1950 Jun: Korean War—Into the Jet Age: 77 Squadron’s Mustangs in Korea

Overview

In June 1950 No. 77 Squadron of the Royal Australian Air Force, based at Iwakuni in Japan as part of the British Commonwealth Occupation Force, was abruptly committed to combat following North Korea’s invasion of the South. Flying P-51 Mustangs, the squadron commenced operations on 30 June, conducting armed reconnaissance and close air support in support of United Nations forces. These initial piston-engined operations proved operationally decisive in slowing enemy advances, protecting evacuations, and stabilising the air situation, while simultaneously preparing the RAAF for rapid transition into jet warfare.

Glossary of terms

• British Commonwealth Occupation Force: Allied post-war force responsible for the occupation and demilitarisation of Japan after 1945.

• Armed reconnaissance: Offensive air operations combining reconnaissance with immediate attack on targets of opportunity.

• Close air support: Air action against hostile targets in direct support of ground forces, requiring close coordination.

• Forward air control: The direction of air strikes from forward positions to ensure accuracy and prevent fratricide.

• P-51 Mustang: Long-range single-seat fighter optimised for endurance, ground attack, and tactical flexibility.

• United Nations Command: Multinational command structure established to direct coalition forces in Korea.

Key points

• Strategic shock and rapid commitment: The North Korean invasion confronted the RAAF with an immediate operational requirement. Official histories emphasise that No. 77 Squadron moved from occupation routine to combat readiness within days, illustrating institutional flexibility rather than pre-planned expeditionary posture.

• Operational value of the Mustang: Despite the emergence of jet fighters, the P-51 Mustang’s range, loiter time, and weapons load proved indispensable. Its ability to remain over the battlefield enabled sustained pressure on advancing enemy formations during the critical opening phase.

• Early missions and tempo: Commencing combat on 30 June 1950, the squadron flew multiple daily sorties, striking transport, armour, and troop concentrations. These actions materially disrupted North Korean momentum during the advance towards Pusan.

• Protection of evacuations: Mustangs provided air cover for the evacuation of civilians and military personnel from forward airfields and ports. Official accounts note that this air presence reduced losses and preserved coalition freedom of manoeuvre.

• Integration with allied forces: Operating under United States Fifth Air Force control, No. 77 Squadron rapidly adopted American procedures, communications, and logistics systems, setting a pattern for future coalition air operations.

• Logistical adaptation: Sustained Mustang operations exposed supply vulnerabilities in spares, ammunition, and maintenance manpower. The RAAF’s response refined expeditionary logistics practices that later supported jet operations.

• Tactical lessons: Ground fire losses highlighted the vulnerability of piston aircraft in low-level attack roles, reinforcing the need for improved tactics, coordination with ground forces, and eventual transition to jets for contested airspace.

• Training and professionalism: Squadron aircrew drew heavily on Second World War experience, but Korea demanded tighter control, faster decision-making, and closer joint integration, accelerating post-war professional development.

• Bridge to the jet age: While Mustangs carried the initial burden, their employment informed the subsequent conversion to Gloster Meteors. Official histories describe this period as a practical laboratory for jet-era doctrine.

• Strategic significance for Australia: The commitment of No. 77 Squadron marked Australia’s first major Cold War combat air operation, embedding the RAAF within United Nations and United States-led air power structures.
