Stefan knows what we really want for Christmas. You sir, and your staff are awesome.
YES!!!,, Karlsson in the S-Tank is back, God Jul & ett Gott Slut & Gott Nytt år.
Good stuff. Nothing like a straightforward knowledgeable presentation.
With all your cross overs I didn't realize I wasn't subscribed to you.
thanks for the deep dive on this, stefan! a great holiday treat - and may you and everyone at the museum have a great holiday season - love from canada! 😊
More videos of the stridsvagn-s please. Such an unique and interesting tank.
Thank you for the deep dive, I can imagine many sleepless nights when it came to designing this. Seasons greetings!
This was fascinating. Seeing a complete gun and power pack removal from the S tank was a treat I would be extremely unlikely to see otherwise. Thanks for a great video, I really enjoyed it. Cheers and happy holidays!
When I was in the British Army, I was in a Cavalry regiment (tanks), I was shown a film on the S-Tank, and was impressed! Unlike most of my fellow soldiers, could see where it was coming from. As a defensive weapon, it was brilliant!!! Like the Stug 3, it was an answer to a defence question!!!
Thanks, that was fascinating - not a cm of space wasted.
Zdravím Švédsko z České republiky nádherný stroj 😊❤ Martin
Id be happy to visit your museum!
Thanks that was an interesting insight into an interesting tank. The gunner being the driver means you wouldn't want this guy chasing you, there is no delay, his finger is on the button! It's a wonder this concept hasn't reappeared.
Fantastisk video, Tack Arsenalen 👍
Very interesting, I would love to see a feature film from that engine room. God jul och tack för allt jobb ni gör.
Aloha; mahalo for the in-depth presentation. Mele Kalikimaka! Mahalo
That just about the coolest how to guide ive ever seen, ever, in my life.
That was a great video thank you! I always thought with the engines you only ran the Detroit for slower driving and the gas turbine for combat. Kinda like on some naval ships. I'd love to see a video about Swedish Centurion main battle tanks since they did some considerable upgrades to them like the Israeli's.
Thats how we mechanics did it in training in 90/91 if we had to move them or testdrive them.
Mer sånt här! Kanon bra
my oppinion is that when it was introduced in the 60s, the Strv 103 was about as advanced as the moon lander and the apollo rockets..
thanks for the great video!
Appreciate you posting this. Was very interesting. Hopefully we can see this tank doing some maneuvering and firing in the future. Merry Christmas 🎄 everyone
Fascinating. Tack
That powerpack is really interesting ❤
This than is an engineering dream 😀
@@petter5721 And probably a maintenance nightmare ;)
Fantastic video
Learned a lot! Thanks for the detailed overview!
Great video ! I visited this year because of your videos . I also enjoyed your other military museums ,but I missed a few . I'll have to go back .
Right, I've visited the museum back in 2016 and would definitely like to come again.
Glad to here that our videos are appreciated! You both are very much welcomed!
Thank you Stefan et al for an excellent and highly informative video. Have a good Christmas and New Year.
Thank you Stefan, and Happy Holidays to you and everyone at the Arsenalen Tank Museum
That is a great video. It is so interesting to see what's inside (most of my toys got disassembled when I was a kid). It would be very cool if Mr Karlsson would tell more about components and how do they work. Like transmission and hydraulic system. I was quite confused to see the shaft under the power pack with some other shaft running across between final drives. As far as I understood, the power pack delivers the power to the final drives through the steering mechanism in the front of it. So the shaft under is is doing what? Delivering a power to a hydraulic pump located in front of the firewall? And also the thick pipe going from front under the shaft to back? And the vertical aiming actuators are somewhere? I think this vehicle does deserve more in detail video, especially on general layout and all that plumbing and shafts.
God Jul 👍🏻
thank you
fuckin awesome mate
A real treat to see a powerpack removed! And it's a Detroit!
Great vid , have a grand Christmas and all the best from sunny troon Scotland 😊
I always like seeing videos on the S Tank
That was great! Thanks very much.
Merry Christmas Stefan and all the best for 2024
Vill minnas att vid separatkörning GT att gt´ns hydraulpump på den drivande kretsen startade efter en stund och indkatorn slocknade. därmed fungerade den distrubuerande delen med hydraulmotorn. Pumpgruppen är ju värd ett eget avsnitt... Tycker nog att det är fusk att inte använda den fältmässiga bockkranen när motorn lyfts ur. Nästa avsnitt kan ju handla om laddautomaten , laddning rök, tempering spräng, plundring. Ta gärna ur magasinet (hyfsat lätt)...
Maybe you also can dismantle something else in this tank? Control system and hydraulic will be interesting to see.
1950's hydraulics... That must be fun!
Are ypi faschist
@@abaialsa712 Not at all... I really don't like hydraulic fluid leaks, and that thing must have been a nightmare for the poor soldiers that had to repair it.
@@MsJoao101 Yepp, i developed a hatered for that awful smelling ,and if old enough a biohazard, hydaulic fluid used in them because when i did my service in 90/91 we started getting more major breakdowns in the hydraulics because of age and abuse. And if i remember right the central catchtank alone holds more than 150 litre. So if something major breaks or spring aleak that shit gets everythere.
@@plasttjur I feel you. I never worked on tanks. I did repair and maintenance work on hydraulic lifts, cranes, diggers, stuff like that, a fully pressurized circuit leak will rip a finger out of your hand, or the hand out of your arm, it's not only toxic it's down right murderous and back then those fluids where even more awful then today's ones... Nasty stuff!
@@plasttjur Still the S-Tank will always be very cool!
Great video. And, in depth knowledge of a former tank commander on the actual S tank. A true testament of very novel thinking and engineering in Sweden at the time. Even though it can't fire on the move it can do better than any T80 or T90 what I see most tanks in Ukraine do. Come out of hiding quickly go into pre planed position fire a few acurate rounds that hit faster than any missile against armour of the enemy or any target not in range of artillery and scoot back. 105 mm rounds are far cheaper than any missile. This begs the question was night vision ever installed and was thermo imaging ever considered? And, was add on armour ever considered? A tank that if need be can be fully operated by one man is an enoumous asset. Is the S tank still in reserve storage. As the Russians prove a tank is a tank even when it's a T62 out of the scrap yard. And, as a former Dutch Leopard 1 tankdriver and PRTL / Dutch Gepard (anolog now updated digital versions) fighting in Ukraine in a viable cost effective with ammo way. 35mm rounds are cheaper than missiles. The AA tanks and MBT's are still there. 21:10
Regarding if they still are in storage the answer is no, they went to the scrapyard after the Leopards went in service.
@@plasttjur with hinsight and the knowledge of the Ukraine war that doesn't seem a wise decision. The cost of mothballing them would provide quick urgent tanks after say half a year during war. Especially with upgrade kits.
Question for Stefan: I see that the paint is scraped off from the end of the barrel... Was it common to bury or scrape the gun into the ground by accident, and did this ever cause significant damage to gun barrlels? Thanks for a great channel.
How do you compare the use of S-wagen to German Sturmgeschütz, which performed quite well for Germans and especially for Finns?
How to un-powerpack a christmas present.
The most interesting concept in tank history, a tank, even capable of fighting with one soldier, but highly complicated, in my opinion the addition of a turbine - nothing against that - makes the gearbox extremely complex. A bigger diesel combined with a small APU might have been a cheaper variant.
The problem was that a bigger diesel engine at the time would take too much space inside the tank for the Defense materiel administration requirements for the 103. Remember, this tank was designed in the late 1950ies!
If i remember correctly they were looking at that to.
Bear in mind, the S-tank was developed to defend Sweden and only Sweden in a brief defensive war, much as the Finns had done in 1939-40 against the USSR. Swedish tanks didn't need to be fast to produce because no war Sweden could sustain would last long enough to make much use of new production tanks. If the standing tank fleet couldn't "win" the fight, a few more vehicles rolling off the production lines were not likely to make the difference. What could matter was if each tank was so optimized for defending Sweden that they could "win" in the first weeks of the fight. S-tank was intended to be the "flank guard" for the Swedes, the tank that could secure the under-developed countryside against enemy attempts to swing wide around the heavy infantry and armored formations defending the direct routes to Sweden's strategic places like Stockholm. To that end, S-tank needed to be very small and very light and very fast to use the small wilderness roads and low-capacity bridges that dominated Sweden beyond the coast and old farmlands. A gas-turbine offered the best power for the size, so it was ideal for S-tank because it could be much smaller overall, allowing it to go more places to potentially outmaneuver. Do note, the Swedes kept heavy diesels in the heavier Centurions, because the extra-weight didn't matter where Centurions were intended to fight, down in the developed South along the coast and the old farmlands with tits many broad roads, firm fields, and robust bridges.
It is strange since I can swear the turbine was running some kind of petrol or aviation grade fuel. But anyways the power seems to be all American so hard to even know what a cubic inch is. Ice cube sized or potato sized? Jokes aside. It seems like the right choice at the time. Few numbers of expensive vehicles made to very special needs or wants. The piston engine being just a must since it should be the engine running the show when the gun is needed. And the turbine being the thing that gives it the power to maneuver. Like remember the air weapon in Sweden was also complicated. Used gas turbines (but rather then a final drive and gearboxes it drove a prop/fans and stuff over simplified.) and I'm not a aircraft nerd but it also has some important flaps and controls that are hydraulic yea? And even if it had 6 gearboxes so what? It dose not matter that you only have 1 gearbox if it is just junk. For being 6 gearboxes it seems very compact. It is limping back home or into safety easier then most modern cars even! Like a fighter yet has problems it is allot more problematic then a tank that maybe still can limp into a position to be a tank! It is still such a wild design. 6. How can that be even possible. But something tells me the hydraulic engineers life was pure hell! Even now it seems incredibly how much is accessible ones the pack is out. It was the British normal tanks that did the traditional tank duties. Whiles the S-Tank had only one role and that was a highly mobile rapid fire defense weapon still capable of much of the traditional tank duties. It seems more like a aircraft for the ground. Like how the Saab cars where some of the first true road turbo cars and very strange and unique. Whiles the Volvo bricks where like the Centurions and whatever else with a turret. Just dumb and trying to avoid being over engineered. Meanwhile the Germans somehow managed to make something far better and without any armor or nothing. Still incredibly advanced and effective yet simple! Leo. I still preferer driving in traffic and seeing a S-Tank then a Centurion or like really anything else armored. Remove that 1 meter extra from the gun barrel and it seems like the most road friendly tank ever made with such capabilities. Just have a look at the driver and commanders view! They can frankly get a round off in traffic and call it a time waste and road justice! Since it seems that capable even without a turret to actually have the controls and abelites to keep to the road and still get a shot in. Just incredible. Most likely a reason for the 6 dam gearboxes being needed is that ability to driven this crazy thing. It is honestly scary looking at the engine pack and engine bay. Add some garbage black plastic parts and serious wire and boxes of junk all around it? And yea the rust removed. Well it looks like a modern highly complicated and expensive to run vehicle. And this thing was designed and used pre 2000! It is remarkable. And 4 000kg of stuff to cover the crew compartment and then add on a nicely angled upper and lower plate etc? Like unless you are attacked from the rear where the ammo is stored or directly side on? Like dam. Even the CV90 looks like a joke compared to this insanity! The Saab of tanks seems like a good name for this engine bay.
@@TheDiner50 the thing with a turbine is that it can be trimmed in to run on any liquid fuel that can be atomised by it's fuel diffusers.
it would be really interesting to see how effective the S tank would be in Ukraine - brilliant for ambushes but I suspect t has a high heat signature with the Gas Turbine and vulnerable against Thermal Imagers
Is that a 551 or a 701 in the background at 11 minutes in? Or aka "dashing avenger". Would love to see that in a future video. Tack för ett fint jobb!
Hasande hämnarna 😂
Ja, en Pvrbv 551
A most interesting video. I never appreciated the complexities of the S-Tank's systems. One question, however, why were two entirely different engine types used? Why not two diesels?
Not really sure but I think the turbine engine was for extra power and especially to start the tank in extreme cold Swedish winters
The turbine engine has a much better power-to-weight ratio than a pistol diesel, but they have some drawbacks compared to a regular piston engine: they are extremely loud and smoky, they produce an extreme heat signature with all the hot exhaust gases (even if IR optics weren't really a thing back then) Turbines also run on very high rpm's. It is essentially an aircraft engine. A piston engine is better suited to power the hydraulic systems in the tank, everything from steering, aiming and operating the autoloader. The hydraulic pumps probably work on a lower rpm/ higher torque. The typical diesel engine of the era is an "inline-configuration" wich results in a very tall engine, as the pistons travel vertically inside the engine block. This is the types of engines found in stuff like trucks, farming tractors and tug boats. Rugged, reliable, relatively fuel-economic, and very easy to work with. But a bit bulky and heavy. A normal piston diesel, powerful enough to power the tank, would be so tall, it wouldn't fit with the low profile of this veichle. You can see that even this piston engine is way taller than the turbine, even though it has much less horsepower. Just for an interesting comparison, the CV90 Infantry fighting veichle has a modern V8 Diesel from Scania. That engine is very powerful, but the V-confoguration makes it more compact than an inline engine of the same cylinder volume. I wonder if it would fit inside the S-tank?
If anybody wonder what the signs on the engine that says "Trampa ej här" means, they translate to: don't step here. Hope that helps.
hur lång tid tar det att plocka ut motorn?
ca 8 timmar inkl allt
with such a successful design in many ways (low profile, single operator, long barrel for precision, presumably cheeper to build etc) why is it that it hasn't been copied and used today? is it only because it can't really fire while driving?
Hade den inte en Rover motkolvsmotor i någon version?
Inte Rover men Rolls Royce K60 innan man bytte till Detroit
