Air Force Navigator/Observer Badge master, type 2

The Navigator Badge is a military qualification badge of the United States Armed Forces which was first created during the Second World War. The current USAF badge is designated by Air Force Instructions as the Navigator/Observer Badge and is issued to rated officers in both rating categories. In 2009, it was renamed as the Combat Systems Officer badge.
The original Navigator badge was issued by the U.S. Army Air Forces and consisted of an armillary sphere centered between two wings. The badge was similar to the Aviator Badge and the Aircrew Badge. On July 26, 1947, the U.S. Air Force became a separate Branch of Service in the U.S. armed forces. and in late 1951 the Aircraft Observer, Navigator, and Bombardier badges were replaced with a single design, with the Air Force shield centered between two wings.

The current USAF Navigator/Combat Systems Officer/Observer Badge is issued in three degrees: Basic, Senior, and Master. The degree of the Navigator/Combat Systems Officer/Observer Badge is determined by years of flying service in the Air Force and by logged hours of flight time or flying duty assignment time. The degrees are annotated by a star alone (senior) and a star and wreath (master) centered above the badge.
