Pratt & Whitney F100

The F100 was designed for the F-15 Eagle and first flew on that aircraft in 1972. The F100 had developmental problems when it was first introduced but today is one of the most reliable fighter engines in the world. Even the hottest parts have a 4,300 hour inspection interval, equivalent to nine years of fighter operation.
