Pansarvärnspjästerrängbil 9031 (Pvpjtgb 9031)


Summarized history:

The Pvpjtgb 9031 is a light unarmored terrain vehicle, which were based from the transport version of said vehicle aka.: Personlastterrängbil 903 (Pltgb 903), which were introduced in the 1960’s. Compared to the transport version, the Pvpjtgb 9031 had its chassis modified to accommodate the Bofors 9cm pansarvärnpjäs 1110 (The name of the cannon was originally designated as: " 9 cm Pvpj m/59"). However, the other reason for this was due to previous tests. In which they tried to deploy the gun onto the more conventional Pltgb 903. But, during the testing, they realized that there is a high risk of the recoil flame of the cannon would set the rear part of the vehicle on fire. The Solution came with a new chassis from Volvo. Which gave the vehicle a much lower profile and less total weight compared to its original counterpart. Which caused the vehicle to have a much higher max speed which it was not intended to have originally.

There were several accidents which occured for the Pvpjtgb 9031, which is due to the lighter weight and the cannon mounted onto the vehicle. Mainly it was prone to flip if you’re driving too fast and/or suddenly having to hard break, alternatively if you’re driving the vehicle in a steep angle. Due to the cannon mounted onto the vehicle, it increased the total weight at the front of the vehicle. Which will cause the overall weight distrubution going to the front, rather the center of the vehicle. After several of these accidents occured with the vehicle. The Swedish armed forces decided to modify the Pvpjtgb 9031 to accomodate a foldable roll bar onto the vehicle, to reduce injuries to the crew and vehicle itself. The reason why it was foldale, is so that the crew can aim and fire the cannon in a much broader angle, compared if the roll bar was a fixed object. See image below:


The main armament for the Pvpjtgb 9031 is the Bofors 9cm Pansarvärnpjäs 1110 recoilless rifle. Which was used both as a anti tank gun and a support gun against fortified positions or infantry. That means it could fire the same types of rounds which the Ikv-91 can use (with the exception of the shell), however it could not use any High Explosive rounds. The only rounds it had available to use was HEAT/HEAT-FS rounds (You can read about the ammunition types on the next paragraph). The cannon equipped with a binocular sight with x4 magnification and ontop the the cannon itself: a modified Automatgevär m/42 (AG 42) chambered either in 6.5mm or 7.62mm NATO and were designated as: Inskjutningsvapen 5110. It was used as a secondary armament and carried 20 rounds per magazine. While being a secondary armament, it was primarly used for rangefinding for the Bofors cannon. As the gun itself was adjusted so the bullet path becomes as similar to the Bofors Cannon as possible.(See images below).

Note: Up to 4 containers of additional 9cm Bofors rounds could be placed on the vehicle (See below):


The Pvpjtgb 9031 along with the Pltgb 903 was used extensively by the Swedish armed forces throughout the 60’s and started to phase out by mid 1970’s. As the vehicle started to be replaced by the more modern TGB 11 (Terrängbil 11) . However, due to the large amount of delivered Pltgb 903 and Pvpjtgb 9031. As well the amount of spare parts to them, the vehicle continued to serve the Swedish armed forces till the late 1990’s. The 9cm Bofors Recoilless Cannon which the Pvpjtgb 9031 used, would also be put out of service around the same timeperiod. However instead of scrapping all of the cannons, the Swedish Goverment transfered the ownership of around 300 9cm Bofors Cannons to the newly formed Baltic nations of Estonia, Latvia and Lithuania (As it was during the time when Soviet Union collapsed and the Baltic states reaffirmed their independence).

Give sweden our own speedy rats!!


I hope we get proper traverse since gaijin isn’t fond of animating the bodies in complicated or dynamic positions which might be needed.


+1 for Swedish Fiat 6614


Does this mean the ikv 91 could also theoretically get the 800mm HEAT shell?


No its a different cannon and ammunition.

As well as stuff online saying:

Pansarvärnspjäs 1110 - Wikipedia
The same projectiles were used in the main armament of the Infanterikanonvagn 91 although with a different casing.


Ikv 91
Den medförda ammunitionsmängden till kanonen var totalt 59 skott (varav 18 skott i ammunitionsstället till höger om föraren) – normalt 39 st Spårljuspansarspränggranater m/72 (Slpsgr) och 20 st Spårljusspränggranat (Slsgr) m/72. Under senare hälften av 80-talet tillfördes Slpsgr m/84 – en ammunition som hade en hårdnos som skulle möjliggöra genomträngning i explosivt reaktiva pansar

Which translates to:

The amount of ammunition carried for the cannon was a total of 59 rounds (of which 18 rounds in the ammunition rack to the right of the driver) - normally 39 Track Light Armored Explosive Grenades m/72 (Slpsgr) and 20 Track Light Explosive Grenades (Slsgr) m/72. In the latter half of the 80s, the Slpsgr m/84 was added - an ammunition that had a hard nose that would allow penetration of explosively reactive armor

Slpsgr m/84 being the same round as for this recoilless rifle

Unless I’m missing something and it’s the same calibre and shell names but they can’t be fired from the other gun?

The short awnser is that both the IKV-91 and the Pansarvärnspjäs 1110 (equipped on the vehicle I’ve suggested). Both has the same caliber and ammunition type. But due to the differences to the ammunition casing mentioned in the URL link you’ve posted. Made the shells incompatible with one another.

As the IKV-91 has a 90mm low velocity cannon. While the Pansarvärnpjäs 1110 is a recoil-less rifle. So the casings has be adjusted accordingly to the weapon.

So yes, you’re correct. With what you said.

Okay, so it’s different shells, but the ikv 91 still has a slpsgr m/84 round? It’s just different to the slpsgr m/84 on the Pvpj 1110? but maybe it would have had similar performance?

God, i’d be the fastest damn rat on the field with this bad boy


That I am actually not sure of to be honest. Haven’t looked into that specifically considering this is a suggestion for the Pvpjtgb 9031 and not the IKV-91. But from what I’ve red, the IKV-91 should also be able to use the m/84 round as well. Which you kinda already posted and exists on the sources I’ve used for the suggestion.

Oh yeah, I just wondered if you had any information seeing as they appear to be similar haha. No worries anyway :)

Suggestion passed to the developers for consideration.
