Boeing Wins Navy's F/A-XX Contract, Now Sole Builder of America's Sixth-Generation Fighters

The Pentagon announced Tuesday, September 29, that Boeing has been selected to build the Navy's sixth-generation carrier-based fighter, the F/A-XX, beating out Northrop Grumman for the deal, according to Breaking Defense, Defense News and the Pentagon's own release.

The contract is worth more than $20 billion for the full-scale development phase, per the Department of War's announcement. That money buys multiple test aircraft for ground testing, airworthiness evaluations, and systems and weapons integration, not a finished production line of combat-ready jets. First flight isn't expected until sometime in the 2030s, the Pentagon said.

This is Boeing's second sixth-gen fighter win in under two years. Boeing beat Lockheed Martin in March 2025 for the Air Force's F-47 program. With F/A-XX now added to the tally, Boeing is the sole American manufacturer holding contracts to build sixth-generation fighters for either service. Lockheed keeps building the fifth-gen F-35, but it's shut out of next-gen fighter work entirely. Northrop Grumman, which lost both competitions, is shut out too.

What the Navy is buying

Michael P. Duffey, under secretary for acquisition and sustainment, called the F/A-XX 'a critical pillar in our commitment to maintaining peace through strength' that will 'dominate contested airspace, extend operational reach, and deliver a decisive combat advantage for the warfighter,' according to the Pentagon statement carried by Breaking Defense, Defense News and Anadolu Agency.

Acting Navy Secretary Hung Cao said the jet represents 'a generational leap in air superiority' for 'the world's best aviators.' Boeing Defense CEO Steve Parker called the selection 'an honor' and said the company invested specifically to run two sixth-gen fighter programs in parallel: 'Delivering two advanced fighters in parallel was always our plan, and we invested accordingly,' Parker said, per Fox News and Free Malaysia Today.

The F/A-XX is designed to fly alongside the F-35C and eventually replace the Navy's aging F/A-18E/F Super Hornets and EA-18G Growlers starting in the 2030s, according to defence-industry.eu. It's built to work with both manned aircraft and unmanned Collaborative Combat Aircraft, extending how far carrier air wings can strike without risking pilots closer to enemy defenses.

Admiral Daryl Caudle, the chief of naval operations, told a Senate panel in May 2026 that delay carried real risk, warning that 'failure to field next-generation carrier aviation capability on schedule will introduce risk to air superiority, strike reach and the long-term viability of carrier-based operations in contested environments,' according to Free Malaysia Today.

A bumpy road to get here

This wasn't a clean process. Breaking Defense reported that after the Air Force awarded Boeing the F-47 contract in 2025, F/A-XX was expected to follow quickly, but the program stalled. In July 2025, the White House reportedly warned that pushing forward with the Navy fighter too fast could jeopardize the F-47 program's success. It took over a year from that point for the Navy to make its call.

Northrop Grumman, in a statement carried by Breaking Defense and Free Malaysia Today, said it 'offered a highly survivable, digitally advanced sixth-generation fighter to the U.S. Navy' and is waiting on 'additional information' about why it lost.

The competition concern

Handing one contractor both of America's sixth-generation fighter programs raises questions about competition. Defense analysts have long argued that competition between contractors keeps costs down and gives the Pentagon leverage if a program runs into trouble. With Lockheed and Northrop both locked out of next-gen fighter work, Boeing effectively becomes the only game in town for the foreseeable future on this technology.

The concern is sharpened by Boeing's track record on other government programs, including years of cost overruns and delays on the KC-46 tanker. If F/A-XX hits similar problems, the Navy doesn't have another sixth-gen manufacturer standing by to pick up the slack.

The counterpoint, made implicitly by the Pentagon's own selection, is that Boeing beat Northrop on the merits in a competitive bid process, twice, and the Navy chose the design and team it judged best equipped to deliver. Parker's statement about deliberately investing to run two programs in parallel, including a new secure manufacturing buildout in St. Louis, according to defence-industry.eu, is Boeing's answer to the capacity question directly.

Markets reacted modestly. Boeing shares rose 2.4% in after-hours trading following the announcement, while Northrop Grumman shares fell 3.6%, according to Free Malaysia Today.

What isn't yet public is the technical details of the F/A-XX design, which Boeing says remain classified under U.S. national security and export laws. Execution is the test now: whether Boeing can deliver a Navy carrier fighter on schedule while simultaneously running the Air Force's F-47 program, with first flight for either aircraft still years away.
