Tejas Fighter Jet Crash at Dubai Air Show and Defence Indigenisation

Source:The Hindu ↗

Why It Matters

The Tejas LCA is a flagship project for India's self-reliance (Aatmanirbhar Bharat) in defense manufacturing. Incidents involving indigenous platforms have geopolitical and economic implications, testing the reliability of domestic defense products meant for export. The topic directly overlaps with UPSC's focus on defense indigenization and public sector defense enterprises.

Summary

An Indian Air Force (IAF) Tejas fighter jet crashed during a demonstration at the Dubai Air Show, killing Wing Commander Namansh Syal. Hindustan Aeronautics Ltd (HAL), the manufacturer of the indigenous Light Combat Aircraft (LCA), expressed deep sorrow over the incident. The LCA project, initiated in 1984 under the Aeronautical Development Agency (ADA), has been a cornerstone of India's defense indigenization. The Tejas was officially inducted into the IAF's 'Flying Daggers' squadron in 2016. Recent defense procurements include major contracts for the advanced Tejas MK-1A variants, reflecting India's push for self-reliance in aerospace manufacturing.

Key Points

  • A Tejas fighter jet manufactured by HAL crashed during an aerial display at the Dubai Air Show, resulting in the death of IAF pilot Wing Commander Namansh Syal.
  • The Light Combat Aircraft (LCA) project was initiated by the Indian government in 1984, establishing the Aeronautical Development Agency (ADA) to manage the program.
  • The IAF inducted the Tejas in 2016 into the 'Flying Daggers' squadron.
  • India's defense indigenization efforts include a ₹48,000 crore contract signed in 2021 for 83 Tejas MK-1A jets and a 2024 tender for 97 more jets worth over ₹65,000 crore.

Prelims Trap

Tejas Mk-1A is India's first 5th-generation stealth fighter developed entirely by Hindustan Aeronautics Limited (HAL).

Tejas is a 4.5-generation aircraft lacking full structural stealth and supercruise. Additionally, ADA is the design agency; HAL is only the manufacturer.

Static Concepts Connected

Science & Technology: Defence

What distinguishes 5th-generation fighter jets from 4.5-generation aircraft like Tejas?

  • Structural Stealth: 5th-gen fighters have internal weapons bays and radar-absorbent materials to achieve structural stealth. Tejas lacks this comprehensive stealth profile.
  • Supercruise Capability: 5th-gen jets can sustain supersonic flight without using fuel-heavy afterburners. 4.5-gen jets typically cannot.
  • Avionics Bridge: Tejas Mk-1A uses an AESA radar and advanced Electronic Warfare Suite to bridge the gap, placing it firmly in the 4.5-generation tier.
Science & Technology: Aerospace

How does a quadruplex 'Fly-By-Wire' (FBW) system function in modern fighter aircraft?

  • Electronic Interface: Replaces manual flight controls with an electronic interface. Pilot inputs are converted to electrical signals processed by flight control computers.
  • Quadruplex Redundancy: Four independent computer channels operate simultaneously. If one fails, the others override it, ensuring extremely high safety and redundancy for unstable aerodynamic designs.
  • Aerodynamic Stability: Allows structurally unstable aircraft (like delta-wing Tejas) to remain highly maneuverable while computers constantly auto-correct the flight path.

Cross-Topic Patterns

  • LCA Tejas & Jet Engine Dependency

    While Tejas symbolizes domestic aerospace capabilities, its continued reliance on American GE F404/F414 engines highlights a critical gap in India's strategic self-reliance regarding jet engine manufacturing.

  • Defence Exports & Aerospace Diplomacy

    Displaying Tejas at venues like the Dubai Air Show aligns with India's push to become a net security provider and hit its aggressive ₹35,000 crore defence export target by 2025.
