For the next two months, equipped with bombs, rockets and napalm, No. 77 Squadron supported UN troops retreating before the North Korean advance. To expedite turnaround times between missions, the Mustangs, which were still based at Iwakuni, often refuelled and rearmed at Taegu near the Pusan Perimeter, where UN forces made a last-ditch stand on the southern tip of Korea. One of the squadron's Dakotas regularly flew between Iwakuni and Taegu carrying ordnance and spare parts. According to the official history of the Air Force in 1946–71, the squadron's part in the victory at Pusan earned recognition "not only for the RAAF but also Australia at the highest political levels in the United States". During a visit to Japan in August 1950, Prime Minister Robert Menzies presented the Gloucester Cup to No. 77 Squadron as the RAAF's most proficient unit of the past year. That month, the squadron claimed thirty-five tanks, 212 other vehicles, eighteen railway engines or cars, and thirteen fuel or ammunition dumps destroyed.
