Next-Generation Adaptive Propulsion (NGAP)

Pratt & Whitney’s proposed adaptive engine for the U.S. Air Force’s Next Generation Air Dominance fighter has moved closer to the detailed design review stage.

A potential mandatory cut in addition to ongoing continuing resolutions have military officials blasting congressional inaction on Pentagon plans.

The company said its digitally designed engine has completed a digital preliminary design review.

Rather than proceeding with a new F-35 engine, the service is using remaining Adaptive Engine Transition Program funds for sixth-generation development.

The U.S. military has set up a new joint pathway aimed at bringing on nontraditional suppliers to try to grow the propulsion industrial base.

A yearslong campaign to define a new U.S. air superiority fighter will reach a climax when a development contact is awarded in 2024.
