  1. 1. Should the KV-1 Model 1942 be implemented?

    • Yes, in the tech tree
    • Yes, as a premium (please explain)
    • Yes, as a gift/rare (please explain)
    • No (please explain)

The KV-1 Model 1942 was the last major design of the standard KV-1 tank, before giving way to the KV-1S and later the IS-2. Throughout Model 1941 and Model 1942 production, a new cast turret was introduced. The only other major change to the design of the Model 1942 was the simplification of the rear hull. This is the variant of KV-1 upon which the KV-IB 756(r) is based.


The cast turret variant of the Model 1942 is the version I am suggesting.




In actuality, the differentiation between KV-1 models is even more confusing and less straightforward than T-34s. Various sources disagree, and the series of changes seem to be inconsistent across photographs. Regardless, this KV-1 I am suggesting is the last series production model of standard KV-1. The only remaining Model 1942 with the cast turret seems to be the one at Parola. However, the Finnish swastikas make it not Gaijin-friendly, so I will not include photographs of it. The KV-1 pictured above has the correct turret but not the correct hull.


Considering how similar this KV-1 is to the standard KV-1 (ZiS-5), they would easily have the same battle rating, and possibly be put into a folder together.



This tank is very much like the KV-1 (ZiS-5) (aka KV-1 Model 1941). The defining difference is the new cast turret, with slightly better anti-ballistic characteristics. Other changes are mostly visual or too minor to consider, such as a new rear plate or different road wheels. 




The cast shape of the turret is very clear.


The rounded shape and new rear machine gun mount are visible on this cast turret. This is actually a Model 1941 with the cast turret, as evidenced by the rounded rear plate and older style of road wheels.

The angular rear hull is clearly visible on this KV-1 in the center. It can also be seen that both cast and welded turrets were produced concurrently. 




The KV-1 first entered service in 1939 as a prototype. The Model 1939, armed with the L-11 gun and with 75 mm thick armor, proved to be the best of the 3 prototypes sent into the Winter War against Finland, beating out the T-100 and it's own big brother, the SMK. As such, the new KV-1 was put into production as the USSR's new heavy breakthrough tank, replacing the T-26 and T-35, and to an extent the T-28. At the same time, the T-34 was still being brushed up.


Before the KV-1 even saw its first mass-service, plans were already made for its upgrade. The L-11 gun was known to have lackluster anti-armor firepower, and the drivetrain was unreliable at best. So, not long after Model 1939 production begain in 1940, the Model 1940 was created, being re-armed with the F-32 gun. It also received extra 25 mm plates welded to the front and upper sides of the hull. It was an improvement, but still not perfect, and the mobility problems still weren't solved. At the same time, the T-34 had just been approved for production, itself being armed with the L-11 but soon to be converted to the F-34. 


Later once again, after the T-34 had received the F-34 gun in January 1941, the KV-1 was re-armed. It was fitted with a special variant of the F-34, the ZiS-5, and created the Model 1941. A few other minor tweaks and improvements were made to the drive train, but the issues of being overweight and unreliable were still present. 


When war broke out in June, the KV-1's armor proved to be quite the tough nut to crack. It seemed the only guns which could reliably destroy the KV-1 were the 88 mm anti-aircraft guns, and the often overlooked 105 mm field howitzers. In response, the Soviets made two types of upgrades to the existing KV-1 tanks: Model 1940 tanks were fitted with extra turret armor, creating the KV-1E, while Model 1941 tanks were produced with a new turret with thicker armor, creating the KV-1 (ZiS-5) that we see in War Thunder. The turrets on the new Model 1941 tanks were 90 mm thick. It was also at this time that the cast turrets began production, being 90 to 100 mm thick, depending on the production. The cast-turreted tanks were otherwise identical to the standard welded turret tanks.


By now, the T-34 had also proven its worth. For much less cost, the T-34 offered the same firepower, more mobility, and, in some cases, comparable armor. The KV-1 was outclassed. To add insult to injury, the tank was still plagued with many issues, such as unreliability, heaviness, and poor mobility. Excluding some of the wild prototypes created around the time, the solution to simplifying and lightening the KV-1 was created. Or so it seemed.


In spring or summer 1942, the KV-1 Model 1942 was first introduced. It was mostly the same as the Model 1941, except the rear hull was simplified and new, lighter road wheels were introduced. Even with these improvements, the KV-1 still was far from being competitive with the T-34. 


The other plan to save the KV-1 would be the KV-1S. It reversed the changes from the previous years, by reducing the armor. It received a new turret with a cupola, and a new planetary transmission. Overall, the tank became lighter and more reliable, but even this wouldn't save the KV-1. The KV-1S replaced the KV-1 in full by early 1943, but was itself cancelled later that same year.

I would love to see this variant added. We even have most of the model done in-game already as the German KV with the 75mm is the cast version.
