Hello everyone,
those of you, who are playing World of Tanks for a while do probably remember that at one point, the tier 6 medium tank, T-34/85, had an option to mount the 100mm D-10T gun. This was actually quite historical – there was an attempt (a prototype) to mount a 100mm gun in the T-34/85 turret and today, we’re going to have a look at it.
The reason for the proposal to actually upgun the T-34/85 was the fact that even in 1944, it was clear that the 85mm-equipped tank was inferior to the Panther, when it came to guns and improvements were in order. The first step was to first install a high-power 85mm gun (ZIS-85-BM) with improved penetration capabilities. This happened in September 1944, when Factory No.192 developed this powerful gun with the muzzle velocity of 980 m/s. After the development, the gun, now designated as ZIS-1, was transferred to the Gorokhovetsk proving grounds, but the trials proved to be the a failure.
In the beginning of October 1944, the design bureo of the Factory “Bolshevik” tried to develop an 85mm high-power gun as well – this time it was an experimental 85mm V-5 gun with the muzzle velocity of 950 m/s. Additionally, the factory also developed a conical gun V-9K with muzzle velocity of more than 1150 m/s. But the characteristics of the gun were not satisfactory, the gun was barely able to keep up with the dreaded German 88mm L/71 and in the Spring of 1945, the development was cancelled.
