Vulnerability of the T-34 and T-70 in combat operations of 1942

Moscow Research Lab TsNII-48 collected and statistically processed material on the vulnerability of Soviet tanks T-34 and T-70 in combat conditions. Material collected from Repair Base Factories No.37 (Moscow), No.112 (obtained from GABTU) etc. They examined 178 tanks T-34 and 70 tanks T-70.

* the determination of calibres made by diameter of hole in armor. Thus for example the 20 mm should rather be attributed to the German 50 mm HVAPs.

154 T-34 tanks (of total 170) took the defeat of armor, it was only 534 hits, of which 54% (289) safe and 46% (245) dangerous. Among these 154 tanks 38 vehicles (24,6%) were burned out and and 7 out these 38 were also damaged by mines.

The distribution of these 534 hits between hulls and turrets:

hulls - 432 hits - 81%

turrets - 102 hits - 19%

The every tank had from 1 to 17 hits; 116 tanks (75,3% of total tanks) had 1-4 hits.

Among examined 70 tanks T-70: 58 tanks (82,8%) had defeated armor protection and 12 tanks (17,2%) arrived for repairs because of deterioration of the engine (9 tanks), running gear (1 tank) and 2 burned out tanks.

212 hits distributet between these 58 tanks; 69,3% dangerous and 30,7% safe hits. From these 58 tanks 25 (42%) had burned out and 2 tanks (3,4%) hit by mines.

The distribution of these 212 hits between the hull and turret:

hull - 66,5%

turret - 33,5%
