• Cockpit: Glass cockpit with multifunction displays, hands-on throttle and stick (HOTAS) controls.

• Weapons: Capable of carrying a variety of weapons including:

  • Air-to-air missiles (AIM-120 AMRAAM, Astra)

  • Precision-guided bombs

  • Anti-ship missiles

  • 23mm GSh-23 cannon

• Electronic Warfare: Advanced self-protection suite including radar warning receivers and chaff/flare dispensers.

This multi-role capability enhances the versatility and combat readiness of the aircraft.

2.3 Engine and Performance

The Tejas employs a single General Electric F404-GE-IN20 turbofan engine, delivering robust thrust for supersonic speeds.

This combination allows the Tejas to perform quick strikes, air patrols, and engage in dogfights with enemy jets.

3. Operational Role and Deployment

3.1 Indian Air Force Integration

The Tejas has been inducted into various IAF squadrons, gradually replacing older MiG-21s and Jaguar aircraft. Its deployment enhances India’s air combat capabilities, especially in the context of regional threats.
