The chief designer who birthed the T-34 and died of pneumonia at 41
March 1940: he personally drove two unfinished T-34 prototypes 750 km through the snow to the Kremlin, started the engines before Stalin, and collapsed with pneumonia after the return journey.
A Soviet tank designer born to a peasant family, he began as a confectionery apprentice and only turned to engineering at 30. At the Kharkov Locomotive Plant he led modernization of the BT series of light tanks, then pushed the purely tracked A-32 project through, a design that matured into the T-34. In March 1940 he personally drove two unfinished prototypes 750 km through snow from Kharkov to Moscow, presenting them to Stalin at the Kremlin. The ordeal gave him pneumonia; he died at 41, nine months before the German invasion. His T-34 became the backbone of Soviet armored forces throughout the war.

A-20 vs. A-32: The Design Battle and Stalin's Intervention
When Koshkin arrived at the Kharkov plant in 1937, the mainstream of Soviet tank design still clung to the Christie-style convertible wheel-tracked drive. But the Spanish Civil War had exposed the BT tanks: they burned helplessly against anti-tank guns, and thickening their armor was impossible. The transmission buckled, and wheeled travel became impractical. The military brass insisted on a wheel-tracked hybrid, the A-20 with 20mm armor. Koshkin already saw the dead end.
In secret, he had his bureau develop a purely tracked alternative: the A-32. Strip away the wheel drive and you could pour the saved weight into armor and firepower. On 28 April 1938, at a meeting of the People's Commissariat of Defence, Koshkin requested permission to build a tank that had not even been ordered, a tracked-only vehicle. Stalin, present at the meeting, replied: 'Do not limit the factory's initiative.' Those words were the political breakthrough that made the T-34 possible.
In the summer of 1939 the two prototypes were tested side by side at Kubinka. The A-20 was faster on roads; the A-32 was decisively superior in cross-country mobility and protection. Koshkin went further, presenting an up-gunned variant, the T-32, mounting a 76.2mm cannon, and argued that this was the future of the medium tank. On 19 December 1939, Defence Committee Decree No. 443 adopted the A-32 with 45mm sloped armor as the T-34. A confectioner-turned-engineer's stubborn technical conviction had broken through bureaucratic inertia and redirected the course of Soviet armored power.
