The
Harrier, informally referred to as the
Harrier Jump Jet, is a family of
jet fighters capable of
vertical/short takeoff and landing (V/STOL) operations. Originally developed by UK manufacturer
Hawker Siddeley in the 1960s, the Harrier emerged as the only truly successful V/STOL design of the many attempted during that era, despite being a
subsonic aircraft, unlike most of its competitors. It was conceived to operate from improvised bases, such as car parks or forest clearings, without requiring large and vulnerable
air bases. Later, the design was adapted for use from
aircraft carriers.
