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

A world war two submarine fighting against another wwii submarine would be similar to a two blind men fighting each other in a 1000 yard space. They can yell (sonar) and listen (hydrophone), throw stones at a random locations (torpedoes) but at the end it is almost impossible to cause any harm to each other.
