McDonnell Douglas F-4 Phantom II (1964)

The classic third-generation fighter, used by the Air Force, Navy, and Marines, had two crewmembers. The backseater, the Radar Intercept Officer (RIO), managed the new and advanced radar system. Designed to carry only missiles as its armament, later versions incorporated a gun form lessons learned in Vietnam. The F-4 is still in service with various countries around the world, and is one of the most produced fighter jets of all time.
