Australia in the Korean War
No. 77 Squadron converted to P-51D Mustang fighters before arriving in Japan in February 1946 to participate in the British Commonwealth Occupation Force. Occupation duties proved uneventful, and No. 77 Squadron was preparing to leave Japan for Australia when the Korean War broke out in June 1950. 77 Sqn was immediately dispatched to Korea, where they became the first UN air unit to enter the war, primarily in ground support, combat air patrol, and escort missions.
History of Australian naval aviation
"Sydney" was the only non-US, non-UK aircraft carrier to be involved in the Korean War. The operation of a United States helicopter aboard "Sydney" during the war prompted the development of helicopter aviation in the Australian military. The RAN's second aircraft carrier, , had encountered delays while upgrading to the latest technology, and the British aircraft carrier was loaned to the RAN from 1952 until 1955, when "Melbourne" was commissioned. "Sydney" was decommissioned and converted into a troop transport during the late 1950s, and the obsolescence of "Melbourne"s British-designed aircraft saw her reduced to helicopter operations until the mid-1960s, when new aircraft were purchased from the United States. "Melbourne" did not participate in the Vietnam War, although RAN pilots were used to support RAAF and United States Army helicopter units.
