How did the radar impact World War 2?

Battle of Britain - allowed for early warning of incoming air raids. Standing patrols of defensive fighters were nolonger necessary so fuel, pilots and planes were saved. The defensive response could be matched to the incoming raid increasing the chances of success. Battle of the Atlantic - Enemy submarines could nolonger hide on the surface at night to recharge their batteries. Attacks from airplanes could come at anytime. Morale and effectiveness of the U-boats was decreased. Allied subchasing groups had SONAR, the equivalent of RADAR to search below the surface of the cean to find the U-boats. Supplies came to Britain from North America. The U-boats were nolonger able to stem these supplies allowing for the build-up to the invasion of France. Churchill said something to the effect that Radar didn't win the war, but Radar won the battles that allowed the war to be won. Radar had a major impact on the outcome of WW2.
