• 😀 Tejas is equipped with advanced avionics including the Israeli EL/M-2052 AESA radar and modern electronic warfare systems, giving it an edge over the JF-17.
• 😀 The Tejas has a higher weapons payload capacity (5300 kg) and better integration of air-to-air and air-to-ground missiles, including advanced systems like the Brahmos missile.

Q & A

What is the HAL Tejas, and what role does it play in India's defense capabilities?

The HAL Tejas is an Indian light combat aircraft developed by Hindustan Aeronautics Limited with design input from the Aeronautical Development Agency and technical support from the Defence Research and Development Organisation. It was developed under India's Light Combat Aircraft program to enhance indigenous aerospace capabilities. Tejas made its first flight in 2001 and entered service with the Indian Air Force (IAF) in 2015.

What are the main differences between the design philosophies of the HAL Tejas and the JF-17 Thunder?

The Tejas features a tailless delta-wing design optimized for agility, aerodynamic efficiency, and stealth, while the JF-17 uses a conventional design with mid-mounted wings and a tailplane. The Tejas incorporates 45% composite materials, making it lighter and stealthier, whereas the JF-17 relies more on metal alloys, which makes it heavier and less stealthy.

What engine powers the HAL Tejas, and how does it compare to the engine used in the JF-17?

The HAL Tejas Mk1 is powered by the American-made General Electric F404-GE-IN20 turbofan engine, which is known for its reliability and high thrust-to-weight ratio. The upcoming Mk2 version will use the more powerful GE F414 engine. In contrast, the JF-17 uses the Russian RD-93 engine, which provides less thrust and is known to produce more smoke, making the aircraft more visible.

How do the performance characteristics of the Tejas and JF-17 compare?

The Tejas can reach speeds up to Mach 1.8 (2,200 km/h) with a service ceiling of 52,500 feet, while the JF-17 has a lower top speed of Mach 1.6 (1,975 km/h) but a higher service ceiling of 55,000 feet. The Tejas has a combat radius of around 740 km, whereas the JF-17 has a slightly longer combat radius of about 900 km but shorter endurance overall.

What types of radar and sensors are integrated into the Tejas and JF-17?

The Tejas Mk1A features advanced avionics, including a digital glass cockpit and the Israeli EL/M-2052 or indigenous Uttam AESA radar, which provides superior target detection and resistance to jamming. The JF-17 Block III upgrades to the Chinese KLJ-7A AESA radar and adds a helmet-mounted display, but the Tejas still benefits from more advanced and integrated sensor technologies.

How do the weapons capabilities of the Tejas and JF-17 differ?

The Tejas Mk1A can carry a wide range of advanced weapons, including Astra and Derby air-to-air missiles and precision-guided air-to-ground munitions like GPS-guided bombs and Paveway series missiles. It has a maximum weapons payload of 5,300 kg. The JF-17, while versatile, can carry similar weapons like PL-5E and PL-12 missiles but has a smaller payload capacity of 3,400 kg.

How does the stealth and survivability of the Tejas compare to the JF-17?

The Tejas incorporates several stealth features, such as a reduced radar cross-section (RCS) and radar-absorbing materials, making it more survivable in contested environments. It also has a modern electronic warfare suite for self-protection. The JF-17 has limited stealth features and relies more on low-observable design, but it lacks the advanced stealth materials and electronic warfare systems found in the Tejas.

What role does the JF-17 play in Pakistan's defense strategy?

The JF-17 Thunder was developed as a cost-effective replacement for older combat aircraft like the Mirage III, Mirage 5, and the F-7P/PG in the Pakistan Air Force. It serves as a versatile platform for both air-to-air and air-to-ground roles and is designed to be cheaper and easier to produce and maintain compared to other advanced aircraft.

What is the expected impact of the Tejas Mk2 on the Indian Air Force's capabilities?

The Tejas Mk2, with its upgraded GE F414 engine, will offer enhanced performance in terms of speed, altitude, and payload capacity, further strengthening India's air combat capabilities. The Mk2 version is expected to maintain the advanced avionics and stealth features of the Mk1, making it even more capable for high-performance missions.

How does the number of aircraft in service affect the military capabilities of India and Pakistan?

While India has a smaller number of Tejas aircraft in service (38 Mk1 and 83 Mk1A on order), the Tejas offers superior technology and combat potential. On the other hand, Pakistan has a numerical advantage with over 175 JF-17s in service, giving it more aircraft for regional defense, but the JF-17 lacks the advanced technology and capabilities that Tejas offers.
