The KV-1 Model 1941 was produced in two major production runs: an early version with more or less the same hull and chassis as the Model 1940, and a later version with an up-armored turret, in both cast and welded options. The welded version is currently found in-game as the KV-1 (ZiS-5).

This tank would be functionally the same as the existing KV-1 (ZiS-5) in-game, warranting the same BR.

 

OVERVIEW

This is effectively the KV-1 (ZiS-5) in-game but with the cast turret as found on the KV-IB 756(r).

It's a bit harder to see, but the rounded turret and rear hull are present. This is an early example still featuring the old fashioned road wheels.

HISTORY

 

Partial Copy-paste from my KV-1 Model 1941 (early) suggestion: https://forum.warthunder.com/index.php?/topic/457960-kv-1-model-1941-early-long-arm/. It is rather brief as I have written multiple other development histories of the KV-1 tank.

 

 

After the creation of the KV-1 Model 1940, uparmored and armed with the F-32 gun, the need was once again seen to up-gun the KV-1. The T-34 had recently been fitted with the powerful F-34 gun, leaving the L-11 and F-32-armed KV-1 tanks behind in firepower. To match it, the F-34 gun was adapted into the ZiS-5. This was a special version designed for the KV-1, but was overall very similar.

 

The ZiS-5 was fitted to the KV-1 chassis in the first half of 1941, creating the Model 1941. Otherwise, the platform was unchanged. The hull armor of 75 mm + 25 mm was retained, as was the original turret with 75 mm thick armor. 

 

In June 1941, it was discovered that, while standard German AT guns struggled against the KV-1's armor, heavier guns such as the 88 mm AA guns or 105 mm field howitzers could become potent tank killers. As such, plans were quickly made to up-armor the KV-1 again. The Model 1940 tanks with the F-32 gun were converted to the KV-1E, while the Model 1941 began production with a new turret with 90 mm of armor.

 

The new Model 1941 was also produced in one of two ways: with a welded turret, like in-game, or with a cast turret. This was split roughly evenly in terms of numbers, although later photographic evidence seems to suggest more cast-turreted tanks as production continued. The Model 1942, which saw minor revisions to the tank, was also produced. Production of the KV-1 ended in 1943, being beaten out by the T-34.
