China's J-36 Very Heavy Stealth Tactical Jet Photographed Head-On For First Time
New imagery of China's 'J-36' very heavy tactical 6th generation jet has just emerged out of China. The photos shows a long-awaited perspective of the aircraft — taken from the front — that confirms our analysis that the aircraft features a very large and broad bubble canopy to go atop its equally broad nose section. Under that canopy would be two crew sitting side-by-side, similar to the F-111 and Su-34's arrangement, among others. The image also offers a view of the dorsal inlet on the three-engined aircraft, along with its diverterless supersonic inlet (DSI) 'hump,' which appears very large here. Overall, the photos serve as a reminder of just how big this aircraft is. Like many tailless designs, especially stealthy ones, they can look far smaller from the side than from the front, top or bottom. While we have become accustomed to the J-36's modified delta planform, the head-on perspective really underlines the proportions and mass of Chengdu's next-generation tactical jet design. In the imagery, we can also just make out the J-36's lower trapezoidal air inlets, similar to those found on the F-22, as well as one of the jet's unique large aperture electro-optical windows on the side of the nose. That fixture is seen glaring gold in the low-angle light. As is often the case, we must note that the imagery appears authentic, but we cannot be certain of that. Still, it was only a matter of time until we got a head-on angle of the J-36 and this screenshot of a DSLR camera screen (you can see the smart phone's lenses in the reflection) goes along with the progression of 'leaks' out of China we have come accustomed to over many years when it comes to new military aircraft designs. Very interesting but strange frontal view of the CAC J-36, which due to the 'merging' of the top air intake, DSI bump and the wide cockpit makes it look even wider … — @Rupprecht_A (@RupprechtDeino) May 31, 2025 Çin'in Kuyruksuz Savaş Uçağı J-36'nın son test uçuşuna ait görüntüler ortaya çıktı — Times of Defence (@timesofdefencee) May 31, 2025 This new imagery also comes just days after we got the clearest look at Shenyang's smaller, but still heavy-weight 6th generation fighter aircraft, referred to unofficially by a number of designations, including J-XDS and J-50. Not only do we get a more detailed underside view, but we also get a full side-on shot, which shows just how blended the canopy of the aircraft is with its upper fuselage, as well as a better look at the profile of its huge nose. The bottom view gives us a better look at the weapons bay arrangement, as well as its F-22-like nozzle configuration. We can also confirm an EO/IR blister (without its glass) under the nose. The aircraft looks to feature a single pilot/crew. The small side doors where a side weapons bay would likely go remain a bit of a mystery. The aircraft's unique swiveling wingtip control surfaces are also very clear here. Once again, the profile of the nose is striking, and it clearly can accommodate a very large and powerful AESA radar. You can read our very in-depth analysis on these two aircraft, including the knowns and the unknowns surrounding them, which still proves entirely accurate, at this link. Both aircraft were 'unofficially unveiled' via a series of videos and images spilling out of the country of presumably their first test flights back on December 26th, 2024. As we have stated since they first appeared, by summer we will likely have a look at all angles of both aircraft, and in increasing definition, based on how the flow of images of new high-profile military aircraft have historically appeared out of China. So stay tuned for more. Contact the author: Tyler@

New Views Of China's Next Generation Fighters
Flight testing of China's two new next-generation fighter designs is continuing apace and offering new insights into both aircraft. The latest imagery of the larger of the two designs, commonly — but unofficially — called the J-36, offers the clearest look to date at the exhausts for its three engines and a new angle into its possible two-seat cockpit. Additional views of the second type, referred to variously as the J-XDS and J-50, show the interesting bay configuration on the side of the fuselage immediately behind the air intake and highlight other distinctive features like its swiveling wingtip control surfaces. TWZ has previously published a highly detailed analysis of both the J-36 and J-XDS/J-50, which readers can find here. There are no clear indications that the latest pictures and videos of the J-36 and J-XDS/J-50 have been fabricated, but this remains a possibility, albeit a very small one. Versions of some pictures of the aircraft that have been deliberately enhanced using generative artificial intelligence (AI) to try to glean more details are known to be circulating online. Many phone cameras now produce images that are similarly 'smoothed' by default, as well. The newest views of the J-36 in a video and associated still images, seen in the social media posts below, which are said to have been shot in the city of Chengdu. The Chengdu Aircraft Corporation, which has its main plant there, is responsible for the aircraft. Finally got my hands on this video! Crystal-clear footage of Chengdu's 6th-generation fighter jet soaring over Chengdu Airport. Absolutely amazing! #Chengdu6thGenFighter# — GaoFrank (@gaofrank75) April 23, 2025 Wow! I hope this latest image of the J-36 is legit but usually @琴石2022 on Weibo is quite credible! — @Rupprecht_A (@RupprechtDeino) April 23, 2025 As noted, the new rear aspect view of the J-36 gives the clearest look we've seen at the engine exhausts for its trio of engines, which is already a highly unusual feature of the aircraft. As seen below, we can now see 'petals' extending out over the top of the exhaust trenches that sit inward of the aircraft's tailing edge. This only underscores TWZ's previous analysis about the J-36's exhaust configuration and its major similarities in form and function to that found on Northrop's YF-23. The YF-23 also notably featured an exotic intake design with boundary layer pores to help improve airflow, as you can learn more about here. As we have previously written about the J-36's exhaust arrangement in general: 'This is a clear low-observable play both for radar and infrared signature management. Recessing the engine exhaust before the aircraft's upper trailing edge is a classic low-observable design element that Northrop largely pioneered with Tacit Blue, B-2 Spirit, and YF-23. The ejected exhaust is spread out and has the potential to be actively cooled by this upper deck area. Above all else, this provides very limited line-of-sight to the engine exhausts themselves, which helps significantly in minimizing infrared signature, as well as radar cross-section, from most aspects.' The J-36 video also offers a new view into the aircraft's cockpit. Since the aircraft first emerged publicly, there has been speculation that it may have a two-seat cockpit with side-by-side seating. The imagery we have now is still inconclusive on this detail, but the possibility that two distinct heads-up displays may be visible has been raised by Andreas Rupprecht, a longtime Chinese military observer and contributor to this website. No, it clearly looks like two HUDs — @Rupprecht_A (@RupprechtDeino) April 23, 2025 Additional pictures and videos of the J-XDS/J-50 from the Shenyang Aircraft Corporation have also been circulating online in the past week or so. And the same one in cut-out form …(Images via @Captain小潇 on Weibo by OPPOFind 8) — @Rupprecht_A (@RupprechtDeino) April 23, 2025 Original image — John Jones (@nibelogn1996) April 17, 2025 Another set of images showing SAC's J-XDS prototype with its landing gear down and from the side … unfortunately still very small & blurry!(Images via @琴石2022 from Weibo) — @Rupprecht_A (@RupprechtDeino) April 23, 2025 A test flight of Shenyang's sixth-generation aircraft took place today. It is clearly visible that the aircraft's swiveling wingtips are rotating. — 笑脸男人 (@lfx160219) April 23, 2025 As mentioned, most interestingly, a bay of some kind with a pronounced bulge at the front is now plainly visible on at least the right side of the fuselage behind the air intake. It is also positioned right in front of the main landing bay on that side of the aircraft. Whether or not the J-XDS/J-50's bay may be for weapons or intended to serve some other purpose is unknown. Questions have already been raised about whether there is enough internal space in this part of the aircraft to hold a relevant munition. It is worth noting here that China's J-20 stealth fighter has weapons bays in roughly the same location, which also have a novel configuration wherein the missiles inside pop out fully along with their launch rails before firing, as you can read more about here. We also have much clearer views of the J-XDS/J-50's unique swiveling wingtip control surfaces. TWZ has previously assessed that these wingtips most likely help provide additional stability for the tailless aircraft, and has explored the advantages and disadvantages of such a design decision in detail. No idea yet, but also interesting what looks like massive actuators … — @Rupprecht_A (@RupprechtDeino) April 23, 2025 Though any new details about the J-36 and J-XDS/J-50 continue to draw particular attention, they represent just a portion of significant military aviation development efforts known to be ongoing in China, as well as additional work assumed to be going on outside of the public eye. Also today, a satellite image available through Google Earth began circulating online showing a curious object with a stealth fighter-like appearance, including a modified diamond-like delta platform, canards, and twin vertical tails, on the apron in front of the passenger terminal at Jining Qufu Airport in Shandong Province in eastern China. Additional satellite imagery from Planet Labs that TWZ reviews shows that it has been there since at least September 2024. This is all doubly curious given that Jining Qufu Airport, which had been collocated with the People's Liberation Army Air Force's (PLAAF) Jining Air Base, was officially closed in December 2023. What the 'airframe' is unclear, but it seems very likely to be a mock-up of some kind. It shows some rough similarities, but also significant differences to the Baidi Type-B, also known as the 'White Emperor,' an entirely fictional 'space fighter' design that the Aviation Industry Corporation of China (AVIC) displayed at the 2024 Zhuhai airshow. Comparisons have also already been drawn to vaguely J-20-esque 'shapes' that emerged at the remote Lintao Air Base in north-central China in 2022. However, the structure of the wings and the nose of the object at Jining are distinctly different from those previously seen at Lintao, which may also be mock-ups or decoys. A video is also now making the rounds on social media that has prompted questions about whether yet another new Chinese advanced military aircraft has emerged. What can be gleaned from the video is limited given how far away the aircraft is in the footage and its overall quality. Its provenance is also not immediately clear. What can be seen does not immediately appear to directly align with any known Chinese designs. Its overall shape also does not fit with a still-unidentified tailless fighter-like airframe that emerged at Shenyang's main plant in January, which TWZ was first to report on. China is reportedly testing a third platform in northern China, according to the latest visuals that have emerged on social aircraft appears to be different from the two previously known tailless designs currently undergoing is still too early to… — International Defence Analysis (@Defence_IDA) April 23, 2025 Yes and as I noted here I'm confused … it is so much blurry. The best guess would be some sort of UAV/UCAV. We simply need to wait for more. — @Rupprecht_A (@RupprechtDeino) April 23, 2025 At the same time, it would hardly be the first time a new advanced Chinese aircraft design has emerged suddenly. The dramatic appearance of the J-36 and J-XDS/J-50 flying on December 26th last year, despite no imagery having previously emerged of either aircraft, is a prime example. Ongoing testing of the J-36 and J-XDS/J-50 is certainly continuing to reveal new details about those designs. We had previously predicted that reasonably high-resolution images of the two aircraft would emerge by early summer in line with the pattern of past Chinese rolling 'leaks.' If other advanced Chinese military aircraft are now flying or are otherwise progressing into the latter stages of development, additional details may well begin to emerge about them, as well.

Canopy Seen Clearly On China's Next Gen Tailless Stealth Fighter For First Time
China's next-generation tailless heavy fighter from the Shenyang Aircraft Corporation seemed to have taken a months-long hiatus between its first known flight and its second. Since then, it has been seen in the skies at an increasing rate. New images and video coming out of China show the jet – referred to unofficially by a number of designations, including J-XDS and J-50 – on another recent test sortie, with clearer shots of the enigmatic stealth fighter than ever before. This includes what appears to be our first real view of its cockpit canopy. The aircraft's canopy has been of particular interest since the plane first appeared to the public on December 26th, 2024. Up until now, no images have clearly shown it. The plane's broad nose, paired with the ground-based perspective of the photos, and their low quality, previously made only what may have been a part of a canopy visible in imagery. This led to the question of whether the heavy fighter-sized aircraft was crewed at all. J-XX/Shengad may have flown again today — 東風 (@eastwind6699) April 16, 2025 Our very in-depth analysis on this aircraft, and its larger tri-engined Chengdu Aircraft Corporation counterpart, came to the conclusion that the aircraft was almost certainly crewed. With this latest imagery, we can finally put that question to rest conclusively. One image shows a side-on view of the aircraft, providing a new perspective to analyze. Above all else, it depicts a very streamlined bubble canopy that blends closely with the upper fuselage. Canopies and cockpits can be a major hot spot for radar reflections. Minimizing their return is critical to the survivability of a low-observable crewed aircraft. In this case, for the same reasons that the canopy was so hard for us to see until now — it is difficult to view from lower aspects — also helps with keeping it out of line-of-sight of radar systems positioned below it. These can be on the surface or lower-flying aircraft. The service ceiling of the fighter is unknown, but it should be quite high in order to maximize its performance, as well as its sensor and weapons reach. It remains unknown if the jet has one or two crew. The canopy does look quite long, which could possibly accommodate a tandem crew layout. As it seems, we finally have a quite decent side shot of SAC's J-XDS from its flight today and also for the first time a clearer proof it has indeed a canopy. — @Rupprecht_A (@RupprechtDeino) April 16, 2025 This side view also provides a bit better sense of scale and form of the new jet. Its diamond-shaped forward fuselage with a prominent chine line high up near the cockpit is also readily visible. The blister under the nose that could represent a faceted aperture for an electro-optical targeting and/or infrared search and track (IRST) system, similar to what's found on the J-20 and the U.S. F-35 Joint Strike Fighter, is also visible. Another angle from the lower rear gives us a clearer view of the aircraft's exhausts. As expected, they are 2-D and likely thrust vectoring types, very similar to the U.S. F-22 Raptor's arrangement. This configuration would balance low observability, performance, agility, and especially stability, considering just how unstable a tailless tactical jet like this would be. China has been displaying its thrust vectoring engine concepts since at least 2022, with the one subscale model on the show floor at Zhuhai looking very similar to what we see in the latest imagery. We also see the unique swiveling wingtip control surfaces in action here, with the right side one highly deflected. Airshow China 2022: #China displays thrust vectoring engineshttps:// #airshowchina2022 #airshow #airdefence — Janes (@JanesINTEL) November 14, 2022 With each passing week, we are getting more and more detailed imagery of Shenyang's tailless stealth fighter, just as expected. If the flights continue, we should have a much better understanding of the aircraft's observable features by summer. Contact the author: Tyler@

China's New KJ-700 Multi-Intelligence Radar Plane's Interesting Features
We have gotten a new look at China's enigmatic KJ-700 airborne early warning and control (AEW&C) aircraft in service with the People's Liberation Army Navy (PLAN). This latest addition to China's rapidly proliferating family of AEW&C platforms remains somewhat mysterious, although it appears to be something of a 'multi-intelligence' aircraft, combining both airborne radar as well as an array of electro-optical and infrared sensors, likely intended to track targets across air, sea, and potentially land domains. You can read our previous in-depth analysis of China's multi-layered and fast-growing AEW&C fleet here, with the KJ-700 being a new addition to the force, apparently now in both PLAN and People's Liberation Army Air Force (PLAAF) service. The photo in question depicts the PLAN's KJ-700H version of the aircraft, apparently shown in flight for the first time. It shows the aircraft's extensive sensor suite, with the familiar rotodome on the top of the fuselage complemented by multiple other antennas and fairings. On the sides of the rear fuselage are prominent rectangular-shaped fairings, thought to contain additional side-looking airborne radar (SLAR) in the form of active electronically scanned array (AESA) antennas. There is also evidence of an array of electro-optical windows in the 'thimble' nose cone. Further sensors are fitted on the wingtips and in the tail cone. Not visible in this view is the satellite communications (SATCOM) antenna mounted on top of the rotodome. Reports of the KJ-700's existence emerged in mid-2023, with the aircraft at that time rumored to have the alternative designation GX-16, making it the 16th member of China's Gao Xin (meaning High New) series of special-mission intelligence-gathering and surveillance aircraft. The apparent first prototype of the KJ-700 was identified in satellite imagery of the Shenyang Aircraft Corporation (SAC) airfield in December 2020. By June 2023, another two KJ-700s had been spotted in satellite imagery. The KJ-700H version for the PLAN was first sighted in June of last year, when it was reported that the aircraft had entered service at a base in northeastern China, facing South Korea and Japan. Well … according to some rumours, the PLAAF's next-gen AEW platform – successor to the KJ-500 and complement to the larger KJ-3000 – will be named KJ-700. Interesting are the changes at this site: in the middle is supposed to be the KJ-3000's radar right the KJ-700's one. — @Rupprecht_A (@RupprechtDeino) December 17, 2023 When first revealed, it was anticipated that the KJ-700 would be China's next-generation 'medium' AEW&C aircraft, perhaps as a successor to the KJ-500 series. In the past, we have discussed how these smaller types of AEW&C platforms, in particular the turboprop-powered KJ-200 and KJ-500 series, are especially well suited to operations from more dispersed and even austere bases. It's no surprise that they regularly appear at some of China's island outposts, as well as operating routinely in the highly strategic Taiwan Strait. Like the KJ-500, the KJ-700 is based on the airframe of the Y-9 transport, a much-modernized version of the Y-8, itself a Chinese copy of the Soviet-era An-12. Characteristics of the Y-9 include uprated WJ-6C turboprops driving six-blade high-efficiency propellers. The rotodome of the KJ-700 is thought to contain a pair of distributed aperture radar (DAR) antennas, operating in different bands, in a similar arrangement to that found on the carrier-based KJ-600 AEW&C aircraft. This radar, as in earlier AEW&C platforms, is chiefly used to scan for enemy aircraft and missiles, over large swathes of airspace, allowing friendly interceptors to be vectored against them. An elevated 'look down' capability like this means that it can spot low-flying aircraft and missiles that would otherwise be shadowed by the horizon or terrain for surface and land-based radars. Meanwhile, the combination of the fuselage-mounted SLAR arrays and long-range electro-optical/infrared sensors suggests a multi-intelligence function. These sensors could be used for sea or ground surveillance, even if in a secondary role after airspace surveillance. Putting AEW&C as well as broader, multi-domain intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) capabilities into a single platform would make for a highly flexible asset. The KJ-700's electro-optical/infrared suite reportedly includes large-aperture CCD cameras, imaging infrared cameras, and a powerful laser rangefinder. Putting an infrared sensor on an AEW&C platform isn't an entirely new concept. Such a sensor should be especially useful for identifying targets visually at long range, but the electro-optical/infrared suite could also be well adapted to detecting aircraft with low-observable characteristics. In terms of surveillance, a powerful electro-optical sensor system would also be able to investigate objects on the surface, especially in the maritime domain, after being cued by the radar. It could also be used used to support test activities, including tracking missile launches. Other missions for the KJ-700 could include command and control (C2) as well as communications networking, especially valuable over the long distances in the Indo-Pacific theater. Overall, the fact that China has introduced yet another AEW&C platform fits within its established doctrine of developing a range of different solutions to meet different aspects of this mission, as well as to keep pace with the expected types of threat. Chinese AEW&C aircraft now do much more than keep watch over airspace and vectoring interceptors to respond to incoming fighters and bombers. As well as using their radar sensors for what was traditionally their primary task, these platforms are now much more than radar planes, with ESM suites that can passively detect and triangulate radio frequency emissions over long distances. In the case of the KJ-700 specifically, if this is indeed a multi-intelligence aircraft, it is likely tailored to the kinds of missions that might be expected during a future conflict between China and the United States. The KJ-700 would appear to be well suited to supporting operations in which China projects power over considerable distances, including into the highly strategic South China Sea. In this context, KJ-700s operating from smaller island and reef airstrips could play a vital role in detecting hostile aerial activity, not only by crewed fighters — including low-observable ones — but also drones and missiles that could otherwise pose a challenge for existing aerial surveillance systems. Meanwhile, the startling pace of development in China's AEW&C sector is one highlight of the unclassified version of the latest annual Pentagon report to Congress on the country's military, released last December. 'Production and deliveries of the KJ-500 — the PRC's most advanced AEW&C aircraft — continued at a rapid pace, joining earlier KJ-2000 Mainring and KJ-200 Moth variants,' the report notes. 'These aircraft amplify the PLAAF's ability to detect, track, and target threats in varying conditions, in larger volumes, and at greater distances. It extends the range of the PLA's IADS [integrated air defense system] network. Furthermore, the PRC has produced at least one KJ-500 with an aerial refueling probe, which will improve the aircraft's ability to provide persistent AEW&C coverage.' Whatever the precise role of the KJ-700, the aircraft now appears to be in service with both the PLAAF and the PLAN as one of a growing number of AEW&C platforms now in Chinese service. With at least 60 fixed-wing types now in AEW&C service, Beijing not only operates a notably large — and growing — force of radar planes but also continues to develop these aircraft with various different characteristics and specializations.
