The McDonnell Douglas F-4 Phantom II is a two-seat, twin-engine supersonic aircraft family that first flew in 1958. Developed by McDonnell for U.S. Navy fleet defense, it expanded into a widely operated family for air defense, reconnaissance, training, electronic-warfare, and other military duties. National and service variants introduced different sensors, structures, and engine installations while retaining the common Phantom II design.
