# List of USAAF squadron codes

This is an incomplete list of squadron codes used by United States Army Air Forces (USAAF) aircraft operating in Europe during World War II.

## Squadron codes

For each squadron code—painted on the plane's fuselage—the associated bombardment squadron (BS) is listed, along with the squadron's bombardment group (BG). Most commonly, a group would have four squadrons. Also listed is the group's tail code—the noted letter would appear inside the geometric shape (for example, ▲J means the letter J would appear inside a triangle). Some squadrons and groups also used specific color bands on the wings or empennage of their aircraft; such colorings are not presented here.
Notes:
* 381st BG: some squadrons were assigned more than one code
* 482d BG: Pathfinder squadrons with variable use of codes
* Some squadrons used colors rather than characters; these are listed below
