Supertest: K-91-PT Soviet Tier IX Tank Destroyer Incoming

3 min read

Today we have an exclusive leak for you. Yet another brand new Soviet vehicle will be coming soon™ to World of Tanks Supertest, you might have heard of the other variant earlier this month, the K-91 version II, but this time its the K-91-PT. The K-91-PT was the last of the three heavy tank proposals for the series and it had a rear fixed gun placement and was equipped with the same 100 mm gun D-46T as the first variant proposal.

Going by the average damage per shot and the rate of fire, I would believe this is still a 100 mm gun but with higher damage to fit the tank destroyer role contrary to the K-91 and K-91 version II, the vehicle is equipped with a fast-firing 122mm gun. The K-91-PT is coming to Supertest as a Tier IX tank destroyer, maybe to fit the Object 268 version IV gameplay, and will feature a crew of five, Commander, Gunner, Driver and two Loaders, and 30 pieces of ammo between AP, APCR and HE.

The hull armour features 230mm but no details are known about the superstructure thickness. With a low profile, the vehicle should have decent concealment and seems highly mobile for a tank destroyer. With a dispersion of 0.4 at 100 meters, proximity will be a friend to actually hit the target, but knowing how Soviet guns behave in-game, you might get the lucky shot from a distance and the decent rate of fire should enable you to try a second shot without much wait. More information will be shared as soon as it becomes available through Supertest.

Historical Background

The K-91 project had three variants proposed, the final one was a rear fixed gun emplacement, more know as a self-propelled gun or a tank destroyer. It featured the same 100 mm gun D-46T has the initial heavy tank proposal, but aside from the fixed gun, no other relevant changes were made. The tank was to be equipped with the same twelve-cylinder diesel supercharged B-64 engine and the torsion bars were very similar too. The distinctive feature was the use of extreme knots of trolleys with two all-metal rollers.

At the end of 1949, work on the K-91 project was discontinued, as they were inferior in most parameters to both existing and newer projects of heavy tanks. The project never advanced from the drawing stage with no prototypes ever built.

  1. they took k91 remove turret and add box give it gun and that was it clap clap WG

  2. The Object 416, Object 430 II and K-91 in the tech tree should’ve already been cl***ified as TDs rather than mediums.

  3. Legit, aint this just a low caliber Obj 268 Ver 2? Could have swapped out the Obj 263 at tier 9 for this and the tech tree would be more consistant…

    But WG says **** consistancy, gotta have one outlier in the tree and the on that would make sense as a premium
