Designed during WWII and built in 180 days the F-80 did see some service in Italy in the final days of WWII. Post war many were stationed both in Europe and in Japan. Those in Japan were the first to answer the call when the North Koreans invaded South Korea.
The F-80 compiled a strong record in the Korean conflict. The aircraft is credited with shooting down 17 enemy aircraft, using in excess of 80,000 air to ground rockets and dropping over 33,000 tons of bombs during almost 90,000 combat sorties. A most admirable record for any aircraft. They served throughout the conflict and were the first US jet to engage in jet to jet combat.
