For instance, aircraft production rose from 15 thousand in 1942 to 40 thousand in 1944, while tank production approximately doubled over that span, according to Paul Kennedy's "Rise and Fall of the Great Powers." Yet many weapons in the latter year weren't properly deployed because of lack of fuel.
I was wondering whether Germany's war effort might have been better served by producing fewer weapons and using the fuel savings to deploy them better.
But perhaps that isn't the right question. So the question is: How did the fuel expenditure needed to produce a tank or airplane compare to its fuel usage over the course of say, a year?
I know that Albert Speer's mass production techniques had a lot to do with the productivity increase, so could the allocation of resources to production as opposed to use had something to do with Hitler's greater trust of Speer than his generals?
