The Fleet Air Arm (FAA), known formerly as the Australian Navy Aviation Group, is the division of the Royal Australian Navy (RAN) responsible for the operation of aircraft. The FAA was founded in 1947 following the purchase of two aircraft carriers from the Royal Navy. FAA personnel fought in the Korean War (operating from the carrier HMAS Sydney) and the Vietnam War (attached to a Royal Australian Air Force squadron and a United States Army Aviation company), and participated in later conflicts and operations from host warships.
