the first value (RCS) that the Fat Amy sacrificed in the opposite one (flight performances).
Boramae(보라매)는 어린 falcon?
길들일수 있는 새끼 falcon을 뜻합니다.
정의하자면..
Boramae가 시작이라는 뜻이죠.
Its just a good 4.5 gen fighter.. a competitor to F-15EX and not F-22..
Currently the 174BS and 260 missles are probably in production already.
This is probably more than adequate against North Korea, and a capable fighter against most regional adversaries. But this may be more of an intermediate development exercise for the Korean aerospace industry, intended from the start to lead to the stealthier future version.
Sidebar: when I went to grade school in the US, the only Korean kid in my school was named Boramae. He was a tough guy, but also smart. Not unlike this airplane.
When I zoom out and reduce the size of the image, I can hardly distinguish the KF-21 from some existing aircraft under similar paint schemes. However, no one mentions this; everyone praises its "beautiful design."
When things comes to the J-20, the same group of people can strongly criticize it for allegedly copying certain active aircraft, while also claiming that the J-20's shape is odd and that its canards are not stealthy.
I really find it hard to understand the judgment standards of some individuals and Western medias.
The Chinese Dictatorship have always not respected Intellectual Property rights Since the Soviet Days. You can even check that the Su-27 agreements is not honored after they got the plans. You can certainly find it in old Russian sources. Not to mention the Ukrainian T-10K I believe==J15 . There is also a lot of Intellectual Property not respected in civilian manufacturing. The Soviets, they are very original in the sense. They don't act like "friends" and then steal technology under the table. This is well known. Many Western, Japanese, South Korean factories in China's Dictatorship also had a similar experience.
Drones make 4th gen fighters ob see olete.
knock off fighter are common like the japan's knock off F16 on a dying airframe.

Osprey is now available to any nation brave enough to use them.

We, the Turks, built the KAAN aircraft, and only the engine was outsourced. We did everything on the plane except the engine. Now we are also making engines.
Engines are literally the most complex thing, growing single crystal blades ain't no joke

@ if they wanted to go 5th gen they should have gone all the way. The issue with “stealth” aircraft is that everything else about it has to be sacrificed for stealth. Making a stealth aircraft but attaching external hard points makes no sense when they could have just made a more maneuverable plane with a larger capacity with non stealth frame
@@lolwutyoumad it makes total sense when your opponent is usually a 4th gen, better radar, better RCS, better everything, and like the video saids its designed to do all the stealthy stuff in the future as well, i mean shit already has empty compartments in the belly for future internal weapon bay.
besides, even F35, F22s have external hardpoints for different kind of missions, and KF-21 technically do not require wing mounted missiles to do air superiority missions, they are semi-recessed providing much less RCS compared to conventional wing mounted ones
It is all about delivery timeline and pay as you go approach. You make it sound like they have unlimited money and willing to wait longer for a proper 5th Gen to be made from KF-21. If you look into the reason for the KF-21 to be born and the plans they have for it, you will understand why they wanted to make this approach. Note that the Koreans were able to develop this at a fraction of the cost for a company like LM to develop theirs in the U.S. The Koreans already have enough F-35 stealth planes to take on the NK. They don't need a fully 5th Gen KF-21 until these F-35s are old and retired but they do need replacements for their F-15K, KF-16s, F-4 (retired recently) and the F-5s NOW. That is why they want a 4.5 Gen KF-21 for Blocks 1 and 2 now and later Block 3 to house internal WB and go full stealth.
@ less RCS doesn’t mean a thing when a single bolt not 100% screwed in kills stealth on a stealth jet
Also, given SK’s defense situation where they need SEAD asap given Seoul is within NK artillery range, they need a better 5th gen fighter bomber to be that first wave

KF21은 4.5세대가 아니다. 스텔스면에서는 5세대 전투기에 미치지 못하지만, 몇가지 사양에서는 이미 5세대 전투기를 뛰어 넘어서 5세대에 근접한 전투기로 보는 것이 맞다.
스텔스 성능 향상과 무인기와의 통합 운영 등 향후 업그레이드 되는 버전들은 6세대급이다.
KF21프로젝트는 미국의 기술이전과 인도네시아의 공동투자하에 진행되었다.
하지만, 미국은 ASEA레이다 등 핵심기술 이전을 거부하였고, 인도네시아는 분담금 납부를 지연하고 있다.
그럼에도 불구하고, 한국은 미국이 이전을 거부한 핵심기술을 모두 자체 개발하였고, 인도네시아 분담금없이도 KF21 블럭1을 완성하였다. 무기체제도 거의 모두 해결하였고,
이제 남은 문제는 엔진뿐이다. 엔진의 경우 GE의 특허로 한국의 한화에서 생산한다. 한화가 생산하는 KF21 엔진은 GE의 특허로 생산하기에 해외수출이 불가능하다.
이에 한국은 국산 엔진 개발에 착수했다. 한국은 방위산업에 있어서 만큼은 지나치게 낮춰서 발표한다. 한국이 미사일 개발을 발표했다면 이미 핵심기술을 갖춘 것이고, KF21 개발에 착수했다면 이미 기술을 보유했다고 보는 것이 맞다.
KF21엔진을 국산화하기로 발표했다면 엔진 개발의 성공 가능성은 매우 높다.
6세대 버전은 KF21의 블록3는 10년 안에 양산될 것이다.
