The Germans’ various rifle factories were producing Mauser 98s at the planned rate of 10,000 per month. At its peak, Springfield Armory alone (which had been tooled up more like a modern auto plant than a rifle factory) was cranking out about 4,000 M1 Garands a day.
We produced so much ammunition that .45ACP from WW2 was still in stock into the 80s (albeit repackaged in the 1960s), and .50 BMG ammo from the 1940s turned up in inventory as late as the Gulf War. Fortunately, there were a few troops that still knew how to work with corrosive primers....
I recall some quote from high school history class. Some German General after the war said something like “We would shoot one bomber down, and the next day the Americans would send 8 in place of it.”
From that same class I recall the teacher (Mr. Herzog - he was great!) talking about how great the German jet fighters were. Except Germany was so low on fuel, they would cart them out to the runways using horses!
The lesson being of course - you can have all the latest technology, but if you don’t have the raw materials to fight - you’ll lose.
He was also the coach of our debate team. I recall the one night in adjoining motel rooms, and we could hear him yelling at the T.V. with the movie “Tora, Tora, Tora” on full volume!
