The US Navy’s selection of Boeing for the F/A-XX sixth-generation fighter programme will establish a new aircraft platform for future naval aviation, with its open mission systems architecture expected to have implications for maintenance, upgrades and lifecycle support.
The US Navy has awarded Boeing a multi-billion-dollar contract to develop and produce the F/A-XX, the next-generation carrier-based fighter intended to replace the Navy’s F/A-18 Super Hornet fleet. The Navy is developing the programme under its Next Generation Air Dominance effort.
For the MRO sector, the significance of the programme extends beyond aircraft production. The F/A-XX is being designed around an open mission systems architecture, creating a framework intended to accommodate evolving mission capabilities and technologies over the aircraft’s service life.
Open architecture could support future upgrades
The use of open systems architecture is particularly relevant to long-term aircraft sustainment because future upgrades can require integration of new software, sensors, mission systems, and other equipment without redesigning the entire aircraft architecture.
However, the Navy and Boeing have not released detailed information on the F/A-XX’s maintenance architecture, planned support model, maintenance intervals or specific sustainment technologies. Those elements remain subject to programme development and classified technical information.
The programme will therefore establish a new maintenance and support ecosystem as the aircraft moves from development into testing and, ultimately, operational service.
The US Navy has said the programme will involve multiple test aircraft for ground, airworthiness, systems and weapons-integration testing, creating an initial requirement for specialised test, inspection and technical-support capabilities as development progresses.
Manufacturing investment supports lifecycle capability
Boeing is continuing construction of a secure manufacturing facility in St. Louis, which the company says will form part of an all-digital aerospace design and manufacturing system.
For MRO and lifecycle support, the move toward digitally enabled production can provide a foundation for maintaining configuration data and supporting the complex systems expected on a sixth-generation combat aircraft.
Boeing has also highlighted investment in technology and its workforce alongside its manufacturing infrastructure.
“It’s an honor to be selected to produce the Navy’s first sixth-generation platform. Backed by decades of work, bolstered by game-changing innovations and solidified by the investments we’ve made in new facilities uniquely suited to build multiple products with next-generation capabilities, our dedicated and talented team is ready to execute this critical program,” said Steve Parker, president and chief executive officer, Boeing Defense, Space & Security.

F/A-XX will introduce a new sustainment challenge
The F/A-XX is expected to enter service in the 2030s, with its development introducing a new generation of aircraft systems into the Navy’s carrier aviation fleet.
For MRO providers and defence sustainment organisations, the programme will eventually create requirements spanning component repair, technical data, software and mission-system updates, specialist tooling, inspection equipment and workforce training.
The Navy’s broader acquisition framework also recognises the importance of lifecycle technical data, software rights and the development of maintenance capabilities for major defence programmes.
Boeing’s selection for F/A-XX follows its 2025 selection for the US Air Force’s F-47 sixth-generation fighter programme, giving the company two next-generation combat-aircraft programmes to develop in parallel.
