The Fleet Air Arm (FAA), known formally 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.
Initially operating only fixed-wing aircraft, helicopters were first acquired by the FAA in 1952, forming Australia's first helicopter squadron. Helicopter usage increased over time, particularly after 1982, when the carrier HMAS Melbourne was decommissioned and not replaced. In 2000, following the removal from service of the land-based Hawker Siddeley HS 748 aircraft, the FAA became an all-helicopter force, operating in the anti-submarine warfare and maritime support roles. As of 2018, the FAA consists of five active squadrons, operating four helicopter types and two types of UAVs.
As a Letterbox Hybrid cache, you will find a logbook AND a Stamp. The stamp is not a trade item but intended to stay within the cache. Use it to stamp your own notebook, and stamp the logbook with your own personal stamp, OR alternatively, simply date and sign the logbook as you would normally do at any other geocache. Again, the stamp and logbook remain in the letterbox for the next visitor to use.
