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.
The RC F-89 Scorpion scratch built by Mark Hinton has a 106 in. wingspan and is 100 in long. It features split ailerons and retracts. Construction is all composites. Power comes from a pair of 22 lbf. thrust turbojets. All up weight is about 42 lbs.
