Tejas Mk2 vs J-35 Fighter Jet: The 2025 Face-Off Between India and China’s Airpower
 |
| Tejas MK -2 Vs J35 |
In the dynamic world of modern military aviation, two powerful nations — India and China — are steadily preparing for future conflicts, not just with numbers, but with next-generation fighter jets. As of 2025, two names stand out in this regional power play: India’s Tejas Mk2 and China’s J-35 (also known as FC-31 Gyrfalcon).
Both aircraft represent their countries’ ambitions, technological evolution, and military aspirations. But how do they compare? Which one will truly dominate the skies of South Asia and the Indo-Pacific?
Tejas Mk2: India’s Indigenous Leap Forward
India's Tejas Mk2 is an upgraded successor to the existing Tejas Mk1A, developed by HAL (Hindustan Aeronautics Limited). Designed to replace the aging Mirage 2000 and MiG-29s, the Mk2 is a 4.5+ generation fighter meant to fill a critical gap in the Indian Air Force (IAF).

- Stealth Features: Partial RCS reduction using composites
- Avionics: Fly-by-wire system, advanced digital cockpit
The Tejas Mk2 is built for maneuverability, reliability, and versatility. It is tailored to Indian defense needs across different terrains — mountains, deserts, and oceans.
J-35 (FC-31): China’s Stealth Contender
The J-35, also known as FC-31 or Gyrfalcon, is China's fifth-generation stealth fighter, being developed by Shenyang Aircraft Corporation. In 2025, it is expected to begin naval deployment and possible exports.
Key Features of J-35:
- Engine: WS-19, twin-engine configuration
- Speed: Estimated Mach 1.8+
- Range: Around 2,000 km
- Payload: Around 8 tons
- Radar: Chinese AESA (classified specs)
- Stealth: Full stealth profile with internal weapons bays
- Sensors: IRST, advanced targeting and tracking
The J-35 is designed for carrier operations and power projection beyond mainland China. It is part of China’s long-term goal to challenge US and allied air dominance in the Pacific.

Strategic Comparison: Context Matters
While the J-35 appears more advanced in stealth and range, the real test lies in deployment and mission adaptability. The Tejas Mk2 is designed with India's terrain and strategic concerns in mind. It will serve in the IAF as a versatile multirole jet with low maintenance costs and high maneuverability.
China’s J-35, though technologically impressive, lacks real combat testing and remains in limited production. It will serve mainly from aircraft carriers in the coming years, and its success depends on China's ability to integrate it with naval fleets.
Q&A: Common Questions About the Tejas Mk2 and J-35
Q: Is the J-35 a combat-proven aircraft?
No. As of 2025, the J-35 has not seen real combat and is still undergoing trials.
Q: When will Tejas Mk2 be inducted into the Indian Air Force?
Full-scale production and initial induction are expected between 2026 and 2028.
Q: Which aircraft has better stealth capabilities?
The J-35 has better stealth due to its internal weapons bays and design. Tejas Mk2 has limited stealth features through composite materials and reduced radar signature.
Q: Can Tejas Mk2 match the J-35 in air-to-air combat?
While the J-35 may have stealth and range advantages, the Tejas Mk2 could still be effective in close air combat and short-range missions due to superior agility and modern avionics.
Looking Ahead
Both Tejas Mk2 and J-35 represent major milestones in their countries' military aviation programs. India is steadily building a reliable, self-made air fleet, while China is pushing for dominance through fifth-generation designs and naval integration.
In future scenarios, air combat won’t just depend on stealth or speed. Factors like logistics, training, battlefield conditions, and electronic warfare will decide who controls the skies.
The 2025 face-off is just the beginning. What happens next depends on how well each nation can turn these machines into war-winning tools.
