The Radar and World War II

The Technology of Allied Victory

The Weapon that Won the War

The radar was first used in Word War II by Britain and the United States to detect enemy aircraft. It uses transverse radio waves to determine the location, direction, speed, and altitude of oncoming craft. This gave them a considerable advantage, as it allowed them to respond faster.

The Battle of Britain

The radar allowed the British to defend against German bombers in the Battle of Britain. Because they were hopelessly outgunned (Britain had 800 planes while Germany had 3000), the British had to concentrate their efforts in order to defend themselves. Radar allowed them to concentrate where they knew there were Germans, instead of randomly spacing defensive measures. This eventually won them the battle.
