Next Generation Adaptive Propulsion - RTX's Pratt & Whitney

Pratt & Whitney has critically evaluated its Next-Generation Adaptive Propulsion (NGAP) offering in collaboration with the U.S. Air Force. This evaluation has brought the program one step closer to completing its detailed design review. The team is now focused on carrying out ground testing of its NGAP prototype, named XA103, which is expected to take place in the late 2020s.

"We are embracing digital transformation with NGAP and changing the customer experience through the entire development process to rapidly and efficiently deliver these advanced adaptive engines," said Jill Albertelli, president of Pratt & Whitney's Military Engines business. "This technology is critical to maintaining air superiority, which is why Pratt & Whitney has made significant investments in research and development and advanced manufacturing. Continued government funding for sixth-generation propulsion development must remain a high priority to support critical platform milestones and warfighter readiness."

The engine will enhance performance, enabling future air dominance capabilities, necessary for the U.S. Air Force to achieve air superiority and deter pacing challenges.

NGAP technologies will provide advanced survivability, fuel efficiency, and robust power and thermal management. These are necessary to enable the required range, weapon and sensor capability, and persistence future air dominance platforms will require to meet evolving operational needs.
