During the Korean War, which began in June 1950, the Far East Air Forces (FEAF) were among the first units to respond to the invasion by North Korea, but quickly lost its main airbase at Kimpo, South Korea. Designated to provide close air support to the defenders of the Pusan pocket from bases in Japan, the FEAF also conducted a strategic bombing campaign against North Korea's war-making potential simultaneously. General Douglas MacArthur's landing at Inchon in September 1950 enabled the FEAF to return to Korea and develop bases from which they supported MacArthur's drive to the Korean-Chinese border.
