 To handle this attack, in the post-World War II era the Royal Air Force deployed the ROTOR radar network that covered the entire British Isles in order to attack any strategic bomber that might attempt to approach.The defensive weapons of the system included new jet-powered interceptor aircraft and, originally, reorganized anti-aircraft artillery with new tactical control radars.By the early 1950s, the increasing speeds and altitudes of bombers meant they could "toss" their weapons from ranges outside even the largest anti-aircraft artillery, and plans began to replace these weapons with surface-to-air missiles.
