Q6. What are directed energy weapons (DEWs)? Explain their working mechanism. Assess their role in enhancing India’s air defence capabilities. (10 M)

Difficulty Level: Medium

Reference: TH

Why the question:
The Defence Research and Development Organisation (DRDO) announced the successful trial of a Mk-II(A) Laser- Directed Energy Weapon (DEW) system “mastering the technology of disabling missiles, drones and smaller projectiles.

Key demand of the question:
The question demands understanding the concept and functioning of DEWs, and evaluating how they contribute to India’s air defence effectiveness, especially in countering modern aerial threats.

Structure of the Answer:

Introduction
Briefly define DEWs as emerging non-kinetic weapons using focused energy, and mention India’s recent progress.

Body

  • What are DEWs: Define DEWs and mention their types like laser, microwave weapons.
  • Working mechanism: Explain how detection, targeting, and energy emission disable the target.
  • Role in India’s air defence: Highlight their use against drones, missiles, swarms, and cost-effectiveness.

Conclusion
Conclude by stating DEWs as a futuristic force multiplier, and suggest the need for rapid deployment and integration in India’s defence strategy.
