The U.S. Air Force awarded contracts of nearly $1 billion each to GE Aviation and Pratt & Whitney to further develop a next-generation military jet engine under the Adaptive Engine Transition Program (AETP). The service envisions the new engine powering a sixth-generation fighter and potentially an upgraded F-35 Lightning II.
