As global power dynamics shift, China's latest stealth fighter, the J-35, is drawing international attention. With the U.S. F-35 already dominating the skies, can China’s new jet challenge American air superiority? Here's a comprehensive 1000-word comparison that breaks down every critical aspect of these two fifth-generation fighters.
1. Stealth Design and Radar Signature
F-35 Lightning II: The F-35 is a cornerstone of the U.S. military's stealth strategy. Designed with advanced radar-absorbent materials and a sleek, low-profile airframe, it boasts an exceptionally low radar cross-section (RCS). Official figures aren't public, but experts estimate its RCS to be as low as 0.001 m².
J-35 Gyrfalcon (Naval FC-31 Variant): China’s J-35 borrows heavily from the stealth design principles of its Western counterparts. It features internal weapon bays, angled surfaces, and a smaller vertical radar profile. However, the twin-engine configuration likely increases its RCS, putting it slightly behind the F-35 in pure stealth performance.
Verdict: The F-35 remains the benchmark for stealth. The J-35 is a significant leap for China, but still a step behind the U.S. in radar evasion.
2. Engine Performance and Infrared Signature
F-35: Powered by a single Pratt & Whitney F135 engine, the F-35 achieves superior thrust and excellent heat management. Its design minimizes its infrared signature, making it harder for heat-seeking missiles to lock on.
J-35: Currently flying with RD-93 engines from Russia, the J-35 is expected to eventually adopt the domestically produced WS-19 engines. The twin-engine setup may provide better redundancy and thrust but comes at the cost of increased heat output.
Verdict: The F-35 has the edge in both efficiency and IR stealth, thanks to its advanced engine design.
3. Avionics, Sensors, and Data Fusion
F-35: The F-35 is a flying sensor suite. It includes the AN/APG-81 AESA radar, the Distributed Aperture System (DAS), and the Electro-Optical Targeting System (EOTS). These sensors, combined with powerful data fusion capabilities, allow the F-35 to track multiple targets, share data across platforms, and react in real-time.
J-35: China's J-35 is expected to feature the KLJ-7A AESA radar and the EOTS-86 targeting system. While these are modern and capable, the J-35's data fusion capabilities remain less tested in actual combat environments.
Verdict: F-35's battlefield awareness and real-time information sharing are unmatched. The J-35 is catching up but needs proven performance.
4. Weapons Payload and Mission Flexibility
F-35: With a maximum internal and external payload of 18,000 lbs, the F-35 can carry an array of guided missiles, bombs, and electronic warfare equipment. Its three variants (F-35A, B, and C) allow for flexible deployment across air forces, navy carriers, and short-takeoff environments.
J-35: The J-35 is estimated to have a payload capacity of 16,000 lbs. It will likely carry PL-10 and PL-15 air-to-air missiles, precision-guided bombs, and other Chinese-developed munitions. The focus is on internal weapon storage to preserve stealth.
Verdict: While both jets carry similar payloads, the F-35's proven combat versatility and multi-variant options provide greater mission adaptability.
5. Production and Deployment Status
F-35: The F-35 program is in full swing. Over 900 units have been delivered to more than 15 countries. It has logged thousands of flight hours and has already seen combat.
J-35: Still in the prototype phase, the J-35 is undergoing testing with the People's Liberation Army Navy (PLAN). It completed its first land-based flight in 2023 and is being refined for carrier-based operations.
Verdict: The F-35 is combat-tested and globally deployed. The J-35 is promising but still years away from full operational status.
6. Carrier Compatibility and Naval Strategy
F-35C (Carrier Variant): Designed for U.S. Navy supercarriers, the F-35C features larger wings and reinforced landing gear. It works seamlessly with catapult-assisted launches and arrestor gear systems.
J-35: Built to operate from China’s upcoming catapult-equipped aircraft carriers, the J-35 aims to give the PLAN a credible carrier-based stealth option. However, the integration of such jets into full naval operations is still in progress.
Verdict: The F-35C has already demonstrated its capabilities in real carrier operations, while the J-35 is still preparing to enter the stage.
7. Strategic Implications and Global Reach
F-35: The F-35 serves as a force multiplier. Its global adoption allows for unparalleled interoperability between U.S. allies. Its presence in Europe, Asia, and the Middle East adds strategic depth to the U.S.'s global footprint.
J-35: China sees the J-35 as a critical asset for expanding its influence in the South China Sea and Indo-Pacific. It also positions the J-35 as an alternative to Western jets for countries reluctant to align with the U.S.
Verdict: The F-35 plays a larger role in shaping global air power. The J-35 reflects China’s ambition but lacks global reach at this point.
8. Technological Maturity and Ecosystem Support
F-35: Years of investment have built a strong support network for maintenance, training, and upgrades. Lockheed Martin continues to evolve the aircraft with software updates and performance enhancements.
J-35: While impressive in design, the J-35 lacks a comparable support ecosystem. Training, sustainment infrastructure, and software development are still developing.
Verdict: F-35 has the backing of a mature ecosystem. The J-35 is still building its
foundation.
Conclusion: An Inevitable Rivalry, But Not Yet Equals
The J-35 is a bold statement of China’s aerospace progress and a clear signal of its military intentions. It showcases rapid development and impressive engineering, indicating that China is closing the gap in stealth fighter technology.
However, the F-35 remains in a class of its own for now. With unmatched combat readiness, superior sensor integration, and extensive global deployment, it sets the standard for fifth-generation fighters.
