The F100 family of fighter engines evolved from Pratt & Whitney's tradition of dependable engines. The first F100 entered service in 1974.
More than 6,400 F100s, in the air forces of the United States and 17 other nations, have accumulated more than 14 million engine flight hours.
The F100-PW-220 is the successor to the F100-PW-100 that powers the twin-engine Boeing F-15 and single-engine Lockheed Martin F-16 fighters.
