(DEFENCE SECURITY ASIA) — In a move that underscores Beijing’s unrelenting push toward fifth-generation air supremacy, China on October 5, 2025, unveiled never-before-seen footage from inside the production hangars of its J-35 and J-35A stealth fighter jets.

The revelation came through China Military Bugle, an official media platform associated with the People’s Liberation Army (PLA) News Media Center, marking a historic moment in Chinese military transparency and technological assertion.

 

The short but revealing footage, amplified across Weibo and X (formerly Twitter), provided a rare glimpse inside Shenyang Aircraft Corporation (SAC)—the heart of China’s northern aerospace industry and the birthplace of the nation’s most ambitious stealth designs.

Within seconds, the world saw something extraordinary: rows of partially assembled stealth airframes, technicians in protective suits working on metallic-green fuselages, and precision robotic arms moving across the assembly line in what appears to be a coordinated ballet of next-generation manufacturing.

In parallel with the imagery, military analysts noted that the layout and workflow within the hangars closely mirrored the modular digital-manufacturing processes adopted by Lockheed Martin for the F-35 program, indicating that China has successfully transitioned to an integrated “Industry 4.0” model for stealth aircraft assembly.

Satellite imagery reviewed by Defence Security Asia further corroborated that the Shenyang complex has expanded by more than 35 percent since 2023, with new composite-curing facilities and radar-absorbent material (RAM) laboratories constructed adjacent to the primary production line.

Defence observers also pointed out that the visible automation, robotic riveting systems, and standardized jigs suggest that mass production readiness has already been achieved—an industrial benchmark that moves China closer to sustained serial output similar to Western fifth-generation programs.

For China’s aerospace sector, this was not just another factory video.
It was a statement of arrival.

THE GENESIS OF THE J-35 PROGRAM

The J-35 story began over a decade ago with the FC-31 “Gyrfalcon”, a private venture by Shenyang Aircraft Corporation designed to showcase a potential export-oriented stealth fighter.

In the early 2010s, SAC’s ambitions were overshadowed by Chengdu’s J-20, which secured PLA adoption as China’s first fifth-generation platform.

But the FC-31 project quietly evolved, maturing through extensive wind tunnel testing, foreign airshow demonstrations, and gradual adaptation to PLA requirements.

By the late 2010s, Chinese military planners saw an opportunity: a twin-engine, carrier-capable stealth fighter that could complement the heavier J-20 and extend China’s reach into the maritime domain.

That vision gave birth to the J-35, optimized for deployment on the Type 003 aircraft carrier “Fujian”—the PLA Navy’s first flat-deck CATOBAR carrier equipped with electromagnetic catapults.

Featuring folding wings, reinforced landing gear, and navalized avionics, the J-35 was engineered to take off from short carrier decks and recover under high crosswind conditions, an engineering feat rivaling Western naval standards.

Its land-based counterpart, the J-35A, shares much of the same airframe and avionics but features a single nose wheel and enhanced ground handling, optimized for PLAAF (People’s Liberation Army Air Force) operations.

Together, the J-35 family represents China’s most significant dual-service stealth fighter program, bridging air and sea operations under a unified design philosophy.

INSIDE THE HANGARS: CHINA’S STEALTH ASSEMBLY REVEALED

The 33-second video clip released on China Military Bugle’s official channel was succinct but symbolically powerful.

The footage opened with a caption reading “First Public Unveiling of J-35 Assembly Line,” accompanied by sweeping shots of the SAC production hall in Liaoning Province.

Technicians could be seen inspecting forward fuselage sections, while digital screens along the hangar walls displayed holographic schematics of aerodynamic stress models—hinting at China’s adoption of digital twin technology in fighter production.

At least a dozen airframes appeared visible in various stages of completion, confirming that low-rate initial production (LRIP) is already well underway.

The video also intercut archival footage of the J-35’s carrier tests aboard the Type 003 Fujian, including electromagnetic-assisted takeoffs and precision landings—clear evidence of the fighter’s maturity for naval deployment.

Accompanying subtitles highlighted the J-35’s participation in simulated beyond-visual-range (BVR) combat drills, as well as mock intercepts against “unknown hostile aircraft,” a narrative aligned with the PLA’s focus on anti-access/area-denial (A2/AD) capabilities in the Pacific.

For the first time, global observers could confirm that the J-35 program has transitioned from prototype to pre-operational status, bridging the gap between ambition and reality.

ENGINEERING MARVELS: SPECS, TECHNOLOGY, AND DESIGN

The J-35 and J-35A epitomize a leap in indigenous Chinese aerospace engineering.

Designed with stealth-first architecture, both jets feature diverterless supersonic inlets (DSI) that reduce radar cross-section (RCS) and improve high-speed airflow efficiency.

Their blended wing-body design, serpentine engine intakes, and extensive use of radar-absorbent composite materials are reminiscent of U.S. F-35 Lightning II technology, yet distinctly adapted for Chinese operational doctrines.

The aircraft are powered by the WS-19 afterburning turbofan engines, developed by Shenyang Liming Aircraft Engine Company, capable of producing 13,000 kgf of thrust each—enabling limited supercruise capability at Mach 1.2.

This marks a significant milestone for China, signaling partial independence from Russian engine reliance after decades of using AL-31 and RD-93 powerplants.

The integration of active electronically scanned array (AESA) radar systems, based on gallium nitride (GaN) modules, allows the J-35 to detect and track multiple targets beyond 200 kilometers.

It is also equipped with Distributed Aperture Systems (DAS) and Infrared Search and Track (IRST) sensors that provide full 360-degree situational awareness, fusing data into the pilot’s helmet-mounted display (HMD).

These technologies enable the aircraft to operate within integrated data networks, sharing targeting information with AWACS platforms, unmanned wingmen, and naval combat systems.

THE STRATEGIC SIGNIFICANCE

The unveiling of the J-35 and J-35A hangars is not just an industrial milestone—it is a deliberate strategic message.

For Beijing, the timing is crucial.

The footage emerged only days after China’s National Day parade on September 28, where mock-ups of the J-35 series rolled down Chang’an Avenue, signaling China’s ascent to fifth-generation parity.

The PLA’s intent is unmistakable: to demonstrate that it can now field carrier-borne stealth fighters capable of operating across the Taiwan Strait, South China Sea, and Western Pacific.

For the PLA Navy (PLAN), the J-35 represents an airpower revolution.
It gives China the ability to project low-observable strike packages far from home shores, reducing dependence on land-based aviation assets.

Paired with the Type 003 “Fujian”, the J-35 positions China as the only nation besides the United States to deploy stealth aircraft from CATOBAR carriers—a profound statement in maritime strategy.

For the PLA Air Force (PLAAF), the J-35A complements the heavier J-20, allowing for distributed lethality through mixed formations of heavy and medium stealth fighters.

This combination mimics the U.S. Air Force’s operational pairing of F-22 Raptors and F-35 Lightning IIs, reflecting a sophisticated doctrinal evolution in China’s air combat architecture.

GLOBAL RESPONSE AND ANALYTICAL REACTIONS

Reactions across the global defense community have been swift and divided.

Chinese commentators hailed the hangar reveal as a “milestone of national rejuvenation.”

Military analyst Li Wei asserted that “the J-35 demonstrates China’s transformation from a follower to a leader in stealth aviation,” emphasizing its export potential to Pakistan, Serbia, and possibly Iran.

Western analysts, however, have taken a more cautious tone.

A report by The Diplomat noted that while the J-35 narrows the technological gap with the F-35, challenges persist in engine reliability, coating durability, and sensor fusion stability under combat stress.

The RAND Corporation issued a study in early 2025 warning that J-35 proliferation—particularly if exported to allies—could “erode America’s qualitative airpower advantage by 2030.”

In India, the unveiling has reignited debates over the Tejas Mk2 and Advanced Medium Combat Aircraft (AMCA) programs, with defense commentators urging faster development to counterbalance the J-35A’s regional impact.

Even Jane’s Defence Weekly remarked that the hangar footage “blends real industrial imagery with digital embellishments—propaganda with pixels—but the underlying message of rapid capability maturation is undeniable.”

GEOSTRATEGIC IMPLICATIONS IN THE INDO-PACIFIC

The operationalization of the J-35 carries sweeping implications for the Indo-Pacific balance of power.

For the United States and its allies, it signifies that China can now deploy carrier-based stealth strike groups capable of contesting U.S. air and sea superiority.

The introduction of multi-platform stealth capability—J-20 for high-altitude dominance and J-35 for maritime strike—gives the PLA an unprecedented operational spectrum across air denial, electronic warfare, and deep penetration missions.

The J-35’s presence aboard PLAN carriers in the South China Sea could extend China’s anti-access/area-denial (A2/AD) envelope by over 1,000 kilometers, threatening U.S. carrier strike groups operating from Guam, Okinawa, and the Philippines.

It also complicates the strategic calculus for Japan’s Air Self-Defense Force, which is preparing to induct the F-35B aboard its converted Izumo-class carriers.

The Taiwan Strait emerges as another theater of concern.

With the J-35 and J-35A in tandem, the PLA can maintain persistent air dominance on both sides of the strait, backed by ground-based missile defenses and airborne early warning assets like the KJ-500 AEW&C.

LOOKING BEYOND THE HANGAR

The unveiling marks the beginning of a new operational chapter.

According to defense insiders cited by the South China Morning Post, full-rate production of both variants is expected to commence in 2026, with initial operational capability (IOC) anticipated by 2027–2028.

By that timeline, China would field over 100 stealth aircraft across multiple services, rivaling the early deployment numbers of the U.S. F-35 program.

Future iterations of the J-35 may integrate unmanned loyal wingman drones, AI-driven sensor fusion, and hypersonic weapon compatibility—capabilities that would define the sixth-generation battlespace.

Yet challenges remain formidable.

U.S. export controls on semiconductor components and advanced carbon-fiber composites continue to constrain China’s ability to mass-produce critical avionics.

There are also growing concerns within Western intelligence circles about cyber vulnerabilities in the PLA’s digital network linking stealth platforms to ground command systems.

Nevertheless, the symbolism of the open hangar doors cannot be overstated.

It represents China’s transition from reverse-engineering Western designs to defining its own stealth identity.

In a single video, Beijing has told the world that the age of Chinese opacity in advanced aviation is over.

CONCLUSION

The first public glimpse into the J-35 and J-35A production lines is far more than a visual reveal—it is a calculated strategic gesture in the information domain.

China’s decision to expose its stealth fighter assembly floor reflects growing confidence in its industrial and military sophistication, a confidence that will inevitably ripple across regional defense strategies.

As Xi Jinping continues his drive toward building a “world-class military by 2049,” the J-35 stands as the physical manifestation of that ambition—sleek, shadowed, and increasingly ready for combat.

The hangar doors have opened.
And the dragon’s wings are unmistakably spreading. — DEFENCE SECURITY ASIA
