Operation Typhoon began #OTD in 1941, marking the start of the Battle of Moscow. The plan called for massive pincers to grip the city from the north and south, but only a tiny German force even made it close to Moscow before the tide of war turned. #tanks #history #WW2 #WWII

Tankograd was created not just by relocating existing factories, but by reallocating new ones to tank production. #OTD in 1942 the first T-34 tanks were completed at UZTM in Sverdlovsk, which previously built heavy construction machinery and tools. #tanks #history #WW2 #WWII

#OTD in 1943 factory #627 proposed a 50 ton heavy tank with an electric transmission. The proposal was declined, but a very similar tank was eventually built: the IS-6 (Object 253). This tank was only a prototype and was not accepted into service. #tanks #history #WW2 #WWII
