Under research and development contracts with DARPA, Boeing and Lockheed Martin designed two X-planes as risk reduction for the Next Generation Air Dominance (NGAD) Platform.
These aircraft first flew in 2019 and 2022, logging several hundred hours each.
As reflected in the statement from Chief of Staff of the Air Force Gen. David Allvin: “For the past five years, the X-planes for this aircraft have been quietly laying the foundation for the F-47 — flying hundreds of hours, testing cutting-edge concepts, and proving that we can push the envelope of technology with confidence.”
DARPA’s involvement began with its Air Dominance Initiative study in 2014, which resulted in the agency’s Aerospace Innovation Initiative. “It is often only in future decades when DARPA’s disruptive impact can be unveiled – today, we’re proud to be able to share the 10-year DARPA research arc that has culminated in the F-47 program, defining the next era of American air dominance," said DARPA Acting Director Rob McHenry.
