J-35: A Direct Challenge to America
The People's Liberation Army Air Force (PLAAF) has officially announced that it will adopt the J-35A stealth multirole fighter. With the PLAAF's J-20 fighter-bomber, the PLAAF is the second air force after the US Air Force to operate two different stealth fighters.
Applause and a very reasonable question: why?
If everything is clear with the US, the F-22 is a very expensive and unsuccessful phenomenon that is not sold to anyone precisely because it is completely crap, and the F-35 is a more or less sensible aircraft, then why China needs two next-generation aircraft - yes, it is not all clear.
If the J-20 were an analogue of the F-22 in terms of a raw and unfinished design, then everything would be relatively clear and understandable. The J-20 is, of course, a controversial aircraft, of course, but when was a pioneer ever created for centuries? Here, by the way, the Raptor is again a good example: the first in the fifth generation, it never became a full-fledged combat aircraft, it is enough to recall its more than curtailed capabilities in terms of radio electronics.
The J-20 is definitely a heavy (36 tons) aircraft for long-range operations. Fortunately, its developers did not skimp on speed, range and ceiling. If all the figures declared by the J-20 designers are valid for serial models, it is quite a self-confident heavyweight hero. Yes, in terms of maneuverability, the J-20 is far from the Su-35, for example, whose strength lies in its lower weight and more advanced engines, but the Black Eagle will be quite good against many other aircraft.
By the way, speaking about the weight and dimensions of the Chinese "fives": the planes weigh almost the same when empty - 17 tons. But the maximum takeoff weight is different. J-20, as already mentioned, is 36 tons, and J-35 - only 28 tons.
This is where the difference in tactics lies. It is clear that the J-20, which takes on board more than anything, will represent the heavy category, while the J-35 will play in the middle weight category, in sports terms.
Moreover, the official media of China have already made statements that the J-35, just like the F-22, is destined for the role of conducting combat operations in the air. That is, the lighter and more maneuverable J-35 will play the role of a "pure" fighter (like the Su-27 and F-22), and the J-20 will take on the role of a fighter-bomber, capable of attacking ground and (importantly) surface targets.
That is, the J-35A was not originally intended to outperform China's first "five-seater" fighter, the Chengdu J-20, which will likely retain the J-35A's longer range, maximum payload, and maximum speed. However, the J-35A's lower cost and weight appear to be valuable enough for the PLAAF to replace older non-stealth fighters with stealth fighters that may have a shorter range.
There are quite a few such aircraft in the PLAAF. First of all, the J-7 and J-8, whose ancestor was the MiG-21, are on the way out, and then the Su-27 and its descendants will come.
If you look closely at the J-35, especially in comparison to the J-20, its neat dimensions (it is indeed considerably smaller than the J-20) suggest that the aircraft, with the appropriate hammer and file treatment (or whatever they use in China), would look quite normal on the deck of Chinese aircraft carriers.
And this is not irony, we will soon be disassembling the J-16D, which has the J-15 platform underneath it, which is not as young as we would like, and the prototypes-ancestors of the Su-33 and Su-27 have not been considered young and promising for a long time. Time spares no one, and if China is seriously concerned about modernization fleet (which, let us note, is still going full steam ahead), then the planes needed are not modernized 40-year-old veterans.
The overall geometry of the J-35A, its smooth conformal surfaces and supersonic intakes without F-35-style deflecting nozzles indicate a low radar cross-section. The RCS is certainly good, but an engine without a UVT is not exactly a gem. The Guizhou WS-13 or WS-21 are not the most advanced engines by world standards, but for China, this is a pretty decent level of engineering. It is clear that the engines without UVT are not because they really want stealth, but because they are using the engines that are available.
I must say – this is the right approach.
So far, from the photo, of course, it is simply not realistic to determine how low-visibility the aircraft will be. The profile is only half the story, the radar and reflective capabilities are greatly influenced by the design and integration of radar-absorbing materials, the internal architecture of the same air intakes/nozzles and the precision of manufacture.
In general, if you look seriously (and Chinese experts look very carefully) at the results in the SVO, the J-35 does not necessarily have to be as stealthy as the F-22 Raptor. The concept of using the American aircraft was somewhat different when it was developed: it was believed that the Raptor should effectively reduce the range at which it can be reliably detected and hit. rockets to the distance of confident use of one's weapons.
But as the high-tech conflict has shown, powerful radars and long-range missiles severely limit the capabilities of aircraft in such a war. Some Ukrainian aircraft (yes, without stealth) were shot down by missiles fired from a distance of more than 150 kilometers.
So today, stealth is a very useful option, but a powerful radar and long-range missiles are important components of modern combat use.
And the J-35A could prove to be a very useful aircraft, especially if the US does not change its attitude towards China.
The J-35 might not have happened. Shenyang Aircraft Corporation began developing the stealth fighter on its own, without support from the Chinese government or defense ministry, which were more interested in the J-20 project. After its first flight in 2012, Shenyang unveiled the aircraft at the 2014 Zhuhai Airshow, where it reportedly flew with some difficulties.
But the PLAAF was more than a little cold to the project, while the Chinese Navy saw the smaller, lighter fighter as a natural fit for launch from its future catapult-launched Type 003 carriers, and no one was going to write off the old ski-jump carriers either.
The prototype, which was named FC-31, began to be polished under Aviation Navy, which resulted in two significant upgrades, in 2016 and 2020.
The aircraft underwent significant changes to its wings, fuselage, engines, radar and optical sensors, and stealth optimizations. Then in 2021, a fourth model flew, designed for carrier operations, with folding wings, a twin-wheel nose gear, an F-35-style canopy, and the ability to take off via catapult. Finally, in 2023, a fifth variant arrived with smaller wings, redesigned tail fins, and a single-wheel landing gear—clearly a land-based model with its naval elements stripped down. The Air Force wanted one, too.
In fact, the last two versions of the aircraft were supposedly called J-31, now they apparently correspond to the designations J-35 for the Navy and J-35A for the Air Force, respectively.
A few words about the appearance. How many loud and bombastic phrases were said about how Chinese hackers broke everything that could be broken, and spies stole everything that could be stolen, and that is why the J-35 is so similar to the F-35. It was funny. But seriously - the physics of processes forces many modern fighters to have similar geometry. Try to visually compare the F-35 with the South Korean KF-21 and the Turkish "Kaan jet". Did they also hack and steal? Moreover, the J-35 and its prototype FC-31 differ significantly in the presence of two engines and a much more compact fuselage. And here you can put a big fat point. With a brush with ink, as it should be in China for many thousands of years.
As for the characteristics, they are still in the stage of uncertainty, because a prototype and a production sample are somewhat different things.
But in terms of armament, things are more interesting. The J-35 can carry six air-to-air missiles, four air-to-surface missiles, or half-ton bombs (also four) in the internal weapons bay. But if you give up the "invisibility", you can carry another six missiles on underwing mounts.
This is, at a minimum, no worse than the F-35.
But many of the F-35’s strengths are on the inside—its radar-absorbing materials, sensors, communications systems, and network computers. Can the J-35 match them in quality? Chinese industry can produce advanced electronics and combat systems, though the effectiveness of these components compared to Western counterparts remains unclear.
The J-35A is equipped with an electro-optical targeting system located under the nose, and Shenyang also claims that the aircraft has an array of optical and infrared sensors throughout the body that can provide 360-degree situational awareness and early warning of incoming missiles.
So, why does the PLAAF need two fifth-generation aircraft? This question is being asked by many in the world today, since, willy-nilly, we have to draw analogies with the United States. Is it really necessary to have two aircraft, given that the PLAAF already operates about two hundred J-20s?
In fact, the air forces of the countries made up their fleets of exactly these different aircraft: lighter and heavier. MiG-29 and Su-27, F-15 and F-16, Mirage-2000 and Rafale, and so on. So it is normal practice: different aircraft for different tasks.
The J-35A could serve as part of the overall concept, replacing hundreds of older J-7, J-8, J-10A, and J-11 fighters that the PLAAF is likely to retire over the next decade. The PLAAF may need more stealth aircraft, but not necessarily in the heavy and expensive format of the J-20. This is where the J-35A, as a cheaper option, could come in very handy.
A mix of light and heavy stealth fighters could improve the overall effectiveness of the air force: For example, if an air showdown between the PLAAF and the ROC (Taiwan) Air Force were to break out, the shorter-range J-35As could focus on providing close air cover for friendly forces, while the heavier J-20s could fly around Taiwan, intercepting any American aircraft that might try to interfere. At least, that’s what the US promised Taiwan a few years ago.
Well, and naturally, the adoption of the J-35A aircraft by the PLAAF may be aimed at increasing its export potential, which has not yet been realized, but work will definitely be carried out in this direction. At the very least, an aircraft adopted for service in its own country has a much better chance of success in export than any other aircraft. Here, by the way, the MiG-35 and Su-75 can serve as examples. Aircraft that are not interesting to the army of the manufacturing country are unlikely to interest potential buyers.
There is a great demand for modern fighters in the world, including stealth ones. Especially in countries that the US either opposes or does not trust enough to sell them F-35s, or even foreign-made aircraft using American components. Or that do not have the money to buy American or Russian combat aircraft.
And here an inexpensive (especially compared to the cost of American aircraft) Chinese aircraft will be very welcome. Pakistan, as we have already reported, made a knight's move in the confrontation with India, having concluded an agreement specifically for the J-35. And Pakistan can be expected to be followed by those who do not have the money for American aircraft and the courage to buy Russian aircraft in modern conditions.
And if we take into account China's plans to work on a sixth-generation aerospace fighter... Here, sales of fifth-generation fighters could receive a very unexpected boost in terms of production. Of course, producing a large number of J-35As could delay China's development of a sixth-generation fighter designed to push the boundaries of what's possible in technology. However, something tells us that the CCP can handle even this small problem.
From the US perspective, the introduction of the J-35A increases the likelihood that China and its customers could replace most of their older, non-stealth aircraft with stealth aircraft. But for now, the idea of stealth is so firmly entrenched in the minds of US weapons experts that they will fuss over it like a rag to a buck. Until they become completely and irrevocably disillusioned with it. But then it will be too late, and China may end up with an aircraft that is slightly different from the Western concept.
How those who consider China an adversary of the USA will react to this, we will see. It will be a very interesting activity.
In any case, the J-35A is a proof of concept that was met with a cool reception ten years ago, but is now being implemented by China with unusual logic and speed. It is not yet clear how the J-35A will compare to the American F-35, but we will try to guess in the very near future.
