United States Navy Naval Astronaut Naval Flight Officer
Criteria: The Naval Astronaut insignias are issued in a single degree to naval aviators and flight officers from the United States Marine Corps, United States Navy, and United States Coast Guard, with all three branches being trained in the same pipeline. All three branches also wear the same insignia which consists of a Naval Aviator insignia or Naval Flight Officer insignia with a centered gold astronaut device. However, the Coast Guard only issues the Naval Flight Officer version of the astronaut insignia under the name "Coast Guard Astronaut insignia."
