539th Fighter-Interceptor Squadron Wikipedia
The 539th Fighter Squadron was activated in October 1943 at Westover Field, Chicopee, Massachusetts in October 1943. Shortly after activation, the squadron moved to Seymour Johnson Field, Goldsboro, North Carolina to become part of the 402d Fighter Group where it operated under the Replacement Training Unit Program of the advanced phase of pilot training. In December 1943, the squadron again moved, this time to Bluethenthal Field, Wilmington, North Carolina, and was assigned to the 326th Fighter Group where it remained until disbanded in April 1944.
It was reactivated as part of the United States Air Force Air Defense Command. In January 1955 it received F-86D's and in August 1955 the unit designation was transferred to McGuire Air Force Base as the 539th Fighter Interceptor Squadron where it received F-86L's. In May 1959 the squadron transitioned to F-106A becoming the first squadron in the United States Air Force to be equipped with the F-106's.
On 22 October 1962, before President John F. Kennedy told Americans that missiles were in place in Cuba, the squadron dispersed one third of its force, equipped with nuclear tipped missiles to Olmsted Air Force Base at the start of the Cuban Missile Crisis. These planes returned to McGuire after the crisis.
