as he pointed out in the video, buy showing several example of other submarines doing the same thing, it's not rare for a submarines as silent as the diesel electric submarine to do so. It's quite common, even among the older submarines vs modern fleet, they are just that silent. Sterling engine just give the submarine commander some extra moves on his strategy table. Other submarines that have sunk US carrier and other ships in exercise, is for example Ula class, they did it several times back in the 90's without the endurance of a sterling equipped powerplant. And it managed to get it self DNF from an another exercise, due to it was to effective... it sunk almost the entire enemy fleet on the first day and forced them to restart the entire exercise... But then Ula class was designed to hunt and defend against an massive Soviet fleet back then, it is it's speciality.

[@ollebrandt]

An honest comparison with the German modern silent subs would be very appreciated. As well as a proper strategical evaluation of the use of silent traditional subs in comparison with the much larger nuclear subs, mainly created for deep sea operations...

[@joakimwohlfeil]

Basically it's simple. The Swedish submarines have the performance edge but very complicated rules for export, and a smaller country for counter business (as most defences contracts comes with demand on return business). The German subs has the commercial advantage with NATO to NATO, bigger opportunities for counter counter investments and easier arms export rules.

[@ronaldderooij1774]

Well, nuclear subs are a little bit noisier, but much faster and have endurance until the end of the world. Diesel/electric subs are quiet when submerged and running electric motors. Otherwise they are very noisy and have to snorkel regularly to recharge batteries. This makes them slow, noisy at times and visible on radar. Also, diesel/electric subs are slow. So, if (and that is a big if) you can detect them outside 10 km radius with a nuclear submarine, you fire the torpedo, and with 100% certainty you destroy it. If the diesel/electric sub fires back, the nuclear sub is fast enough to outrun the torpedo before it reaches it. The only chance the diesel/electric sub has, is that it sits quietly at a spot where it expects a nuclear sub to pass in the vicinity and fire the torpedo from less than 10 km distance. Neither sub will probably survive that encounter.

[@secularnevrosis]

@@ronaldderooij1774 I belive that a 50 knots torp are a bit too fast, even for nuclear subs. I even don't think that the old Soviet Alfa could do that, not even if it was facing the right direction. And if it was doing any significant speed at all it would be noisy and detected from a longer distance. Decoys are also a thing that is used. The whole purpose of the AIP is that it doesn't need to snorkel to charge the batteries, not for 2 weeks that is. In the open ocean a nuclear sub has a big advantage as it doesn't need fuel and can keep high speeds for extended periods of time, but they are big and more noisy. In littoral waters they are at a disadvantage because they are big and harder to maneuver in confined spaces and shallow water, speed isn't even a factor that could be relied on when there are many obstacles and shallow waters. The encounters will also be at closer ranges where the size combined with the higher noise floor may be what determines if you are detected or not.

[@zhufortheimpaler4041]

@@joakimwohlfeil do they really have the edge? they are very similar in capability and performence. The 212A, 214 and 216 classes (the later 2 are export models) ar about 200t heavier and larger than the Gotland, but are also a bit faster than the Gotland, also the 212A is heavier armed with 6 heavy weight torpedo tubes. The main reason is the production run. Germany alone build 6 for itself, then there are 4 in Italy and about a dozen in other operators hands. The Gotland only has 3 in total. Btw the Kockums shipyard where the Gotland was designed and build was part of the german HDW Group when the Gotland was designed and build. HDW is the designer and builder of the 212A. Another reason why there was little export.

@@ornestal2615 I don't need to contact them, I already know the reason why. Don't get me wrong, I'm not specifically blaming the Swedish government or arms industry for anything because they aren't alone in their cowardice. Selling arms to Taiwan is bad for business. I get it. If Sweden sold Gotland class submarines to Taiwan, China would place tariffs on Swedish goods imported into China, or China could refuse to sell goods to Sweden or the PLAN could even harass Swedish ships at sea that have to pass through the Straits of Taiwan and the South China Sea. It's mafia-style intimidation, it works and there is nothing Sweden can do, economically or militarily, to stop it. So like so many other nations, Sweden took the easy route and decided not to sell to Taiwan. It's cowardly but I can see the logic behind it. If I were in Sweden's shoes I might have done the same thing. But please don't insult my intelligence by saying Sweden couldn't find a buyer for the Gotland Class subs because one was out there and at the right moment in history too. When the last (of 3) Gotland class submarines was launched in 1996, Taiwan was actively looking for more submarines to supplement the two Zwaardvis class subs they bought from the Netherlands in the 80s and to replace the two ancient WWII vintage submarines they acquired from the USA. At a build rate of one boat per year, Swedish shipyards could have had a decade worth of work, paid for in cash, not taxpayer funds. In other words, it wasn't a case of no one willing to buy, but Sweden's refusal to sell, which is a pity because I think the Gotlands would have been ideal for Taiwan and could have resulted in at least a half dozen or more submarine sales for Sweden which would have made the type a genuine export success that could have garnered even more sales.

The Russia Baltic fleet, for instance, has to pass a couple bottlenecks on it's way out to the North Sea. These can just sit there. Likewise an American carrier group is likely keeping station somewhere if there is an extended conflict, so AIP mode would be the final approach to the area. Now a carrier group even at cruising speed isn't going to be caught unless going almost full out and AIP isn't going to help getting out of town after launching torpedoes.

[@Samson373]

Few people tell the complete Tale of the Gotland, which makes readers think that carriers are more vulnerable than they are in real life. One exception is the Australian youtuber Hypohysterical. According to his more complete telling, as part of the war games the carrier was subjected to various artificial limitations, limitations that gave the Gotland a better chance of getting within range for a torpedo shot. For example, the carrier could use neither its sonar buoys nor its (simulated) anti-torpedo torpedos. There were other limitations that I can't recall, but I do recall that they would make a difference in real life. That is, the odds that in real life combat the Gotland could have hit the carrier are lower -- probably much lower -- than the odds implied by the incomplete Gotland Tale as it is usually told. The real life odds that the Gotland could've not only torpedo the carrier but also SUNK it are even lower. Lower still are the real life odds that the Gotland could not only sink the carrier but also get away without itself being destroyed. In short, the standard, incomplete telling of the Gotland Tale makes people think US carriers are much more vulnerable than they actually are. It might also make people think that diesel electric submarines are less vulnerable than they actually are.

[@pauljohnstone9275]

@@joakimwohlfeil I worked on Collins it is getting long in the tooth and I seriously doubt it can perform until the Virgina Class arrive. I am certainly one of those who view the Son of Collins as low risk high end capability incorporating new technologies such as non penetrating periscopes, potentially use Lithium batteries, take the AIP bought for those boats out of storage and upgrade and ensure that there is enough power to support the combat system at all times which does not currently occur.

The trouble with the stories aboaut various submarines *defeating* U.S. Navy battle groups is the nature of the contest. The agreed upon terms of the encounter go something like this. We will sail our fleet around in circles in a box a hundred miles by a hundred miles for a week. We agree not to have a dozen sonar dipping helos in constant operation within that box. You have a year to bring your boat and crew up to scratch. You have a couple of months to get your sub fueled, supplied and into prepositon in the box. We will provide the in theater fuel and supplies. We agree to temporarily halt the exercise if requested to provide the fuel and supplies if needed. You have one week from the start of the exercise to get your already prepositioned silent sub into a possible encounter. Let's see how you do. Results....once in a while the sub will win. Interesting and very useful for upgrading defenses. But not as significant as made out to be by some.

[@hemligx-sson8202]

😂😂😂😂 You must be a Merkin? A Gotland sub would probably fit in a loud mouth Merkins mouth. How many wars did you loose after WWII? 😂😂😂😂

[@johnhough7738]

I gave up. This (as far as I suffered) was just a whole lot of ultra brief-clips end to end. (As an old guy it takes me longer to focus ...)

[@losbexp]

You sound quite Turkish. Anyway, Gotland is cool but i prefer HDW's 212/4s for coastal defence.

[@jojoanggono3229]

I think Gottland class was not succesful commercially because they would not give any kickback to customer.

[@sveannnnnnn7578]

easy answer on question :politics, you buy your heavy stuffs from USA. countries are buying f16 instead of jas 39 gripen. even tho f16 only have 1 base in each country( EASY AS SHIT TO DISSABLE) and jas 39 gripen land and service in a shoppingmarket parkinglot , whats a f16 worth if u cannot service it ?

[@vmedhe2]

im sorry but A) thats not true for either fighter plane, and B) its scale 4600 F16s have been produced and licensed with US producing a plethora of spare parts and secondary markets for the plane. Jas 39 has like 300 units in total with spare parts in much shorter supply and available in limited markets.

[@recoil53]

I'm sure most European countries have more airstrips that the F-16 can land on, though I agree that the Gripen is made to land on roads. But Egypt and India have the people and parts to service the F-16, I highly doubt most European countries couldn't. Though again, I agree that the Gripen has lover service requirements. Which is why I want it for Ukraine.

@@sveannnnnnn7578 And the rest of mainland Europe? Germany is pretty big. A search showed that Denmark has one fighter base, one air base that for transports and can therefore land F-16s. There are also a large number of airports that should be able to land F-16s. Service has to do with parts and personnel and that stuff can be moved around.

This sub can beat US Navy As it has proven several times!! So to the point the US asked to borrow it, and they did^^ Best time was when the Gotland surfaced 30 meters from a aircraft carrier and have gotten past the protection^^ It shows that you don't have to be the biggest sub to win a battle^^

Sweden produces excellent weapons, but being a peace loving nation, she is self imposed and limited exports. The Gotland class is excellent but they are small, proper for littoral defense only.
