Dogfight for Dominance: Why the JF-17 Thunder Is Winning the Global Market Over India’s Tejas
Though both aircraft fall within the same lightweight multirole category, they embody divergent philosophies—the JF-17 as a budget-friendly, export-optimized workhorse supported by Chinese military diplomacy, and Tejas as a symbol of sovereign capability and long-term indigenous innovation.
(DEFENCE SECURITY ASIA) — In the high-stakes theatre of modern aerial warfare, South Asia’s two indigenous light fighters—the Pakistan-China co-developed JF-17 Thunder and India’s domestically built HAL Tejas—have emerged as strategic flagships representing distinct national doctrines, industrial trajectories, and geopolitical alignments.
The JF-17 Thunder, known in Chinese designation as the FC-1 Xiaolong, is the brainchild of strategic collaboration between Pakistan Aeronautical Complex (PAC) and China’s Chengdu Aircraft Corporation (CAC), conceived to replace Pakistan’s aging Mirage and F-7 fleets with a modern, cost-efficient multirole platform.
Designed from the outset for affordability, simplicity, and high sortie rates, the JF-17 has evolved into a potent 4.5-generation combat aircraft, with the latest Block III variant featuring AESA radar, advanced avionics, and access to China’s premier long-range air-to-air missiles.
Conversely, the HAL Tejas, a product of India’s long-gestating Light Combat Aircraft (LCA) program led by Hindustan Aeronautics Limited (HAL) and supported by DRDO, is the centerpiece of New Delhi’s aerospace self-reliance strategy under the “Make in India” framework.
A technological leap for India’s defence industry, Tejas is designed around agility, low radar cross-section, modular architecture, and future scalability—embodied most recently in its enhanced Mk1A variant equipped with Israeli AESA radar, improved EW systems, and expanded multirole capability.
Though both aircraft fall within the same lightweight multirole category, they embody divergent philosophies—the JF-17 as a budget-friendly, export-optimized workhorse supported by Chinese military diplomacy, and Tejas as a symbol of sovereign capability and long-term indigenous innovation.
1. Origin and Strategic Philosophy
The JF-17’s development was driven by Pakistan’s urgent requirement to field an affordable yet modern combat aircraft capable of replacing legacy platforms under budgetary constraints, with China offering a collaborative solution that ensured rapid development, supply-chain resilience, and political support.
Tejas, meanwhile, was born out of India’s post-Kargil realization that aerospace dependence was strategically untenable, aiming to build a high-agility, multi-mission aircraft with minimal foreign reliance—a goal only partially achieved due to key subsystem imports.
2. Airframe and Design
The JF-17 features a conventional mid-mounted delta wing with an all-moving tailplane, incorporating limited composite materials for ease of manufacture and maintainability—sacrificing stealth for simplicity and speed of production.
In contrast, Tejas boasts a tailless delta-wing configuration and utilizes over 45% composite materials, significantly reducing its radar cross-section and structural weight while improving aerodynamic efficiency and survivability.
3. Propulsion Systems
Powered by the Russian RD-93MA turbofan, the JF-17 Block III delivers reliable thrust but suffers from a higher infrared signature and lower thrust-to-weight ratio compared to modern Western engines, although China is advancing the WS-13 as a future indigenous replacement.
Tejas Mk1A uses the U.S.-origin GE F404-GE-IN20, which offers cleaner operation, better reliability, and future scalability—especially with India’s planned transition to the GE F414 engine for the forthcoming Tejas Mk2.
4. Radar and Avionics
The JF-17 Block III is equipped with the Chinese KLJ-7A AESA radar, providing multi-target tracking capabilities, improved resistance to jamming, and compatibility with Chinese long-range missile systems.
Tejas Mk1A is outfitted with the Israeli EL/M-2052 AESA radar, regarded as more mature and capable in real-world performance, coupled with a digital fly-by-wire system, advanced mission computers, and electronic warfare suites co-developed with Israeli and Indian firms—providing a higher degree of situational awareness and digital warfare readiness.
5. Weapons Systems
A major differentiator is the JF-17’s integration of the PL-15 long-range BVR missile, with a reported range exceeding 200 km, giving it a decisive advantage in long-range engagements.
Tejas, while versatile and compatible with the Astra Mk1 (80–110 km) and future Astra Mk2, currently lacks a comparable BVR reach, though its multi-role capabilities are expanding with smart bombs, glide weapons, and upcoming deployment of the BrahMos-NG for precision strike.
6. Cockpit and Interface
The JF-17 offers a digital glass cockpit, HMD, and simplified Chinese avionics, focused on reducing pilot workload and optimizing combat effectiveness through intuitive displays.
Tejas provides a more sophisticated pilot interface with wide-angle HUD, better ergonomics, and fully digital flight control systems that enhance high-agility flight performance and pilot situational awareness.
7. Flight Performance and Agility
With top speeds near Mach 1.6, the JF-17 is adequate for interception and multirole missions, but lacks the high angle-of-attack agility required for modern air dominance roles.
Tejas, by contrast, is highly maneuverable, capable of extreme angles of attack, and optimized for close-in dogfights, aided by its static instability design and advanced flight control systems.
8. Stealth and Survivability
The JF-17’s radar cross-section remains relatively high due to its metallic construction, although the Block III improves survivability with electronic countermeasures and signature management upgrades.
Tejas, built with stealth in mind, has a much lower RCS due to extensive composite use and smoother contours, and is backed by a more comprehensive EW and jamming suite, enhancing battlefield survivability.
9. Cost, Production, and Export Track Record
With a per-unit cost of US$25–32 million, the JF-17 is aggressively priced and already exported to Myanmar, Nigeria, with Iraq and Azerbaijan reportedly in advanced talks, aided by Chinese state financing, political backing, and rapid delivery assurances.
Tejas, priced between US$40–45 million, has attracted significant interest—Argentina, Egypt, and the Philippines among them—but is yet to close its first export deal, hampered by supply chain complexity, foreign component dependencies, and slower procurement cycles.
10. Strategic Relevance
The JF-17 has become the cornerstone of Pakistan’s airpower doctrine, offering high sortie rates, rapid replenishment, and modern BVR capabilities, crucial in the context of persistent tensions with India and limited financial bandwidth.
Tejas, though slower to field and export, is central to India’s long-term aerospace independence, and reflects its ambitions for interoperability with the West, indigenous force structuring, and high-tech military capability development.
Export Verdict: Thunder Roars Louder
Despite India’s aggressive defence diplomacy, it is the JF-17 Thunder that currently dominates the export market, with confirmed deliveries to multiple countries, competitive pricing, and full-spectrum Chinese support making it a highly attractive package for developing air forces.
By comparison, Tejas remains a strategic investment in India’s defence autonomy, but must overcome structural and geopolitical obstacles before it can emerge as a viable export competitor.

So far, JF 17 is winning in every capability on ground. By the time Tejas Mark 1 A and Mk 2 is operational, JF 17 FX will be in the air with clear lead in every field.
The Tejas does not offer sovereign independance at all with its foreign engine, radar and electronic suite. Ejection seat…
It is not a ‘made in India’ plane. Period…
Totally biased narrative for promoting Chinese Defense systems. There was no proof by Pakistani Media of drowning of Indian Fighter Jets. In fact the Chinese HQ9 Air Defense Systems were completely damaged by Indian Air Force. PL15 missiles were easily intercepted by Indias homegrown Akash Defense Air system. Chinese War Planes and Air Defense Systems are just copies of prestigious Fighter Planes and Air Defense Systems of US and Russia. Chinese Fighter Planes. Good for Beggar countries like Pakistan and Bangladesh.
