Sweden's ATOMIC Submarine

[@666zombee]

The sub that "sank" an American aircraft carrier during a war games exercise without being detected was a Swedish one

[@dereklinscott8488]

Sweden: Punching WAY above their weight in arms development while also kicking out excellent heavy metal.

[@mackereldude]

The stumpy lower rudder and low mounted diving planes would add stability to a submarine laying on the bottom in ambush. The Baltic is a fairly shallow sea making this a very viable tactic.

[@gzcwnk]

The water intakes though need to be high up to do that or you will suck in mud.

[@martinborgen]

Probably lots of people mentioning ASEA currently being part of ABB, but I just want to point out how ASEA back in the day was a real powerhouse of electrical engineering, pioneering several concepts, such as High Voltage DC transmission, and even developed their own world-class nuclear reactors (after US published some key research). They also manufactured pretty much anything else high-power electrical related in-house; Generators, turbines, elevators, welders, fans, locomotives, power transformers - the list just goes on.

[@osvagt]

This comment covered it all up...ASEA teamed up with Brown-Boveri and joined their HQ in Zürich in the late 80"s, and became ABB.

[@matsv201]

Well the sold of the gas turbines to Siemens, the steam turbines to Alstom, generators also to Alstom, The trains to Adtrans, then to Bombarder, then to Alstom, the atomic division to Westing house. Its pretty much just transfer lines and robots they make today

[@ollep9142]

There are a couple of technical reasons why nuclear power wasn't (and still isn't) a good alternative for subs used by the Swedish Navy: 1. The one advantage of nuclear power is that it allows the sub to stay submerged for a very long time. That's great if you're cruising the oceans, but less of an issue while doing shorter missions in/near an archipelago. 2. One disadvantage of a nuclear reactor is that while operating in the archipelago a minor navigational error might cause a radioactive disaster. 3. Another disadvantage is that a nuclear reactor requires constant cooling, and that cooling system is relatively noisy! It's impossible to lay all quiet on the bottom. 4. I also think a reactor, including containment and "safe zone" requires quite a bit of space that isn't really available when you try to minimize the size of the sub.

[@matsv201]

2: The reactor is in the back, so they have to ram into something really fast to damange the reactor. Even at that i kind of doubt it. If the reactor room is flodded, there is really no danger of overheating. 3: It really depends on how its reduced in power. If its alreddy in a low power stage the ramp down of power is quite fast and the need of cooling is very limited

[@webbtrekker534]

Really old thinking. The modern reactors have multiple safety features with automatic shutdown features. Have had those since the late 1950's and even better today. PS: I have first hand experience being aboard a nuclear submarine for months at a time. Don't listen to the talking heads. They are wrong mostly.

[@ollep9142]

@@webbtrekker534 1. Emergency shutdowns are not instant. 2. Reactors need cooling for years even after shutdown. With the presence of cooling being a problem in itself, either as a source of noise or as difficult to provide in/after an emergency, that's also an issue. 3. Even a successful shutdown of the reactor won't prevent problems if/when the core is exposed. Either as a result of a collision or, more likely, after being hit by a mine or torpedo. (As noted above my statements apply to relatively small subs for use in narrow and shallow waters. Not much room for fancy layers of physical protection of the core.)

[@matsv201]

@@ollep9142 well we talk a second or two for emergancy shut of. So its pretty much instant. The second point os sort of true, well kind of. But for gen III and specially so gen III+ rectors, the passive cooling is made so it will condense back. This gives them effectivly unlimited cooling. But also gen 2+ have features to both delay and mitgate meltdowns. There is also worth saying that there is 100 of zero power rectors around the world that nobody ever talk about, those are by far the most dangerus

[@killsode4760]

@@ollep9142 practically a necropost I know, but you're vastly overestimating how much of a risk submarine reactors pose, the only way they would produce a substantial environmental risk is if a wreck is left there to rot, or if it is blown apart in combat.

Excellent episode and really interesting. The newspaper clip in the Swedish paper describes an anti-nuclear demonstration in London. The signs with different country names are delegations from the respective country. The text also says there was Swedish representation in that protest. ASEA was founded in 1883 and is famous for its high voltage DC distribution and electrical engines. At the time, it was the critical nuclear business for the Swedish civil nuclear program. There are reactors still in use today. ASEA later merged with Swiss company Brown, Boveri, and Cie (BBC) and became the ABB Group, a well-known international company.

[@sharg0]

As a Swede I really appreciate this video, I had no idea we looked in to a nuclear powered submarine back in the days. Nor did I know that the A11 class was still in service!

Back in the 50's Sweden could maybe put 800.000 men under arms (7 miljon total population in the 1950's). The bulk of the defense force was crewed by conscripts and every young healthy Swedish man did about 1 year in basic conscript training, around 50.000 men per year. In order to get the whole machine going you need smart solution in order to reduce the need of man power (that was in short supply). Nato or the Warsaw pact didn't have the same kind of problem with shortage of man power. Hence the use of automation in the the Swedish weapons programs. The Swedish subs was manned by conscripts but the higher ranked officers was career employed.

Hi there ! It has been a while that I follow your content. I have watched almost all of your videos but I couldnt find the some answers that I am looking for. Hence, I prefer to write down on comments section about my questions : - I am interested in the Type 214 submarines and their problems in development phase. - Why did German Navy has refused to give order to Howaldtswerke-Deutsche Werft GmbH about Type 214 and prefered to stick to Type 212s? the Sub. 'd had balast and further balance problems at Papanikolis class submarines in Hellenic Navy. (Their test sub. was almost tipped over %60 side at the tests and almost turned upside down after the heavy torpido firing tests. ) - Turkish partners of that german company in Gölcük have declared that they solved that balance problems by increase the length by 4m and redesigning the balast tanks independently from the main design. German company officials verified that and they accredited and rewarded Navy engineers 2 years ago. BUT German Navy officials have still refused to buy eventhough the design problems were solved. What is really going on with Type 214s? - How does a 3K tons Submarine tip over or lose control by firing a 533mm Torpedo ? - Why did Pakistani Navy dropped the contract with germans after 2 years of waiting for that? there is something fishy and political with those submarines and I still have blindspots. I would be appreciated if you provide some info to enlighten me. Thanks !

5:46 I believe all USN submarines from the Gato-class forward (perhaps earlier) have been either diesel-electric or nuclear. In the case of the Gatos, each boat was equipped with four Fairbanks-Morse or General Motors diesel engines coupled to generators, which in turn either powered the four electric motors (two per shaft) or were used to charge the batteries. Normal procedure for surface operation was to run on three main engines-- two supplying power to the motors, one charging the batteries, and the fourth rested for inspection and maintenance.

Did the rotating magazine really need to rotate or could just multiple doors exist. Multiple doors would also address the wire guided problem, the tubes could be sealed till needed to avoid the immersed in seawater issue perhaps filled with a fluid friendly to the torpedoes and electronics so the seal wouldn't need to be a pressure seal and could say be a plastic membrane that would just be brokrn through. As to nuclear subs, was there any RTG subs where a radioisotooe generator which wouldn't be enough for cruising but might be enough for hotel services and trickle charging. Also, maybe do something about the civilian Sagan-N. The Sagan-N was to be a 8 man sub with a SLOWPOKE adiabatic nuclear reactor using Sterling engines to run the generators from the hot water produced. They built the hull for the Sagan-N but a tax dispute between Canada and France killed the project. Had the project continued, the nuclear reactor component would likely have been left out to cut costs amd reduce bureaucracy but still it was quite the concept.

I have no record of ASEA develop reactors for propulsion but I think it’s safe to assume a country of 6-7 million people don’t have more than a hand full of people, skilled in the atomic technology.

The US actually started to use the all-electric drive in the 30s with the diesel just running generators.

[@Cragified]

A small correction. The Porpoise class of U.S.N. boats had 4 diesels driving 4 electric generators being the first diesel-electric drives of the U.S.N. well before the 1950s. The Salmons went back to two direct drive and two electrical generator. The following Sargos were all electric drive in the late boats and that stuck from then on.

I'm glad you don't mind the idiots who write about audio. I can't hear a difference any way.

Very cool, I didn't know Sweden even had a nuclear program.

[@mistralx2475]

Great work!

[@kraftrad7840]

Excellent!

The Nautilus and Albacore are both museums now, and I think, well worth visiting.

Swedish engineering is amazing. A self taught engineer made one of the world's most cutting edge automotive companies: Koenigsegg . Also Swedish engineers were some of the first to call for safety features which are now universal. At a time when America's big automakers were stagnating on safety, Sweden had the tech. When Swedish engineers set out to do their bit, they do a top notch job. Sweden doesn't do any engineering project halfway. This is a cool sub.

Can you talk about the type 209 submarine it's one that's very common all around the world and without much Information

FWIW... ASEA --> ASEA Brown-Boveri --> ABB (one of the largest suppliers of electrical generating, industrial and electrical controls in the world)

With the 6 tubes surrounded by the rotary torpedo magazine, how did they fit a sonar? The bow looks very crowded.

Please double check your comment on Diesel/Electric propulsion. In WWII the Gato and Balao submarines were Diesel/Electric powered. Diesel generators powering electric motors that both propelled the submarine and recharged the batteries. Typically, upon surfacing two engines were dedicated to propulsion and two were used to recharge the batteries. Diesel/Electric is not new to the 1950 era. It has well established by the late 1930's.
