@Biofury:
Here’s another roughly accurate source of of GDP listings through-out the ages.
Thanks for that information. But while GDP figures are a useful thing to keep in the back of one’s head, I prefer to rely on military production figures for game design purposes. Below are some military production data for World War II.
Tanks
Soviet Union: 105,000
US: 88,000
Germany: 46,000
UK: 28,000
Canada: 6,000
Japan: 3,000
Italy: 2,000
Hungary: 500
Artillery
Soviet Union: 517,000
US: 257,000
Germany: 159,000
UK: 125,000
Japan: 13,000
Canada: 10,000
Italy: 7,000
Other Commonwealth: 5,000
Hungary: 400
Mortars
Soviet Union: 200,000

The Soviets produced 2.3 times as many tanks as the Germans, 3.3 times as many artillery, 2.7 times as many mortars, 2.1 times as many machine guns, and 83% as many military aircraft. It’s true these numbers don’t capture the fact that the Germans devoted a greater portion of their output to naval spending than the Soviets. Also, some of these differences are due to Germany’s late-war production problems. But Germany arguably reached its production peak in 1944; so its late war production problems only explain a modest portion of the production gap between itself and the Soviet Union.
