In the high-stakes theatre of modern aerial warfare, two indigenous light fighters have emerged as flagships of strategic ambition and technological aspiration: the Pakistan-China co-developed JF-17 Thunder and India’s HAL Tejas. While both aircraft belong to the same lightweight multirole category, they are products of starkly different national doctrines, industrial approaches, and geopolitical alignments. This is not merely a contest of machines, but a reflection of how two rival nations approach defence sovereignty, industrial policy, and strategic partnerships.
The JF-17 Thunder (Chinese designation: FC-1 Xiaolong) is a product of necessity. Pakistan needed a cost-effective, modern replacement for its aging Mirage and F-7 fleets. China’s Chengdu Aircraft Corporation (CAC) and the Pakistan Aeronautical Complex (PAC) joined forces to fast-track development. The result was a platform built for affordability, ease of maintenance, and rapid deployment.
India’s HAL Tejas emerged from a different motivation—autonomy. Following the Kargil conflict, New Delhi recognized the strategic liability of relying on foreign suppliers for air power. The Light Combat Aircraft (LCA) program, led by Hindustan Aeronautics Limited (HAL) and supported by DRDO, aimed to create a high-agility, multirole fighter that could anchor India’s aerospace self-reliance.
The JF-17’s design prioritizes functionality over flair. Featuring a mid-mounted delta wing, all-moving tailplane, and largely metallic structure, it is engineered for mass production and rugged performance. Composite materials are used sparingly, favoring ease of repair and lower manufacturing costs.
Tejas, in contrast, boasts a tailless delta-wing layout with over 45% composite content. This significantly reduces its radar cross-section, enhances structural strength, and contributes to aerodynamic efficiency. It is a precision-crafted airframe designed for survivability and high performance.
The JF-17 is powered by the Russian RD-93MA turbofan, offering sufficient thrust but falling short on fuel efficiency and thermal signature management. Efforts are underway in China to replace it with the WS-13 engine, but challenges remain.
Tejas uses the GE F404-GE-IN20 engine, a proven powerplant known for reliability, efficiency, and lower IR signature. India plans to transition to the more powerful GE F414 for the Tejas Mk2, opening doors to improved speed, thrust, and payload capacity.
The latest JF-17 Block III features the Chinese KLJ-7A AESA radar, offering decent multi-target tracking, electronic warfare resistance, and integration with China’s advanced PL-15 BVR missile. The PL-15’s range of over 200 km is a strategic game-changer.
Tejas Mk1A is equipped with the Israeli EL/M-2052 AESA radar, generally considered superior in real-world performance. Its digital flight control systems, Indian-Israeli EW suites, and advanced mission computers make Tejas more digitally integrated and situationally aware.
Pakistan’s JF-17 packs a punch with the PL-15 missile, giving it a decisive edge in long-range engagements. The aircraft also carries Chinese-origin smart bombs, guided munitions, and anti-ship missiles.
Tejas has yet to field a missile of PL-15’s class but is compatible with the Astra Mk1 (80–110 km) and the upcoming Astra Mk2. Additionally, the Tejas platform is being readied to integrate the BrahMos-NG, providing a formidable strike option.
The JF-17’s cockpit includes a digital glass interface and a Chinese HMD (Helmet Mounted Display), focusing on reducing pilot workload.
Tejas delivers a more ergonomic and intuitive interface with a wide-angle HUD, better pilot layout, and superior fly-by-wire control systems that enable high-agility maneuvers and better feedback loops during dynamic combat scenarios.
With a top speed near Mach 1.6, the JF-17 serves well in interception and strike roles. However, its agility in close combat is limited by its aerodynamic design.
Tejas is optimized for high-agility flight. Its unstable design, combined with digital flight control, allows it to perform at high angles of attack and engage in superior dogfighting scenarios.
The JF-17’s radar cross-section is relatively high due to its metallic structure, though the Block III variant includes electronic countermeasures and limited RCS reduction.
Tejas, with its stealth-oriented contours and high composite use, has a lower radar signature. Its advanced jamming systems and electronic warfare capabilities further bolster its survivability in contested airspace.
The JF-17’s unit cost of $25–32 million makes it a budget-friendly fighter for developing countries. Pakistan has already exported it to Myanmar and Nigeria, with Iraq and Azerbaijan reportedly next in line. The aircraft’s attractiveness is amplified by Chinese state financing and fast delivery timelines.
Tejas is priced at $40–45 million, reflecting its advanced systems and higher production costs. Though interest has come from Argentina, Egypt, and the Philippines, no export contracts have been finalized. Challenges include a complex supply chain, reliance on foreign subsystems, and slower production cycles.
For Pakistan, the JF-17 is more than a jet; it’s the backbone of its air defence. High sortie rates, rapid replenishment, and long-range missiles make it indispensable. It embodies Pakistan’s pragmatic defence strategy in a constrained fiscal environment.
Tejas, though slower in deployment, is a cornerstone of India’s broader goal of strategic autonomy. It represents the country’s bid for high-tech self-reliance, Western alignment, and future readiness. Its real value lies not just in operational deployment but in the maturation of India’s aerospace ecosystem.

The battle between the JF-17 Thunder and HAL Tejas is not just an arms race; it’s a clash of ideologies. Pakistan’s solution is cost-effective, export-friendly, and operationally sound—a tactical answer to strategic problems. India’s Tejas is a technological bet on self-reliance, high-end warfare, and global alignment.
In the skies of South Asia and beyond, these aircraft are more than machines; they are messengers of national policy, intent, and ambition. Whether Thunder or Tejas ultimately commands the skies may depend as much on politics and procurement as on dogfights and radar locks. The real duel, it seems, is for the future of airpower in the Global South.
