Description
This insignia was introduced in 1943. The blue and white gloss insignia was referred to as the "star and bar" and was standard on all planes in the U.S. military in WWII. It was painted under both wings to help ground troops avoid friendly fire. The insignia in this photo is located on a P-47 that has been decorated as "Five by Five", flown by Colonel Joseph Laughlin in World War II.
