Beginning in 1959, it set 15 world records for in-flight performance, including an absolute speed record and an absolute altitude record. Later models incorporated an M61 Vulcan rotary cannon. The F-4, like other interceptors of its time, was initially designed without an internal cannon. It can carry more than 18,000 pounds (8,400 kg) of weapons on nine external hardpoints, including air-to-air missiles, air-to-ground missiles, and various bombs.

Phantom production ran from 1958 to 1981 with a total of 5,195 aircraft built, making it the most produced American supersonic military aircraft in history, and cementing its position as a signature combat aircraft of the Cold War. Proving highly adaptable, it entered service with the Navy in 1961 before it was adopted by the United States Marine Corps and the United States Air Force, and by the mid-1960s it had become a major part of their air arms.
