The Zhuhai Airshow presented a remarkable lineup of advanced military technology, prominently featuring the J-35A—a new fifth-generation stealth fighter from China’s Shenyang Aircraft Corporation. This event showcased a range of aircraft, drones, and munitions, highlighting the significant advancements of the People’s Liberation Army (PLA) and PLA Air Force (PLAAF) in modern air combat capabilities.
Among the various hardware displays, the J-35A stood out, drawing immediate comparisons to the American Lockheed Martin F-35 Lightning II, one of the most advanced and widely adopted fighters globally. Both aircraft represent the pinnacle of stealth technology and are designed to meet the rigorous demands of contemporary warfare. Despite their apparent similarities in design and purpose, the J-35A and F-35 embody distinct strategic priorities and technological paths shaped by the unique defense needs of China and the United States.
Background and Strategic Positioning of the J-35A Stealth Fighter
The J-35A, originating from the Shenyang Aircraft Corporation’s FC-31 technology demonstrator, represents a significant evolution in Chinese military aviation technology. Initially conceptualized as a potential export without direct PLA support, the FC-31 underwent substantial modifications to meet the stringent requirements of modern air combat, showcasing its capabilities through various prototypes first flown in 2012 and 2016.
By the mid-to-late 2010s, the design caught the PLA Navy’s (PLAN) attention, which led to its development into a carrier-borne fifth-generation fighter, tentatively named the J-35. The first prototype, flown in October 2021, featured notable enhancements such as an enlarged folding wing, reinforced landing gear, and a catapult launch bar. These modifications, along with an enhanced dorsal fuselage hump and sophisticated sensor array, indicated a mature design aimed at carrier operations.
In the past, the PLA Air Force (PLAAF) showed interest in adapting this advanced platform for land-based operations. By 2023, emerging prototypes with adaptations such as a reduced wingspan pointed to specific modifications tailored to the PLAAF’s operational needs. This version was officially designated as the J-35A during the Zhuhai Airshow 2024, coinciding with the PLAAF’s 75th anniversary.
The J-35A and its variants often draw comparisons to the United States’ F-35, reflecting shared design features typical of medium-sized, fifth-generation fighters, such as dual-side air intakes and similar wing and tail configurations.
Design Comparison of J-35A and F-35 Fighter Jets
Stealth and Airframe Design
Both the J-35A and the F-35 are engineered with an emphasis on low-observable, stealth technology, evident in their sleek and smooth airframes. These designs are crucial for minimizing radar cross-section (RCS) and enhancing operational efficacy by staying undetected during missions. The aircraft feature streamlined surfaces and curvature that disrupt radar wave detection, a fundamental aspect for stealth operations.

Vertical Stabilizers and Canards
The J-35A and F-35 incorporate similar aerodynamic components like canards and vertical stabilizers arranged in a distinctive V-like structure. This setup aids in maintaining a stealth profile and plays a critical role in reducing turbulence, further decreasing radar visibility. Subtle differences in their designs underscore divergent engineering approaches. The J-35A’s stabilizers are slightly wider and set at a different angle, potentially offering better aerodynamic performance tailored to the specific operational requirements of the Chinese military. This could influence the aircraft’s agility and its RCS.
Conversely, the F-35 features more sharply angled stabilizers optimized for an enhanced stealth profile. This design choice reflects a deliberate focus on radar evasion, integral to the F-35’s role in U.S. and allied operations, ensuring superior performance even in challenging conditions.
Cockpit Ergonomics and Visibility
The cockpit design of both aircraft fuses functionality and advanced technology, designed to meet the rigors of modern air combat. Each cockpit has a rounded glass canopy, optimizing pilot visibility and situational awareness—crucial during high-speed, high-stress combat scenarios.
The J-35A’s cockpit is narrower with a simpler design and less curvature in the canopy glass, suggesting a focus on practicality and cost-efficiency. However, this design could slightly elevate the RCS, albeit still adhering to stealth norms. In contrast, the F-35’s cockpit is more expansive, featuring a sophisticated, rounded canopy with extensive glass coverage. Specialized coatings on the F-35’s canopy enhance its stealth capabilities, significantly reducing its radar signature while prioritizing pilot comfort and visibility.
Engine Design and Stealth Optimization
The rear sections of the J-35A and F-35 showcase significant differences in design philosophy, particularly around the engine housings. The J-35A opts for a more enclosed engine design with fewer visible edges and a smoother outline around the exhaust, aimed at minimizing radar reflections—a crucial element in stealth technology. This design is likely optimized to meet the J-35A’s unique performance specifications, possibly prioritizing operational flexibility in varied combat scenarios.
In contrast, the F-35’s exhaust system is more intricate, with defined features that reflect advanced American engineering practices aimed at maximizing stealth. The pronounced design and use of cutting-edge materials in the F-35’s exhaust system illustrate a comprehensive approach to reducing its radar footprint, aligning with the aircraft’s strategic role in achieving air superiority.
Wing Design and Aerodynamic Efficiency
The wing designs of the J-35A and F-35 further reflect their distinct tactical priorities. The J-35A features slightly more angular wings, designed to enhance maneuverability—a critical factor in dogfights and rapid tactical shifts. This design choice supports the J-35A’s presumed role in regional dominance and quick-response scenarios.
The F-35, however, sports smoother, more contoured wings that align with its overarching stealth strategy. These wings are engineered to minimize radar reflections and maintain stability at high speeds, supporting the F-35’s role in deep-strike missions and sustained air operations over hostile territory.
Air Intakes and Landing Gear
The design variations extend to both aircraft’s air intakes and landing gear. The J-35A’s air intakes are wider and more angular, possibly increasing engine airflow and improving performance but at a potential cost to its stealth profile. Meanwhile, the F-35’s air intakes are designed with stealth as a paramount consideration, featuring a rounded, smooth structure that enhances airflow while minimizing radar detection.
The J-35A’s landing gear is simpler and more robust, likely designed to endure diverse and potentially rugged operational environments. On the other hand, the F-35’s landing gear is more complex, incorporating features that reduce radar cross-section and enhance the overall stealth profile, which is critical for operations in highly contested areas.
