United States Navy Miniature Naval Aviation Observer - Flight Meteorologist Insignia
Criteria: The Naval Aviation Observer Badge was first created in 1922 and authorized to navigators and other support personnel on multi-person naval aircraft. The original badge was based on the design of the Naval Aviator badge, but with a single left-side wing and a circular "O" surmounting the foul anchor rather than a shield. In 1927 this insignia was superseded by a new device, identical to the Naval Aviator's wings but in silver rather than gold. This in turn was replaced in 1929 by a gold insignia with a center device of a silver anchor within a silver circle.
The Flight Meteorologist insignia is a military badge decoration of the United States Navy which is issued to officers of the Restricted Line who are commissioned as weather and meteorology specialists. To be issued the insignia, an officer must also have completed flight training to qualify as a Naval Aircrew Member. For Navy and Marine Corps aviation officers previously designated as Naval Aviation Observers, these officers were redesignated as Naval Flight Officers in 1966 and their insignia replaced by the current Naval Flight Officer insignia in the mid-1960s.
In the modern Navy, the Naval Aviation Observer insignia is occasionally issued under its original name but is jointly known as the Flight Meteorologist insignia.
