The 538th Fighter-Interceptor Squadron is an inactive unit of United States Air Force. It was last assigned to the Spokane Air Defense Sector at Larson Air Force Base, Washington.

The squadron was first activated during World War II as the 538th Fighter Squadron. It briefly served as a Republic P-47 Thunderbolt replacement unit before being disbanded in a major reorganization of Army Air Forces training units in the spring of 1944. The squadron was again activated in 1955 as an interceptor unit of Air Defense Command, defending the northwestern United States. It was inactivated in 1960, when the Air Force transferred its Lockheed F-104 Starfighters to the Air National Guard.

The squadron was first activated by I Fighter Command in October 1943 at Westover Field, Massachusetts as one of the three original squadrons of the 402d Fighter Group.[1][2][3][4] Less than two weeks later, the squadron moved with its group headquarters to Seymour Johnson Field, North Carolina.[1][2] At Seymour Johnson, the 538th and 539th Fighter Squadrons of the 402d Group were reassigned to the 326th Fighter Group, which transferred two of its squadrons to the 402d.[3][5]

The 326th Group was a Replacement Training Unit for Republic P-47 Thunderbolt pilots. Replacement Training Units were oversized units that trained individual pilots.[6] Like most such units, the 326th prepared to conduct a split operation and the 538th and 539th Squadrons moved to Bluethenthal Field, North Carolina,[1][3] while group headquarters and its other two squadrons remained at Seymour Johnson.[5] The squadron finally received its Thunderbolts in early 1944 and began operations.[1] However, the Army Air Forces was finding that standard military units, based on relatively inflexible tables of organization, were not proving to be well adapted to the training mission. Accordingly, it adopted a more functional system in which each base was organized into a separate numbered unit.[7] The 538th was disbanded[1] and its mission, personnel and equipment were transferred to the 124th AAF Base Unit (Fighter) and combined with other units at Bluethenthal.

In the summer of 1955 Air Defense Command (ADC) implemented Project Arrow, which was designed to bring back on the active list the fighter units which had compiled memorable records in the two world wars. Project Arrow also reunited fighter squadrons with their traditional headquarters.[8] As a result, the 323d Fighter-Interceptor Squadron at Larson Air Force Base, Washington moved to Truax Field, Wisconsin to joint the 327th Fighter Group there.[9][10] The 538th was reconstituted as the 538th Fighter-Interceptor Squadron and activated at Larson to take over the mission, personnel and equipment of the departing 323d Squadron.[1]

The squadron also took over the 323d's radar equipped and Mighty Mouse rocket armed North American F-86D Sabres. By the fall of 1957, the 538th had re-equipped with the F-86L Sabre, which was equipped with data link for interception control through the Semi-Automatic Ground Environment (SAGE) system. Squadron experience with the F-86L was short-lived however, as the squadron began transition into the Lockheed F-104A Starfighter about June 1958.[11]

The 538th was the fourth ADC squadron to equip with the Starfighter.[citation needed] The squadron also received the two-seat, dual-control, combat trainer F-104B. The performance of the F-104B was almost identical to that of the F-104A, but its smaller internal fuel capacity reduced its effective range considerably. However, ADC did not believe the F-104A was well suited for service as an interceptor. Its short range and lack of all-weather capability made it incapable of integrating into the SAGE system. All ADC F-104As, including those of the 538th, were transferred to the Air National Guard and the squadron was inactivated in July 1960.[1][12][note 3]
