T-34 and KV tanks, with their powerful armament and armour, showed themselves well in combat. However, due to a lack of diesel engines which have a rather low lifespan (100 engine-hours), a number of these tanks are unsuitable for combat.
There are no engines at NKO warehouses, and it is necessary to issue 20 engines for KV tanks and 150 engines for T-34 tanks. Based on projected engine usage and the current technical condition of tanks, we will need to replace 450-500 engines in July.
In total, before the end of 1941, based on the calculations of one engine per two tanks, it's necessary to get:
- V-2K (for KV tanks): up to 1000 engines
- V-2-34 (for T-34 tanks): up to 2000 engines
