(DEFENCE SECURITY ASIA) — China has officially revealed that the radar cross section (RCS) of its new-generation J-35 stealth fighter is smaller than the size of a human palm, a disclosure that underscores Beijing’s rapid advances in stealth technology and fifth-generation aircraft design.

According to state-run Global Times, citing a detailed China Central Television (CCTV) report broadcast on Sunday, the minuscule RCS is made possible by the J-35’s unique fuselage shaping combined with the application of advanced metamaterial coatings — technologies that Chinese officials claim are domestically developed and exclusive to China.

The announcement represents one of the most significant public acknowledgments to date of the J-35’s stealth credentials, placing the aircraft in the same elite category as the U.S. F-35 Lightning II and F-22 Raptor in terms of low observability.

Defence analysts argue that such a revelation is not accidental, but rather a calculated signal aimed at both regional adversaries and the international defence community, highlighting China’s growing confidence in its aerospace industry’s capability to rival Western fifth-generation fighters.

Wang Ya’nan, the chief editor of Beijing-based Aerospace Knowledge magazine, told Global Times that an RCS equivalent to a human palm, roughly comparable to that of a sparrow, should be considered “very small” for a combat aircraft of this size and class.

“Such a value indicates the J-35’s stealth capability is at a world-class level,” Wang stated, noting that the reduced RCS means the aircraft could penetrate advanced air defence systems undetected until it is dangerously close to its target.

This capability could fundamentally reshape airpower dynamics in the Indo-Pacific, as nations like the United States, India, and Japan rely heavily on layered air defence networks such as the Patriot PAC-3, S-400, and Aegis-equipped destroyers to counter aerial threats.

If Chinese stealth fighters are indeed able to evade detection until within lethal missile range, Beijing would gain a decisive first-strike advantage in any potential conflict scenario over contested regions such as the Taiwan Strait or the South China Sea.

China’s decision to publicly disclose such an ultra-low RCS value also indicates a shifting strategic calculus in Beijing, suggesting that the J-35 may be nearing an operational maturity level where its stealth characteristics can be confidently showcased as a deterrent tool rather than a guarded state secret.

The revelation further pressures Indo-Pacific air forces to reassess the survivability of their airborne early-warning platforms, tanker fleets, and high-value command-and-control aircraft, all of which depend on extended detection ranges that may now be compromised by a new generation of Chinese low-observable fighters.

Analysts also warn that if the J-35’s metamaterial-based stealth coating proves highly durable in real-world deployments — including maritime, carrier-based, and tropical environments — it could provide China with one of the most cost-efficient stealth maintenance regimes in the world, challenging the long-held U.S. advantage in stealth sustainment.

More critically, the combination of a palm-sized RCS with modern Chinese air-to-air missiles such as the PL-15 and emerging PL-21 dramatically expands the J-35’s engagement envelope, potentially enabling the aircraft to strike first against even the most sophisticated Western fighters before being detected on radar.

Strategic Timing: The Fujian Carrier Connection

The revelation of the J-35’s RCS came just days after the People’s Liberation Army Navy (PLAN) announced a major milestone: China’s third aircraft carrier, the Fujian (Type 003), had successfully hosted its first catapult-assisted takeoff and arrested landing trials.

The September 22 announcement confirmed that the electromagnetic catapult-equipped supercarrier conducted training involving three aircraft types — the J-15T heavy fighter, the KJ-600 airborne early warning aircraft, and crucially, the J-35 stealth fighter.

The pairing of an advanced stealth fighter with an electromagnetic catapult system is strategically significant, as it allows the PLAN to project a level of naval airpower comparable to the U.S. Navy’s F-35C Lightning II deployed from nuclear-powered carriers.

By publicly linking the J-35’s stealth breakthrough with the Fujian’s trials, Chinese state media underscored the synergetic relationship between platform and carrier, reinforcing the message that China’s blue-water navy ambitions are now backed by world-class aviation technology.

 

J-35: Bridging Medium and Heavy Fighter Categories

CCTV’s report went beyond stealth to highlight key performance parameters of the J-35.

According to the state broadcaster, the carrier-based stealth jet has a maximum takeoff weight of nearly 30 tons and is powered by two medium-thrust engines fully developed within China’s aerospace sector.

Experts note that while officially designated as a medium-sized fighter, a 30-ton maximum takeoff weight pushes the J-35 into the lower spectrum of the heavy fighter category.

Combined with electromagnetic catapult launches, this weight class allows the aircraft to take off fully loaded with munitions and fuel — extending range, increasing payload options, and enhancing combat endurance compared to ski-jump-launched fighters like the J-15.

Such characteristics position the J-35 as a true multi-role stealth strike fighter, capable of long-range maritime interdiction, air superiority missions, and deep strike operations across the First and Second Island Chains.

The J-35’s reliance on twin medium-thrust engines of fully domestic origin represents another milestone for Beijing’s aerospace ambitions.

China has long struggled with engine independence, relying heavily on Russian-made powerplants for platforms such as the J-10 and JF-17, while indigenous programs like the WS-10 and WS-15 faced years of delays.

The announcement that the J-35 is powered by Chinese-developed engines signals a significant step toward strategic autonomy in aviation, insulating Beijing from potential sanctions or supply disruptions.

If these engines prove reliable, the J-35 would mark a clear break from China’s historical dependence on Russian propulsion technology and position AVIC as a peer competitor to Western and Russian aerospace primes.

Modular Variants for Air Force and Navy

The J-35 series is not confined to naval aviation.

The CCTV report reminded viewers that the J-35 is the carrier-based derivative of the J-35A, a multirole stealth fighter designed for the PLA Air Force.

First unveiled at Airshow China 2024, the J-35A demonstrated China’s intent to field a family of stealth fighters across services, with modular avionics, sensor suites, and design elements allowing for both air force and navy variants.

This concept mirrors the U.S. F-35 program, which developed the A, B, and C variants for different services under a single airframe family, creating efficiencies in logistics, maintenance, and training.

Wang Yongqing, chief designer at the Shenyang Aircraft Design and Research Institute under AVIC, emphasized the advantages of the multi-variant strategy in an earlier interview with Global Times.

“Many of our research achievements can be applied across different variants, such as sensors, onboard equipment, and avionics systems. This development model has significantly reduced both the costs and time required for fighter jet development,” he explained.

The approach not only accelerates deployment timelines but also allows the PLA to maintain a larger fleet size while reducing maintenance costs — a critical factor for sustaining long-term readiness across a vast geography.

By developing both naval and air force versions in tandem, China maximizes its return on investment while ensuring interoperability across the services.

Geopolitical Implications of World-Class Stealth

The disclosure of the J-35’s sparrow-sized RCS carries profound strategic implications.

For Taiwan, the announcement intensifies pressure on its already strained air defence network, which relies on a mix of Patriot PAC-3 systems, U.S.-supplied F-16Vs, and French-built Mirage 2000s.

For Japan, the J-35 represents a looming challenge to its F-35 fleet, as Tokyo doubles down on its fifth-generation fighter integration to defend the Senkaku/Diaoyu Islands and broader East China Sea.

For the United States, the revelation adds urgency to ongoing programs such as the Next Generation Air Dominance (NGAD) fighter, which Washington hopes will secure air superiority into the 2030s and beyond.

In South Asia, India is likely to view the J-35’s stealth breakthrough with alarm, as New Delhi has invested heavily in Rafale jets and is negotiating for Su-57E stealth fighters from Russia while simultaneously accelerating its indigenous Advanced Medium Combat Aircraft (AMCA) project.

Redefining Carrier Strike Group Balance

Perhaps the most significant impact will be felt in naval strategy.

With the J-35 joining the Fujian’s air wing, China’s carrier strike groups will boast true fifth-generation capabilities for the first time.

This development narrows the qualitative gap with U.S. Navy carrier air wings, which deploy the F-35C aboard nuclear-powered supercarriers like the USS Gerald R. Ford.

While China’s carriers remain conventionally powered, the combination of electromagnetic launch systems and stealth aircraft fundamentally alters the tactical calculus in potential flashpoints such as the Taiwan Strait, the South China Sea, and the Western Pacific.

Carrier-based stealth fighters would allow China to conduct power projection and anti-access/area denial (A2/AD) operations far from its shores, challenging U.S. and allied dominance in the Indo-Pacific.

A New Era of Chinese Stealth

The revelation that the J-35 stealth fighter’s radar cross section is smaller than a human palm is more than a technical detail.

It is a strategic statement by Beijing that China has not only caught up with the world’s leading stealth technologies but is ready to deploy them on a large scale from its newest carriers.

With domestic engines, modular variants, and a design philosophy emphasizing affordability and mass production, the J-35 series could become the backbone of China’s stealth fighter fleet across both naval and air force domains.

As the Fujian progresses toward full operational capability, the J-35’s integration will redefine the balance of power in Asia’s skies and seas, forcing adversaries from Washington to New Delhi to recalibrate their air defence and naval strategies.

In short, the palm-sized radar cross section of the J-35 may appear small, but its implications for global military aviation are enormous.

The aircraft’s ability to integrate advanced datalink networks, sensor fusion systems, and electronic warfare capabilities means its low observability is only one component of a broader multi-domain operational advantage.

If mass-produced in significant numbers, the J-35 could overwhelm regional air defence networks through sheer saturation of stealth aircraft, presenting a challenge that even the most advanced radar and missile systems would struggle to counter.

Its emergence also underscores China’s long-term intent to compete with the United States not only in regional theatres but also in global arms export markets, where the J-35 could become a cost-competitive alternative to the F-35 for nations aligned with Beijing.

For regional militaries, particularly in Southeast Asia, the arrival of the J-35 represents a disruptive leap that could compel accelerated investment in counter-stealth technologies such as quantum radar, low-frequency radar, and passive detection systems.

Ultimately, the J-35 is more than just a stealth fighter — it is the embodiment of China’s determination to erode Western aerospace dominance, reshaping not only the Indo-Pacific balance of power but also the global trajectory of fifth- and sixth-generation air combat. — DEFENCE SECURITY ASIA
