The squadron was first activated as the 619th Bombardment Squadron in 1943. It was one of the four squadrons of the 477th Bombardment Group, the first (and only) bombardment group in the united States Army Air Forces to included black pilots.

The squadron was inactivated in 1945 when the 477th became a composite group that included one bombardment and one fighter squadron.
