The Air Force is requesting nearly $3.5 billion in FY’26 to continue work on the F-47, a sixth-generation fighter under development by prime contractor Boeing. According to budget documents released Thursday, the allocation includes $2.6 billion in discretionary funds and $900 million from the GOP-led reconciliation bill currently under debate in Congress.

In contrast, the Navy’s sixth-gen fighter program known as the F/A-XX, would receive just $74 million in R&D funds — 84 percent less than the $454 million the service received in fiscal 2025. The decision comes after the Navy already delayed around $1 billion for F/A-XX in FY’25 due to spending caps imposed by the 2023 Fiscal Responsibility Act.

“We did make a strategic decision to go all-in on F-47,” a senior defense official told reporters during a Pentagon briefing Thursday. The move was prompted “due to our belief that the industrial base can only handle going fast on one program at this time, and the presidential priority to go all-in on F-47 and get that program right, while maintaining the option for F/A-XX in the future,” they added.

President Donald Trump announced that Boeing had beat out Lockheed Martin for the F-47 contract in March, ending a months-long pause to the program’s selection process caused by budgetary and design concerns. The aircraft is envisioned as a long-range crewed fighter jet that will replace the Air Force’s fleet of F-22 Raptors and is expected to field sometime in the 2030s.

The F-47 platform is the centerpiece of the Air Force’s future Next Generation Air Dominance (NGAD) family of systems, which also includes robotic wingman drones called Collaborative Combat Aircraft (CCA). Budget documents indicate that the CCA program would receive a total of $807 million in FY’26, with a majority of those funds coming from $678 million added in the reconciliation bill.

Similarly, the carrier-based F/A-XX is expected to feature longer ranges, enhanced stealth capabilities and be more survivable than the F/A-18E/F Super Hornet it will eventually replace. After Lockheed Martin dropped out of the competition earlier this year, Boeing and Northrop Grumman are both vying to lead the program.

While budget documents at press time did not disclose the specific work planned for the F/A-XX in the next fiscal year, the funding would allow the Navy to “preserve the ability to leverage F-47 work” and prevent “over-subscription of qualified defense industrial base engineers,” the senior defense official said.

The details provided by budget documents end months of ambiguity over the sea service’s plans for the F/A-XX. After Trump’s dramatic rollout of the Air Force F-47 contract award in March, reports surfaced that the Navy would follow suit and name the prime contractor for its sixth-gen fighter the same month.

But that announcement never came, and subsequent reports from Reuters and Bloomberg indicated that funding disputes and industrial base concerns had delayed the program — potentially by three years.

The Navy’s decision to once again scale back funds to F/A-XX is likely to spark ire among lawmakers, many of whom have recently pressed service leadership to move the program forward.

“I’m concerned that any hesitancy on our part to proceed with the planned procurement of the sixth-gen fighters for the Navy will leave us dangerously outmatched in a China fight. We cannot wait,” Rep. Ken Calvert, R-Calif., said in May during a House Appropriations Subcommittee on Defense hearing with Navy leadership. “Further, we cannot expect to grow the industrial base by undermining aviation programs that rely on highly specialized supply chains and skilled labor that cannot be turned on and off like a switch.”

Ultimately, the final decision on the F/A-XX program’s fate is under discussion by Secretary of the Navy John Phelan, Secretary of Defense Pete Hegseth and Trump, a senior defense official told reporters Thursday. When asked whether the Pentagon was considering to create a joint Air Force-Navy program — repeating the F-35 Lightning II acquisition model — the official said “pretty much everything is under consideration to get the tactical air capability that our warfighters need as quickly as possible.”

The tests represent a critical milestone for the CCA program, which is part of the Air Force’s Next Generation Air Dominance (NGAD) family of systems. The drones are expected to fly alongside the service’s manned platforms — including the sixth-gen F-47 fighter jet — to conduct a range of missions and augment the organization’s aircraft fleet. The ground tests bring the two vendors one step closer to conducting first flights of their drones, scheduled for sometime this summer.

“This phase bridges the gap between design and flight, reducing integration risks, boosting confidence, and laying the groundwork for a successful first flight and eventual fielding to the warfighter,” Air Force Chief of Staff Gen. David Allvin said in a statement.

The upcoming ground test phase will include “rigorous evaluations” of both vendors’ prototypes, according to an Air Force statement. The tests will focus on the platforms’ propulsion, avionics, autonomy integration and ground control segments to “validate performance, inform future design decisions, and prepare the systems for flight testing later this year.”

After receiving contracts in 2024 for Increment 1 of the CCA program, General Atomics and Anduril completed critical design reviews of their prototypes last fall. The Air Force in March designated the platforms as the first-ever unmanned fighter aircraft, with General Atomics’ prototype dubbed the YFQ-42A and Anduril’s Fury platform now referred to as the YFQ-44A.

“The CCA program represents a groundbreaking new era in combat aviation, and we remain on schedule to test and fly YFQ-42 in the coming months,” General Atomics President David Alexander said in a statement. “Our work on YFQ-42 will further expand the field of unmanned aviation, and we remain excited for the future.”

Air Force leadership have touted the service’s rapid and flexible approach taken with the CCA program, as it plans to field systems in increments. A competitive production decision for Increment 1 is expected in fiscal 2026, with the first batch of drones planned for fielding sometime before 2030.

“Together, Anduril and the United States Air Force are pioneering a new generation of semi-autonomous fighter aircraft that will fundamentally transform air combat,” Jason Levin, Anduril’s senior vice president of air dominance and strike, said in a statement. “By delivering YFQ-44A at unprecedented speed, we are ensuring that warfighters have ample opportunity to experiment and build the trust required to support operational fielding of CCAs before the end of the decade.”

While General Atomics and Anduril are developing Increment 1 CCA platforms, the Air Force is separately working with five unnamed vendors that are developing the autonomy software for the first batch of drones.

Meanwhile, the service intends to begin development of the next batch of CCA drones, known as Increment 2, during fiscal 2026 to expand mission applications and integrate emerging technologies.

In recent months, Joseph Kunkel, director of force design, integration and wargaming at the Air Force Futures organization, has suggested that future CCA increments could feature a range of options in terms of cost and capabilities — including some attributes that aren’t considered “exquisite” in order to keep price tags low.

Along with initiating ground tests, the Air Force announced Thursday that the CCA drones will be based at California’s Beale Air Force Base, which has been designated as the CCA Aircraft Readiness Unit (ARU).

“The mission of the ARU is to provide combat aircraft ready to deploy worldwide at a moment’s notice. CCA are semi-autonomous in nature so the ARU will not have to fly a significant number of daily sorties to maintain readiness,” the service said in a statement. “The aircraft will be maintained in a fly-ready status and flown minimally so the number of airmen required to support the fleet will be substantially lower than other weapons systems.”

Boeing beat out Lockheed Martin for the contract of the platform — which will be designated as the F-47, President Donald Trump announced during a press conference held in the Oval Office. Northrop Grumman was also in the running to develop the NGAD platform until 2023, when the company publicly announced it was exiting the competition.

The Air Force did not share how much Boeing received for the award due to classification of the program. The service is now on a path to field the NGAD platform sometime in the 2030s.

“The F-47 will be the most advanced, most capable, most lethal aircraft ever built,” Trump said. “An experimental version of the plane has secretly been flying for almost five years, and we’re confident that it massively overpowers the capabilities of any other nation.”

The NGAD contract is a critical win for Boeing and revitalizes its stealth aircraft business. The company has bet billions of dollars in standing up advanced manufacturing facilities at its fighter production hub in St. Louis, Missouri, where the legacy F/A-18 Super Hornet line is expected to end in 2027.

The award also gives Boeing a much-needed boost after its other defense programs — such as the KC-46 Pegasus aerial refueler and new Air Force One jets — have racked up billions in financial losses.

“We recognize the importance of designing, building and delivering a 6th-generation fighter capability for the United States Air Force. In preparation for this mission, we made the most significant investment in the history of our defense business, and we are ready to provide the most advanced and innovative NGAD aircraft needed to support the mission,” Steve Parker, interim president and CEO at Boeing Defense, Space and Security, said in a statement.

The sixth-generation fighter jet is intended to replace the F-22 Raptor and is envisioned as a long-range crewed aircraft equipped with advanced sensors and weapons payloads designed to operate in highly contested environments in the Indo-Pacific.

Lockheed Martin’s loss marks an end to the defense giant’s relative monopoly in the stealth fighter manufacturing business. According to a report from Breaking Defense, the company is no longer vying for the Navy’s sixth-generation fighter jet program known as the F/A-XX because its proposal did not meet the service’s criteria.

The F-47 platform is the centerpiece to the Air Force’s NGAD family of systems concept, which also includes the service’s future loyal wingman drones known as Collaborative Combat Aircraft (CCA) and other advanced command-and-control technologies. The aircraft will be powered by an engine being developed under the Next Generation Adaptive Propulsion (NGAP) program — another ongoing competition between GE Aerospace and RTX subsidiary Pratt and Whitney. 

Chief of Staff of the Air Force Gen. David Allvin said Friday in a statement that over the last five years, the service has been flying X-planes for the F-47 aircraft to test future concepts and proving out its technology. He noted that the experimental work will allow the NGAD aircraft to fly sometime during Trump’s administration.

“With the F-47, we are not just building another fighter — we are shaping the future of warfare and putting our enemies on notice,” Allvin said. “This platform will be the most advanced, lethal, and adaptable fighter ever developed — designed to outpace, outmaneuver, and outmatch any adversary that dares to challenge our brave Airmen.”

The announcement comes after the Air Force decided to pause the selection process for the NGAD platform last summer to reevaluate the service’s design concept against predicted threat environments, as well as attempt to lower the platform’s cost. The service initially planned to award the NGAD contract before the end of last year, but ultimately decided in December to push the decision to the Trump administration.

During the pause, former Secretary of the Air Force Frank Kendall said the service was “taking a hard look” at the platform’s design to ensure the stealth fighter jet would be able to address new and emerging threats. China’s arsenal of advanced weapons and NGAD’s survivability on large airfields were some of the elements considered during the evaluation, he said.

In a statement, Allvin said “the F-47 has unprecedented maturity. While the F-22 is currently the finest air superiority fighter in the world, and its modernization will make it even better, the F-47 is a generational leap forward. The maturity of the aircraft at this phase in the program confirms its readiness to dominate the future fight.”

Budget constraints also influenced the service’s decision to pause NGAD’s selection process. Original estimates for the sixth-gen aircraft were predicted to be around $300 million per unit, but Kendall said last year his ideal price point would be similar to the F-35 Lightning II — about $100 million, depending on the variant.

Allvin said in a statement that the F-47 will have a lower price tag than an F-22 — which has a unit cost of around $143 million. The Air Force requested $2.7 billion for the platform in its budget request for fiscal 2025, indicating that it planned to spend $19.6 billion on the aircraft over the next five years. 

“Compared to the F-22, the F-47 will cost less and be more adaptable to future threats — and we will have more of the F-47s in our inventory,” Allvin said. “The F-47 will have significantly longer range, more advanced stealth, be more sustainable, supportable, and have higher availability than our 5th generation fighters.”
