The Battle of Sunchon was an air battle fought near the city of Sunchon, North Korea on 1 December 1951, during the Korean War. Up to 14 Gloster Meteor jets of the RAAF's No. 77 Squadron were attacked by at least 20 MiG-15s of the Soviet Union's 176th Guards Fighter Aviation Regiment (176 GIAP). The MiGs carried Chinese air force markings, as the USSR was not officially a combatant in the Korean War. Its experience in the battle led to No. 77 Squadron's being redeployed to ground attack duties.
