They actually already have drones that mimick the signature of the parent submarine. They're called MOSS for Mobile Submarine Simulator. They can be launched from the submarine's torpedo tubes and it can either go off and do it's own pre-programmed thing or it can be controlled from the sub through a wire.
@@killman369547 So you're bald as well then.
Did you look down the back of your sofa? I sometimes lose things there ,maybe your long lost locks are there too!
@@Wardads1 No, not me. I've got a fine head of hair for a 90 year old.
MAD devices are not exactly new. They have been part of ASW operations for a very long time.
As a retired USN sonar tech who served during the 80's and 90's I can honestly say that Anti-Submarine Warfare is a science of vague assumptions based upon debatable figures taken from inconclusive experiments performed with instruments of problematical accuracy by persons of doubtful reliability and questionable mentality.
Bruce, STG for STS?
So basically, idiots guesstimating? 😂 frightening.
Sounds like much of the military in general 🤣
Dang during the 80s? Were you hunting Russian subs all over the ocean depths? During the Cold War would be a spooky time to be a submariner
80s and 90s? Might as well have been the stone age... Clearly technology has advanced a bit since then?
US subs accounted for 30% of Japanese ships sunk in WW2........imagine what that number would have been if the Bureau of Ordinance had admitted the glaring problems with the Mk 14 torpedo, and fixed them.
Probably closer to the percentage from the Odyssey Dawn campaign in 2011, where a SINGLE US sub accounted for 75% or so (napkin math) of sea based missiles launched. 😂
excellent comment!! the original torpedoes bounced off the target.
US Navy Submarine Service accounted for about 55% of all Japanese tonnage sunk in the war. This was done by a branch of the Navy that accounted for about 1.6% of the Navy's wartime complement.
The Japanese lost 1,178 Merchant Ships sunk for a tonnage total of 5,053,491 tons. The Naval losses were 214 ships and submarines totaling 577,626 tons. A staggering five million, six hundred thirty one thousand, one hundred seventeen tons, (5,631,117 tons), 1,392 ships.
Japan ended the war with a bare 12% of her merchant fleet intact but not fuel at hand to run more than a few of them.
U Boats caused a hell of a problem too.
@@neth77 That is correct. At wars end 783 of them (to best count) resided on the ocean bottom. Allied ASW got better.
Sweden having insane engineering seems to be a running theme in these shows.
They remained neutral between NATO and Russia for decades, and they required making effective technologies to keep up with the others. They also control key waterways so needed to really be on point. Sweden Joining NATO is really a huge diplomatic, strategic, and capability win for NATO. If they get involved in a Gen 6 airplane, they could give Lockheed a run for their money on capability.

@@randys2358 Lol, yes, because the US Navy and several other countries use TH-cam when searching for new planes and subs ... Money well spent SAAB 😂🤦♂
@@BrodieB762 you forgot about the dynamite
The statement that subs wouldn't utilize active SONAR during combat situations is a common misunderstanding. When they are on ISR missions they are not allowed to be detected by anything, they won't use active but during combat situations there are plenty of valid uses of active sonar to include:
- shadowing another submarine outside of their weapon's range
- refinement of bearing and range just prior to the moment of weapon release (i love this one because it results in "hey is that active ? ..... oh shit launch transient. torpedo in the water.) on the targeted submarine.
- flushing the enemy towards another unit in passive search
There have been some rumors that for the next generation of torpedoes, that ping will be an intermediate sub getting an updated position to relay to a weapon already on the way from a launch platform over 100 NM away.
Nuclear didn't make the sub quieter, it made it so they needed to return to port less frequently and didn't have to surface to run fossil generators to recharge batteries.
Nuclear also meant they had more power to spare for energy intensive processes like electrolysis and whatnot which further extended the time they can stay submerged.
The (arguably) most silent sub is a battery powered one, it's just not very capable far from its home port.
And Sweden was able to sneak up on an US carrier fleet during a joint exercise, take a picture of it (which in effect was like sinking it) and escaping without the US ever knowing they were even there. They practically shat their pants when Sweden later showed them that Sweden had "sunk" their carrier and effectively proven that the US has a major weakness.
An Australian sub also 'sunk' an American carrier, diesel electrics are super stealthy.
Nuclear is FAR quieter than a conventional diesel electric. All subs are electric, by the way. Every single sub is driven my an electric motor. How that electric motor is supplied power differentiates. Lololol…..This electric sub you speak of….lolololol……do they charge it up like a Tesla? Seriously think about what you wrote and a wave of warm shame should envelop you when you realize you had no idea what you’re taking about. You kiss the simplest of concepts on submarine propulsion. Electric subs? They don’t use mechanical power straight to the shaft- THAT would be noisy beyond measure. That’s why since WW1, over 100 years ago, the final drive, or the thing that turned the actual shaft and propellor, was an electric motor which could be finely controlled to minimize noise and maximize efficiency.
You are incorrect is something I would have to say quite often about your post. Just….wow.
Air Independent Propulsion (AIP) is a hybrid Sterling Engine/Electric propulsion unit. It has been used in the Gotland Class since 1995, and it, The Gotland, is the sub you describe sinking the US Carrier in the war games in 2005. With AIP, the duration (underwater or topside or completely underwater or completely topside or any combination of the two) is not given in days, but weeks. That’s weeks. It is limited by the amount of liquid O2 carried on board. The maximum a conventional diesel electric sub could stay under in an emergency situation to avoid enemies is days, at the most. That AIP sub that won in the war game in 2005 against our carrier? Apparently we liked practicing against them or we sucked so bad they realized drastic measures were needed. We then leased it for a year, completely manned by Swedes under a Swede flag to brush up our Navy against these little devilish classed subs (AIP). Being how it’s all classified I assume it went VERY badly for our Navy because you don’t lease a foreign sub and crew to be your practice partner for a year if you’re good at finding them. Apparently it was so bad at whoopin’ our asses we leased it for an immediate second year, lol. Supposedly new equipment and training has helped. Unless you serve presently or were top brass, you don’t and won’t know for a very long time. Oh, and non-nuclear or diesel electric subs not being very efficient or effective away from home port like you claim? The Germans using a CONVENTIONAL diesel electric (Type 206) (noisy when it generates power, at least noisy on the submarine scale) ‘sank’ the USS Enterprise in the Caribbean….in the year 2000. The story is a good one and documented. It’s in it’s Wikipedia page. I am including the links so you can read up on them since you skimmed some headlines and copy/pasted them here, and then some incorrect assumptions tossed alongside an outright lie. Why don’t you go to the wiki pages and see if you don’t find a section that gives an introduction primer. In there, it should have this word called “range.” Look at the number beside it. That’s how far it can and still make it back to the point it started from with 10% fuel reserves. And you know the Germans were in the Gulf of Mexico in WW2? Not to mention all over the North Atlantic. Propulsion type does not tie these boats to home ports or any port for that matter, excluding specialized overhauls where the sub is usually cut open and specialized people and equipment are needed to do so.

@@BigDaddy-yp4mi Nuclear submarines are noisier than conventional powered submarines. Nuclear submarines need to have pumps going constantly to keep the reactor cool etc. Diesel submarines are not as noisy as you think as they only have to go to periscope depth to recharge as they have a snorkel and it only takes a short while to charge the batteries. Also a conventional powered submarine can stay fully submerged for up to a week.
The biggest problem with diesel electric submarines compared to nuclear submarines is the transition time it takes to get to their patrol zone. That is why the RAN are seeking nuclear powered submarines so their submarines will be able to stay in their patrol zone longer than what they can achieve with their current submarines.
@@tomnewham1269 It's all about the recharging. The Swedish Gotland class doesn't use conventional diesel electric but rather a sterling engine using liquid oxygen for the combustion of whatever fuel they have. This means they technically don't need to surface to snorkel depth to recharge. It's also quieter than normal diesel generators. I think I remember them being able to cruise for about a month without breaking the surface. This is one reason they were able to creep up on the US Carrier without being detected. They aren't the fastest or can spend as long time submerged as the nuclear subs, but they are comparatively very quiet and economically a lot cheaper than going nuclear.
Now these subs have very different design goals. The nuclear subs are huge and can launch nuclear attacks if needed while small subs like the Gotland class are really hunters and almost only work with torpedoes. That's s huge difference. Still a silent sniper have the chance of not getting caught by support ships. For a sub being caught on sensors is an almost certain death. Depth charges put enormous stress on the hulls, and that skin is the only thing keeping the personell alive. The deeper you dive the nastier the external pressure will be, and the charges will cause more stress on the life keeping skin.
Submersibles really are overpowered. They can't run faster than the surface ships that might be hunting them. The hull is rather fragile, and the depth charges don't have to hit directly to cause serious damage. Just get the detonation close enough and the hull will crumple.
@@raptor1672 fun fact the current australian subs were built by saab

I believe it was a SAAB submarine that evaded all US detection in a war game and "sunk" a US Carrier. That prompted the US to lease the submarine and study how to detect it, and also how to build one.
So usa... basically stole the swede sub design?
It is a Gotland class sub with sterling engines. It sunk USS Ronald Reagan with a substensial ammount of diverse following ships aswell. All in simulation war games. The US as you say, rented the sub with personal in 2012 and im pretty sure they still looking for it 😂😂
After searching unsuccessfully for a year and being photographed from underneath a carrier. The US decided to rent the Gotland for another year and still failed to fint it.
@@Tehinke Interesting. Is this an update to the original info-bit I posted? Or just a snarky joke? If former, thanks for info.
Funny thing about the rubber tiles on the outside of the subs.
They have been found to have circles cut out of them after long times at sea.
The culprit? Cookie cutter sharks.
I was stationed on a sub tender back in the '80s when anechoic coating was brand new. They hadn't figure out the right glue. The boat had it (I don't recall her name) would come back with pieces missing or flopping. LOL
Apparently they've figured it out. 😂
The Russians would bolt the tiles on. The bolt holes were then filled with a plug that would sometimes fall out. Ask me how I know. I was the site manager for the Russian sub in Providence RI back before it sank in 2006. I was long gone by then. Russian steel used to build that thing was crap!
@@webbtrekker534 The last time conventional Russian forces were a threat was the end of WWII. Without their nukes, Finland could invade and conquered them within a month.

Swedish design are coastal attack/spy subs
France also got insanely quiet subs
And most stealthy subs are ones with AIP systems, not nuke ones !
Nuke cores pumps are loud AF !
And now subs are moving Lithium batteries, France is proposing version that could stays under water for 89days and able to great speed if needed
I have veen searching for an answer to how America plans to deal with battery operated subs if need be. There are no answers available. That doesn't mean there are no answers.
Only the D.C. steam turbine, the "Core Reactor pumps are quiet" that's why ,Batteries are still used kept charged to use as back-up, in "Run-silent" mode. I repaired, 688 class subs.
Stirling engines. They work on heat differential alone. Also everything dampened from machinery to coffee machines is on shock absorbers that dissipate vibrations and the entire thing is insulated like a music studio. And of course the big secret in any quiet submarine is the propeller geometry. How to avoid cavitation but still get a decent RPM to move forward. Back in the day RMS Mauretania shook so violently from her four propellers the aft quarters where uninhabitable and she had to go back into drydock to be reinforced. They didn't understand why the smooth turbines would vibrate so much but it wasn't the turbines, it was the propellers causing violent cavitation, turning the water into steam. They did it by trial and error swapping around props. A big controversy was if Titanic had a 4 bladed or triple bladed central propeller. It was always believed to be 4 bladed as with the older sister RMS Olympic and as to the design but they were constantly swapping props and trying stuff, including putting a 3 bladed propeller in the center on Titanic. She sank, do they never got the results from the test. Despite racing across the glassy sea at 22 knots with the last boiler room still offline, later tests with Olympic showed the 3 bladed propeller was a detriment and so she went back to 4 blades in the center and 3 on either side.
On the wreck the center prop is deep in mud so only when documents and orders for the propeller were found a few years back in an old Harland & Wolf archive was it proven.
The famous image always shown of Titanic in drydock with the 4 bladed center screw is actually Olympic. Many photos of Titanic are Olympic. They were so similar Harland & Wolff didn't bother to photograph Titanic in as much detail as Olympic. Except the exterior where the closed up A deck promenade on Titanic makes them easily distinguishable. This is where the popular Café Parisienne was expanded and forward the two millionaires suites with their private enclosed promenade (Rose's quarters...) on Olympic those where on the fully enclosed B deck. Also Titanic had carpeting in the first class dining room unlike shown in the movie and unlike Olympic.
@@user-lv7ph7hs7l i got really excited when I saw your post. A long one from someone knowledgeable on subs? Woo hoo lots to learn!

@12:20, so we're finally, after all these years, are serioulsy looking at being within grasp of getting freaking sharks with freaking lasers on their freaking heads?
We use Dolphins. The Ruskies use Belugas. Ever seen a beluga loaded on vodka?
10:14 Magnetic anomaly detectors (MAD) are not new technology or a recent innovation. They were used for ASW starting in WWII. They are still a useful short range detection system against subs.
Didn't realise they were quiite that old. My understanding was the '80s?
Which is why every sub goes through degaussing on a regular basis, to minimize the boat's net magnetic field.
As long as you’re not chasing a titanium or stainless steel hull…
@@komradebob stainless is still detectable.
@@_starfiend MAD was WW2. Nimrods had MAD booms in the 1970's

In 2001, during the exercise JTFEX 01-2 in the Caribbean Sea, the German U24 of the conventional 206 diesel-electric class "sank" the carrier Enterprise by firing flares and taking a photograph through its periscope.
The Type 212A uses hydrogen fuel cells and is so extremly quite!
The system is also said to be vibration-free and virtually undetectable.
A Royal Australian Navy Collin's class submarine also sank a US carrier during a Rimpac execrise. A Gotland class submarine has done a similar thing too so sorry to burst your bubble but it is nothing new that a conventional submarine can sink a US Navy capital ship.
@@tomnewham1269French nuclear subs have also done it
As did a Dutch Walrus class diesel electric sub (it 'sank' half the fleet apparently).
LOL While everything you said was true. There were limitations placed on the US fleet during the exercise In fact the US nearly always gives the US fleet a disadvantage so as to gain more data.
Sorry to burst your bubble about it all but fact is. The US have been downgrading their assets in an exercise for performance evaluations and assessments for over 40 years.
quiet not quite
(International Spelling Police)
Anechoic tiles do not do a lot for internal noise. However their hardness is tuned to dissipate active sonar pings. That's why UK subs operate not only on a range of frequencies but also sweep up and sweep down. It's not always the sub that pings either. EG there are sonobuoys that are pre programmed with a ping pattern that can be released. That way the bow sonar can be used without trailing microphones which are noisy due to causing drag. Also below a classified speed some subs can pass within 2 meters of the seabed microphones. There is a huge amount of research on increasing that speed. I can't say what it is as I think it is covered by a 50 year D notice (Do not disclose notice).
Give me a ping, Vasily. One ping only.
Nuclear subs are loud. Modern AIP subs buy Germany and the Scandinavia countries are much quieter. Slower and less range sure, but silent. Nuke boats can never turn off loud coolant pumps keeping the reactor from melting down.
Are you sure about that????
Neville Shute: On The Beach … great story!
Last Chinese sub I heard was so loud you almost couldn't keep the headphones on in the sonar shack... while they were in port on the other side of 2 shipping lanes.
it’s folly to underestimate your adversaries.
China is experimenting with internal rim drive jet propulsion and magneto hydrodynamic drives.
Their latest submarines have latest tech such as active noise cancelling and indirect electric drives.
Even their older subs have improved rubber tiles and lithium batteries replacing lead acid batteries.

i always love the submarine vids! im guessing other people do too!! thanks and keep it up!
Somehow forgot to mention that one reason the Gotland class famously "took out" US submarines undetected, (during exercise) was its use of sterling-engine air independent propulsion technology making it very quiet (a world first at that time)
The Swedish Gotland-class submarines use a Sterling air independent propulsion system (AIP). A Sterling engine electricity generator is employed to recharche the batteries. Sterling engines are much quieter than internal combustion engines.
When I was in the Navy I was stationed on a Fast Frigate who primarily function was sub hunting so we had both types on board, a sonar dome on the bow and a towed array aft. We also had a helicopter crew on board during operations that had sub hunting capability and we were very good at finding lol.
Nice to see that the background music is at normal levels.
Wowza, that wasnt a long wait for the next Megaprojects! 👏
Exellent
Magnetic anomaly detection has been around for years. The old p-3 Orion had a MAD detector in the boom at the rear of the plane. Kind of a big error for megaprojects.
The Canadian Aurora ASW aircraft have had MADs for decades. They use it for final targeting before dropping a torpedo.
Frankly, I luv the military videos from Simon and co!
Well done, Simon!!! Thanks!!
This vid was well worth my time to watch !!
SmarterEveryDay has a good video onboard a US submarine. They can't say a lot because it's all classified, but they were discussing how sound waves can change depending on the depth and temperature of the water and how sound bounces off the surface of the water and the ocean floor and it just sounded so immensely complicated to figure out how the sonar equipment is able to transcribe this information into useful data.

You're amazing, thank you for always doing this ❤
the thing with submarines, is you could have the best, most modern underwater detection systems in the world, but a navy or air force can only search a minute fraction of the water at any one time, so finding submarines is still going to be super hard until they attack, or unless you can track transmissions to and from the sub
It was an informative and a great work 👍🏻 thanks for sharing..stealth started by rubber coats by Germany during WW2 and successfully passed over the USA 🇺🇸 and nowadays settled on Sweden 🇸🇪 submarines
You will find that all modern submarines will have anechoic tiles.
Another great video, Simon and crew! I would really enjoy a video on the Rolling Stones, the most famous long-lived rock band
That have not put out a decent album since 1981 and absolutely stink live for the past 20+ years.
Who?
I hope that you would make a video about the Chinese fleet of conventional submarines, such as the type 039 and it's various variants
The Seawolf class (3 subs only) warrants discussion. My understanding is that they are quieter than any current US sub in use, dive deeper, and go faster. I suspect the sound signature crown for US subs won't be lost by them until the Columbia Class enters service. Their big drawback was cost and not capability.
Ohio-class SSBNs running slow on natural circulation (no reactor cooling pumps) are also hella-quiet, but they were never designed to go on the offensive. Burn an entire country off the face of the Earth? Sure. Hunt an enemy sub? Only as a last resort.

I remember an exercise with the Australian navy where obsolete Oberon class submarine snuck up on one of the newly commissioned Colins class sub. Bit of a gaff when an old diesel powered sub was quite enough to do it
My dad sailed on the Oberon class subs for years... This wasn't even that uncommon for that boat. It was obscenely quiet when operating on battery/electric.
Given that France and UK's nuclear submarines collided with each other underwater, I would guess the stealth is pretty good.
Sheer incompitance they are always noisy
USS Conform is not mentioned here for some reason. It was planned to build in the 70-s and had a totaly stealth design.
Whispering death beneath the water. These subs are literally sneaky and so deadly.
It's interesting that most of the information in this video can be obtained from Tom Clancy's 1980's novel "The Hunt for Red October"
Magnetic Anomaly Detectors are actually not new technology. MAD saw use by the US Navy in antisubmarine warfare roles during World War II.
Specifically, it was installed aboard select PBY Catalina flying boats. These planes were dispatched to scout for enemy subs from the air. Perhaps inevitably, the aircraft soon became affectionately known as 'MAD Cats'.
MAD is not new, it has been used by aircraft since the 50s and maybe before.
Didn't the newer sub hunter aircraft abandoned MAD?
I remember reading something.
Note: Not an expert 😂
@@Shadow__133You are correct.
Everytime I see a vid on submarines, it makes me glad I was Infantry. Cheers from a former Grunt.
I wonder if any navies have tested some of those toroidal props on their ship and subs.
I'm sure some small-scale testing has been done and since most sub props are always hidden while the vessel is out of the water, maybe they have been used for a long time already!

Submarine technology today has come along way since ww2 .
We currently have AC launched drones that mimic the radar signature of whatever aircraft we it to. I see it being adapted for sub use.
The wonderful thing about baldness is being able to dispense with combs, brushes, and such. One less grooming concern.
Generally, diesel boats are quiter because they run off electric batteries, but they have to go up to/near the surface to run a diesel generator. Nuke boats can be loud because of coolant pumps and other pieces of the reactor system. That said, US Nuke boats are "holes" in the water. US nuke boats have a real advantage in how long they can deploy.
But don't the nuc boats get almost silent when making steerage?
I read somewhere that they don't need to operate the cooling pumps at such a low speed so the reactors can circulate steam by simple convection.
Back in the 90's Scientific American published an article about detecting underwater objects through reflected sound. In other words it wouldn't matter a damn how quiet you were, they could still detect you by the reflections of background ocean noise. The article showed a false colour picture of 3 dolphins in an enclosure. It wasn't done in real time, but it was still very impressive. I often wonder where that technology is at now.
Hi, I was just watching this (8:20-8:30ish) and with the sonar stealth, could one achieve with sonar, what "augmented see through" helmets, sorry i'm a layman on this (absorbing from one side, and rebroadcasts on opposite side of vehicle)?
very cool
Have you made a video covering the hadron collider (CERN)?
Submarines are awesome 😎👍
I was starting to get worried. Almost an entire technology video with no mention of AI. Reality was starting to crumble but you came through in the end. Well done.
Imagine just fishing on the ocean and then one of these things surfaces right next to you
In 2005, HSwMS Gotland managed to snap several pictures of USS Ronald Reagan during a wargaming exercise in the Pacific Ocean, demonstrating that it was in a position to sink the aircraft carrier. The exercise was conducted to evaluate the effectiveness of the US fleet against diesel-electric submarines, which some have noted as severely lacking.
Also a British sub followed an American aircraft carrier while directly underneath and wasnt detected all the way across the Atlantic
Just goes to show how much technology, design and engineering goes into making these awesome vessels
Now do a video on the P8 Poseidon. If sub warfare is a deadly game of Marco Polo, then the P8 is the kid that got out of the pool and started throwing things at all of the other players.
Magnetic Anomaly Detection is not new by any stretch. It was used all through the Cold War.
Sweden doesn't have submarines but submersible boats. The difference is that submersible boats rely on being able to surface as they cannot run underwater for long periods as they have limited power underwater.
We have one now though. In Gothenburg I belive currently but i could be wrong on location. My government doesn't state usually about the force or the amount unfortunately but a few things get told to us. I'm sorry my English not the best.
Rumors say Simon wields an Elite Silent Submarine as well
Aka the basement!
An unmand drone submarine... I think we already got this... It is called torpedo😂
Aparently submarine hunting is partickularly difficult in the Baltic sea, where Sweden operates it's submarines - but also has had to do a lot of hunting for Russian submarines. The difficulties arise due to layers of water with different salinity. I'm guessing that can act as layers of mirrors.
Conn, sonar! Crazy Ivan!!
Most silent swedish gotland klass😎
That GHOST acronym sounds almost as forced as SHIELD
Surprised that the Seawolf class wasn't mentioned.
What the _Virginia_ class submarines did was drastically reduce the noise signature of the nuclear drive system itself. insulating the noise of the coolant pumps and the driveshaft and putting the propeller spinner inside a shroud makes the _Virginia_ class submarine just about as quiet as a diesel-electric submarine running on battery power.
telling about stealth submarines, and forget the Germans new submarine for Norway/Germany. That one take active and passive stealth to a new level! I do find it interesting that just a few month after Germany/Norway presented the new submarine design, Russia presented a similar design, just larger and with nuclear propulsion (It is just an Yasen/Akula class, with a different outer hull!)
Neclear can never be quiet
You were incorrect. The diesel- electric subs were quieter. They were easily detected when they surface to recharge the batteries.
M.A.D isn't exactly new. Canada has been flying a version of the P-3 Orion with Viking-3 avionics since 1980. Designated CP140 Aurora, it features CAE Electronics ASQ-502 MAD. See the tail extension. I'm sure they've been around longer than that, as the MAD unit was also public knowledge in 1980, ie I got to see it at an airshow and they announced it.

Easiest way is to make a hell of a noise in the sea, drowning all these subtle sounds and signitures.
going the other direction in making a lot of noise, this is being explored in aviation as well. the F15 variants are heavy hitters and while the silent eagle would've been cool, those are the kinds of aircraft you want people to know are coming. saturating air defenses with radar signatures that mimic heavy bombers, hitting targets in large volume with cruise missiles like rapid dragon, it's ninjas vs. vikings now.
Ocean is a noisy place. You just look for the hole in the water, where the sound is least... Active is used for the torpedoes. And then they start out passive until the planned runout has expired. But a well placed ASROC will likely go active the moment it gets wet. May not sink the sub, but getting it out of action is key. I don't think there is an IFF system on torps. so you want to be out of sonar range.
The Swedish subs are much smaller, made for sneaking into shallow waters, not open Atlantic endeavors. With chilled oxygen made from sea water and sterling engines as electrical generators, they can as I understand run the engines on pretty much anything. Could Methane be possible? In that case, with their new A26 sub with underwater drone and scuba deployers, could they refuel by tapping into undersea power cables? Will that limit the time submerged to release of exhaust? (And food for the crew of course)
Hi Simon et al.
Is their any chance you could do a feature on Australia's AUKUS submarines? Some of us reckon they're nuts to even try if the idea is protection from China...
based on the quality of this clip I'd rather poke my eyes out with a broom handle. this was 15mins of bollocks. As soon as someone talks about speed advantages or even stamina as what nukes bring to the table then its pretty damn clear that they actually have zero idea about the actual capability benefits
I really find it amusing that a completly bald man is advertising hair growing products to me lmfao
The swedish subs and the german 212CD as well as other non-nuclear submarines showed the angular design way before russia. As usual...
I love how all these video, when you gets to the version of the tech that Russia "has" it's always a paper design that doesn't actually exist, compared to the US that has multiple working versions that have been deployed for decades XD
I take it, the only media you watch about what's been happening in a Ukraine is western main stream media. Because you'll find if you take your arrogant head from out of your ass. Do some proper research, you'll find all of the Russian military hardware has & is totally decimating every single Western sent hardware for fun. As for the Americans fantastic patriot system. It's been proven as totally pathetic & a complete waste of tax payers money that can't stop anything Russian uses. By the way they're the only country with hypersonic missiles in service. Take a look at how Russian air defence ststems have done the whole conflict. It's the reason atacms, hymars, storm shadow missiles despite being used thousands of times are being taken out at a staggering percentage. This is the real reason the US won't let its troops go anywhere near Ukraine to fight the Russians. Best air defences in the world by far. Best missile tech in the world by far. As for submarines. The Russians are the only ones who can make the whole skin of them using Titanium without any problems whatsoever. They also have by far & away the most modern missiles.
But no doubt you'll not believe a single one of those cast iron facts. But hey! as they say ignorance is bliss.
That's coz America is always at war with someone!
I'm pretty sure the submarine decoy launchable as you would a torpedo exists and has done for a long time, making noise and looking exactly like a submarine
Back in the 80s I had an American girlfriend who had been in Nuclear Submarine Tracking based in Norfolk Beach. She said she watched monitors that displayed signals from massive cables laid out on the seabed. Each submarine gives off a distinct signature from its propellers and that vibration is picked up by the cables. She said the only place they couldn't track subs was under the north polar ice cap but they'd just wait until it came back out after going under the ice. Now those cables are used by science to track migration whale pods because they can pick up the whales singing and identify particular whales.
Swedish subs are in another class 🇸🇪

Much like using a rangefinder through glass, the accuracy of using lidar to detect a submarine is extremely limited. The general location and an assumed depth are all you will get. This is enough to narrow down the search, but the mat black surface of a US sub may help it hide from lidar. Bubbles have always been an issue for submarine detection. From quick moving propellers boiling the water otherwise known as cavitation. As well as water pressure at the front of the sub being higher than the pressure along the hull. This pressure difference can create small bubbles that pop and are one method of discovery of a submarine. Active sonar is much like radar and is rarely used by a submarine. Active sonar uses a high-frequency ping to reflect off the surface of surrounding objects. The reasons for limited use of this are marine life side effects, and it gives away your position as well. Magnetic detection is by far the most effective method of detection but has a vary limited range. We can also hide a magnetic signature with the use of certain alloys and composites. Eventually, there will be technology that will find a current submarine with ease, but that's the same with everything. The objective is to stay ahead of the competition of both detection and avoidance.
You can already use modern SAR satellites to detect large submarines, when they are moving, as they are creating characteristic bow waves on the surface, that are only millimeters tall.
Any mention of Stirling engines?
They have technology that can hear a heartbeat 200 ft underground.
I love it . . . a bald-headed guy advertising a hair restorer product! Good video!
The major takeaway from this video gem is that hair loss stops with Keeps! : )
Modern active sonars are far more complex than the "ping" Hollywood used in The Hunt for Red October.
A nuke boat has cooland water pumps, steam generators, steam turbines and generators and lots of other stuff running at all times. There is no way any nuke boat is quieter than a regular old school diesel electric sub running silent on battery. Wich is why most nations have some kind of diesel electric sub for defending home waters. Nuke boats are only good for going fast and going far, but they make more noise then regular subs. Another factor is what speed the sub is going. Pretty much all subs can be nearly undetectable when they go slow, even some badly maintained soviet sub will be very hard to locate of its only going ~5knots. Going slow and silent, most subs are way quieter then ambient noise. Infact if there is bad weather or a storm, the ocean itself will make so much noise, its impossible to hear another sub until its right ontop of you. Wich is why allmost every year you got some sub collision with another sub or civilian vessel they didnt hear was there.
