During the first years of WW2, the Swedish army had seen the success of German assault guns and tank destroyers – it was decided that these types of vehicles were to be introduced to the Swedish armed forces as well. TNew tank destroyers would be under direct command of the brigade commander and were meant to support tank companies with mobile and powerful anti-tank guns

In 1942, 87 tank destroyers were ordered from Landsverk. The new design was to be based on the Strv m/42 medium tank, but would feature an open-topped superstructure instead of a turret. The vehicle was to be propelled by a newly developed 380hp engine from Volvo and equipped with a new mechanical gearbox. The front would be 70mm thick and house a high power 75mm gun. The layout was fairly conventional, with transmission at the front, open topped crew compartment in the middle and the engine in the rear. The weight of the vehicle was not to exceed 23 tons. Perhaps the vehicle’s most impressive feature was the gun traverse, which reached 15 dg to each side, as well as the depression of 15dg and elevation of 25dg.

Late prototype (note the rounded front)


In Winter 1943, the first prototype was finished. It was based on the Strv m/42 chassis with a mild steel superstructure, mounting a 75mm L/50 Lvkan m/30 anti-aircraft gun. Rhe production version was however fitted with a more powerful 75mm L/54 Pvkan m/43. However, by 1944, when production was supposed to begin, only a few prototypes were ready. This was caused by major problems with the new gearbox. The suspension of the vehicle also had to be changed to accommodate the added weight to the front of the vehicle. What this meant was that the 4 front road wheels were replaced by strengthened ones. Problems with the gearbox continued and the first vehicles were only delivered with the designation Pvkv m/43 in 1946. By this time, the war was over and the vehicle had become the most delayed Swedish vehicle of the war, with 4 years between it being ordered and the delivery of the first units.

Production vehicle


In 1944, Sweden had nothing to combat enemy heavy tanks, and it was thought that the Pvkv m/43 would not be able to fill this role either. Therefore, a proposal was made to build a “heavy” tank destroyer on the Strv m/42 chassis. The vehicle would share the same type of gun mount as the Pvkv m/43, but it would have the superstructure located in the rear of the vehicle. This was proposed to allow the mounting of a massive 105mm L/50 Lvkan m/42 anti-aircraft gun, that would have been able to knock out any tank of its day. The project was however never realized. Instead, a development of a new TD started with the same gun on a new chassis, but that would ultimately be canceled as well.

My estimation of how the 10,5cm armed Motorlavett m/42 would have looked


During the years after the war, the Pvkv m/43 was the only Swedish vehicle capable of fighting modern tanks and it would stay that way until 1953, when Sweden bought the Centurion Mk.3. Because of this, there was a series of proposals to either upgun the Strv m/42, or to rebuild them to Pvkv m/43 vehicles with a more powerful Lvkan 75mm L/60 m/36. And before that, there were plans to rebuild the vehicle to have better armor sloping under the designation Pvkv fm/48, but this never did lead anywhere, as the 23 ton weight limit didn’t allow the use of heavier armor. Instead, the front armor thickness ended up being around 47mm and the project was cancelled.

Pvkv fm/48


In mid 1950′s, the Pvkv m/43 was rebuilt with a fully enclosed superstructure, the gun was also fitted with a bore evacuator. The modifications increased the weight of the vehicle to 25 tons. The biggest problem with the Pvkv m/43 was the Volvo engine, which had proven to be very unreliable, therefore in the early 60′s, when older engines became available, the engine was swapped for a dual configuration of the Scania Vabis L603, which provided 324hp. In this configuration, the Pvkv m/43 would continue its service until 1970, when it was finally phased out.

In World of Tanks

In the game, these vehicles would make perfect candidates for tiers 5 and 6. The Pvkv m/43 would function well at tier 5 with decent armor and good gun depression and the Motorlavett m/42 would fit perfectly into the evolution of Swedish TDs at tier 6, even if it would have to pay a price for having such a big gun. The Pvkv fm/48 could make for an interesting hull option for the Pvkv m/43, or possibly a tier 4-5 premium TD.

  1. They pretty much look perfectly fit for tier VI/VII.

    And they are somewhat pretty too.

  2. This is awesome, and if WG can’t make an entire swedish branch from all this I give up.

    • The Swedes certainly have plenty of tanks for a pretty much full tree, and heck even if they don’t get a full tree they can certainly quite easily get a tree similar to the Japanese; If that is the case, then WG will have made me a very happy customer. I am lovin’ some of the high-tier choices for the Swedes.

  3. Out of curiosity Silentstalker; are you going to be talking about the Pz58, Pz61, and Pz68/88? I hope so, cause those three tanks seem like great choices for tier 8 9 and 10 (starting with Pz58 and ending with Pz68/88 of course)

      • Sweet. Looking forward to that. But seeing as how long it’s taken to get to the point we are right now with these Swedish tank articles, i’m guessing those three will be around part 12 or 13 or so? Lol :-P

          • Aw man…Derp. :( Had to burst my bubble didn’t you? Well, those three could be part of the EU tree then i hope.

  4. Pvkv fm/48 with advanced 75mm gun (Konisch levels), upped engine, and a tier 5 medium tank chassis with KV-1/equivalent armor as “tier 4-5 premium”?

    Seems like 99% of player treemakers are great at coming up with the information and the history but super-overestimate it when placing it in WoT. Motorlavett m/42 is again a medium tank chassis but this time with a high-power 105 that outguns the Tiger II. I would have the Pvkv m/43 as tier 6 and Motorlavett m/42 as tier 7. Pvkv fm/48 I would not include, but if I had to, tier 6 premium.

    • the Pvkv fm/48 was meant to carry the 7,5cm pvkan m/43 which is a pretty standard tier 5-6 medium tank gun with around 100mm of penetartion and its armor is just 47mm at the front, te only things it has going for it is the mobility and 55kph top speed (and gun traverse i guess). In my opinion it would be best as a tier 5 premium or hull option for the Pvkv m/43 since that was historically what it was meant to be.

      And the Pvkv m/43 has no buissnes in tier 6, for that tier it would need a unhistorical gun (or a unhistorical penetration buff). the stug 3 outclasses it in all respects at tier 5 except gun traverse and depression, so i dont think it would be owerpowered.

      Also regarding the Motorlavett m/42. Several TDs at tier 6 carry high power 105mm guns including the S35 CA and the Dicker Max. There is really no reason that it would be owerpowered with its severe lack of mobility of around 14hp/t. And while the vehicle could possibly be balanced at tier 7 there are better candidates for that tier.
