Tejas vs JF-17: Which Light Combat Aircraft is Better?

In the ever-evolving world of military aviation, the Tejas and JF-17 are two formidable contenders vying for supremacy in the skies. Designed and developed by India and Pakistan, respectively, these fighter jets represent the pinnacle of indigenous aerospace engineering. In this comprehensive comparison, we delve into the intricacies of the Tejas and JF-17, assessing their capabilities, strengths, and weaknesses to determine which aircraft holds the upper hand.

Tejas vs JF-17: Which Light Combat Aircraft is Better?

Tejas vs JF 17: The Tejas and JF-17 are both single-engine, multirole combat aircraft. They are designed to be lightweight and agile, and they can be used for a variety of missions, including air-to-air combat, air-to-ground attack, and reconnaissance.

The Tejas is a fully indigenous aircraft that was developed by Hindustan Aeronautics Limited (HAL) in India. It is powered by a General Electric F404-GE-IN20 engine and has a top speed of Mach 1.6. The Tejas is equipped with a variety of weapons and sensors, including the Astra air-to-air missile, the Derby air-to-ground missile, and the Litening targeting pod.

The JF-17 is a jointly developed aircraft by Pakistan Aeronautical Complex (PAC) and the Chengdu Aircraft Corporation (CAC) of China. It is powered by a Klimov RD-93 engine and has a top speed of Mach 1.6. The JF-17 is equipped with a variety of weapons and sensors, including the PL-12 air-to-air missile, the CM-400AKG air-to-ground missile, and the FLIR targeting pod.

Design and Development

The Tejas, also known as the LCA (Light Combat Aircraft), is the result of decades of research and development by India’s HAL (Hindustan Aeronautics Limited). Designed as a lightweight, multi-role fighter, the Tejas features cutting-edge composite materials in its construction, ensuring both strength and agility. Its advanced fly-by-wire control system and a delta wing design contribute to its exceptional maneuverability.

On the other hand, the JF-17 Thunder is a collaborative effort between Pakistan and China’s aviation industries. It was developed to cater to the needs of modern air forces, providing a cost-effective solution with a range of capabilities. The JF-17 boasts a sleek and aerodynamic design, making it a formidable presence in the skies.


When it comes to performance, both aircraft have their unique strengths. The Tejas is equipped with the General Electric F404 engine, delivering impressive thrust-to-weight ratio and superior agility. Its maximum speed surpasses Mach 1.8, allowing for rapid response and interception.

The JF-17, powered by a Chinese-designed RD-93 engine, also offers remarkable performance. With a maximum speed of Mach 1.6, it may not match the Tejas in top speed, but it compensates with a longer operational range, making it suitable for various mission profiles.

Avionics and Armament

Both the Tejas and JF-17 are equipped with state-of-the-art avionics and weapon systems. The Tejas features a modern glass cockpit with a wide array of sensors and avionics, including an advanced radar system. It is capable of carrying an assortment of air-to-air and air-to-ground munitions, making it a versatile platform.

The JF-17 boasts a similar suite of avionics, with a Chinese radar system and compatibility with various missile types. Its ability to carry a diverse range of weaponry makes it adaptable to a wide array of missions, from air superiority to ground attack.

Cost and Export Potential

One of the key factors in evaluating these fighter jets is their cost-effectiveness and export potential. The Tejas, although a highly capable aircraft, has faced challenges in terms of export due to its relatively higher cost compared to some competitors. India has sought to address this by offering upgraded variants and technology transfer agreements.

The JF-17, on the other hand, has gained traction in the international market due to its affordability and competitive capabilities. Pakistan, along with China, has successfully marketed the JF-17 to several countries, expanding its global presence.

Tejas and JF-17 Specifications comparison

Here is a table comparing the specifications of the Tejas and JF-17:

Length13.2 m16.9 m
Wingspan8.2 m9.4 m
Height4.5 m4.8 m
Empty weight6,500 kg7,500 kg
Maximum takeoff weight13,000 kg12,800 kg
Top speedMach 1.6Mach 1.6
Range3,000 km2,500 km
Service ceiling15,000 m15,240 m

In terms of capabilities, the Tejas has a slight edge over the JF-17. It has a higher top speed, a longer range, and a higher service ceiling. The Tejas is also equipped with more modern weapons and sensors.

However, the JF-17 is cheaper to produce and operate. It is also more widely available, as it has been exported to several countries, including Myanmar, and Nigeria.

Ultimately, the choice of which aircraft is better depends on the specific needs of the air force. If the air force is looking for an aircraft with the latest capabilities, then the Tejas is the better choice. However, if the air force is looking for an aircraft that is affordable and widely available, then the JF-17 is the better choice.


The Tejas and JF-17 are two capable light combat aircraft. They are both suitable for a variety of missions, and they offer a good balance of performance and cost. The choice of which aircraft is better depends on the specific needs of the air force.
