The Pratt & Whitney PW2000, also known by the military designation F117 and initially referred to as the JT10D, is a series of high-bypass turbofan aircraft engines with a thrust range from 37,000 to 43,000 lbf (160 to 190 kN). Built by Pratt & Whitney, they were designed for the Boeing 757.

Pratt & Whitney's PW2000 engine covers the mid-thrust range from 37,000 pounds to 43,000 pounds. The PW2000 powers all models of the twin-engine Boeing 757, and is the exclusive power as the F117 for the four-engine C-17 Globemaster III military transport. The PW2040 model also powers the U.S. Air Force’s C-32A, the military version of the 757.

The PW2000 was the first to offer Full Authority Digital Electronic Control (FADEC), an electric engine control system. The PW2000 also uses new materials, new airfoil profiles, new combustor configurations and other special technological features. There are 429 757s powered by the PW2000 series engines. Most of these, 289, are equipped with ...
