Ha, there you go. They're not 'Uber' they're 'Realistic'.

so how come uboats were so sucessful then in the early years of the war???

I would think that it was a mixture of - lack of training, lack of supply/installation of equipment & the fact that tactics had to be developed to counter U-Boat attacks.

It's still a big ocean/sea. The U-boat has a fairly large target, while the escorts had a small target.
