515th Strategic Fighter Squadron

The 515th Strategic Fighter Squadron is an inactive United States Air Force unit. Its last assignment was with the 407th Strategic Fighter Wing stationed at Great Falls Air Force Base, Montana, where it was inactivated on 1 July 1957.

The squadron was first activated in March 1943 as the 632d Bombardment Squadron and equipped with light ground attack aircraft. In July 1943, the air echelon of the squadron deployed to the Aleutian Islands to defend against the Japanese attacks there. It returned to the United States the following month and was redesignated the 515th Fighter-Bomber Squadron, while continuing to train for combat with the same mission. It became a Replacement Training Unit, but was disbanded in the spring of 1944 in a general reorganization of Army Air Forces training units.

The squadron was reactivated in 1953 as part of Strategic Air Command (SAC), flying escort fighters and a few air reconnaissance aircraft. In 1954, the squadron deployed to Japan and provided air defense for the northern part of the islands. It supported SAC bombardment operations until inactivating.

World War II
The squadron was activated in late March 1943 at Drew Field, Florida as the 632d Bombardment Squadron, one of the four original squadrons of the 407th Bombardment Group. The squadron was equipped with Douglas A-24 Banshees. In July, the squadron's air echelon deployed to Amchitka Army Air Field, Alaska to reinforce Eleventh Air Force in Operation Cottage, an attack on Kiska, the last Japanese outpost in the Aleutian Islands. The first combat sorties by elements of the 407th Group were flown on 4 August 1943, in an attack against antiaircraft artillery batteries in the main Japanese camp. The returning crews reported only meager small arms and light automatic weapons fire. As it turned out, the Japanese had decided to evacuate Kiska, leaving the United States in control of the Aleutians, and the squadron was returned to its training base in Florida, under its new name, the 515th Fighter-Bomber Squadron.

After arriving in Florida, the squadron resumed training for deployment overseas, but was soon assigned the mission of acting as a Replacement Training Unit (RTU). The RTU was an oversized unit organized to provide final training for individual pilots or aircrews. Initially the squadron flew a mix of the A-36 Apache and early model P-51 versions of the Mustang fighter, but by the end of the year had become a Republic P-47 Thunderbolt training unit at Galveston Army Air Field, Texas.

However, the Army Air Forces were finding that standard military units like the 515th, which were manned based on relatively inflexible tables of organization were not proving well adapted to the training mission. Accordingly, it adopted a more functional system in which each base was organized into a separate numbered unit. The 515th, along with other elements of the 407th Group and supporting units at Galveston, was disbanded and replaced by the 269th AAF Base Unit (Replacement Training Unit, Fighter).

Strategic fighter operations
The squadron was reconstituted in December 1953 at Great Falls Air Force Base, Montana as the 515th Strategic Fighter Squadron, although it was initially undermanned and did not begin operational training with its Republic F-84 Thunderjets until June 1954. From August until November 1954, the squadron deployed to Misawa Air Base, Japan and provided air defense for the northern Japanese islands. Its parent 407th Strategic Fighter Wing was the last of Strategic Air Command's fighter wings to rotate through Misawa during and immediately after the Korean War. The squadron left its F-84G's at Misawa and re-equipped with F-84F Thunderstreak swept-wing aircraft on return to Montana. It also operated a few RF-84F reconnaissance versions of the Thunderstreak. In July 1957, Strategic Air Command transferred its fighter aircraft to Tactical Air Command and the squadron was inactivated along with the rest of the 407th Wing.
