Yesterday, TWZ published an analysis of a thermal image purportedly showing a previously unseen advanced aircraft design, which appears to be a precursor to the U.S. Air Force’s forthcoming F-47 fighter from Boeing. The image, which went viral online and is from a video that has now been released, is said to have been captured near the U.S. military’s secretive Groom Lake test base, better known as Area 51. It turns out, as a number of our readers have pointed out, there may be some interesting similarities between this secret aircraft and a “Christmas tree” fighter design concept crafted decades ago by Darold Cummings, one of the top minds behind Northrop’s YF-23 Black Widow.

You can find our full initial assessment of what we may be seeing in the viral image, first posted online by the Project Fear YouTube channel earlier this week, here. What we saw initially, as shown below, appeared to feature what could be described as a “double arrowhead” profile to its forward fuselage. This is a very distinct design cue, but it could also be a result of the low quality of the image and the artifacts that come with consumer-grade thermal imagers, which was what the aircraft was recorded with.

Project Fear has now released the full video it says it captured near Area 51, seen below, and it underscores the aforementioned points about image quality. So, it is possible the aircraft has a more traditional low-observable ‘shovel nose,’ instead. Nonetheless, the Christmas tree fighter is an interesting trip down lesser-known fighter development memory lane that is worth examining, in particular what such a unique nose configuration would provide an advanced fighter aircraft.

The full clip of the mysterious aircraft passing by starts at around 49:34 in the runtime of the video below if it does not automatically start playing at that point.

In a post on LinkedIn around the end of last year, Darold Cummings shared an intriguing blueprint of a relevant-looking advanced fighter concept, along with additional details about the design and its genesis. Cummings is currently the founder and president of ForzAero, but has an extensive resume in the aviation industry dating back decades. As noted, he was a key figure at Northrop in the development of the YF-23, which ultimately lost out to what became Lockheed’s F-22 Raptor. He also led the team at Boeing that developed the X-40A Space Maneuver Vehicle, which was used as a testbed in support of work on what evolved into the X-37B reusable spaceplane. He was Chief Engineer/Chief Designer of Rockwell’s Ranger 2000 Jet Trainer, as well.

“I was hired by Bob Sandusky in 1982 to be the Chief Configurator for the Northrop ATF [Advanced Tactical Fighter] program (YF-23). In early 1983 Bob said that Northrop had tried to develop a ‘4-spike’ (like the B-2) fighter, but it couldn’t be done, since a flying wing fighter was not possible,” Cummings wrote in his post on LinkedIn. “I told him I could design one, and he said to give it a try. The only way to accomplish this was with a series of highly swept (55 degree) surfaces over the entire length of the aircraft. The result was the DP-21, created in June of 1983.”

“4-spike” here essentially refers to the total number of radar cross-section hot-spots and where they are located, each pointing in a different direction in azimuth. The fewer ‘spikes’ a low-observable (stealthy) aircraft has, the easier it is to manage its radar signature, and to make it harder to detect and lock onto, but it’s also where those spikes are located that matter.

A four-spike design like the B-2 critically has nothing from the head-on aspect, as well as from the rear, which helps immensely with survivability. These are the most critical signature areas, especially the front as the aircraft is heading into hostile territory. Also, because these are located along the path of flight, these spikes can stay consistent on a threat radar as the aircraft moves directly toward or away from the sensor, and are not fleeting in nature like those from the side. So a four spike aircraft would be very attractive for a tactical fighter meant to persist in contested territory.

“I never considered this to be a serious contender for the ATF program, as the aircraft was unstable beyond 10 degrees angle of attack!” he also noted.

“Back in 1983, the ‘Christmas Tree’ DP-21 would have been difficult to fly. However, with modern flight control systems, this design could be controlled, even at high angle of attack,” Cummings told TWZ directly today after we reached out for more information. “Low observability is always better served with long edges on the design, so the small arrow-shaped foreplane is not ideal, but it still has low RCS characteristics, just not the optimum.”

“Wing shaping is always a trade-off for maximizing LO. Most of the trades have to do with the leading edge contour, which is a large contributor to signature,” he continued. “The canard has to be designed to be ‘ported’ during penetration, as this minimizes the signature. On the YF-23, the V-Tail was ‘ported’ in penetration for the same reason. This is certainly possible with modern flight control systems.”

“Ported” in this instance refers to keeping the control surface locked in the same geometric plane as the wing while cruising.

We also asked Cummings directly whether it was possible his DP-21 concept had an influence on what is seen in the viral thermal image, assuming it is authentic. And we asked for his take on what impacts Boeing’s experimental X-36 and Bird of Prey designs may have had on the F-47, as well.

“My DP-21 aircraft image has been available publicly for quite some time, so it is possible it had some influence, but that is only speculation on my part,” he told us. “I believe the X-36 and Bird of Prey have both influenced the F-47 design. I have always been impressed by the X-36, as it seemed to be ahead of its time.”

“The Groom Lake images are truly intriguing,” he also noted. “It is a viable concept.”

“I think the main thing to remember is that NO ONE thought a 4-spike design (like the B-2) was possible, and my DP-21 was an example of how it was possible,” he added. “A 4-spike design for the F-47 would truly be impressive!”

As TWZ already wrote yesterday, based on what is visible in the image:

“The image shows an exotic design by any interpretation. The aft-set lambda-type wings appear to have a camber and wingtip droop, as on the Boeing Bird of Prey demonstrator. There are very large canard foreplanes — a feature that appears prominently on F-47 renderings and which we have written in detail about in the past. The broad nose, too, is something that has been included in depictions of the F-47, although we have really no idea to what degree these are based in reality. It’s worth noting that in this new thermal image, it has a distinctive double-arrowhead shape, tapering in again in front of the canards. Even the canards themselves may have more than one plane, with the outer tips being drooped, matching similar architecture as the wing. The fuselage then tapers down in the center before the wing roots begin.”

“The aircraft is very likely to be tailless, a feature common to most sixth-generation concepts seen so far. However, since it’s seen from below, we cannot be sure about this aspect of its configuration.”

“As for the powerplant, it is most likely a twin-engine design, like the F-47, a theory reinforced by the sawtooth-type trailing edge. There is no obvious suggestion of any exhaust plumes, which seems odd, but that could be the result of the sensor being used in combination with the aircraft’s power setting at the time of recording, as well as general thermal signature reduction capabilities that are part of the design.”

“Soon after Boeing won the contract for the F-47, we looked at how it might have been influenced by the Phantom Works X-36, also a tailless-canard design.”

As mentioned earlier, the full video Project Fear released today does raise new questions about the exact profile of the front of the design seen in the footage. The idea of using a shovel nose profile on a stealthy aircraft dates back to Northrop’s Tacit Blue demonstrator, and it was found in its modern form the YF-23. It has since become common to see on low-observable (stealthy) designs, and has been notably present in official renders of the F-47 released to date.

Beyond the nose end, there are still some very broad similarities in the shaping of the wing and main body of the aircraft seen in the footage and Cummings’ DP-21 concept.

To date, there are no indications that an F-47 EMD prototype has flown. Air Force officials have said on multiple occasions now that first flight of the service’s new sixth-generation fighter is expected to come in 2028.

We do know that Boeing and Lockheed built flying demonstrator designs that fed into the Next Generation Air Dominance (NGAD) initiative, under which initial development of what has become the F-47 was carried out. Past reports have raised the possibility that there was a third NGAD demonstrator, which might have been built by Northrop Grumman. That company voluntarily dropped out of the NGAD combat jet competition around 2023, and is said to have been on the verge of being cut at the time.

As we noted yesterday, what is seen in the viral thermal image could be unrelated entirely to the F-47. The Navy has also been pursuing a carrier-based sixth-generation fighter, commonly referred to as F/A-XX, in recent years. There has been at least some crossover between F/A-XX and the Air Force’s NGAD effort. A rendering Boeing has shared of its proposed F/A-XX design looks very much in line with what has been shown of F-47 to date. Northrop Grumman is the other company currently competing to build the Navy’s sixth-generation carrier fighter, and has released its own renderings.

In addition, it should be said that official F-47 and F/A-XX renderings released to date will have been carefully manipulated to maximize security of the programs, both of which remain highly classified, and to provide disinformation to adversaries.

As an aside, Darold Cummings also shared his take on a prospective navalized version of the F-47 in a separate post on LinkedIn last year. At that time he wrote:

“I received a DM asking if I had envisioned a Navy version of my recent F-47 fighter concept,  such as  the F-35A to F-35C approach. I recently completed my F-47 Navy version, which I call the F-47N. However, the approach I took was somewhat different: The F-35C used a larger wing for low speed lift, whereas I used my original F-47 wing planform, and added a canard for more low speed lift and control. The canard design (inspired by the X-36), coupled with the Multi-Axis Thrust Vectoring (inspired by the X-44), provided a very reasonable first cut at a Navy version. In general, a canard layout has been treated as adding more radar signature to a fighter. However, on the YF-23 we found that if the all-moving surface (it was a V-tail on the YF-23) was kept “ported”, in this case aligned with the wing plane during cruise, the impact on LO was not a large impediment to signature reduction. The ability to keep the canard ported is achievable using thrust vectoring for trim in cruise and penetration modes.”

Cummings’ interpretation of the F-47 design at that time notably did not reflect his previous DP-21 concept. The X-44 design he mentioned is also known as the Multi-Axis No-Tail Aircraft (MANTA), and was derived from F-22. At least to our knowledge, the MANTA never came to be. The designation was recycled for an entirely unrelated flying wing-type drone, the existence of which was first reported by TWZ.

It’s also worth noting that the design in the newly emerged thermal video could be tied to one of many other programs, including uncrewed ones. Still, it is very much in line with what we would expect to see from a design related to the F-47 and it seems very likely this is the Boeing NGAD demonstrator, if the video is indeed authentic, which it appears to be.

It would be nice to say that we will have to wait and see whether this aircraft turns out to have a more traditional shovel-shaped nose, or even a mild Christmas tree-like design, but we may never see it again. Hopefully that is not the case, especially after the F-47 goes public, but the final design will have significant differences from its technology demonstrator forebears.

Shield AI revealed a revised planform configuration and new details about its extremely ambitious X-BAT jet-powered autonomous stealth ‘fighter’ drone at April’s Sea-Air-Space 2026 convention, as detailed by TWZ. At the event, I was able to speak at length with Armor Harris, the chief designer of X-BAT, who was keen to discuss the status of the project. You can read TWZ’s original deep dive exclusive interview with Harris that was published when X-BAT first emerged from the shadows last October here.

The tail-sitting X-BAT, designed to take off vertically and land the same way, is planned to start vertical takeoff and landing (VTOL) testing before the end of this year. Harris explained how it is designed to fly combat missions under the control of the company’s Hivemind artificial intelligence “pilot” and how Shield AI has designed-in payload bays that are roughly the same size as those found on the F-35, which will enable it to carry many of the same weapons as the stealthy crewed fighter.

The X-BAT concept is aimed to disrupt not just the budding advanced autonomous drone marketplace, but parts of the fighter market too. So much hangs on the VTOL element that the airframe is designed around, so to say that a lot is riding on those tests is an understatement.

Here is the full interview from the show floor at Sea-Air-Space:

Meet The Man Behind The X-BAT Autonomous VTOL Fighter Drone

Satellite imagery has emerged showing China’s two massive stealthy flying-wing high-altitude, long-endurance (HALE) unmanned aircraft at its secretive test base near Malan. TWZ first identified both of the previously unseen aircraft last year in Planet Labs archived imagery of the airfield, which is known to be on the leading edge of the PLA’s unmanned combat aircraft development efforts. However, this is the first time both have been captured outside their hangars simultaneously, or on the main apron at all. Overall, the image, dated March 26th, 2026, underscores the major uptick of very advanced drone testing activity at the installation.

The flying wing with the longest wingspan (red arrow in the image at the top of the article), which some have dubbed “WZ-X,” and what we refer to as “The Monster of Malan,” is parked on the main apron next to the runway. The very large flying wing has a span of approximately 173 feet — roughly the width of a B-2 Spirit stealth bomber. You can read more about this impressive aircraft in our previous coverage here and here. Other details about its true designation or its manufacturer remain unknown.

The second large flying wing (green arrow) is seen in the image sitting outside a hangar that is part of the sprawling new high-security facility on the opposite side of the complex. It features a ‘cranked kite’ planform with a wingspan of approximately 137 feet, although it would appear to have a significantly higher gross weight and likely lower operating ceiling than its wider stablemate. Based on our previous analysis, this variant is suited for the intelligence, surveillance, and reconnaissance (ISR) role, but could also work as a supersized unmanned combat air vehicle (UCAV) capable of performing very long-range heavy strike missions.

Both of these aircraft appear to have been flying now for a number of months. You can read about this here and here.

There is also what appears to be a stealth fighter-like drone (orange arrow) and a Xi’an Y-20 transport plane on the main apron in the image.

China has shown off a very large number of fighter-drone concepts, very loosely similar to the U.S. Collaborative Combat Aircraft initiative, in recent years. A Chinese military parade in 2025 was really Beijing’s major public thrust into this area of advanced fighter-like drone development. Since then, testing of at least one configuration has been ramped up considerably.

Just reviewing Planet Labs archived images of Malan in recent months shows the aircraft configuration seen above to be very active at the base. This relatively large unmanned ‘fighter’, analogous to a manned light-to-medium weight fighter in size, is a tailless design that features a very similar planform as the J-XDS 6th generation manned fighter. It also appears similar in shape to another CCA-like aircraft that has been photographed flying.

One drone shown off during China’s big military parade looks very similar to it, in particular. But regardless, this general design appears to be a focus of testing at the base.

Other mysterious aircraft have appeared at the installation as well, which is clearly set up specifically to run many programs within its high-security confines at any given time.

Beijing is actively pursuing a range of flying-wing drones of various sizes, including large HALE drones, designed to perform a diverse set of missions, including ISR and strike. For many years, TWZ has assessed that this was an area of the Chinese aviation industry most likely to see an explosion of investment. The WZ-X is still the largest Chinese design in terms of wingspan that we have seen in this category to date. The cranked-kite design is certainly the heaviest.

This new look at China’s two large flying wing combat drones comes as we got our first good look at America’s own RQ-180 HALE stealth drone, which has been flying for some time and is now being used operationally. It also comes as China is rushing ahead on all fronts with its next generation air combat ecosystem, and making impressively quick progress to show for its efforts. Still, a formidable looking aircraft doesn’t mean it can fight as impressively as part of a joint force as it looks, or survive against enemy air defenses. Regardless, China is clearly betting substantially on advanced and large unmanned flying wing designs.

Driven by a race to get ahead of quickly evolving enemy capabilities, the U.S. Navy is now aiming to enter the next step of contracting for its 6th-generation crewed fighter – known as F/A-XX – by August. Despite intervention from Congress, the next-generation carrier-based fighter has remained in limbo since the Pentagon moved to effectively shelve the program last year.

That’s according to Chief of Naval Operations (CNO) Adm. Daryl Caudle, who spoke with reporters Monday at the Sea-Air-Space 2026 exposition near Washington, D.C. In response to a question from TWZ, Caudle acknowledged the uncertainty that has kept F/A-XX in a holding pattern, even as the Air Force’s future fighter, dubbed the F-47, has forged ahead. The current competitors for the F/A-XX are Boeing, which is also the F-47’s prime contractor, and Northrop Grumman.

“One of the challenges we’re seeing is, not only [are] our peer competitors improving their capability for anti-air, either air-to-air or surface-to-air, but the lower cost of entry of very capable weapons is also making more players on the field in which that level of stealth and technology is required,” Caudle, the Navy’s top officer, said. “So this is not about the need for a peer adversary. This is just having an aircraft that can operate with a level of uncertainty and with the acceptable level of risk.”

This is in line with arguments Caudle made in favor of moving ahead of F/A-XX in January, where he cited growing threats posed by smaller nation-state adversaries, including Iran, as well as non-state actors.

Today, Caudle again emphasized that he nevertheless had been “very vocal” on the need for a carrier-based next-generation fighter, and had expressed “many times” to Deputy Secretary of War Steve Feinberg that the service had to secure the aircraft. It’s important, Caudle said, for both the future carrier air wing and collaboration and planning with the MQ-25 Stingray, the Boeing-made carrier refueling drone set to reach initial operational capability later this year.

“It ties to our MQ-25 for stealth refueling. It ties to our reach. It ties to the work we’re doing for making the carrier air wing something that remains very effective into the future based on the range in which you can operate safely,” Caudle said. “So the need’s clearly there.”

MQ-25A Stingray first taxi test

While it was recently reported that the Navy, bolstered by funding from Congress for the new F/A-XX, planned to award a contract for the program by year end, Caudle said August was now the likely timeframe.

As noted, the Pentagon had moved to essentially shelve F/A-XX in its Fiscal Year 2026 budget request, with the Navy only requesting a relatively meager $74 million for the program. U.S. officials said at the time this decision had been driven largely by concerns about the ability of the U.S. industrial base to support work on two sixth-generation fighters, the other being the F-47, simultaneously.

Congress subsequently interceded, appropriating $1.69 billion for F/A-XX through a combination of regular spending bills and the One Big Beautiful Bill Act. From a budgetary perspective, the Navy’s next-generation fighter program remains well behind the F-47, which has already received billions in funding and could be in line to get approximately $5 billion more in Fiscal Year 2027. The Navy only appears to be requesting an additional $140 million for its new carrier-based combat jet in the $1.5 trillion proposed defense budget for the next fiscal cycle.

“We’ve got a lot of airframes out there. We’ve got an F-35 program. We’ve got a F-47 program. You know, we’re still building the [F/A-18 Super Hornet] … there’s a lot of airplanes being built,” Adm. Caudle said today. “The Air Force has got a lot of demand on the system. The Navy’s got a lot of demand … One of the contractors who would make this plane for us is in a place where they really can’t deliver in the timeframe we need it. So there was, you know, a check twice, cut once, kind of mentality here on this decision. And now there, I think we’re all on the same page on the reason why the hard look needed to be done. I’m good with it.”

As noted, Boeing and Northrop Grumman are in competition to produce the F/A-XX, a program that first took shape as a Navy request for information in 2012. An earlier down-select reportedly eliminated Lockheed Martin in March 2025. Last August, Northrop Grumman released a rendering of its concept for the aircraft, showing a streamlined nose and landing gear on the front of a carrier with the tagline, “Project Power Anywhere.” Boeing’s concept, released the same month, drew visual comparisons to its F-47 Next-Generation Air Dominance fighter for the Air Force.

Citing classification, Adm. Caudle said today he couldn’t provide any information on design or payload details that give the Navy confidence in pursuing F/A-XX despite the adversary threats he mentioned. However, he suggested speed was increasingly essential to having a chance at maintaining overmatch.

“We monitor very closely, red-team that very hard, and assess that threat with a predicted trajectory of whether or not the existing designs we’ve seen will still overmatch that,” he said. “So I think we’re okay there, but we do know that our existing airframes could become vulnerable to some of those threats by the time [it’s fielded] … because it takes time to deliver that, that our existing airframes could be vulnerable to some of those threats, and we want to make sure the air wing of the future can still participate.”

Despite Caudle’s comments today, it should be remembered that this is not the first time that major progress on the Navy’s next-gen fighter has supposedly been imminent. Last October, Reuters reported the program had been greenlighted by Secretary of War Pete Hegseth, with a contract expected to follow in short order. 

Aside from funding moves from Congress to ensure the survival of the F/A-XX program, no public steps have been taken to advance the program since.
