Decree #GKO-1062ss

On T-34 and T-60 tanks
NKTP and comrade Malyshev must:
- Begin production of T-34 tanks with an armour screen bringing up the front armour to 60 mm starting on January 15th, 1942, and then solid 60 mm armour starting on February 15th.
- Begin production of T-60 tanks with an armour screen bringing up the front armour to 35 mm starting on January 15th, 1942, and then solid 35 mm armour starting on February 15th.

However, nothing is permanent.

That did sound like a reasonable upgrade actually.
ReplyDeleteIf an increase to 60 mm on the T-34 hull had gotten past the design stage (one would assume this since the order was "begin production"), while I can understand why the change was not made in 1942 (not until the tide had turned at Stalingrad, with production being sacred) why wasn't this change incorporated into later T-34s, including the T-34/85?
ReplyDeleteThe biggest shortcoming of the T-34/85 was that using 1944/45 standards, its armor was on the thin side. An increase of 13 mm on the hull front and (better) the turret front would have made its resistance to the most common German medium AT weapon, the 75/L48, excellent save at very close ranges.
Increased armour thickness was attempted on the T-34-85M project, there it was decided that the effect of additional armour was not enough to offset the increase in weight and other complications that arose from it. I think that 60 mm would have been a reasonable increase, but I guess Soviet engineers knew something that I didn't.
DeleteI heard from somewhere it was a bit front heavy (?). I can't remember where, so I'm not challenging the tanks record, but perhaps the 85mm gun mount in the new turret may have raised/caused problems with the balance of the tank and tacking on 15mm might have been a valid reliability concern
