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. 91 Wing RAAF
When the Korean War broke out on 25 June 1950, No. 77 (Fighter) Squadron of the Royal Australian Air Force (RAAF) was based at Iwakuni, Japan. For the previous four years, equipped mainly with North American P-51 Mustangs, it had served with the British Commonwealth Air Group, the air component of the British Commonwealth Occupation Force (BCOF), initially as part of No. 81 Wing RAAF. No. 81 Wing was disbanded in November 1948, leaving No. 77 Squadron as Australia's sole air unit in Japan. It was now the largest squadron in the RAAF, comprising 299 officers and men, forty Mustangs, three CAC Wirraways, two Douglas C-47 Dakotas and two Austers. The squadron was preparing to return to Australia when it was placed on standby for action over Korea; it began flying missions as part of the United Nations (UN) peacekeeping force a week later. No. 77 Squadron's commanding officer, Wing Commander Lou Spence, was killed in action on 9 September 1950, and Air Commodore Alan Charlesworth, Chief of Staff at BCOF, temporarily took charge at Iwakuni, pending the formation of an overarching organisation for support and administration at the base. Squadron Leader Dick Cresswell arrived on 17 September to assume command of No. 77 Squadron.
