F100-PW-100 - Full power

EGLIN AIR FORCE BASE, Fla. (AFPN)—An F100-PW-100 engine runs at full afterburner in the 33rd Maintenance Squadron’s test cell here. The engine, for an F-15 Eagle, passed all tests and became a milestone for the propulsion flight as the 40th spare war-ready engine. Of the 167 total engines the 33rd Fighter Wing has, 59 are earmarked as spares. (U.S Air Force photo by Staff Sgt. Robert Zoellner)
