The F-89 Scorpion, built by Northrop, was an all-weather interceptor jet powered aircraft that replaced a number of propeller driven aircraft. It carried a crew of two consisting of a pilot and observer. It was initially armed with four 20 mm cannons in a moving nose turret. Unique to the F-89 Scorpion were split ailerons that were used to slow it. The F-89 Scorpion was nicknamed "Stanley steamer" due to its very large landing gear wheels.

The F-89 Scorpion, model D, had its six 20 mm cannons replaced with large rocket pods on each wing which housed fiftytwo 70 mm unguided rockets each. It carried the APG-40 targeting radar that had a 50 mile range, and the Hughes E-6 fire control intercept system. The aircraft could carry the AIR-2A Genie, a nuclear armed air-to-air rocket.

On July 19, 1957 a F-89 Scorpion flying over a Nevada test range launched a live nuclear armed Genie rocket. It flew approximately 2.65 miles before detonating. It was the only time that a U.S. aircraft ever accomplished such a mission.

Eventually the F-89 Scorpion model J became one of the first aircraft ever to carry guided missiles.

U.S. Air Force F-89 Scorpion aircraft flew from 1950 to 1959, primarily tasked with protecting the skies around the United States. The U.S. Air National Guard continued to fly them 1969. A total of 1,050 F-89 Scorpion aircraft of all types were produced.
