Tejas Light Combat Aircraft: A Marvel of Indian Engineering

The Tejas Light Combat Aircraft (LCA) is a marvel of Indian engineering. Developed by Hindustan Aeronautics Limited (HAL), Tejas is a single-engine, lightweight, multi-role fighter. It showcases India’s ability to design, develop, and produce advanced military aircraft.

What is the Tejas Light Combat Aircraft?

Tejas is a supersonic, multi-role fighter jet. It was created to replace the aging MiG-21 fighters in the Indian Air Force (IAF). However, in 2021, the Ministry of Defence clarified that Tejas is now part of a broader IAF modernization program.

Key Features:

• Supersonic Speed: Tejas can reach speeds up to Mach 1.8.
• Lightweight: Its composite airframe makes it light and durable.
• Multi-role Capability: It performs air-to-air, air-to-ground, and reconnaissance missions.
• Advanced Avionics: It has state-of-the-art radar and electronic warfare systems.

Development and Evolution

Tejas development began in the 1980s. Despite many challenges, the persistent efforts of Indian engineers led to its success.

Milestones:

• 2001: Tejas made its maiden flight.
• 2016: The first Tejas squadron became operational.
• 2021: HAL started a third production line, increasing production capacity.

Production Variants

Tejas has three main variants: Mark 1, Mark 1A, and the trainer/light attack aircraft. The IAF has ordered 123 Tejas aircraft and plans to procure 97 more.

Indigenous Content:

• Tejas Mark 1: 59.7% by value and 75.5% by the number of line replaceable units.
• Tejas Mark 1A: Expected to surpass 70% indigenous content soon.
