edit: I don't see USAF mentioned in this press release from Boeing
Pratt & Whitney’s PW4062 engine will be the standard production engine offering for all future 767 Tanker Programs, both domestic and international.
Pratt & Whitney’s engine, qualified for the 767 commercial series aircraft, was selected based on a best-value evaluation criteria, including engine performance, pricing considerations, management, and quality and schedule history. Pratt & Whitney has also been selected as the 767 Tanker engine provider based on their investment in the core tanker development program.
