USAF: Boeing commercial‑tech upgrades to Pratt & Whitney F117 avert re‑engining of 222 C‑17s
The U.S. Air Force says Boeing’s application of commercial technologies to upgrade Pratt & Whitney’s F117 engines will eliminate the need to re‑engine the service’s 222 C‑17 Globemaster III aircraft. The approach aims to deliver capability and sustainment improvements without a full engine replacement program.
