With the top attack on tank nowadays like NLAW/Javelin do. A new design s-tank with entry/exit on the back instead of top on normal tanks. Wouldn't that prove a way of making a tank safe nowadays

[@dominiqueboy666]

I am happy and honored that Stefan shared his interesting and fascinating story with us. It is admirable how much he loves his passion. I think Stridsvagn 103 is an amazing tank and engineering masterpiece, it's very good that there are people in the world like Stefan who take care of such a beautiful technical wonders

@LukkyLuke80 modern day tanks are break through vehicles , The turret is essential.

[@goranewald2993]

Did my military service in 1980 as a sergeant with the S-tank. Lots of hours in the garage and I hated cleaning the 3 KSP-58, almost as tedious as cleaning the gun on the tank. Luckily we got a mechanical gun brush working with compressed air doing the heavy in and out pushing and pulling work named Baldur. Lots of maintenance work, as is said in the video, as we were only three to do all the work. My fun memories are brewing coffee inside the tank with the little electric kettle (fogging all optics), making hot sandwiches on the gas turbine exhaust (well wrapped in foil) and the rear driver keeping vodka in the smoke grenade magazine on winter manoeuvres. Winter was fun! Got more power from the gas turbine and did triple pruetts on the frozen groud in 50km/h. The memories come back……

True, I wonder how a modern 'electric' version of the same concept would fare? Gas-turbine, or the 'Mother-of-all-LiPos'? (Caution - they tend to fizz a lot when shot-at etc. - ask Hammond : )

[@MrDportjoe]

@@BoleDaPole If you look though what might be in that market is likely to be older than what they began the war with. The stuff that nations like Serbia, Estonia, Hungary and Poland upgraded from. Some of that has already been sent to Ukraine. The Brits, Germans and US tend to have moved most of the stock either to allied nations OR de milled and scrapped for parts, use as static displays/museum pieces or even sunk as artificial reefs. Also the Leopard 2 (which is still very much a front line MBT) has a range on full tanks of about 250km per full fuel load (road and X country mix) The Abrams manages only 200km range cross country of 200 km BUT refueling with jet fuel can be needed every three hours or so in mobile opeations.

As a defensive design it's fantastic! Get into a prepared position to cover the lower hull or on the rear of a slope and there's virtually nothing showing for the the enemy to aim at, and what is showing is severely sloped.

I much agree with how one commentator put it: an ambush tank. Select favorable terrain. Dig in. Hunker down. Fire. Reverse. Repeat. The S is my lifelong favorite. At 72 y.a., I remember it fondly as almost an alien vehicle compared to humdrum tanks by the thousands. Sort of like a Volvo or Saab (which I still own and treasure) compared to a Vauxhall or VW. The S's designers had imagination galore.

[@grumblesa10]

Sweden had very unique requirements that dovetailed into their national strategy. They did not need to be offensive weapons, and a "super-STuGIII" made a lot of sense. Historically the most effective tank killer the Germans had, on any front, was the STuGIII and for the same reasons. It had a good gun on a small, easily concealable chassis; using tracked-mobility to displace from firing position to firing position.

[@Shenordak]

It's a missunderstanding that it wasn't an offensive weapon. What Stefan meant is that Sweden wasn't going to invade anyone, not that the tank would only be used defensively. The role of the Swedish armoured and mechanised brigades was always to launch a mobile counteroffensive against a Soviet bridgehead in southern or central Sweden.

[@pakkazull8370]

@@Shenordak this exactly. People keep parroting that it's a purely defensive tank but it definitely was not according to doctrine

[@christianwall7181]

This episode is superb. A really heartfelt chat with Stefan’s passion (and self-deprecation) coming over so well.

[@hedge58]

The S-tank (or strv 103) was purpose built for defensive action against an invasion. Considering the AT weapons available at the time of designing it (1960's), it is a really clever design. The profile is low, which is excellent not only for concealment but makes it much harder to hit (if, for instance, your adversary mainly uses APFSDS-penetrating ammunition.) Also the front is really well armoured and the flat angle of it made it really difficult for any AP/HEAT/HESH rounds existing at the time to connect and penetrate the front. Nowadays we have powerful top attack munitions and they would have spelled disaster for the S-tank. The top and sides weren't well armoured, so it wouldn't stand a chance in a modern conflict. Maybe if one were to plaster it with modern ERA, it could still sort of make it, but then you have the issue with the gun which is not by any way up to par with Abrams, Challenger or Leopard's guns. I do think it could do well against the T-62/64/72 tanks though, after all - it was designed to take out those types of vehicles. I saw many out in the woods during my military service, and I still love it despite all its debatable quirks and flaws. As a matter of fact, I have a scale model of if in my bookshelf. Bought at the very museum Stefan curates. I highly recommend a visit if you happen to be in the vicinity of Strängnäs city.

[@nickmail7604]

Sweden was always expecting to have to fight a defensive action coming most likely from Russia, so to design a tank that in essence is more of a mobile, defensive pill box than a traditional tank with more offensive capabilities probably made perfect sense to the designers of the "S" tank.

[@pakkazull8370]

It was meant to be used as a traditional tank according to doctrine though

In 1954 the movie "To Hell And Back" came out. I was 12 at the time, and living in a small town in Wyoming USA. They parked a tank in front of the theater for publicity purposes. I remember crawling inside the tank(I don't remember what tank it was, but in my mind I thought it was a Sherman). As with the narrator, that experience has stayed with me all these years. This was a time with no internet, u-tube and wee didn't have a tv. Something like a tank parked in front of the movie house, and be able to actually crawl inside, and then watch a movie about the most highly decorated American veteran of WW2, was really amazing, especially in a small town in the middle of nowhere.

[@jp-um2fr]

I joined the MOD at Chertsey as an appretice at 15. If I remember correctly the S Tank had a Rolls Royce K60 as a 'run about' engine and it's gas turbine for battle. Just to sort of prove myself - did you ever get the power increase from the K60 you wanted and how well did they do in your patrol boats ? You could have used the Chieftain (BMC ruined) L60 but you would never have got as far as the hanger doors in the early days. The Sturmgeschutz did well so why not the S Tank.

Always fun to note the difference between Stefan and the guys from the Bovington museum.

Just a point - they are all extremely knowledgeable and interesting to listen at.

[@gorbalsboy]

I think it's obvious that the reason he looks like a mechanic is besides being manager, curator and god's know what else he has a very small staff of mostly volunteers and operates on Avery small budget and does wonders with it whereas Bovinginton has been established for a very long time ,has a far larger budget and therefore people can specialise.your implication that one is better than the other is based on a flawed supposition ,all the best

[@darreng745]

I would have said that because Bovington can employ tank mechanics they don't have to really go in hands first where as Stefan relies upon volunteers and has a far smaller budget so a lot of work is literally hands on. But all things aside it is nice that we have an ex tankers view of the S tank and the why of it's use inservice along with his practical experience of serving in it and the problems that the crews faced, you don't get that with Bovington I am afraid to say in the main. The knowledge that the staff there display is phenomenal, yet there is the missing element of personal inter action with rthe AFV's in army service

This is a critical point that many 'top trump'/gamer 'enthusiasts' miss is the doctrinal application for the hardware developed. In this case the S-Tanks were designed to fight a purely defensive engagement. Sweden was a steadfastly neutral country at the time, with a long history of neutrality. So, in that mind, all they needed was what was effectively a mobile AT gun. Their doctrine was very much a defence in depth, to retreat slowly and cause as much difficulty and losses to the enemy as possible in the process. It's the same with the commentary surrounding the M4 Sherman (which is thankfully starting to shift, in no part due to the hard work from the likes of Nicolas Moran), about it being rubbish and underarmoured and undergunned for it's role. It's role was to be a single do-it-all tank that could serve in all the different theatres that the Allies waged war, and to be able to be transported there in numbers. For that it was the perfect design. For the Swedes at the time, the S-Tank was what they needed.

[@barkebaat]

[@Lonewolfmike]

The thing with the S Tank is, as he stated, it was more complicated than most tanks were at the time. When you have something more complex you run the risk of having more things failing, but how it was going to be used, from all I have seen, it was the tank that they wanted and needed. That is what people either forget or don't think about is how Sweden was going to use the S Tank.

[@tasman006]

Great vid he didn't talk about the S tank being the first to have a turbine engine and also a back up deisel engine. Though overall it was a unique tank for its time and I think it would have been okay defending agianst the Soviets if they invaded.

[@lelleeriks8241]

Some claim it was a anti-tank vehicles but in the real world it was an MBT, Main Battle Tank. The Swedish Army's doctrine, tactics and exercise with the 103 was largely the same as with Centurion. That it was the best in the world for a period is about the fact that the technologies that made S-tank mediocre were not yet developed, good enough or did not exist in sufficient numbers with our imaginary enemy. In 1971, Strv 103 was the car that was most difficult to detect. Without towers and very low, the imaginary enemy had two problems. First, see it and once it has fired at them, identify the threat as a tank and not as an anti-tank cannon. That advantage disappeared when the Red Army introduced different types of gadgets that looked in the infrared spectrum. The S-tank turbine engine sent up a plume of heat above the wagon. So even if the 103 was hidden behind a crest, the Russian could not miss it. The cannon on Strv 103 was longer in 1971 than on comparable foreign tanks. It had two benefits. The exit velocity (and thus increased penetration at all distances) and a smaller dust cloud front tank (when the grenade travels longer in a cannon barrel reduces the pressure when the grenade leaves the muzzle). The recoil from a shot affected the 103 less as the unique design completely took care of that force and placed the cannon in exactly the same position as before the shot. Since the cannon and vtank did not move relative to each other during firing, a fast automatic lodder system could be designed. Which still today has a world record. One shot every three seconds! Since the enemy had a very hard time detecting, S-tank could shoot first. There is talk in the tank world about "Shot first-Kill first" and "Hunter-Killer" ability. Stabilization for the cannon / tower was developed so that it was possible to shoot during movement and that the commander could automatically send target indications to the shooter, which meant that the commander could more quickly concentrate on finding the next target, before the first was fought. In 1971, that technology was not good enough. "Hunter-Killer" ability had Strv 103 from the beginning when both commander and shooter could drive, aim and shoot. In 1971, there was no ammunition that could penetrate the S-tank from the front. A pretty good advantage, right? When the Soviets began manufacturing the T-62 and T-72, they developed a new type of arrow projectile with tungsten at the head. Tungsten is the metal with the highest melting point and an extreme tensile strength and very heavy, properties that prevent it from deforming when it hits steel armor but pushes it away. In 1994, the Swedish defense fired an S-tank with a T-72 loaded with an arrow projectile. The shot went straight through the tank. Not so good! The T-72's cannon has a caliber of 125 mm, 20% more powerful than the S-tank. Strv 103 came into service as early as 1968, but I still choose 1971. This is due to improvements in what is called sub-series B: Stronger engine, floating equipment, reinforcement plates in the rear, barrel protection and smoke throwers. Strv 103 B was finally delivered in 1971. I apologize for my poor English but I hope you still understand me. Do you guess what my nationality is?

There's one standing at the entrance to a military base (Revingehed) about 15 minutes drive from where I live. I pass it from time to time, sometimes I stop and take a closer look at it. It is indeed a fascinating piece of engineering.
