Boeing has won the US Navy’s contract to develop its sixth-generation fighter, beating Northrop Grumman to build the aircraft that will eventually replace the service’s ageing F/A-18 Super Hornet and EA-18G Growler fleets.
The more than US$20 billion award gives Boeing a major role in the future of America’s sixth-generation fighter fleet, but analysts said the next challenge will be ensuring the company can deliver the programme successfully.
Major turnaround for Boeing’s defence business
The contract marks a significant turnaround for Boeing’s defence division following years of difficulties with major aviation programmes, including the KC-46 tanker and T-7 trainer.
Boeing’s selection in March 2025 to build the Air Force’s F-47 fighter marked a turning point for the company.
Richard Aboulafia, managing director of AeroDynamic Advisory, said Boeing’s control over the future of US manned fighter aviation represented an impressive reversal.
He said the award would mark an important step in an extraordinary turnaround, taking Boeing from a legacy fighter manufacturer facing the decline of its programmes to a company with a major position in the future of US fighter aircraft.
Stacie Pettyjohn, senior fellow and director of the defence programme at the Center for a New American Security, said winning the F/A-XX contract represented a complete shift for Boeing.
The company had gone from facing the prospect of closing its fighter production lines to securing both major sixth-generation fighter contracts.
However, analysts warned that Boeing now faces significant challenges as it attempts to manage several major production efforts simultaneously.
Jeremiah Gertler, senior adviser at AeroDynamic Advisory and a former military aviation analyst for the Congressional Research Service, said the first question was how quickly Boeing could produce a functional F/A-XX.
He said the answer would partly depend on how closely the aircraft was based on the F-47 already under development.
If the two designs had substantial similarities or had been co-developed, the F/A-XX could potentially fly much earlier than expected, Gertler said.
Boeing faces production and workforce demands
Gertler also pointed to potential staffing challenges at Boeing’s production site in St Louis.
The company is already contracted to build the Air Force’s F-47 and T-7A Red Hawk, while also preparing for a significant increase in F-15EX production.
He questioned whether Boeing had, or could recruit, enough workers to keep all four production lines operating simultaneously at a high rate.
Doug Birkey, executive director of the Mitchell Institute for Aerospace Studies, also highlighted the workforce challenge.
He said Boeing would need to proactively manage the demand for labour between the F-47 and F/A-XX programmes, while noting that the challenge could be managed.
In a note to investors after the contract award, Roman Schweizer of TD Cowen said investors would closely examine how Boeing had priced its bid and the structure of the contract, two areas that had affected previous Boeing programmes.
Schweizer said the price suggested the Navy had placed significant importance on Boeing’s manufacturing capacity and ability to deliver at scale.
Navy leaders had previously indicated that industrial capacity and schedule risk were important factors in the decision, while Boeing had spent several years investing in facilities and digital engineering capabilities in St Louis, he said.
Concerns over Boeing’s ability to produce fighter aircraft for both the Navy and Air Force emerged in 2025 after a White House statement opposed funding for the F/A-XX in order to keep the F-47 programme on track.
Boeing defence chief Steve Parker appeared to address those concerns following the latest award, saying that delivering two advanced fighters in parallel had always been the company’s plan and that it had invested accordingly.
Boeing has produced fighter aircraft for the Navy for decades, including the F/A-18 Super Hornet and EA-18G Growler.
Those programmes are now approaching their end, and the Navy also awarded Boeing a contract on Tuesday to support the closure of the F/A-18 E/F Super Hornet and EA-18G Growler production lines.
Northrop Grumman loses F/A-XX competition
For Northrop Grumman, the loss marks a setback in its effort to lead a fighter aircraft programme for the first time since the F-14 Tomcat.
Northrop had previously chosen not to pursue what became the F-47, and losing the F/A-XX contract adds another setback to its fighter ambitions.
However, analysts remained broadly positive about the company, which has a portfolio of major programmes including the B-21 bomber and Sentinel intercontinental ballistic missile, as well as part of F-35 production.
Gertler said the F/A-XX would be a major benefit to whichever company won the contract, but neither company needed the aircraft to sustain its business or defence and aerospace division.
Aboulafia similarly said he did not expect the loss to have a major impact on Northrop.
The latest decision may not be the final word, as Northrop is almost certain to examine options for protesting the award.
However, Schweizer warned that protests against major classified aircraft competitions have historically had a low success rate.
What the contract means for the Navy
The Pentagon said the contract covers the full-scale development phase and the acquisition of multiple test aircraft for ground, airworthiness, systems and weapons integration testing.
The Navy has so far released few details about the aircraft, although officials have acknowledged that it will offer greater range than current aircraft.
At the same time, the Navy is developing its future Collaborative Combat Aircraft, an unmanned combat aircraft designed to conduct missions alongside manned aircraft.
Navy Chief of Naval Operations Admiral Daryl Caudle confirmed in April that the CCA concept and F/A-XX fighter are both linked to the broader concept of the Navy’s carrier air wing, according to USNI News.
Pettyjohn said the composition of the carrier air wing, including the balance between manned and unmanned aircraft, would be critical to the Navy’s ability to project power.
She said having a manned fighter at the centre of that force remained important.
The number of F/A-XX aircraft the Navy plans to buy, how they will be combined with unmanned systems and what weapons will be carried by the fighter will offer clues about the missions the Navy prioritises.
Pettyjohn said those decisions would also indicate how the Navy intends to project offensive power, particularly in the Pacific, where vast distances and China’s long-range weapons are increasingly important factors for US naval operations.
