The requirement for two turret designs comes up again.
"T-34 tanks built with a 76 mm gun: 540 (18%)
T-34 tanks built with an 85 mm gun: 2449 (82%)
Additionally, it must be remarked that when transferring to an 85 mm gun, factory #112 had to master two types of turrets in 1944, one for a D-5 85 mm gun and one for an S-53 85 mm gun.
The armour of the tank was increased. The factory began producing tanks with variable armour: front - 90 mm, sides - 75 mm, rear - 52 mm. Only tanks with the thickened turret are being produced as of November 1944."
