Boeing Wins Navy F/A-XX Fighter Contract Worth Over $20 Billion

The US Navy has selected Boeing to build its next-generation carrier fighter, the F/A-XX, in a contract valued at more than $20 billion for the full-scale development phase. The announcement on 29 September 2026 ended a long public silence on the programme and a competition in which Boeing faced Northrop Grumman.

What the contract covers

The award funds development of a sixth-generation, manned carrier fighter that will begin replacing F/A-18E/F Super Hornets and EA-18G Growlers in the 2030s. According to The Aviationist, it is intended to offer about 25 per cent more range than the F-35C, along with electronic-warfare capability beyond that of the Growler.

The Navy also intends the aircraft to act as the “quarterback” of the carrier air wing, directing several Collaborative Combat Aircraft in contested airspace. Chief of Naval Operations Adm. Daryl Caudle has argued that the ability to operate existing airframes with impunity is fleeting, which is the central case for the new fighter.

Boeing’s double win

Boeing already holds the US Air Force’s F-47 contract, awarded in March 2025, so the company now manages both American sixth-generation fighters. Naval News reports that Boeing has invested billions in St. Louis, including a 1.1-million-square-foot expansion, to prepare for building both types in parallel. Breaking Defense described the result as a significant turnaround for Boeing’s defence business.

That concentration raises an obvious question about execution. Running two clean-sheet fighter developments at one site, while the company also builds the F/A-18 and other military products there, will test its engineering and production management. Analysts at Breaking Defense noted uncertainties about how the work will be handled, though the Navy has not detailed any additional measures.

A long road to selection

The programme’s requirements date to 2008, with a formal request for information issued in 2012. More recently funding became a political issue: Naval News notes that the administration proposed cutting the F/A-XX line to $76 million in its 2025 budget request, and Congress restored the money. The Navy has said it wants a fighter capable of operating alongside F-35s and Super Hornets for years.

If the programme follows the F-47’s pace, Naval News suggests a first flight could come around three years after contract award, which would place it near the end of the decade. The Navy has not confirmed that schedule, and the full-scale development phase does not by itself commit the service to a production quantity.

What to watch

Northrop Grumman, the losing bidder, has already pivoted to self-funded autonomy and drone work. The next visible milestones for Boeing are the build of the first test aircraft, the selection of the engine and mission-system suppliers, and the Navy’s plans for how many Collaborative Combat Aircraft the F/A-XX will direct from the carrier deck.
