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.
Military history of Australia
On 25 June 1950, the North Korean Army (KPA) crossed the border into South Korea and advanced for the capital Seoul, which fell in less than a week. North Korean forces continued toward the port of Pusan and two days later the United States offered its assistance to South Korea. In response the United Nations Security Council requested members to assist in repelling the North Korean attack. Australia initially contributed P-51 Mustang fighter-bomber aircraft from No. 77 Squadron RAAF and infantry from the 3rd Battalion, Royal Australian Regiment (3 RAR), both of which were stationed in Japan as part of the BCOF. In addition, it provided the majority of supply and support personnel to the British Commonwealth Forces Korea. The RAN frigate HMAS "Shoalhaven", and the destroyer HMAS "Bataan", were also committed. Later, an aircraft carrier strike group aboard was added to the force.
