# F-89 Scorpion units of the United States Air Force

The Northrop F-89 Scorpion was a subsonic second-generation jet interceptor of the United States Air Force. After a long development during the postwar era of the late 1940s, it began reaching operational units in the early 1950s. A stablemate of the North American F-86D Sabre Interceptor, the F-89 replaced the first-generation Lockheed F-94 Starfire interceptor, primarily in the Air Defense Command (ADC). It was phased out of active service in the late 1950s, being replaced by supersonic McDonnell F-101B Voodoos and Convair F-102A Delta Dagger interceptors.

The Wisconsin Air National Guard 176th Fighter-Interceptor Squadron was federalized during the Korean War, receiving F-89Cs in February 1952-while on active duty. It was returned to state control in November 1952. Two squadrons of the Wisconsin Air National Guard, the 126th Fighter-Interceptor Squadron at General Mitchell Field, Milwaukee and the 176th Fighter-Interceptor Squadron at Truax Field, Madison were the first ANG units to be equipped with a mixture of F-89B/Cs in September 1954.
The Northrop F-89 Scorpion reached the end of the line of US military service in July 1969 when the Iowa Air National Guard 124th Fighter-Interceptor Squadron retired its last F-89Js.
