The Northrop F-89 Scorpion is an American heavy jet fighter, designed to operate in all weather conditions. The first flight of the prototype took place in August 1948, and the machine appeared in line units in 1950. The F-89 was a two-seat, cantilevered mid-wing, all-metal construction with a pressurized crew cabin. The crew consisted of a pilot and a radar operator. The aircraft had a simple trapezoidal airframe. Classic horizontal tail. It served in the USAAF from 1950 to 1957, later the F-89 aircraft were transferred to the National Guard units and replaced by the Convair F-102 Delta Dagger. The aircraft served in the Air National Guard until 1968. Several versions of the F-89 were built, the most widely produced of which were the F-89C with the new Allison J-35-A-21 engines and the main production version of the F-89D with the new Hughes E-6 fire control system, AN/APG-40 radar and AN/APA-84 computer. It is worth noting that the F-89 was the first USAAF aircraft to be adapted to use the AIR-2 Genie air-to-air missile with a 1.5 Kt nuclear warhead. A total of 1,050 aircraft of this type were built.
