RADAR signals travel way further then their effective return signal treshhold.

true, but in modern warfare, the key to survival is detecting your enemy before he detects you.

In the Pacific, the U.S. Navy showed what a huge tactical advantage Radar could be. By 1944-45, U.S. fleet Boats were attacking heavily escorted IJN convoys and Task Forces on the surface at will.

The reality of the battle of the Atlantic is that after Radar became standard equipment on Allied escorts/airplanes in 41-42, U-Boats were at a huge disadvantage.
