IAF Commemorates 25th Anniversary of Tejas Light Combat Aircraft’s First Flight

On January 4, 2026, the Indian Air Force (IAF) proudly commemorated the 25th anniversary of the maiden flight of the indigenously developed Tejas Light Combat Aircraft (LCA). This milestone marks a defining moment in India’s journey towards self-reliance in defence aviation under the broader vision of Atmanirbhar Bharat.

The Tejas programme stands as a testament to India’s growing technological capability in designing, developing, and manufacturing modern combat aircraft.

Genesis of the Tejas LCA Programme

The Tejas LCA programme was launched in 1983 by the Government of India with a clear strategic objective—to replace the ageing and obsolete fighter aircraft fleet of the Indian Air Force with a modern, lightweight, multi-role combat aircraft designed and built in India.

This ambitious initiative laid the foundation for India’s indigenous aerospace ecosystem, involving multiple research institutions, public sector undertakings, and private industry partners.

Historic Maiden Flight: 4 January 2001

The defining breakthrough came on 4 January 2001, when the Technology Demonstrator-1 (TD-1) aircraft successfully took to the skies.

• Pilot: Wing Commander Rajiv Kothiyal
• Take-off Location: Hindustan Aeronautics Limited (HAL) Airport
• City: Bengaluru, Karnataka

This successful flight marked India’s entry into the elite group of nations capable of designing and flying indigenous supersonic combat aircraft.

From Test Flight to IAF Induction

The maiden flight initiated an extensive flight testing and evaluation phase, leading to:

• Operational clearance
• Gradual induction into IAF squadrons
• Continuous upgrades based on operational feedback

Over the years, Tejas evolved from an experimental platform into a frontline fighter aircraft, significantly enhancing the IAF’s combat readiness.

Advanced Variants: Tejas Mk-1A

Building on operational experience, India developed Tejas Mk-1A, featuring:

• Improved avionics
• Enhanced radar and electronic warfare systems
• Better maintainability and operational availability

Major Defence Deal (2025)

In late 2025, HAL secured a landmark order for 97 additional Tejas Mk-1A aircraft, valued at over ₹62,370 crore, making it one of the largest indigenous fighter aircraft contracts in India’s defence history.

Role of Private Industry: VEM Technologies

India’s growing defence-industrial partnership was highlighted in 2025:

• May 2025: VEM Technologies delivered the first centre fuselage assembly for Tejas Mk-1A to HAL in Hyderabad, Telangana
• September 2025: The second centre fuselage assembly was handed over

This collaboration underscores the expanding role of the private sector in defence manufacturing.

Why Tejas Matters for India

• Reduces dependence on foreign fighter jets
• Strengthens domestic aerospace manufacturing
• Enhances IAF operational capability
• Generates high-skilled employment
• Supports export potential of Indian defence platforms
