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.

A B-17 with squadron code 2G

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

A B-24 with squadron code 2C, denoting the 838th Bombardment Squadron of the 487th Bombardment Group (tail Square P)

A B-17 with squadron code LL, denoting the 401st Bombardment Squadron of the 91st Bombardment Group (tail Triangle A)

A B-17 with squadron code VE, denoting the 532d Bombardment Squadron of the 381st Bombardment Group (tail Triangle L)

A B-17 with squadron code WF, denoting the 364th Bombardment Squadron of the 305th Bombardment Group (tail Triangle G; obscured in photo)
