The US Navy has selected Boeing to design, build and deliver its F/A-XX sixth-generation fighter under a multi-billion-dollar contract announced on 29 September. The aircraft is intended to replace the service’s F/A-18 Super Hornets.
Boeing said the programme will incorporate an open mission systems architecture and advanced mission systems, while extending the Navy’s operational reach and capacity. Technical specifications, development milestones and other programme details remain classified.
The award gives Boeing a second sixth-generation fighter programme, following its 2025 selection to develop the US Air Force’s F-47. The company will now pursue the two combat aircraft programmes in parallel.
Steve Parker, president and chief executive of Boeing Defense, Space & Security, said the company had planned and invested for concurrent development, including new facilities, technology and personnel.
Construction is continuing on Boeing’s secure manufacturing facility in St Louis, which the company says will support the design and production of multiple future aircraft. The announcement did not disclose an exact contract value, planned production quantities or an entry-into-service date for F/A-XX.
