Mains Practice Questions

Introduction:

The proliferation of Unmanned Aerial Vehicles (UAVs), or drones, by non-state actors has introduced a "third dimension" to India’s security challenges. The misuse of low-cost, commercial-off-the-shelf (COTS) drones for smuggling, surveillance, and "kamikaze" attacks has moved from a peripheral concern to a primary threat to Border Management and Internal Security.

Body

Challenges to Border Management

• Asymmetric Smuggling (Narcotics & Arms): Non-state actors along the Western Border (Punjab/J&K) use drones to drop high-value, low-volume payloads like heroin, synthetic drugs, and small arms.
  • In the past five years, 4,000+ drone sightings were reported, including 967 incursions that were intercepted or neutralised, leading to the seizure of ammunition, weapons, and drugs.
• Terrain Neutralization: Drones bypass traditional physical barriers like the Comprehensive Integrated Border Management System (CIBMS) and smart fencing. They navigate riverine gaps, dense forests, and mountainous stretches (e.g., the India-Myanmar border) where human patrolling is limited.
• Surveillance & Intelligence Gathering: Terrorist groups use mini-UAVs for real-time reconnaissance of Border Outposts (BOPs) and troop movements, eroding the element of strategic secrecy for Indian security forces.
• Saturation/Swarm Tactics: The threat of "drone swarms" aims to overwhelm traditional air defense radars, which are often tuned for larger aircraft and find it difficult to track "Low, Slow, and Small" (LSS) targets.

Internal Security Threats

• Vulnerability of Critical Infrastructure: Drones pose a direct threat to "soft" and "hard" targets, including oil refineries, nuclear plants, and airports.
  • India is deploying anti-drone systems across civilian airports following rising global incidents of airport disruptions.
• Assassination & Urban Terror: The 2021 Jammu Air Force Station attack was a harbinger of drone-led "kinetic strikes."
  • Small drones can be rigged with IEDs for targeted assassinations or to incite panic in crowded public spaces and political rallies.
• Cyber-Physical Breach: Drones can be used to park near secure facilities to sniff Wi-Fi signals or intercept unencrypted communication, bridging the gap between physical and cyber warfare.

India’s Institutional Preparedness: Assessment

• Preparedness
  • Induction of D4 System: The DRDO-developed "Drone Detect, Deter, and Destroy" (D4) system was formally inducted into India’s armed forces.
    • Also, India has developed, Bhargavastra, designed to neutralise enemy drones, especially those operating in swarms.
  • Indigenous Solutions: Private players like Zen Technologies and VEM Technologies (Slingshot system) have developed layered anti-drone architectures.
    • The Indrajaal autonomous drone dome also provides wide-area protection against swarms.
  • Project Sudarshan Chakra: Announced in 2025, this futuristic mission aims to create a comprehensive national security shield by 2035, integrating AI-driven predictive technologies to intercept threats before they enter Indian airspace.
  • Standard Operating Procedures (SOPs): The Ministry of Home Affairs (MHA) have issued comprehensive guidelines to state police forces on handling rogue drones.
• Gaps and Adequacy Assessment
  • The "Cost-Exchange" Ratio: While a drone costs a few thousand rupees, an interceptor missile costs lakhs. India needs more Directed Energy Weapons (DEWs) and high-powered lasers to make the defense economically sustainable.
  • Component Dependency: Despite the "Atmanirbhar" push, critical sensors and high-density batteries are still largely imported, creating a vulnerability in the "Secure-by-Design" architecture.
  • Legal "Grey Zones": Current laws are still evolving regarding the "Right to Shoot Down" drones over private property or in urban areas where falling debris could cause collateral damage.

Conclusion

India’s preparedness against drone threats has matured significantly following events like Operation Sindoor (2025). The move toward AI-integrated, layered defense systems and a "Secure-by-Design" procurement policy shows a high level of institutional awareness. However, the speed of innovation among non-state actors, who use "disposable technology", requires India to maintain a cycle of continuous technological evolution and foster a deeper public-private partnership in electronic warfare.
