the creation of the Mach 2 J79, most engines had been designed essentially
independently of the aircraft they eventually powered. The J79 was the
first GE engine designed with the sophistication provided by already
developed and demonstrated components and advanced instrumentation techniques
for projecting test performance.
J79's first flight took place in Schenectady, New York in 1955. The
J79 was placed in a bomb bay of a J47-powered B-45 Tornado. The engine
was tested by lowering it from the bomb bay into the air stream. The
four J47s were shut down and the J79 powered the B-45.
J79 was first flown aboard the XF4D and later set a world altitude record
at 91,249 feet and a speed record of more than 1,400 miles per hour
in a F-104 Starfighter.
J79 was later selected to power the F-4 Phantom. At the time of its
introduction, the J79 was the most advanced turbojet ever designed.
To date, more than 2,500 engines are still in service and are projected
to continue through 2020.
