eli5 Why didn’t the US or other countries make a similar submarine to counter Uboats?

Question

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.

Answer 1

The US and Britain both had large submarine fleets. Submarines at the time were useful against surface ships and not very useful against other submarines. IIRC, there was ONE successful submarine on submarine underwater engagement in all of WW2. Destroyers and escort carriers were more effective, so they used those instead against submarines.
