The squadron was activated in April 1943 as the 636th Bombardment Squadron at Key Field, Mississippi, as one of the original squadrons of the 408th Bombardment Group.[1][2] In August, along with other Army Air Forces (AAF) single engine dive bomber units, it became a fighter-bomber unit, and was redesignated as the 518th Fighter-Bomber Squadron.[1] The squadron did not receive aircraft to begin training until October, after it had moved to Drew Field, Florida.[2] It served as an operational training unit with various aircraft, providing cadres to "satellite groups" and as a replacement training unit, training individual pilots.[1][3]
However, the AAF was finding that standard military units, 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 AAF base was organized into a separate numbered unit.[4] In this reorganization the squadron was disbanded in 1944 as the AAF converted to the AAF Base Unit system.[1] It was replaced, along with other units at Woodward Army Air Field, by the 267th AAF Base Unit (Combat Crew Training Station, Fighter) in a reorganization of the AAF in which all units not programmed for deployment overseas were replaced by AAF Base Units to free up manpower for assignment overseas.[5]
