With the outbreak of the Korean War in June 1950, the 9th was one of the first USAF squadrons dispatched to Korea from Japan, initially operating propeller-driven F-51Ds to cover the evacuation of civilians from Kimpo and Suwon. Next, it flew close air support missions to help slow the advancing North Korean armies. Later, it turned to the interdiction of enemy troops, supplies and communications from Misawa. However its short-range F-80Cs meant that the 49th had to move to South Korea in order for them to be effective.
