The Cold war was a competition between two economies – and Soviet Union, and the USA. Each tried to outspend the other – primarily on munitions.
I was an Electronic Engineer then, and I made a lot of money off that war, with the exotic Radars we had, to detect Soviet bombers armed with nuclear bombs.
The Soviets had no such bombers – but we did, ready to take off on a minutes notice. The crews slept right next to their bombers – and they were programed to bomb a number of targets, in succession. The crews knew they were unlikely to survive one of these missions – but they were going to go, anyway.
The amount spent on one bomber, and its bombs – was unbelievable. But we had plenty of money then – and we were pretty sure the Soviets didn’t.
