I’m watching a ton of WW2 documentaries and can’t help but think why they didn’t make a counter to the German Uboats other then depth charges and the hedgehog. Surely with the money and resources the US or other countries could of made a sub during that time.

The US did have a lot of submarines in WWII. They mostly used them to go after surface ships and to secretly transport Marine Raiders to occupied islands. (Gung Ho!)

Submarines aren’t very good at destroying other submarines. Destroyers with active sonar and depth charges did a good job at hitting submerged ones, and heavy attack aircraft with searchlights early in the war and radar later were good at hitting surfaced ones. And during WWII a submarine couldn’t stay submerged very long. They mostly traveled on the surface and submerged when they needed to hide.
