Harrier Jump Jet The Harrier, informally referred to as the Harrier Jump Jet, is a family of jet-powered attack aircraft capable of vertical/short takeoff and landing operations (V/STOL). Named after a bird of prey, it was originally developed by British 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,
First-generation jet fighter led by Kurt Tank and was based on initial designs for the Focke-Wulf Ta 183, the proposed successor to the Me 262. The Pulqui II itself was a successor to the I.Ae. 27 Pulqui I, a prototype jet fighter developed in Argentina by Emile Dewoitine in the late 1940s and the first of its type to fly in South America. By the 1950s, the next major group of fighter aircraft were planes that used air-to-air missiles as their primary armament and could routinely exceed the speed of sound in level flight. First-generation fighters were limited to engagements in visual range,
