The problem was that the USN wouldnt even admit that there was a problem for a long time.
I know torpedos are expensive, but didn’t the Navy test them before sending them out to the fleet?
I read that we tested two - one failed - so we went to war with a weapon that had a 50% failure rate.
Pre-WWII the military was starved for funds - I remember seeing war games with trucks having the word "TANK" painted on the sides.
