Why in News? 

• The Chief of Defence Staff (CDS) has highlighted the urgent need for a comprehensive Counter-Unmanned Aerial System (C-UAS) to tackle the rising threat of unmanned aerial systems (UAS) in modern warfare. 
• The increasing use of drones in military and terrorist activities necessitates advanced detection, tracking, and neutralization systems. 

What is a Counter-Unmanned Aerial System (C-UAS)? 

• A C-UAS is a specialized system designed to detect, track, and neutralize drones and other UAS, ensuring security and defence readiness. 

 India’s Efforts to Strengthen C-UAS Capabilities 

• Drone Detect, Deter, and Destroy (D4S) System: 
  • Developed by the Defence Research and Development Organisation (DRDO). 
  • Detects and jams micro drones within a range of 3 km. 
  • Uses lasers to neutralize targets up to 1 – 2.5 km away. 
• Drone Guard System: 
  • Developed by Bharat Electronics Limited (BEL). 
  • Designed to detect, track, and neutralize unauthorized drones in sensitive areas. 
• Pilotless Target Aircraft – LAKSHYA: 
  • A high-subsonic reusable aerial target system. 
  • Powered by a gas turbine engine and can be launched from land or ships. 

 Significance of Strengthening C-UAS Systems 

• Enhances national security by preventing drone-based attacks on critical defence installations. 
• Aids in counterterrorism operations by detecting and neutralizing rogue drones. 
• Strengthens India’s preparedness in modern warfare and asymmetric threats.
