After blowing past a self-imposed August deadline, the U.S. Navy has finally announced Boeing as the winner of its F/A-XX next-generation carrier-based fighter competition. F/A-XX has become one of the most hotly anticipated U.S. defense procurement decisions in recent memory after the Pentagon tried to shelve the program indefinitely last year.

Boeing had been competing against Northrop Grumman for the F/A-XX contract. An earlier down-select reportedly eliminated Lockheed Martin back in March 2025.

TWZ has now published an initial analysis of Boeing’s winning F/A-XX design based on what can be seen in the new rendering, which you can find here.

As mentioned, the Pentagon had moved to freeze the F/A-XX program in June 2025. Three months earlier, Boeing had won a separate U.S. Air Force competition to produce what is now called the F-47. U.S. military officials had argued that the U.S. industrial base lacked the capacity to support work on two next-generation fighters simultaneously.

Congress subsequently intervened to keep the F/A-XX program running, but its future had remained very murky until earlier this year. In April, Chief of Naval Operations (CNO) Adm. Daryl Caudle said that a winner of the competition would finally be announced in August. Secretary Pete Hegseth and Acting Secretary of the Navy Hung Cao both publicly committed to that same timeline later that month. There had been concerns that the program might have slipped back into limbo after that deadline came and went. Adm. Caudle told Aviation Week‘s Brian Everstine that he himself was no longer aware of when this decision might come on the sidelines of the Tailhook Association’s annual convention last month.

Just two weeks ago, Air Force Gen. Dale White, the service’s Direct Reporting Portfolio Manager for Critical Major Weapon Systems, reiterated concerns about industrial capacity in response to a question about potential challenges in building F/A-XXs at the same time as F-47s. White also acknowledged that these concerns were “not unique” to F/A-XX and F-47.

In this context, Boeing’s win today is perhaps unsurprising. The company will be able to leverage design work it has already been doing in relation to the F-47 program, as well as relevant production experience and supply chains. TWZ had previously highlighted similarities between what was seen in a rendering the company released of its F/A-XX proposal and official renders of what it is building for the Air Force. We still have yet to learn just how closely related the two designs are.

It is also worth noting here that Boeing previously pushed back publicly on the assertion that it was not ready to meet Air Force and Navy needs at the same time.

Regardless of any industrial base considerations, top Navy officials have been consistently vocal about the need for F/A-XX, even after the Pentagon’s move to put the program on ice last year. The service has presented the next-generation fighters as essential for staying ahead of top global competitors like China and Russia, as well as smaller adversaries, such as Iran.

“I know these things are expensive, and I know the defense industrial base is compressed, but we have got to figure out how to walk and chew gum here with aircraft,” CNO Caudle said in January, just weeks before the start of major combat operations against Iran. “The folks that used to be not in [the] headspace that I needed a stealth aircraft of this level to fly a mission into their country, will gain capability that the F-18 [F/A-18E/F Super Hornet] will not match against.”

“This is an ever-evolving theme, and when you’ve got partnerships … well coupled with each other across China and Russia and Iran and North Korea, and terrorist groups that are getting that kit from all of those through back-channel ways, our ability to fly with impunity with our existing airframes is fleeting,” he added at that time. “So, if I don’t start building that [F/A-XX] immediately, you’re not going to get it for some time.”

The conflict with Iran, where U.S. crewed and uncrewed aircraft have now been lost to that country’s air defenses, adds a certain weight to Caudle’s comments here.

The selection of Boeing for F/A-XX also comes now as the Navy is making new moves regarding other aspects of its future carrier air wing plans. In particular, the service is increasingly solidifying its vision for new carrier-based Collaborative Combat Aircraft (CCA) drones. Acting as airborne controllers for advanced drones has long been understood to be a key mission for the Navy’s forthcoming sixth-generation crewed fighters.

Update: 5:52 PM ET –

The Pentagon has now issued a full press release for the F/A-XX contract award to Boeing, which is valued at approximately $20 billion. The deal covers the “full-scale development phase” and includes the procurement of “multiple test aircraft for ground, airworthiness, systems, and weapons integration testing.”

“The F/A-XX is a critical pillar in our commitment to maintaining peace through strength. F/A-XX will dominate contested airspace, extend operational reach, and deliver a decisive combat advantage for the warfighter,” Michael P. Duffey, Under Secretary of War for Acquisition and Sustainment, has said in a statement. “The F/A-XX platform represents a crucial, non-negotiable investment in America’s national security and long-term air combat capabilities. We are joining forces with Boeing to field these capabilities rapidly, ensuring our warfighters possess the lethal and highly networked systems required to deter aggression, project undisputed power, and secure absolute air superiority.”

“This achievement marks a new era for the U.S. Navy,” Acting Secretary of the Navy Hung Cao also said in a statement. “The Sixth-Generation fighter is a generational leap in air superiority and will provide the world’s best aviators with unparalleled capabilities to fight, win, and come home safe. We are excited to partner with Boeing, and for our warfighters to continue to dominate the skies and defeat our nation’s enemies.”

“The F/A-XX will provide advanced carrier-based power projection that extends the range of the most agile and survivable airfields: U.S. Navy carriers. In addition, F/A-XX will be interoperable with manned and unmanned platforms such as Collaborative Combat Aircraft (CCA) and increase the capability of every CCA it teams with,” the press release adds. “Following this contact award announcement, Boeing will deliver the platform to augment and eventually replace legacy F/A-18E/F Super Hornets and EA-18G Growlers beginning in the 2030s, and operate alongside the F-35C.”

The Navy has not yet announced a formal designation for the F/A-XX aircraft. If Boeing’s base design does share significant DNA with the F-47, it is possible that the designation for the new sixth-generation carrier-based fighter could reflect that.

It is also worth noting how muted the F/A-XX announcement has been across the board given how hotly anticipated it was. The contrast with the F-47 contract announcement, which was a live-broadcast event headed up by President Donald Trump from White House, is particularly striking.

Update: 6:14 PM ET –

Boeing has now put out its own press release regarding the F/A-XX contract award, which notes that “technical and programmatic details” about the aircraft “remain classified under U.S. national security and export laws.”

“It’s an honor to be selected to produce the Navy’s first sixth^–generation platform,” Steve Parker, President and CEO of Boeing Defense, Space & Security, said in a statement. “Backed by decades of work, bolstered by game-changing innovations and solidified by the investments we’ve made in new facilities uniquely suited to build multiple products with next generation capabilities, our dedicated and talented team is ready to execute this critical program.”

“Delivering two advanced fighters in parallel was always our plan, and we invested accordingly,” Parker added. “We are ready and able to build multiple concurrent future combat aircraft franchise programs.”

Boeing’s release explicitly highlights a major ongoing expansion of its production and other facilities in St. Louis, Missouri. That work is also widely understood to be supporting the F-47 program, as TWZ reported separately just earlier today.

“Investment in facilities is just one part of the story,” Boeing’s Parker also said. “We’re also investing in technology and people so that we can deliver for our customers.”

As an aside, Boeing also received a separate contract today from the Navy, valued at $16,667,607, to support the final shutdown of the production line for the F/A-18E/F Super Hornet fighter and EA-18G Growler electronic warfare jet.

China’s Chengdu Aircraft Corporation continues to press ahead with the development of its ‘J-36’ next-generation tailless heavy tactical jet. Recent flight testing has offered interesting new views of the still-evolving stealthy design from the top and behind, prompting discussion about the aircraft’s features. There has also been talk recently about whether the jet might receive a laser directed-energy weapon at some point in the future.

The J-36 first broke cover, along with another next-generation tailless tactical jet design generally referred to as the J-XDS, back in December of 2024. There are understood to be at least four, and possibly five, J-36 prototypes flying now. A number of significant changes between prototypes have already been observed over the past two years, as you can read more about here.

The most recent video of a J-36 test flight, seen in the social media post below, began circulating online yesterday. The footage shows the aircraft coming in to land, providing good general views of the uniquely three-engined jet with its two-seat, side-by-side cockpit configuration, especially from the rear aspect. What is seen underscores a previously observed total revision of the exhausts from a trough style to a two-dimensional thrust-vectoring configuration akin to what is found on the U.S. F-22 Raptor. This and other significant changes to the design, including the addition of divertless supersonic intakes (DSIs) all around, not just on top, first emerged last year. The clip also offers a good reminder of just how wide the aircraft is overall.

As this particular J-36 passes by, it can be seen to have a lighter-colored radome, as well as at least one relatively large lighter-colored section on top of the dorsal air intake. A similarly colored radome was first spotted on what is said to be the fourth prototype back in July. This coloring could point to the installation of actual radar in the aircraft’s nose. In TWZ‘s first in-depth analysis of the J-36 back in 2024, we assessed that the jet’s very broad radome area could house an absolutely massive primary array.

The lighter section on top of the fuselage could be an aperture for a conformal antenna tied to a beyond-line-of-sight communications and data-sharing suite. In 2024, we posited that the heavyweight J-36 could serve as an intelligence-gathering and communications relay platform in addition to performing tasks more typically associated with tactical combat jets. Reliable and multi-faceted connectivity would be key for employing the J-36 as an airborne controller for advanced air combat drones, as well.

Another J-36 flight testing video that emerged on Monday, seen below, offers an additional view of the top of the jet, showing multiple lighter-colored sections that would appear to be additional conformal apertures for various antennas. There is a lighter-colored rectangular outline painted around part of the intake on top of the center of the fuselage, as well. The jet’s full paint scheme includes lighter-colored leading and trailing edges, which are critical structures on low-observable (stealthy) designs that often contain additional antenna arrays. Overall, the two-tone coloring is very much in line with what is seen on operational J-20 fighters in Chinese service today. The original J-36 prototype, at least, has notably worn a splinter-type camouflage paint scheme.

Whether or not the two recent video clips show the same J-36 prototype is unclear. The possibility has now been raised that Chengdu may be using a single serial number (36011) on at least some of the J-36 prototypes, a decision that could have been made for counter-intelligence and/or deliberate misinformation/disinformation purposes.

Much still remains unknown about the current or expected future capabilities of the J-36. Aviation Industry Corporation of China (AVIC) did have a placard at its booth at the 14th China International Defence Electronics Exhibition earlier this month that has prompted questions about whether the jet could be equipped with a laser directed-energy weapon. Chengdu falls under the umbrella of AVIC, which is a state-run enterprise. The Chinese-language placard in question describes a “laser weapon tracking system” with a power rating of “*00” kilowatts and a weight of “less than” 837.7 pounds (380 kilograms), per a machine translation. The way the power rating is written appears to mean that it is in the hundreds of kilowatts, which would put it firmly in a class capable of doing physical damage to objects, such as incoming missiles and drones.

Furthermore, an associated graphic shows a turreted system and a computer-generated rendering of a J-36 projecting a beam. The render appears to be from a video that depicts a J-36 using a laser to destroy other aircraft. Another computer-generated video that shows a J-36 using retractable lasers to shoot down incoming missiles has been circulating online since at least last year.

It is not immediately clear how official either of the clips depicting laser-armed J-36s might be, or whether they at all reflect real planned capabilities. The full placard presented at the China International Defence Electronics Exhibition, as seen in the video below, shows a variety of different laser systems, and not just for aerial applications.

The fielding of operational laser directed-energy weapons capable of inflicting any real physical damage has historically proven to be very challenging, and even more so within the size, power-generation, and cooling constraints presented by modern combat jets. As an example, the U.S. Air Force spent roughly a decade working on a podded laser weapon system that tactical jets could use to swat down incoming missiles under its Self-protect High Energy Laser Demonstrator (SHiELD) program. In 2024, the service confirmed SHiELD had “concluded” without achieving its goal of an actual flight test. That same year, the Air Force cancelled plans to test a laser weapon system on an AC-130 gunship.

Despite important U.S. strides more recently when it comes to fielding ground-based and naval laser weapon systems, “there’s nothing that’s on the shelf right now that we are ready to put onto an airplane,” U.S. Air Force Brig. Gen. Douglas Wickert, the commander of the Air Force Research Laboratory (AFRL), told TWZ and other outlets just last week at a roundtable at the Air & Space Forces Association’s (AFA) 2026 Air, Space & Cyber Conference on Tuesday. “The solid-state lasers and the power density and the different ways that you actually – there’s actually a lot of secret sauce in that. How do you make the beam, and how do you form the beam, and how do you pulse the beam, and all that’s in development.”

‘There’s development of the laser itself, but now the power and thermal management system has progressed so much that we can provide the power needed,” Dr. Michael Gregg, head of AFRL’s Air Warfare Directorate, said at the same roundtable. “We’ve also had new designs and engines that we know have the power … to direct that power in certain areas. So, from a system perspective, it’s much more feasible because everything has matured over the last decade.”

China has certainly made substantial investments of its own in laser and other directed-energy weapon capabilities across domains in recent years, and this is clearly an area of interest for the People’s Liberation Army (PLA), in general. When it comes to the J-36 specifically, TWZ has explicitly highlighted in the past how the three-engine configuration could be particularly useful for producing sufficient power to support a host of advanced and electricity-hungry sensors and other capabilities, including directed energy weapons.

Larger questions remain about the exact set of roles the J-36 is expected to fill, as well. The basic design is certainly optimized for straight-line performance, combat radius, and payload rather than maneuverability and agility. The jet has already caused a significant amount of debate just when it comes to taxonomy, as it does not seem to fit inside traditional definitions of ‘fighters’ and ‘bombers,’ something we have explored in detail previously.

“According to Yang Wei – chief designer of the J-20 –, the new [J-36] fighter can penetrate heavily defended airspace that the J-20 and comparable F-22s or F-35s must avoid, placing it a generation ahead,” Andreas Rupprecht, an analyst specializing in Chinese military aviation and TWZ contributor, wrote in a post on LinkedIn last week. “With lower RCS [radar cross section], high speed, and the capacity to control more drones, it could act as a node and command center for systems including J-20s and, especially, unmanned aircraft, while attacking high-value targets from stand-off range with long-range weapons.”

“The type could therefore represent a new class of ‘fighter,’” he added. “Online terms include ‘theater-level deep-penetration command combat aircraft’ and ‘high-performance fighter,’ analogous to a cruiser ranking above a destroyer within the Navy. Recent evidence gives this theory new weight and warrants continued monitoring.”

The J-36, as well as the J-XDS, reflect a larger burst of next-generation air combat developments in China in recent years. This includes an array of new crewed and uncrewed aircraft designed for operations from bases on land, as well as from the PLA Navy’s (PLAN) growing fleet of aircraft carriers and big-deck amphibious assault ships. The Chinese aviation industry’s development of a growing array of flying-wing uncrewed aircraft, some of which are very large, has been particularly notable.

In turn, there is something of an emerging gap between these developments and the pace at which the U.S. military is moving along similar lines, at least publicly. Boeing’s sixth-generation F-47 for the U.S. Air Force is not expected to take to the skies for the first time until 2028, though preceding demonstrator designs have been flying for years already. The U.S. Navy still has yet to officially announce a winner of its F/A-XX next-generation carrier-based fighter competition, and the current timeline for that program producing an operational aircraft is unclear.

As an aside, based on what has emerged publicly to date, there are signs that the F-47 may reflect a distinctly different design philosophy that puts greater emphasis on maneuverability compared to the J-36, and even likely the J-XDS. As mentioned, the J-36 certainly seems much more focused on payload, range, and level flight performance. In July, TWZ published a deep dive exploring why the U.S. Air Force would pursue a sixth-generation fighter with rear-swept wings, canards, and other features despite steady trends in the opposite direction visible in Chinese designs and ones elsewhere globally.

Regardless, U.S. officials have downplayed questions about China’s gaining ground in the air combat arena, or even surging into the lead in certain areas, in the past. “Chinese sixth-generation aircraft are in the nascent stages of development and expected to be operational by 2035,” the Pentagon wrote in its most recent annual report on military and security developments in China, which was published in December 2025.

In the meantime, the J-36’s design is already steadily being refined, and the total fleet of prototypes has been growing, offering new insights into the aircraft’s expected capabilities and roles.
