Origins of the Cold War
Australia's entry into the Cold War came in 1950, when it rushed combat air and sea forces into the Korean War, two days after the Americans did. The Australian Prime Minister received a hero's welcome in Washington. The ANZUS military alliance with New Zealand and the United States was signed in July 1951; it was a plan for consultation and did not involve military planning like NATO. Public opinion in Australia was intensely hostile to Japan after its wartime atrocities, but Japan was now an ally in the Cold War, so Australia's accepted the very generous soft peace treaty with Japan in 1951. Instead of worrying about a resurgent Japan, Australia now worried more about a possible Chinese threat.
No. 491 Squadron RAAF
No. 491 (Maintenance) Squadron was a Royal Australian Air Force (RAAF) squadron that operated during the Korean War and its immediate aftermath. It was unusual in that it was never based in Australia, being formed and dissolved in Japan. The squadron was established in October 1950 as part of No. 91 (Composite) Wing, which administered all RAAF units deployed as part of Australia's involvement in the Korean War. Apart from No. 491 Squadron, these included No. 77 (Fighter) Squadron, No. 30 Communications Unit (redesignated No. 30 Transport Unit in 1951 and No. 36 (Transport) Squadron in 1953), and No. 391 (Base) Squadron. No. 77 Squadron was based on the Korean peninsula, while No. 491 Squadron and other components were headquartered at Iwakuni, Japan. The maintenance squadron was responsible for the upkeep of all aircraft at Iwakuni, and a section was attached to No. 77 Squadron in South Korea to assist with day-to-day servicing. was disbanded in December 1954.
