Boeing Wins $20 Billion U.S. Navy Contract to Build Sixth-Generation F/A-XX Fighter

Writer Published Updated 0 comments

Why this matters: Boeing now holds both of America's crewed sixth-generation fighter programs, a position that will shape U.S. military aviation spending for decades.

September 30, 2026 — Boeing has been selected to build the U.S. Navy's next-generation stealth fighter, the Pentagon announced on Tuesday, awarding the company a development contract valued at more than $20 billion to develop the carrier-based F/A-XX jet. The decision ends months of delay over the program's future.

Editor's Highlight: By winning the Navy's F/A-XX a year after landing the Air Force's F-47, Boeing becomes the sole builder of crewed sixth-generation fighters in the United States, locking its rivals out of the next era of combat aircraft.

What the Contract Covers

The Pentagon said Boeing was selected over rival Northrop Grumman for the Engineering and Manufacturing Development phase of the F/A-XX program. The contract funds several test aircraft for ground, airworthiness, systems, and weapons integration testing.

Newsroom Focus: The more than $20 billion figure covers development only. As production ramps up, the program's lifetime value could reach hundreds of billions of dollars, according to Reuters.

A Back-to-Back Win for Boeing

The F/A-XX award is Boeing's second marquee sixth-generation win in consecutive years. In March 2025, the company was selected to build the Air Force's F-47 stealth fighter, making Boeing the sole U.S. builder of crewed sixth-generation fighters. Rivals Northrop Grumman and Lockheed Martin are now shut out of the next-generation fighter market for years.

The turnaround is striking. Before the F-47 and F/A-XX wins, Boeing had largely exited the fighter business, said Jeremiah Gertler, an expert at the Center for Strategic and International Studies.

Steve Parker, president and CEO of Boeing Defense, Space & Security, said the company has invested in new facilities "uniquely suited to build multiple products with next-generation capabilities," and that the team "is ready to execute this critical program."

How the Race Was Won

Boeing entered the competition as a strong contender, Reuters reported, because of its long history building carrier-based fighters for the Navy, including the F/A-18E/F Super Hornet that the new jet is designed to replace. That pedigree helped offset defense officials' questions about whether Boeing could field enough engineers and suppliers to execute two sixth-generation fighters at once.

Lockheed Martin had been eliminated from the competition in March 2025, leaving Boeing and Northrop Grumman as the finalists.

Analysis Note: The program nearly died. Some Pentagon officials had sought to delay it by up to three years, citing engineering and supply-chain capacity concerns, before Congress intervened with $750 million earmarked in the 2025 tax-cut and spending law and another $1.4 billion in fiscal 2026, according to Reuters.

What the F/A-XX Is Meant to Do

The F/A-XX will augment and eventually replace the F/A-18E/F Super Hornet and the EA-18G Growler, an electronic-attack variant, beginning in the 2030s, flying alongside the F-35C and controlling Collaborative Combat Aircraft (CCA), the uncrewed wingman drones the Navy is building for its future carrier air wing.

  • Advanced stealth: new low-observable characteristics expected.
  • Greater reach: improved range and endurance for Pacific operations.
  • Team operations: integration with uncrewed aircraft and carrier air defense systems.

The Navy still plans to buy more than 270 F-35C jets from Lockheed Martin, which will fly alongside the F/A-XX. The Navy also released a first official rendering of the winning design on Tuesday.

Michael Duffey, the Pentagon's chief weapons buyer, called the jet "a crucial, non-negotiable investment in America's national security and long-term air combat capabilities."

St. Louis Stands to Gain

The award is a major boost for Boeing's fighter production operations in St. Louis, Missouri, where the F/A-18E/F Super Hornet and EA-18G Growler lines are winding down. The same day it won, Boeing received a separate Navy order worth about $16.7 million to plan the shutdown of those legacy lines.

Missouri lawmakers had pushed to keep the program alive. Senator Eric Schmitt, a Republican, said "F/A-XX and F-47 production will create more opportunities to attract engineering and technology talent to Missouri."

Practical Takeaway: There is recent labor history to watch. The workers who assemble Boeing's fighter jets went on a 101-day strike last year, returning to work without winning any concessions from the company, according to Reuters.

Market Reaction and What Comes Next

Investors rewarded the winner and punished the loser: Boeing shares rose 2.25% in extended trading on Tuesday, while Northrop Grumman fell 3.5%, according to Reuters.

One near-term risk remains: Northrop Grumman can protest the decision. The company said it offered a "highly survivable, digitally advanced" fighter and looks forward to receiving more information about the selection.

The Navy has not announced an official designation for the aircraft. First production jets are expected in the 2030s, while the Super Hornet fleet, in service since the 1990s, is expected to keep flying into the 2040s.

Practical Takeaway: With China rapidly fielding advanced combat aircraft, the Navy faces pressure to move quickly or risk operating without a modern carrier-based fighter in the 2030s, Reuters reported.

Bottom Line

Boeing's $20 billion F/A-XX win is more than a single contract: it gives one company control of both U.S. crewed sixth-generation fighter programs, reshaping the defense industrial landscape for a generation.

What to watch next: whether Northrop Grumman files a protest, how Boeing handles the engineering load of two next-generation jets at once, and how Congress funds the program.

FAQ

What is the F/A-XX?

The U.S. Navy's planned sixth-generation carrier-based stealth fighter, intended to replace the F/A-18E/F Super Hornet and EA-18G Growler starting in the 2030s, while flying alongside the F-35C and uncrewed drone wingmen.

How much is Boeing's contract worth?

More than $20 billion for full-scale development plus several test aircraft. With future production, lifetime value could reach hundreds of billions of dollars, according to Reuters.

Who lost the competition?

Northrop Grumman was the only other finalist. Lockheed Martin had been eliminated earlier, in March 2025, after Navy officials determined its design did not meet the required criteria.

Why does Boeing winning matter so much?

Boeing also won the Air Force's F-47 contract in March 2025. The two wins make it the sole U.S. builder of crewed sixth-generation fighters, locking its rivals out of that market for years.

When will the F/A-XX enter service?

First production aircraft are expected in the 2030s. The Navy has not announced an official designation, and many technical details remain classified.
