10,000 tanks, and nothing on paper
On 20 July 1941, a month after Barbarossa was launched, the State Defense Committee (GKO) signed Decree No. 222ss: produce 10,000 light tanks. The problem is that the tank to be mass-produced does not yet exist on any drawing. At Factory No. 37 in Moscow, engineer has to decide very quickly.
3 paths lie open to him. Continue with the amphibious T-40 already in production, though its floating hull, complex and costly, slows down the assembly lines. Develop a more ambitious land-based version, better armored and better armed, at the cost of more tooling and longer delays. Or start over from an already-sketched non-amphibious prototype, radically simplified, one that could be built on existing automobile lines.
Every day counts: the Wehrmacht is advancing, and the has lost thousands of armored vehicles. The tank that is chosen will soon equip entire converted factories.
Chief engineer in Moscow, July 1941: which light tank to design for the GKO's mass order?
Astrov chose radical simplification. Together with Lieutenant Colonel Okunev, he wrote directly to Stalin to make the case for a non-amphibious tank, derived from the T-30B prototype, that could be mass-produced on automobile assembly lines. The plans were finalized in a week (drawings delivered on 28 July 1941). This tank became the T-60: flotation was dropped in favor of thicker armor, and on Malyshev's suggestion it received a 20 mm TNSh automatic cannon instead of the 12.7 mm machine gun. Mass production began, notably at the GAZ factory in Gorky (led by ), starting in October 1941. Nearly 6,000 T-60s would be produced: a modest tank, but one available in large numbers at the very moment the USSR desperately needed it.
