J-35A Stealth Fighter

China’s J-35A Air Force Stealth Fighter

China's J-35A stealth fighter jet displayed along with anti-radiation missile at Changchun Air Show. A scale model of the J-35A stealth fighter jet was on display together with several types of missiles at the booth of the Aviation Industry Corporation of China during the Air Force Open-day Activities and Changchun Air Show in Changchun, Northeast China's Jilin Province recently. This suggested that the J-35A could potentially carry out electronic warfare missions and strike hostile radar sites, an expert said. China’s J-35A stealth fighter is the land-based cousin of the carrier-oriented J-35, both rooted in Shenyang’s FC-31 lineage. Following are the some of the important points:-

Compared with the F-35, China is equally matching the software maturity, mission-system fusion and sustainment scale, kinematics and stealth margins.

Beijing wanted it to complement the heavier J-20: a more numerous, medium-weight, low-observable fighter which plugs into PLA kill chains and deter US and allied airpower.

Public debuts and test imagery since late 2024 show a twin-engine, EOTS-equipped airframe with internal weapons bays and next-gen sensors; official performance data remain sparse.

The J-35A didn’t start life as a centrally anointed flagship. A decade ago, Shenyang’s FC-31/J-31 appeared as a largely company-driven prototype, a hedge on future export sales and a potential domestic slot if Beijing ever wanted a lighter stealth fighter alongside the heavyweight J-20. The airframe evolved in fits and starts: new intakes, revised platform, reworked canopy and bays. Then the Chinese navy’s carrier ambitions crystallized, and Shenyang spun a navalized variant toward catapult operations. That carrier path (today’s J-35) gave the design family a customer and a mission. Alongside air-to-air missiles such as the PL-10E, PL-15E and PL-12AE, the LD-8A anti-radiation missile was also featured in the exhibition of the J-35A's arsenal. If you already fly the J-20, why add another stealth fighter? The logic is force-design, not vanity. The J-20 is a big, long-range thoroughbred with a premium radar and growing engine power. It is also expensive. The PLAAF doesn’t just need long-range interceptors; it needs a multi-role stealth fighter which can hunt aircraft and cruise missiles, escort high-value assets, and work near contested coastlines where fuel, maintenance and runway considerations favour a smaller airframe.  A medium-weight, twin-engine stealth jet offers more tails on ramps and more sorties in less expensive mode, which matters for a military planning to fight under a dense umbrella of surface-to-air missiles, long-range radar, and data linked shooters. There’s a political layer: fielding two different stealth fighters puts China in a club previously occupied by US. Even if raw capability isn’t parity, the optics shape regional perceptions and procurement debates from Tokyo to Taipei to Canberra. Chinese sources have framed the J-35A as a “kill-chain” fighter, an aircraft which not only shoots, but also discovers, classifies and cues other weapons. Think counter-stealth surveillance of inbound threats, networked targeting for ground and maritime strikes, and cooperative engagements with SAMs, ships, and other aircraft. In other words, less lone-wolf, more quarterback.

Wang Ya'nan, chief editor of Beijing-based Aerospace Knowledge magazine, explained that an anti-radiation missile is a type of weapon which specifically targets radar installations, which radiates electromagnetic waves. Anti-radiation missiles can track and destroy the radiation source, but the use of anti-radiation missiles often requires electronic warfare aircraft with powerful sensors to detect the radiation source first. The J-35A is the land-based fork of that story, tweaked for PLAAF needs instead of catapult decks: different nose gear, wing geometry, vertical tails and avionics/software tuned for air-force operations. Public showings in late 2024 offered the first close look at a jet which had long been rumoured but rarely seen; since then, appearances and official hints have filled in outlines without surrendering hard numbers. This is deliberate. China’s aviation complex has learned to reveal just enough, shape, role and theatre, while keeping performance and software detail behind the curtain. Stealth is the hardest piece to judge from photos. A clean platform is necessary, not sufficient. Materials, coatings, panel fit and seal management at tempo are where programs are exposed. Here China is improving, each generation of Chinese stealth jets shows tighter manufacturing tolerances and more sophisticated surface treatments than the last.

The side-by-side display of the J-35A and the anti-radiation missile suggested that the J-35A could have a dedicated electronic warfare variant, or the J-35A can work together with electronic warfare aircraft in electronic warfare missions. Seen up close, the J-35A presents a modern stealth silhouette: internal bays, a blended fore body, canted tails, edge alignment, serrated access panels and a chin-mounted electro-optical/IR turret broadly analogous in placement to the F-35’s EOTS. The naval sibling features folding wings and a catapult launch bar, while the air force J-35A omits these, adopting a single-wheel nose gear and a smaller wing for improved land-based performance. China's plans to use it includes different roles. In this ecosystem, a medium-weight stealth fighter can play three following complementary roles:-

Carrying a small internal load for time-sensitive targets while acting as a sensing node that enables long-range fires from ships, coastal batteries or other aircraft.

Hunting low-observable aircraft and cruise missiles that slip past the outer belt, using high-gain radar modes, IR sensors, and data linked tracks from ground and airborne partners.

Flying cover for tankers, AEW&C, and bombers with less penalty to numbers than tasking the heavier J-20 for every sortie.

Because the PLAAF favours mass and persistence, a “good-enough, numerous” stealth fighter paired with a smaller but exquisite J-20 cadre makes strategic sense. The J-35A is the mass half of that equation. Because the J-35A is new, its track record comes mostly in glimpses: taxi runs, short flight demos and tightly curated media moments at Zhuhai; satellite and telephoto proofs of additional prototypes; and quotes from Chinese engineers sketching how the jet would fit a counter-stealth, networked air-defence concept. Western trade press and wire services corroborate the basics: the public debut timeline, the split between carrier and land variants, and China’s intent to field the type in meaningful numbers. What we still don’t have is the real data which make or break a fleet: mission-capable rates, software stability in the field, sensor fusion quirks and the bruises that come from large-force exercises. The trend surface years after a type enters regular service. Until then, the best reading is that the J-35A is transitioning from prototypes to initial units, while the carrier variant feeds the navy’s air wing ambitions. Expect months (and likely years) of iterative updates to radar modes, EW techniques, and data link behaviour before anyone can call the jet “mature.”

Imagery and reporting suggest continuing propulsion work, from interim engines in early prototypes to an indigenous WS-19-class path for production, but definitive thrust ratings, fuel fractions and radar aperture sizes remain guarded. Engines are the long pole in every fifth-gen tent. Reporting points to a pathway toward a WS-19-class power plant for the air-force variant and WS-21/WS-13-series work for prototypes. If those engines deliver reliable thrust and thermal margins, Beijing can field the J-35A in useful quantities even if peak performance trails Western benchmarks. Likewise, weapons fit will lean on China’s modern air-to-air missiles, notably PL-15-class beyond-visual-range rounds and PL-10-class high-off-bore sight weapons, carried internally to preserve signature. Precision surface attack from the bays would round out the role set. A stealth fighter that is good enough to fuse, good enough to hide, and cheap enough to field in numbers is dangerous in a region where the distances are long and the timelines are short.

The LD-8A anti-radiation missile displayed at the air show has a similar design to the PL-15E air-to-air missile, including their size and aerodynamic shape. Against the F-22, the comparison tilts toward kinematics and signature. The Raptor’s supercruise, thrust-vectoring, and extreme emphasis on front-aspect stealth were designed for air dominance against peer fighters and dense SAM belts. If a fight devolves to energy manoeuvring, the F-22 holds the cards. Where the J-35A could complicate a Raptor’s day is numbers, networking, and angles, arriving from unexpected vectors with long-range missiles cued by off board sensors, or acting as silent spotters which force Raptors to defend instead of dictate. In practice, a future US–China air battle would be larger than any two types: F-35s, F-15EXs, EA-18Gs, E-7s, MQ-25s, submarines, and surface shooters on one side; J-20s, J-35As, KJ-500s, H-6 variants, unmanned decoys, and layered SAMs on the other. The J-35A makes that Chinese web tighter. It does not make the F-22 obsolete.

LD-8A anti-radiation missile could be a variant of the PL-15 series missile with an alternate seeker that receives and tracks a specific electromagnetic wave frequency. Based on the PL-15 platform and judging from the China's capabilities in electronic industry, this type of missile should be at a world-leading level. The F-35 is the wrong yardstick in one way and the right one in another. On paper the airframes rhyme, internal bays, stealth shaping, a chin EO sensor, and emphasis on networking. Where the F-35 differentiates itself is less aerodynamic than informatic: thousands of jets, millions of flight hours, decade-plus of software sprints, and a sustainment ecosystem that, despite its headaches, supports a vast, multinational fleet. The sensor fusion story is crucial. It’s not just the radar or EOTS; it’s how tracks from every sensor and partner become a single, stable picture across a four-ship, a squadron, and a strike package. China can and will write powerful code, but software maturity is earned at scale with brutal feedback from exercises, deployments and coalition ops. Training pipelines, tactics development, EW libraries, mission-data reprogramming, and secure data links are where fifth-gen lives day-to-day. If the J-35A is to rival the F-35 in effect, the gap to close is less about wing loading and more about firmware. On the other hand, stealth jets are maintenance-intensive; coatings and panel alignment don’t survive sloppy processes. The F-35 community has spent years learning how to keep low observability intact on rainy tarmacs with crews rotating at odd hours. The PLAAF can replicate much of this, but it will take time, and the learning curve will be steep and public. A few markers will tell you whether the J-35A is maturing:-

Trade-press notes about new radar modes, EW updates and mission-data reprogramming pipelines mean the software machine is spinning.

When production jets fly with stable indigenous engines across climates and tempos, the program has cleared a major hurdle.

A visible division of labour with the carrier-borne J-35 and shared tactics across services, would show a mature joint concept, not just parallel procurement.

The J-35A isn’t a clone of the F-35 or a peer to the F-22. It doesn’t need to be. It needs to be available, survivable, and networked, and put in enough numbers to force US and allied planners to assume stealth opponents at scale. On that score, China’s decision to adopt a second stealth type looks coherent: the J-20 remains the long-reach spear, while the J-35A becomes the everyday stealth fighter that improves air defences, escorts critical assets and quietly sets up shots for others. The open questions are the important ones: engines, software maturity, sustainment discipline, and training at scale. If Beijing closes those gaps, the J-35A won’t just be a headline jet at air shows; it will be the plane which makes the air picture noisier, the targeting chains faster and the margin for error narrower from the Yellow Sea to the Philippine Sea. It also matters for rivals around the world.
