This was to be the RAAF's largest aerial engagement during the Korean War and Australian pilots performed admirably, despite their Meteors having inferior manoeuvrability to the Soviet-built MiGs. They managed to score the RAAF's first victories of the Korean War, losing three Meteors in the action with two pilots captured and one missing presumed killed. Accounts naturally vary, with the Australians claiming at least 10 MiGs splashed, but Chinese and North Korean sources stated it was only one. Two MiG kills were later confirmed. As a result of this action, 77 Squadron's Meteors were considered inadequate for aerial defence and re-roled to a ground attack role for the remainder of the war.
