Phantoms were replaced gradually in the various services by several different aircraft. The US Navy phased them out in favour of the F14 Tomcat. In the USAF the F15 Eagle displaced the aircraft and in RAF units the Phantom was largely superceded by the Panavia Tornada in various marks. The fact that one aircraft type was replaced by all these shows the great all-round ability and high importance possessed by the F-4. The Phantom largely replaced the BAC Lightning in RAF service.
