The F/A-XX contract covers full-scale development and multiple test aircraft for ground, airworthiness, systems and weapons integration testing. The department said the platform will begin augmenting and eventually replacing F/A-18E/F Super Hornets and EA-18G Growlers in the 2030s, while operating alongside the F-35C.
The fighter is intended to extend carrier-based operational reach and operate with crewed and uncrewed aircraft, including Collaborative Combat Aircraft. Boeing said the program will incorporate open mission systems architecture and advanced mission systems, although technical and program details remain classified.
“F/A-XX will dominate contested airspace, extend operational reach, and deliver a decisive combat advantage for the warfighter,” said Michael P. Duffey, Under Secretary of War for Acquisition and Sustainment. Acting Navy Secretary Hung Cao described the award as “a new era for the U.S. Navy.”
“Delivering two advanced fighters in parallel was always our plan, and we invested accordingly,” said Steve Parker, president and chief executive officer of Boeing Defense, Space & Security. “We are ready and able to build multiple concurrent future combat aircraft franchise programs.”
Boeing said construction continues on its secure manufacturing facility in St. Louis as part of its digital aerospace design and manufacturing system. “Investment in facilities is just one part of the story; we’re also investing in technology and people so that we can deliver for our customers,” Parker added.
