The F-86 prototype was first flown on October 1,1947, and in 1949, by which time it had gained the name Saber, the new fighter began to enter service with the USAF. The F-86 saw considerable service in the Korean War where, despite marginally inferior performance to the much vaunted Mikoyan-Gurevich MiG-15, they were able to gain superiority over these aircraft thanks to the superior training and experience of their pilots. Subsequently, in addition to serving with the air arms of NATO and British Commonwealth countries, the F-86 Saber was supplied to many other countries throughout the world. The F-86D Saber used one 7,500-lb. thrust afterburning General Electric J47-GE-17B or -33 turbojet, with a maximum speed at sea level of 707 mph, a service ceiling of 54,600 feet, and a range of 835 miles. Airplane armament was twenty-four 2.75-inch air-to-air rocket projectiles.
