After WWII it appeared that the North American P-51Dí«í´s days in front line use were limited because of the advent of the jet age. The conflict in Korea brought the aircraft out of reserve and back into action but as the F-51D. When the P for pursuit prefix was dropped in favor of the F for fighter prefix, hundreds of Mustangs were so renamed. However, it was as a fighter-bomber that the F-51 was to make a name for itself. It wasní«í´t the skies over Europe, but the ground of the Korean peninsula that saw the most activity for the F-51. Too small to house the kind of airfields needed by jets, the Mustang was able to take off, drop its ordnance on an enemy only a few miles away and return for more. Often times Mustangs were flying four or five or more sorties a day.
