Brahmos is the Indian version of the Soviet/Russian Yakhont. It is co-produced by India and Russia. It is Intergated Ram Jet. (liquid fuel) 'Integrated' means that the space for rocket booster later turns into liquid ramjet combustion chamebr. In the 1990s, Russia could not pay back its debt to South Korea. So they sold some technologies for tanks, radars, and IRJ(integrated Ram Jet). South Korea absorbed these technologies and have come out with much-improved version. K2 Main Battle Tanks (MBT) has Russian touch in it. Korean indigenous missile defence (Chunggung and LSAM with indigenous AESA radar) have a Russian touch too. In 2021, South Korea test-fired land-launched anti-ship IRJ supersonic cruise missiles. Koreans call it 'Kyakhont'(Korean Yakhont). Everrything is in veil. Here in South Korea, some weapons are in veil. Especially those which means something to China. For example, some models Hyunmoo 4 is known to have 2 ton war head with 800 km range. This means it can fly 2000 km with a lighter war head. This range covers every corner of China's sensitive localities. So the exact info about Hyunmoo4 is not opened I guess they can develop submarine launched 'Kyakhont' without any difficulty if need be. As for supersonic cruise missiles, South Korea seems to be more focused on an air-launched version. Maybe they want for their indigenous fighter(KF-21) something like AARGM-ER (a anti-radar missile) which the US will never sell to South Korea, since this region is too hot.
not many people seem to know of the original P-800 Yakhont compared to the Indian Brahmos, which is ironic consider the latter is a clone of the former i think the Indian media is to blame for this, as they got a much broader contact with the English-speaking internet world, and India sounds very enthusiastic to promote its anti-ship missile too so most people will assume a supersonic ramjet anti-ship missile with that silhouette was a Brahmos instead of a Yakhont here in Vietnam, foreign press (mostly Indian) will occasionally brings up VN as a "potential Brahmos buyer", despite VN having bought & been operating the P-800 Yakhont missile (of the K-300-P coastal batteries) for years now
i think the K-Yakhont might be a direct clone of the P-800 Yakhont too, while its capability might even come close to the domestic Russian 3M55 Oniks version (maximum range ~600-800km) once the reverse-engineered technology is understood and mastered, the K-Yakhont or the Brahmos could thereotically be tweaked and improved above the downgraded export Yakhont, and even more likely to be crafted from domestically-made parts
I didn't realize you had a youtube channel Mr. Sutton! This is a wonderful development, I'm quite happy to see this pop up in my recommended videos. Only 3.08k subscribers, that's positively criminal... I'll do my part to remedy that.
Several wrong information is found in the video. (There are more errors but I can't mention them here.) 1. Canto Decoy is not accepted for KSS-3. 2. According to the submarine squadron operation policy of the ROK navy, every "Batch"s has 3 boats, not 2. So No.3 boat is the same as its nameship, Dosan Ahn Changho.
Ohhhh, it's war then, DAH DAH DAAAAAH! Sutton returns fire🔥but misses the Seeker, uh oh there goes the pens & a ruler from the Seeker & scores a direct hit on the Sutton's pin board, Sutton hides behind the sofa & the Seeker drops a History of Subs book but misses Sutton who has crept behind the Seeker who is in the bath with support Navy vessel the Bobbing Orange Duck & Sutton fires a Chocolate Orange that then splits it's segments & scores a direct hit on the Seeker who sinks to the bottom of the bath. Will he be rescued.. TAA DAAAAH, tune in next week folks..
Absolutely brilliant video! I think you have grown much more comfortable with the format, and it really shows! Really interesting and ground-breaking sub. South Korea have surely and steadily developed an enormous capability in sub design and development, if you consider the small time frame. Really impressive armed forces. Should be an example for everyone else, who can only think in the short-term.
I served in ROKN for 6 as a LT. I was asked to join submarine force but I was smart and declined 😆 Anyways currently serving in USN for past 5 years. I must say ROKN is a capable navy and with introduction of new submarines I wish my old navy will continue to grow. "바다로! 세계로!" "To the sea! To the world!"

@@_Alfa.Bravo_ Thank you for your service to great nation! I had an opportunity to meet one of German Navy's Fregate many years ago near Somalia while conducting counter piracy operation with CTF151.
Note for the cruise missile: it is rocket-powered, sort of. The booster (the part spewing fire while going up, but is missing from the level flight picture) is basically a small rocket, most likely solid-fueled. It sent the missile up and away until it reaches cruising speed, and then fall off. However, for the rest of the way, the missile is either powered by a small turbojet/turbofan. these are jet engines that sip your regular/special mix jet fuel and combine it with oxygen from the air to generate thrust. Not as high thrust, but way longer ranged for the size.
Excellent analysis, Aaron at channel sub brief always praises your work, I have read your work and stumbled upon your YT channel and subscribed immediately before watching a video, unparalleled content sir thank you. Covert shores and Sub brief are my go to for naval news, please keep up awsome work.
6 brought for Canada off the shelf, that is, to be brought directly from skorea instead of messy licensed production in Canada should be an ideal naval power boost to Canada and a safe bet to replace ageing victoria class submarine. May be s-vls can be replaced by mk41vls to fire tomahawk missiles.
@@matthewtulberg2252 Virgina class has a Vls (probably mk41) which was considered for Isaac Peral S80+ submarines initially.... Southkorea has k-vls which is something they are not willing to share for export.
So Japan just announced the development of Cruise missile launch capability from their submarines, 3 moths after this video. The moment I read that article I immediately remembered Sutton’s words of a new trend. Amazing insight.
While it very likely has a short burning booster rocket motor to propell it to a starting altitude, the Hyunmoo-3, just like the Tomahawk, has a turbofan engine which propells it over the vast majority of the cruise.
The miniature turbojet engine on the Hyunmoo-3 is copied from a Russian design that the South Koreans got from Project Brown Bear, a project where Russia gave South Korea a lot of Soviet military technology as a way to pay off debts.
@@mysygisun3335 Yes I understand that. Like the Harpoon, the Hyunmoo-3 uses the turbojet for most of the trip and then the rocket for the terminal phase.
Really enjoying your informal format I think I find it reassuring that someone knows their subject so well and does make for an excellent 'brief' :) Ta Merry chrimbo B
Question is are they able to move "Evade" Much faster than is clamed. Flat Battery real fast or the ability to to keep sustained high speeds when needed? I know folk's can do math with drag equations
At 9:04 mark you mention Brahmos supersonic missile as a potential armament for KS-III if it's bought by the Indian Navy. You might consider revising based on South Korea's recent testing of its own supersonic missile based off of the Russian Yakhont/Oniks, the same predecessor to Brahmos.
The cruise is powered by turbofan. It's very similar to Tomahawk. Cold launch and rocket booster and turbo. The range is 1500 km. They are working on 3000 km model . .but in a very low profile in order not to push China too hard. . Since the peninsular is too hot, the US has not sold the most destructive missiles such as: Tomahawk, AARGM-ER, LRASM, or JASSM-ER. Anyway, they have been working on missiles like these.
These aren't just unscripted chats. These are mini lectures from someone who is clearly expert in their subject matter. You're passing info not arguing a point. You only need to structure if you're trying to go for a conclusion, I feel. You're clearly well informed enough about what you're saying that you don't need a script. The other time you need a script is if you don't know a topic sufficiently that you need notes prompts and reminders. Which you clearly don't. So don't worry.
so, regarding the relation between Japan and South Korea, even though there exist, on one hand, historical feud & mild hostility, and on the other hand, a common threat against china & north korea, plus the common ally - the USA, most of South Korea's drive against Japan's submarine force might just be for national prestige ("we can build a much better submarine than them") rather than any possible confrontation between South Korea & Japan
Well done content. Thank you. Since you asked for a suggestion. I would be interested in a series that describes the typical ways different submarines would go about finding and identify and then attacking each other. Example kss Iii. Vs a Russian equivalent. Or US vs China. Tactics likely to be used? Possible outcomes? A versus series of videos in essence. Regardless. Great work!
Mr. Sutton, one thing I don't understand is why the Soviet/Russian Typhoon class is constantly referred to as Akula. That is an error. The Akula was a Soviet sskn that was the replacement ,or at least the logical next step for the Alpha class. I have 3 resources which are impeccable. #1. Tom Clancy: Red Storm Rising. #2. 2 close family friends who Nuke sub officers in the US Navy in the 70's to mid 90's. One was the 1st XO assigned to the USS Ohio. He later became a Captain 0-6, of his own Trident Boomer. #3. Last, but not least, one of my best friends from high school who was the senior fire control technician on a LA Class, the Hyman Rickover. All 3 said the Typhoon was never referred to as the Akula, while they were in. Did something change?
There are two Russian subs called Akula The Pr.941 is called Akula (meaning shark) by the Russians. NATO reporting name is TYPHOON. To see why,, see www.hisutton.com/The%20REAL%20Red%20October%20-%20Typhoon%20SSBN.html The Pr. 971 is called Shchuka-B (meaning pike) by the Russians. NATO gave it the AKULA designation. This is the one you have heard about. I tend to use the military/navy norm of using capital letters for NATO code names and lower case for regular names. But it is hard to do always, especially when trying to write for a wider audience
you keep saying AIP produces hydrogen that they then get rid off but that doesn't make sense. a fuel cell needs both oxygen and hydrogen and combines them to water, that process produces electricity.
Just noting that the Japanese subs can fire harpoon anti-ship missiles from their torpedo tubes. I would think that Japan should add VLS to their subs as well, they will need that option.
well they probably need targeting pods on their multirole fighters, some land attack missiles, some method to preemptively strike missile launch sites, oh but wait, they are prohibited from possessing offensive weapons. Their navy is basically the anti submarine support fleet for the seventh fleet.
Japan is in a vulnerable position, being threatened by North Korea and China, and possible Russia with nuclear attack. They will not say it, but they cannot rely on the US for nuclear deterrence going forward. That is especially true with the Biden administration in charge- or any future one like it. Yes, Afghanistan points this out more clearly. Japan will need to eventually create their own independent deterrence. Right now, they are trying to keep the US as a close ally no matter the US administration, out of necessity- while trying to pull the US toward their thinking on the threats. If China does what it threatens in the press, invade Taiwan and simultaneously does a limited nuclear strike on Japan, what happens. Biden does diplomacy to prevent escalation to the US is most likely- capitulation, treaties and agreements ignored. We already see that they are good at ignoring US laws. Taiwan and Japan will be abandoned. The only defense Japan really has now is their Aegis (BMD) destroyers, and possibly drawing in the US, from the fallout on US bases in Japan. Regardless of laws, from a military perspective they need their own deterrence. China is probably calculating this scenario as well, making Japan’s stance on nuclear weapons in-affect destabilizing. The VLS on their Subs would be the best step forward for a survivable counter strike ability. Even having a conventional strike ability with SLBMs or cruise missiles on their subs sets the stage and provides some deterrence. The new PM of Japan, Kishida, is already pushing for strike weapons. They could easily modify their anti-ship missiles as land strike missiles (the ASM-3A, or the in-development missiles: Type 12/Type 17 increased range missiles, and the hypersonic ones they are working on as well). The latest version of the US SM-6 missile will also have a surface strike ability, and most likely added to their destroyers. Really, what you consider to be an offense weapon can be argued to be a deterrent and thus defensive, the extreme example is the MAD doctrine we have all been living under.
@@douglasstansfield3957 Unfortunately, Prime Minister Kishida was cautious about deploying nuclear submarines. Also, deploying weapons capable of attacking the ground is probably impossible due to the obstruction of the Japanese media and anarchist opposition, which are hostile to the government. Also, the majority of Japanese people are afraid to return to militarism, so there is a strong sense of refusal to excessively strengthen their armaments. Furthermore, it is necessary to make major changes to Article 9 of the Constitution in order to acquire the ability to attack enemy bases, which is quite difficult.
I would like a video on how do submarines navigate while under water. I know the case of a US sub that ran into an underwater mountain at 25 knots (I've seen pictures of what the sub looked like afterwards). One of the sailors, thrown into a door, died. I would like a short description of Low Alloy High Strength (I think this is what it's called) and why it was used. It worked well for that sub.
There was a VERY recent development of a quantum IMU (inertial measurement unit) which is just an accelerometer so precise it can actually give you your accurate position if you know the initial position so presumably no drift. It was developed specifically for naval use when there is no access to GPS signals and to me that screams submarine. It seemed pretty huge though so I don't know about retrofitting existing subs with it.
@@MrRolnicek Thank you, Roinicek, but my question was specifically for the subs without Space Station equipment onboard. The regular subs of today, which patrol submerged for months, without seeing sky OR the bottom relief. How did they know where they are when submerged? How did they know where they were heading?
@@SerbanOprescu I get it but I don't know much about that so all I could contribute is the near future. I believe the current ones use gravity measurements as part of their navigational toolkit but that's about all I can tell you.
It's very interesting. By the way, do you think the Korean Navy will operate supersonic cruise missiles and cruise missiles in addition to SLBMs in the VLS of KSS-III class submarines?
@@HISuttonCovertShores Thank you for your answer. But the reason I asked you that question is because I read an article that you contributed to the Navy News. In the drawing, it is described as if a supersonic cruise missile is operated in the VLS of Dosan An Changho. By any chance, did you take into account the Indian project? And you seem to think positively about AIP submarine. However, at the condition of the highest speed under water, the maximum cruising time is still significantly lower than that of nuclear-powered submarine. Nevertheless, can AIP submarines be viewed as a game changer?
Sorry, are you referring to the Brahmos missile which is illustrated? There are three missiles in my illustration, talk: Hyunmoo-4-4 - SLBM, I would think the main weapon going forward Hyunmoo-3C - SLCM, like Tomahawk. Low-supersonic - I do have an error/oversight in not mentioning the jet phase but cannot edit the video Brahmos - mentioned in context of P75I competition Re AIP, to clarify, I think that it is a game-changer to combine modern AIP with a VLS, and more so because of the small SLBMs. AIP has both pros and cons over nuclear. This video discusses pros and cons of AIP. th-cam.com/video/c2QS_aEsVuw/w-d-xo.html This video was made before the AUKUS announcement. I haven't changed my view on the significance of the KSS-III Hope that this helps.
Supersonic cruise missiles will be launched with torpedo tubes. The Korean version of Brahmos has been specially miniaturized for torpedo tube launches.
If Korea happens to develop nuclear weapons they’ve got a second strike platform ready to go. That they can make use of it conventionally in the interim gives them deniability and export markets. Well done.
I dont expect to see Brahmos in S.K service when they just tested there own hypersonic anti ship missile they will adapt that to be sub launched aswell and interestingly it looks quite similar to Brahms or oniks anti ship missiles.
The Brahmos was put on there for the benefit of the Indians, who are also looking for an API sub with VLS. Export market, which the Koreans are keen on.
@@miraphycs7377 super long distance missiles are a bit tricky since they may not hit their intended target and hit an oil tanker or a commercial cargo ship instead. Shipborne radar on missiles are not particularly choosey.
Polish MoD Mr. Błaszczak announced beginning of program ORKA - purchase of Polish Navy submarines. KSS submarines definitely will be in scope of interest.
@@F_Tim1961 The Russian original fielded missile tubes on subs required repair before reloading. Pretty sure it took the US some time to get the tube engineering right so the pressure of rocket nozzle blast wouldn't mess things up.
We trust the quality of production made by sokor, indeed wish to acquire 3 unit of KSS lll sophisticated submarine for defense and survielance at the sea.
@@HISuttonCovertShores I watched that but it didn't cover the game changing aspect of it. JMSDF (Japanese) claims 100 minute recharge time at snorkel depth every 10 days, which equates to having to use diesel engine less than 1% of time, without even taking into account AIP usage. They also claim ability to cruise at 20 knots underwater for sustained period, using only lithium ion battery. Also, detailed discussion of Stirling (heat) engine vs. fuel cell AIP would have being informative.
@@mrteacher1315 wondering/ hoping you can provide a cite for what you say is the game changing 100 minute recharge time @ snorkel depth every 10 days for their LIBs. If true that does seem game changing and would seem to obviate the need for an AIP system. Thx in advance ..
@@brodieboy3 I believe I read it in an analysis by JMSDF and/or defense ministry study when they decided to go 100% lithium-ion battery instead of AIP+lithium-ion battery after they did feasiblity studies. This was several years ago. Quick search yielded an article in The National Interest titled "To Counter China, The Japanese Navy Is Investing In Submarines." Then in the article, you'll see the following sentence: "Japan has already studied optimizing the snorkel for the diesel engines on the Soryu class. Though LIBs are faster charging, given the SS-29’s huge planned battery capacity, the improved snorkel may be necessary to avoid taking longer than the claimed 100-minute charging time for the LIB-equipped Soryu." "The SS-29 class will be built around the extraordinary battery capacity offered by lithium ion batteries (LIB). At the blog Submarine Matters, analyst Peter Coates speculates the new design might boast up to ten days cruising submerged." It's possible that 10 days might not be correct for converted Soryu. There are some calculations showing 6-7 days instead.
I think one thing that has to be said is the North Korean fleet is very old but the crews or modifications from all available evidence amazingly good, especially taking into account that during a South Korean Anti Submarine Warefare excerise, so everything is being closely monitored a North Korean sub just decides to go into the middle of the pack sinks a South Korean Corvette leaves and isn't detected once.
Can you go back to no ads for this? I like to listen to these before bed and the ads really disturb my peaceful absorbing of open source sub intel. I have to switch back to drach when the ads come on.
Cruise missile is variant of en.wikipedia.org/wiki/Hyunmoo-3 . I think Russians at least conceptualized similar layout for Amur Class, so did Swedish Kockums for A-26. In any case, hull diameter for non-nuclear sub will limit size thus range-payload of the missile and cruise missiles are far less conspicuous. Especially ballistic missile will be detected early over flat sea.
My guess is SK need the fast delivery munitions for its submarines lurking outside the NK coast to neutralize NK nuke SLBM launchers before the launch. Cruise missiles would be too slow for it. I doubt NK has capability to hunt subs outside its litoral water.
Another brother of Yakhont and Brahmos family. Got smaller and faster and longer range from older generation but Russian/Indian technicians will upgrade the missile with better spec. then this.
The VLS in the A-26 is only an offering, no customers currently and no boats built. The first KSS-III was laid down in 2016 (and would have been designed years before). The A-26 models with VLS were first shared in 2017(?)
wonder, how a bigger KSS-III class or a larger Type 212B & Type 216 class of SSNs would fare against it's rivals . . . let's say, a fleet of 10 brand new KSS III class 5,683 ton (6,234 ton loaded) stealth guided missile fast attack submarine powered by iFuelCell™ FC3 AIP-HYBRId® system . . . armed with 8-cell SYLVER A50 VLS built into the forward bow section of the submarine hull . . .
Hi. fantastic video however. I just have one problem that I would like you to explain.. The question is why do you not seem to differentiate between North Korea and South Korea until you are half-way through your lecture, are you trying to maintain that they are the same country!!! Sorry no offenses meant, just curious about your preference?
They obtained a license from TKMS so it very likely is based on the 214. it even looks like it and uses almost identical PEM fuel cells, same sonar, sensors, etc. Even the change to lithium ion is in line with U212CD.
Nope. They license built 209 and 214 then moved onto bigger and better. Only sub with AIP and lithium ion batteries are made in Japan and Korea. One of main reason why Canada is considering subs from these 2 countries, German subs too small and underwater time not long enough.
@@leedavid408 the U212CD also uses lithium iron batteries. And btw. The U216 that was offered to Australia was even bigger (90m and 4000t). That Germany uses the 212is small is because it has to operate in the Baltic Sea, which is basically a lake. Size is not the problem. It‘s easy to build a big sub.
212cd to be delivered in 2029 & 216 a concept design Australia rejected. In other words non existent German subs with state of art AIP and lithium ion batteries which korea and Japan are operating/marketing presently.
@@leedavid408 it says in the Wikipedia article about the KSS-III (with reference) that it is based on the U214. The U212/214 was the first using PEM fuel cells. I give you that Japan was first to introduce lithium-ion batteries on subs in 2023. However, the U212A being retrofitted as they have been testing it for many years. Hardly news then. Still your case about size is irrelevant as there is no technology behind making subs bigger. An whether they are 80m or 90m is not a leap in innovation. The U212/214/218 have all been sold extensively. So that Canada is considering Korean and Japanese subs is normal. And I am sure they are good. But for the same reason India is currently considering the TKMS subs.
To be honest switching from fuel cell to lithium ion batteries will be a challenge for Germany 2020 top lithium ion battery manufacturers market share 1. LG Energy Solution - 28% (S.Korea) 2. CATL - 25% (China) 3. Panasonic - 17% (Japan) 4. BYD - 9% (China) 5. Samsung SDI - 7% (S.Korea) 6. SK Innovation - 5% (S.Korea)
Yeah - Saab offers lots of things in their PR brohures .. but they've not even built a single new sub since taking over Kochums in 2014. The A26 just got delayed for the 3rd time - this time by an additional 3 years with the 1st boat (which of course won't have a vls module) is now scheduled for 2027 .. after originally being promised in 2019, then 2022, then 2024 and now 2027 .. will it ever be delivered?
This submarine is the best submarine for any nation who has access to nukes but doesn't have them. Atm.. Going thing missing is Nuclear powered which is needed for Canada which is looking for a Multirole intelligence special forces multiple cruise missile cells torpedos ballistic missiles all nuclear capable and double hull nuclear powered for Arctic operations and long range
The Hyunmoo-4 is essentially a Russian Iskander missile. That Brahmos looking thing is essentially a Russian Oniks missile, but made smaller so it can be fired through a torpedo tube.
correction, based on Islander design but not entirely similar, just that design is. Rocket system is very similar but it's system and electronics are very different.
While it's perfectly natural that ROK dislikes Japan, I can't see how they've actually thought of them as a *threat* in the past 75 years (especially with the USN right there).
75 years after 50 years of forced colonization and occupation by japan when it illegally annexed the country, murdered the last surviving royal family member, outlawed the korean language and korean names, and then confiscated private land to be owned by imperial army and emperor, yea that one. I wonder how they can see japan as a threat? your right, totally kawaii people.
Probably not with both nations ally with US and as long as US dominance in western Pacific, but you just can't guarantee 10 to 20 yrs in the future with resurrgent China.
the presence of the united states navy (7th fleet) you expect to be some form of reassurance. North Korea invaded south korea when the US was the official protectorate of the country, and when it had ground forced in the country. The US had its soldiers in the country during the CIA sanctioned military dictatorship. Democracy was not provided by US soldiers, but by korean citizens and students protesting daily and being beaten and disappeared for over thirty years while being protected by the US and when several divisions of US army were present. same situation when the SK president was assisinated and a second military dictatorship installed, after getting green light from US intelligence and diplomats. So your thinking isn't shared with any koreans on earth.
I really doubt it (SK submarine ) has LOX as an oxidant for the F cell, as opposed to highly compressed oxygen as per what the GErman type 212 uses. LOX means you Have to use up the Lox from the get go... if you don't it will boil off and it will have to be released or the pressure vessel will burst. This automatically means a trail of oxygen bubbles in the sea which ain't smart as a stealth weapon . Moreover you have to warm it up before it goes to the fuel cell This will require electric power or reheat from the fuel cell . It also makes Oxygen refuelling at sea next to impossible (as opposed to compressed oxygen refuelling ) . TE Fidler
Type 212A uses LOX in insulated tanks above the pressure hull (underneath the GRP fairing). The LOX evaporator runs on waste heat provided by the fuel cell reaction.
Lets use hypergloic reaction, as in high test hydrogen peroxide & doped Kerosene/Diesel to drive a pair of 10 Mwatt class turbines. Compact, refuel at sea possible, reliable, simple, robust & high power to weight ratio of machinery, fast recharge for solid state li ion batteries. Power levels approaching not quite SSN flank speed but sufficent for long range (1000+ nautical miles) relatively fast 20+ kts submerged strategic deployments or very fast recharge 30 to 40 minutes or less.
@@kevinyaucheekin1319 That's efficient, but then you get SSN noise levels without SSN capabilities. For SSK, especially littoral types, fuel cells are absolutely silent; tie to Lithium Polymer batteries for sprint speed and you have a sonic black hole that can get up and move if need be...
I lived in So. Korea for a year. I can tell you that they absolutely hate Japanese there. I recall being in a large restaurant in Seoul when everyone in the building stopped talking at once. My friends and I asked the waiter what happened so suddenly. He responded that a Japanese woman walked in and Koreans hate the Japanese because of the unspeakable things they did in WW-II when they held the country hostage.
As I can say as S.Korean, S.Korean doesn't hate Japanese visitor, We just despise Japanese government and their Arrogance without truly apologize although they slaughtered so many Korean. They always interrupted to unite Korean. Through History. to prevent same 18 century situation, S.Korean shall prepare against Japanese invasion when will be out of control from US someday.
The ECA group and Babcocks have certainly provided assistance as the story on this sub mentions. RoK can take great pride in what has been designed and built. Building 27 of these subs in such a short space of time shows a fantastic ship building ability for such a small nation.
AIP allows the disease engines to run underwater, which in turn produces electricity 4 batteries & thus increases submerged range w/o surfacing or snorkeling.(can't have combustion w.o air)
That's the snorkel system. The AIP is fuel cell. A reaction of LOX and LH thru a membrane to produce water and power. The process can be reversed by using the diesels to produce power to break up water.
@NorthForkFisherman I said "w/o (without) surfacing or snorkeling". But yes, I'm aware but thankyou anyways good sir. Basically a means for power, propulsion, & crew needs(air, water, electricity) w.o using diesel engine(or supplementing)
@@jdogdarkness And a diesel also makes exhaust. A lot of it. Which is why you need the snorkel. These are two separate systems. The LOX and LH are strictly for AIP and provide one form of power to the electric motor. The diesel and batteries are the traditional way.
Could someone please explain why subs have such stubby noses? I would imagine that a sharp nose would penetrate the water more effectively - and thus be faster and more fuel efficient. Kinda baffling. All the searches I found just begged the question. (Hopefully that phrase is understood in its correct context).
@jonathan bain Sharp items, when propelled through water, create a lot of friction (It also requires a lot of energy due to boundary layer formation, detachment/separation and then you need to engineer a solution to resolve that issue). This results in the formation of secondary waves, ripples etc which are noisy, in water and thus would give away the location of a sub. Stubby or bulbuous noses are more hydrodynamic and helps in reducing (to some extent) the sonar signature of the sub. I hope this helps - do feel free to check out more cool engineering stuff on streamline flow, laminar flow, boundary layers and cavitation 🤘🏽👍🏽😊
@@deepakramadasan4436 Still, it just feels like an infinite regress of 'whys', because fins are not bulbous..! so if what you say is true, then they should make subs with bulbous fins, see? and a blunt knife cuts worse than a sharp one. I had guessed it had something to do with the pressure and strength of materials breaking more easily if they are thin, but with modern materials the nose could be made sharper than before so i am inclined to disagree from a purely logical perspective ... i often see people repeating illogical reasons simply because they were told this i think it really needs to be tested empirically
@@joeiborowski9763 like i said, i already done that, and the given reasons beg the question or are illogical, as for quora, that is academic dogma for the most part - best to be avoided
@@jonathanbaincosmologyvideo3868 One answer makes sense ,you gotta cram all the sensors up front and the gain you get in speed is not measurable in terms of an advantage over the capability of the sensors being up front.
Brahmos is the Indian version of the Soviet/Russian Yakhont. It is co-produced by India and Russia. It is Intergated Ram Jet. (liquid fuel) 'Integrated' means that the space for rocket booster later turns into liquid ramjet combustion chamebr.
In the 1990s, Russia could not pay back its debt to South Korea. So they sold some technologies for tanks, radars, and IRJ(integrated Ram Jet). South Korea absorbed these technologies and have come out with much-improved version. K2 Main Battle Tanks (MBT) has Russian touch in it. Korean indigenous missile defence (Chunggung and LSAM with indigenous AESA radar) have a Russian touch too. In 2021, South Korea test-fired land-launched anti-ship IRJ supersonic cruise missiles. Koreans call it 'Kyakhont'(Korean Yakhont). Everrything is in veil.
Here in South Korea, some weapons are in veil. Especially those which means something to China. For example, some models Hyunmoo 4 is known to have 2 ton war head with 800 km range. This means it can fly 2000 km with a lighter war head. This range covers every corner of China's sensitive localities. So the exact info about Hyunmoo4 is not opened
I guess they can develop submarine launched 'Kyakhont' without any difficulty if need be. As for supersonic cruise missiles, South Korea seems to be more focused on an air-launched version. Maybe they want for their indigenous fighter(KF-21) something like AARGM-ER (a anti-radar missile) which the US will never sell to South Korea, since this region is too hot.
not many people seem to know of the original P-800 Yakhont compared to the Indian Brahmos, which is ironic consider the latter is a clone of the former
i think the Indian media is to blame for this, as they got a much broader contact with the English-speaking internet world, and India sounds very enthusiastic to promote its anti-ship missile too
so most people will assume a supersonic ramjet anti-ship missile with that silhouette was a Brahmos instead of a Yakhont
here in Vietnam, foreign press (mostly Indian) will occasionally brings up VN as a "potential Brahmos buyer", despite VN having bought & been operating the P-800 Yakhont missile (of the K-300-P coastal batteries) for years now
i think the K-Yakhont might be a direct clone of the P-800 Yakhont too, while its capability might even come close to the domestic Russian 3M55 Oniks version (maximum range ~600-800km)
once the reverse-engineered technology is understood and mastered, the K-Yakhont or the Brahmos could thereotically be tweaked and improved above the downgraded export Yakhont, and even more likely to be crafted from domestically-made parts

Several wrong information is found in the video. (There are more errors but I can't mention them here.)
1. Canto Decoy is not accepted for KSS-3.
2. According to the submarine squadron operation policy of the ROK navy, every "Batch"s has 3 boats, not 2. So No.3 boat is the same as its nameship, Dosan Ahn Changho.

Very nice well summarized description of KSS-3 class submarine.
Absolutely brilliant video! I think you have grown much more comfortable with the format, and it really shows! Really interesting and ground-breaking sub. South Korea have surely and steadily developed an enormous capability in sub design and development, if you consider the small time frame. Really impressive armed forces. Should be an example for everyone else, who can only think in the short-term.
You wanna know something about how the South Koreans fight? Just ask any Vietnam War vet.
I served in ROKN for 6 as a LT.
I was asked to join submarine force but I was smart and declined 😆
Anyways currently serving in USN for past 5 years.
I must say ROKN is a capable navy and with introduction of new submarines I wish my old navy will continue to grow.

Note for the cruise missile:
it is rocket-powered, sort of. The booster (the part spewing fire while going up, but is missing from the level flight picture) is basically a small rocket, most likely solid-fueled. It sent the missile up and away until it reaches cruising speed, and then fall off.
However, for the rest of the way, the missile is either powered by a small turbojet/turbofan. these are jet engines that sip your regular/special mix jet fuel and combine it with oxygen from the air to generate thrust. Not as high thrust, but way longer ranged for the size.
they put h2 storage near missile storage unit lol

So Japan just announced the development of Cruise missile launch capability from their submarines, 3 moths after this video. The moment I read that article I immediately remembered Sutton’s words of a new trend. Amazing insight.
Great summary . Really enjoyed it
While it very likely has a short burning booster rocket motor to propell it to a starting altitude, the Hyunmoo-3, just like the Tomahawk, has a turbofan engine which propells it over the vast majority of the cruise.
The miniature turbojet engine on the Hyunmoo-3 is copied from a Russian design that the South Koreans got from Project Brown Bear, a project where Russia gave South Korea a lot of Soviet military technology as a way to pay off debts.

This was a great video. It also makes me curious about North Korea's fleet and how their submarines are used.
Your channel is fantastic...keep up the good work.🙂
At 9:04 mark you mention Brahmos supersonic missile as a potential armament for KS-III if it's bought by the Indian Navy. You might consider revising based on South Korea's recent testing of its own supersonic missile based off of the Russian Yakhont/Oniks, the same predecessor to Brahmos.
Great video mate, keep it up, looking forward to the next video!
The cruise is powered by turbofan. It's very similar to Tomahawk. Cold launch and rocket booster and turbo. The range is 1500 km. They are working on 3000 km model . .but in a very low profile in order not to push China too hard. . Since the peninsular is too hot, the US has not sold the most destructive missiles such as: Tomahawk, AARGM-ER, LRASM, or JASSM-ER. Anyway, they have been working on missiles like these.

so, regarding the relation between Japan and South Korea, even though there exist, on one hand, historical feud & mild hostility, and on the other hand, a common threat against china & north korea, plus the common ally - the USA,
most of South Korea's drive against Japan's submarine force might just be for national prestige ("we can build a much better submarine than them") rather than any possible confrontation between South Korea & Japan
Well done content. Thank you. Since you asked for a suggestion.

@@mysygisun3335일본인이 질투심에 개소리내고있다
Mr. Sutton, one thing I don't understand is why the Soviet/Russian Typhoon class is constantly referred to as Akula. That is an error. The Akula was a Soviet sskn that was the replacement ,or at least the logical next step for the Alpha class. I have 3 resources which are impeccable. #1. Tom Clancy: Red Storm Rising. #2. 2 close family friends who Nuke sub officers in the US Navy in the 70's to mid 90's. One was the 1st XO assigned to the USS Ohio. He later became a Captain 0-6, of his own Trident Boomer. #3. Last, but not least, one of my best friends from high school who was the senior fire control technician on a LA Class, the Hyman Rickover. All 3 said the Typhoon was never referred to as the Akula, while they were in. Did something change?
There are two Russian subs called Akula
The Pr.941 is called Akula (meaning shark) by the Russians. NATO reporting name is TYPHOON. To see why,, see www.hisutton.com/The%20REAL%20Red%20October%20-%20Typhoon%20SSBN.html
The Pr. 971 is called Shchuka-B (meaning pike) by the Russians. NATO gave it the AKULA designation. This is the one you have heard about.
I tend to use the military/navy norm of using capital letters for NATO code names and lower case for regular names. But it is hard to do always, especially when trying to write for a wider audience
Just subbed . Great content
you keep saying AIP produces hydrogen that they then get rid off but that doesn't make sense. a fuel cell needs both oxygen and hydrogen and combines them to water, that process produces electricity.
Excellent video!!
Just noting that the Japanese subs can fire harpoon anti-ship missiles from their torpedo tubes. I would think that Japan should add VLS to their subs as well, they will need that option.
well they probably need targeting pods on their multirole fighters, some land attack missiles, some method to preemptively strike missile launch sites, oh but wait, they are prohibited from possessing offensive weapons. Their navy is basically the anti submarine support fleet for the seventh fleet.
Their constitutional law avoid those attempt and Abe's administration wanted change the law but failed.
Japan is in a vulnerable position, being threatened by North Korea and China, and possible Russia with nuclear attack. They will not say it, but they cannot rely on the US for nuclear deterrence going forward. That is especially true with the Biden administration in charge- or any future one like it. Yes, Afghanistan points this out more clearly. Japan will need to eventually create their own independent deterrence. Right now, they are trying to keep the US as a close ally no matter the US administration, out of necessity- while trying to pull the US toward their thinking on the threats.
If China does what it threatens in the press, invade Taiwan and simultaneously does a limited nuclear strike on Japan, what happens. Biden does diplomacy to prevent escalation to the US is most likely- capitulation, treaties and agreements ignored. We already see that they are good at ignoring US laws. Taiwan and Japan will be abandoned. The only defense Japan really has now is their Aegis (BMD) destroyers, and possibly drawing in the US, from the fallout on US bases in Japan. Regardless of laws, from a military perspective they need their own deterrence. China is probably calculating this scenario as well, making Japan’s stance on nuclear weapons in-affect destabilizing. The VLS on their Subs would be the best step forward for a survivable counter strike ability. Even having a conventional strike ability with SLBMs or cruise missiles on their subs sets the stage and provides some deterrence.
The new PM of Japan, Kishida, is already pushing for strike weapons. They could easily modify their anti-ship missiles as land strike missiles (the ASM-3A, or the in-development missiles: Type 12/Type 17 increased range missiles, and the hypersonic ones they are working on as well). The latest version of the US SM-6 missile will also have a surface strike ability, and most likely added to their destroyers. Really, what you consider to be an offense weapon can be argued to be a deterrent and thus defensive, the extreme example is the MAD doctrine we have all been living under.
@@douglasstansfield3957 Unfortunately, Prime Minister Kishida was cautious about deploying nuclear submarines.
Also, deploying weapons capable of attacking the ground is probably impossible due to the obstruction of the Japanese media and anarchist opposition, which are hostile to the government. Also, the majority of Japanese people are afraid to return to militarism, so there is a strong sense of refusal to excessively strengthen their armaments.
Furthermore, it is necessary to make major changes to Article 9 of the Constitution in order to acquire the ability to attack enemy bases, which is quite difficult.
Coastal areas there would appear to be congested with subs.
Please do a review on the iranian fateh class submarine Mr. Sutton
Some guess work on the new Aussie sub would be nice.
I would like a video on how do submarines navigate while under water.
I know the case of a US sub that ran into an underwater mountain at 25 knots (I've seen pictures of what the sub looked like afterwards). One of the sailors, thrown into a door, died.
I would like a short description of Low Alloy High Strength (I think this is what it's called) and why it was used. It worked well for that sub.
There was a VERY recent development of a quantum IMU (inertial measurement unit) which is just an accelerometer so precise it can actually give you your accurate position if you know the initial position so presumably no drift. It was developed specifically for naval use when there is no access to GPS signals and to me that screams submarine.
It seemed pretty huge though so I don't know about retrofitting existing subs with it.
@@MrRolnicek Thank you, Roinicek, but my question was specifically for the subs without Space Station equipment onboard. The regular subs of today, which patrol submerged for months, without seeing sky OR the bottom relief. How did they know where they are when submerged? How did they know where they were heading?
@@SerbanOprescu I get it but I don't know much about that so all I could contribute is the near future.
I believe the current ones use gravity measurements as part of their navigational toolkit but that's about all I can tell you.
In the KSS design, diesel charges the batteries. But what do batteries provide which LOX and H do not?
It's very interesting. By the way, do you think the Korean Navy will operate supersonic cruise missiles and cruise missiles in addition to SLBMs in the VLS of KSS-III class submarines?
I guess would be no. If anything they'll use as many of the slots for SLBMs as possible so maybe no cruise missiles at all.
@@HISuttonCovertShores Thank you for your answer. But the reason I asked you that question is because I read an article that you contributed to the Navy News. In the drawing, it is described as if a supersonic cruise missile is operated in the VLS of Dosan An Changho. By any chance, did you take into account the Indian project?
And you seem to think positively about AIP submarine. However, at the condition of the highest speed under water, the maximum cruising time is still significantly lower than that of nuclear-powered submarine. Nevertheless, can AIP submarines be viewed as a game changer?
Sorry, are you referring to the Brahmos missile which is illustrated? There are three missiles in my illustration, talk:
Hyunmoo-4-4 - SLBM, I would think the main weapon going forward
Hyunmoo-3C - SLCM, like Tomahawk. Low-supersonic - I do have an error/oversight in not mentioning the jet phase but cannot edit the video
Brahmos - mentioned in context of P75I competition
Re AIP, to clarify, I think that it is a game-changer to combine modern AIP with a VLS, and more so because of the small SLBMs. AIP has both pros and cons over nuclear. This video discusses pros and cons of AIP. th-cam.com/video/c2QS_aEsVuw/w-d-xo.html
This video was made before the AUKUS announcement. I haven't changed my view on the significance of the KSS-III
Hope that this helps.
@@HISuttonCovertShores Thanks a lot!
Supersonic cruise missiles will be launched with torpedo tubes.
The Korean version of Brahmos has been specially miniaturized for torpedo tube launches.
If Korea happens to develop nuclear weapons they’ve got a second strike platform ready to go. That they can make use of it conventionally in the interim gives them deniability and export markets. Well done.
That's the master plan Neil. These are a meticulous and rational people.

Take note,North Korea does have SLBM (new,nuclear capable),they have already tested these successfully in 2021.
Way lower on the sophistication scale, though.
I dont expect to see Brahmos in S.K service when they just tested there own hypersonic anti ship missile they will adapt that to be sub launched aswell and interestingly it looks quite similar to Brahms or oniks anti ship missiles.
No those were supersonic not hypersonic. They look similar because the technology was originally from Russia
It's gonna be smaller than Brahmos and longer range but not as much as Brahmos-M upgrade distance range.
The Brahmos was put on there for the benefit of the Indians, who are also looking for an API sub with VLS. Export market, which the Koreans are keen on.
@@miraphycs7377 super long distance missiles are a bit tricky since they may not hit their intended target and hit an oil tanker or a commercial cargo ship instead. Shipborne radar on missiles are not particularly choosey.
whats the diffence in putting the hydroplanes on the front of the hull vs on the sail?
Have to be able to retract the forward planes into the hull for docking operations. Added additional complexity and weight.
Polish MoD Mr. Błaszczak announced beginning of program ORKA - purchase of Polish Navy submarines.
KSS submarines definitely will be in scope of interest.
The SK facebook page said there will also be a flight III
Do the missile launch tubes after launch require repair?
OF course not , they implode under sea water pressure and the submarine sinks instantly !! FFKs sake. TE Fidler
@@F_Tim1961 The Russian original fielded missile tubes on subs required repair before reloading. Pretty sure it took the US some time to get the tube engineering right so the pressure of rocket nozzle blast wouldn't mess things up.

Mr. Sutton, can you also cover the significance of lithium ion battery with regards to conventional submarine? Thank you!
Hi, towards the end of this video I touch on that th-cam.com/video/c2QS_aEsVuw/w-d-xo.html
@@HISuttonCovertShores I watched that but it didn't cover the game changing aspect of it. JMSDF (Japanese) claims 100 minute recharge time at snorkel depth every 10 days, which equates to having to use diesel engine less than 1% of time, without even taking into account AIP usage.
They also claim ability to cruise at 20 knots underwater for sustained period, using only lithium ion battery.
Also, detailed discussion of Stirling (heat) engine vs. fuel cell AIP would have being informative.
@@mrteacher1315 wondering/ hoping you can provide a cite for what you say is the game changing 100 minute recharge time @ snorkel depth every 10 days for their LIBs. If true that does seem game changing and would seem to obviate the need for an AIP system. Thx in advance ..
@@brodieboy3 I believe I read it in an analysis by JMSDF and/or defense ministry study when they decided to go 100% lithium-ion battery instead of AIP+lithium-ion battery after they did feasiblity studies. This was several years ago.
Quick search yielded an article in The National Interest titled "To Counter China, The Japanese Navy Is Investing In Submarines."
Then in the article, you'll see the following sentence: "Japan has already studied optimizing the snorkel for the diesel engines on the Soryu class. Though LIBs are faster charging, given the SS-29’s huge planned battery capacity, the improved snorkel may be necessary to avoid taking longer than the claimed 100-minute charging time for the LIB-equipped Soryu."
"The SS-29 class will be built around the extraordinary battery capacity offered by lithium ion batteries (LIB). At the blog Submarine Matters, analyst Peter Coates speculates the new design might boast up to ten days cruising submerged."
It's possible that 10 days might not be correct for converted Soryu. There are some calculations showing 6-7 days instead.
I think one thing that has to be said is the North Korean fleet is very old but the crews or modifications from all available evidence amazingly good, especially taking into account that during a South Korean Anti Submarine Warefare excerise, so everything is being closely monitored a North Korean sub just decides to go into the middle of the pack sinks a South Korean Corvette leaves and isn't detected once.
Can you go back to no ads for this? I like to listen to these before bed and the ads really disturb my peaceful absorbing of open source sub intel. I have to switch back to drach when the ads come on.
How many subs are equipped with metalstorm technology????
Can you make a video about the Chang Bogo class submarine?
Canada apparently has some interest in this type. I am curious as of to what batch.
Cruise missile is variant of en.wikipedia.org/wiki/Hyunmoo-3 . I think Russians at least conceptualized similar layout for Amur Class, so did Swedish Kockums for A-26. In any case, hull diameter for non-nuclear sub will limit size thus range-payload of the missile and cruise missiles are far less conspicuous. Especially ballistic missile will be detected early over flat sea.
My guess is SK need the fast delivery munitions for its submarines lurking outside the NK coast to neutralize NK nuke SLBM launchers before the launch. Cruise missiles would be too slow for it. I doubt NK has capability to hunt subs outside its litoral water.
How do we know so much about military hardware? I'd have thought much of this would be state secrets.
Maybe you can do a video just on the type of sonar used ?
2:20
A commonly overlooked fact.
always interesting and nicely off-script.
There's no Brahmos.
Talk about Yakhont.
Another brother of Yakhont and Brahmos family. Got smaller and faster and longer range from older generation but Russian/Indian technicians will upgrade the missile with better spec. then this.
Australia develop there own independent tiles to reduce magnetic footprint
their
france dose not have Anechoic tile?
Not first with vertical launch the Swedish replacement subs have that as a variant as well.
The VLS in the A-26 is only an offering, no customers currently and no boats built.
The first KSS-III was laid down in 2016 (and would have been designed years before). The A-26 models with VLS were first shared in 2017(?)
The late LA class subs have VLS as well for tomahawks. . But not for SLBM.
KSS-III are best Subs for P75-I program
Look so similar to german TKMS submarines. Think they learned a lot from them
Listen game changer really! You need to study geopolitical scenarios one sub no matter how good it is will not be a game changer!!
ROK Navy 👍
wonder, how a bigger KSS-III class or a larger Type 212B & Type 216 class of SSNs would fare against it's rivals . . . let's say, a fleet of 10 brand new KSS III class 5,683 ton (6,234 ton loaded) stealth guided missile fast attack submarine powered by iFuelCell™ FC3 AIP-HYBRId® system . . . armed with 8-cell SYLVER A50 VLS built into the forward bow section of the submarine hull . . .
SYLVER is not designed for use on submarines.
Thank you.
9:40 what is this AIP you keep referring to?
Air
Independent
Propulsion
AIP can operate for extended periods without needing to snorkel.
Any reason why the hydrogen is outside the hull?
Remember the Hindenburg?
The Swedish Blekinge has the vertical launch tubes as an option as well as 3 different sizes
Hi. fantastic video however. I just have one problem that I would like you to explain.. The question is why do you not seem to differentiate between North Korea and South Korea until you are half-way through your lecture, are you trying to maintain that they are the same country!!! Sorry no offenses meant, just curious about your preference?
They obtained a license from TKMS so it very likely is based on the 214. it even looks like it and uses almost identical PEM fuel cells, same sonar, sensors, etc.
Even the change to lithium ion is in line with U212CD.
Nope. They license built 209 and 214 then moved onto bigger and better. Only sub with AIP and lithium ion batteries are made in Japan and Korea. One of main reason why Canada is considering subs from these 2 countries, German subs too small and underwater time not long enough.
@@leedavid408 the U212CD also uses lithium iron batteries. And btw. The U216 that was offered to Australia was even bigger (90m and 4000t). That Germany uses the 212is small is because it has to operate in the Baltic Sea, which is basically a lake. Size is not the problem. It‘s easy to build a big sub.
212cd to be delivered in 2029 & 216 a concept design Australia rejected. In other words non existent German subs with state of art AIP and lithium ion batteries which korea and Japan are operating/marketing presently.
@@leedavid408 it says in the Wikipedia article about the KSS-III (with reference) that it is based on the U214. The U212/214 was the first using PEM fuel cells.
I give you that Japan was first to introduce lithium-ion batteries on subs in 2023. However, the U212A being retrofitted as they have been testing it for many years. Hardly news then.
Still your case about size is irrelevant as there is no technology behind making subs bigger. An whether they are 80m or 90m is not a leap in innovation.
The U212/214/218 have all been sold extensively. So that Canada is considering Korean and Japanese subs is normal. And I am sure they are good. But for the same reason India is currently considering the TKMS subs.
To be honest switching from fuel cell to lithium ion batteries will be a challenge for Germany
2020 top lithium ion battery manufacturers market share

2. CATL - 25% (China)

I believe SAAB-Kockums offer a VLS module option for their oceanic (long) variant Blekinge (A26) class.
Yeah - Saab offers lots of things in their PR brohures .. but they've not even built a single new sub since taking over Kochums in 2014. The A26 just got delayed for the 3rd time - this time by an additional 3 years with the 1st boat (which of course won't have a vls module) is now scheduled for 2027 .. after originally being promised in 2019, then 2022, then 2024 and now 2027 .. will it ever be delivered?
Another great.
Interesting that they choose lithium ion batteries over a technology such as LiFePO4.
I hope this type of sub becomes new norm so small countries can afford some retaliative punch.
This submarine is the best submarine for any nation who has access to nukes but doesn't have them. Atm.. Going thing missing is Nuclear powered which is needed for Canada which is looking for a Multirole intelligence special forces multiple cruise missile cells torpedos ballistic missiles all nuclear capable and double hull nuclear powered for Arctic operations and long range
The Hyunmoo-4 is essentially a Russian Iskander missile. That Brahmos looking thing is essentially a Russian Oniks missile, but made smaller so it can be fired through a torpedo tube.
correction, based on Islander design but not entirely similar, just that design is. Rocket system is very similar but it's system and electronics are very different.
interesting thanks
While it's perfectly natural that ROK dislikes Japan, I can't see how they've actually thought of them as a *threat* in the past 75 years (especially with the USN right there).
75 years after 50 years of forced colonization and occupation by japan when it illegally annexed the country, murdered the last surviving royal family member, outlawed the korean language and korean names, and then confiscated private land to be owned by imperial army and emperor, yea that one. I wonder how they can see japan as a threat? your right, totally kawaii people.
@@murderofcrows2179 did you purposefully ignore "especially with *the USN right there",* or just stop reading half-way through a very short comment?
Probably not with both nations ally with US and as long as US dominance in western Pacific, but you just can't guarantee 10 to 20 yrs in the future with resurrgent China.
the presence of the united states navy (7th fleet) you expect to be some form of reassurance. North Korea invaded south korea when the US was the official protectorate of the country, and when it had ground forced in the country. The US had its soldiers in the country during the CIA sanctioned military dictatorship. Democracy was not provided by US soldiers, but by korean citizens and students protesting daily and being beaten and disappeared for over thirty years while being protected by the US and when several divisions of US army were present. same situation when the SK president was assisinated and a second military dictatorship installed, after getting green light from US intelligence and diplomats. So your thinking isn't shared with any koreans on earth.
Not to mention the North testing and becoming a nuclear state during America's sole super power hegemony over south korea.
the lifepo batteries is what caused fire in new Russian sub they should use lto batteries
I really doubt it (SK submarine ) has LOX as an oxidant for the F cell, as opposed to highly compressed oxygen as per what the GErman type 212 uses. LOX means you Have to use up the Lox from the get go... if you don't it will boil off and it will have to be released or the pressure vessel will burst. This automatically means a trail of oxygen bubbles in the sea which ain't smart as a stealth weapon . Moreover you have to warm it up before it goes to the fuel cell This will require electric power or reheat from the fuel cell . It also makes Oxygen refuelling at sea next to impossible (as opposed to compressed oxygen refuelling ) .
TE Fidler
Agreed but the French seem to differ there variant utilise LOX & reformulated Diesel for hydrogen for their fuel cells.
Type 212A uses LOX in insulated tanks above the pressure hull (underneath the GRP fairing). The LOX evaporator runs on waste heat provided by the fuel cell reaction.
Lets use hypergloic reaction, as in high test hydrogen peroxide & doped Kerosene/Diesel to drive a pair of 10 Mwatt class turbines. Compact, refuel at sea possible, reliable, simple, robust & high power to weight ratio of machinery, fast recharge for solid state li ion batteries. Power levels approaching not quite SSN flank speed but sufficent for long range (1000+ nautical miles) relatively fast 20+ kts submerged strategic deployments or very fast recharge 30 to 40 minutes or less.
@@kevinyaucheekin1319 That's efficient, but then you get SSN noise levels without SSN capabilities. For SSK, especially littoral types, fuel cells are absolutely silent; tie to Lithium Polymer batteries for sprint speed and you have a sonic black hole that can get up and move if need be...
Neat.
Can you do a video on Canadian submarines then and now.
I lived in So. Korea for a year. I can tell you that they absolutely hate Japanese there. I recall being in a large restaurant in Seoul when everyone in the building stopped talking at once. My friends and I asked the waiter what happened so suddenly. He responded that a Japanese woman walked in and Koreans hate the Japanese because of the unspeakable things they did in WW-II when they held the country hostage.
As I can say as S.Korean, S.Korean doesn't hate Japanese visitor, We just despise Japanese government and their Arrogance without truly apologize although they slaughtered so many Korean. They always interrupted to unite Korean.
Through History. to prevent same 18 century situation, S.Korean shall prepare against Japanese invasion when will be out of control from US someday.
완전한 거짓말입니다. 2019년에 3백만의 일본인이 한국을 방문했습니다. 한국인은 일본 제국주의와 평범한 일본인을 구별할 줄 압니다.
That is absolutely absurd. There are many japanese living in korea. Its not rare to see them talking on the street or subway.
unscripted is best for this type of video
although a rather on par with on paper VS than in reality
if france, uk and spain helped build it or at least part of it, can you technically say it is indiginous?
The ECA group and Babcocks have certainly provided assistance as the story on this sub mentions. RoK can take great pride in what has been designed and built. Building 27 of these subs in such a short space of time shows a fantastic ship building ability for such a small nation.
@@stevepirie8130 huh where did they say they will build 27?
In their news release and on some of the videos about it over the whole lifespan of the type.
@김요한이야기 a lot of people may not realise S Korea has a massive and successful shipbuilding ability for both civil and military use.
Is Saab gripen Swedish if France, uk, Germany, Israel, US help the Swedes to build it?
S Korea is already developing micro reactor for KSS3 to stop N Korean SLBM 24/7 duties.
I truely believe that I know how make Li-on batteries safe for submarine use. This is to prove that I knew how to make it when writing this comment.
brahmos isn't an indian missile. it's a russian missile.
It's like same missile but Rissian version is called Yakhont and Indian version is called Brahmos.
It is Russian but the buyer gets to rebadge it.
MAKE IN INDIAAAAAAAAAA!!!!!!.... 🤣

AIP allows the disease engines to run underwater, which in turn produces electricity 4 batteries & thus increases submerged range w/o surfacing or snorkeling.(can't have combustion w.o air)
That's the snorkel system. The AIP is fuel cell. A reaction of LOX and LH thru a membrane to produce water and power. The process can be reversed by using the diesels to produce power to break up water.
@NorthForkFisherman I said "w/o (without) surfacing or snorkeling". But yes, I'm aware but thankyou anyways good sir. Basically a means for power, propulsion, & crew needs(air, water, electricity) w.o using diesel engine(or supplementing)
@@jdogdarkness And a diesel also makes exhaust. A lot of it. Which is why you need the snorkel. These are two separate systems. The LOX and LH are strictly for AIP and provide one form of power to the electric motor. The diesel and batteries are the traditional way.
i wonder why not NiMH those are nice batteries too still much better than lead acid and dont burn as lithium ones either
1:49 F85 jets? They fly the WW2 Goblin parasite plane?
Could someone please explain why subs have such stubby noses? I would imagine that a sharp nose would penetrate the water more effectively - and thus be faster and more fuel efficient. Kinda baffling. All the searches I found just begged the question. (Hopefully that phrase is understood in its correct context).
@jonathan bain Sharp items, when propelled through water, create a lot of friction (It also requires a lot of energy due to boundary layer formation, detachment/separation and then you need to engineer a solution to resolve that issue).
This results in the formation of secondary waves, ripples etc which are noisy, in water and thus would give away the location of a sub. Stubby or bulbuous noses are more hydrodynamic and helps in reducing (to some extent) the sonar signature of the sub.
I hope this helps - do feel free to check out more cool engineering stuff on streamline flow, laminar flow, boundary layers and cavitation 🤘🏽👍🏽😊
@@deepakramadasan4436 Still, it just feels like an infinite regress of 'whys', because fins are not bulbous..!
so if what you say is true, then they should make subs with bulbous fins, see?
and a blunt knife cuts worse than a sharp one.
I had guessed it had something to do with the pressure and strength of materials breaking more easily if they are thin, but with modern materials the nose could be made sharper than before
so i am inclined to disagree from a purely logical perspective ... i often see people repeating illogical reasons simply because they were told this
i think it really needs to be tested empirically
Just google: Why subs have such stubby noses quora.
TH-cam doesn't let me leave links.
@@joeiborowski9763 like i said, i already done that, and the given reasons beg the question or are illogical, as for quora, that is academic dogma for the most part - best to be avoided
@@jonathanbaincosmologyvideo3868
One answer makes sense ,you gotta cram all the sensors up front and the gain you get in speed is not measurable in terms of an advantage over the capability of the sensors being up front.
