Introduction: Evolving Aerial Threats and India’s Defence Imperative
Since 2021, India has witnessed a sharp rise in drone incursions along its borders, particularly the India-Pakistan frontier, where drone-related incidents increased by 30% between 2021 and 2023 (Border Security Force data, 2023). Over 50% of recent skirmishes involved drone surveillance or attacks, underscoring the asymmetric aerial threat that challenges traditional air defence systems (Indian Express, 2024). The Defence Research and Development Organisation (DRDO) and Indian Air Force (IAF) have responded with indigenous counter-drone solutions like the ‘Droni’ system, which successfully neutralized multiple drone targets during trials (DRDO, 2023). This evolving threat landscape demands a comprehensive overhaul of India’s air defence doctrine, integrating advanced counter-drone technologies and multi-layered defence architectures to maintain strategic and tactical superiority.

Legal and Regulatory Framework Governing Air Defence and Drones
India’s air defence and counter-drone operations operate under multiple legal instruments. The Defence of India Act, 1962 empowers the government to regulate defence-related activities during emergencies. The Arms Act, 1959 (Sections 3 and 25) controls weapon possession and usage, which extends to drone-carried armaments. Cyber offences related to drone misuse fall under the Information Technology Act, 2000 (Sections 66A and 66F), addressing hacking and cyberterrorism. The Ministry of Defence (MoD) issues guidelines on Unmanned Aerial Vehicles (UAV) usage, while the Directorate General of Civil Aviation (DGCA) regulates drone operations under the Drone Rules, 2021, creating a dual regulatory environment that complicates rapid operational deployment in conflict scenarios.
- Defence of India Act, 1962: Emergency powers for defence regulation.
- Arms Act, 1959: Controls weapon possession, relevant to armed drones.
- Information Technology Act, 2000: Addresses cyber offences linked to drone misuse.
- DGCA Drone Rules, 2021: Civil drone regulation, airspace management.
- MoD UAV Guidelines: Military drone deployment and air defence coordination.
Economic Dimensions: Budget and Indigenous Capability
India’s defence budget for 2023-24 is approximately ₹5.94 lakh crore (~$80 billion), with a rising allocation for modernisation that includes air defence and counter-drone technologies (MoD Annual Report, 2023). The global counter-drone market is projected to grow at a CAGR of 15.9%, reaching $4.6 billion by 2027 (MarketsandMarkets, 2023). India’s indigenous drone manufacturing sector is expanding at 20% annually, supported by the ‘Make in India’ initiative and the Defence Acquisition Procedure (DAP) 2023 incentives. The Defence Innovation Organisation (DIO) has accelerated development by fast-tracking 15 start-ups focused on AI-enabled drone detection and neutralisation (DIO Annual Report, 2023).
- ₹5.94 lakh crore defence budget (2023-24), increased focus on air defence.
- Global counter-drone market: $2.5 billion (2022) to $4.6 billion (2027).
- Indigenous drone manufacturing growing 20% annually.
- DIO supports start-ups developing AI-based counter-drone tech.
- Procurement plan includes 10 new long-range SAM systems by 2025.
Key Institutions and Their Roles in Air Defence and Counter-Drone Operations
The Defence Research and Development Organisation (DRDO) leads R&D in air defence and counter-drone technologies, exemplified by the ‘Droni’ anti-drone system. The Indian Air Force (IAF) operationalises these technologies and develops doctrinal frameworks for integrated air defence. The Indian Navy (IN) addresses maritime air defence and drone threats along the coastline. The Ministry of Defence (MoD) formulates policies and oversees procurement, while the Directorate General of Civil Aviation (DGCA) regulates civilian drone operations and airspace management. The National Technical Research Organisation (NTRO) provides intelligence and electronic warfare support against drone threats.
- DRDO: R&D of counter-drone and air defence systems.
- IAF: Deployment and doctrinal development of air defence.
- IN: Coastal and maritime drone threat mitigation.
- MoD: Policy and procurement oversight.
- DGCA: Civil drone regulation and airspace control.
- NTRO: Intelligence and electronic warfare support.
Technological and Tactical Challenges in India’s Air Defence
India’s air defence architecture currently suffers from limited integration between conventional systems like surface-to-air missiles (SAMs) and emerging counter-drone technologies, leading to delayed threat detection and response. The fragmented regulatory framework between MoD and DGCA impedes swift operational deployment of counter-drone measures. Additionally, drones’ small size, low radar cross-section, and ability to swarm complicate detection and neutralisation. The IAF’s plan to acquire 10 new long-range SAM systems by 2025 aims to bolster conventional air defence but must be complemented by layered counter-drone capabilities.
- Delayed integration between conventional air defence and counter-drone tech.
- Regulatory fragmentation between MoD and DGCA hinders rapid deployment.
- Small drone signatures challenge radar and sensor detection.
- Swarm drone tactics require AI-enabled rapid response systems.
- Procurement of long-range SAMs insufficient without counter-drone layers.
Comparative Analysis: Lessons from Israel’s Multi-Tiered Air Defence
Israel’s integrated air defence architecture, combining the Iron Dome for rocket interception and the Drone Dome for UAV threats, achieves over 90% interception success (Israel Defense Forces data, 2023). It employs layered radar networks, AI-enabled threat classification, and kinetic interceptors, enabling rapid, automated responses to diverse aerial threats. India can adapt this model by tailoring multi-layered defence systems to its geographic and threat environment, integrating indigenous AI-based detection with kinetic and electronic countermeasures.
| Aspect | Israel | India (Current) | India (Proposed) |
|---|---|---|---|
| Air Defence Layers | Multi-tiered: Iron Dome, Drone Dome, Patriot | Conventional SAMs, limited counter-drone | Integrated SAMs + AI-enabled counter-drone systems |
| Detection Technology | Advanced radar + AI threat classification | Radar-focused, limited AI integration | Enhanced radar + AI + electronic warfare sensors |
| Response Speed | Automated, rapid kinetic interception | Manual/slow coordination | Automated, layered kinetic and electronic neutralisation |
| Regulatory Coordination | Unified military control | Fragmented MoD-DGCA roles | Integrated command and regulatory framework |
Way Forward: Strategic and Operational Recommendations
- Doctrine Overhaul: Revise air defence doctrine to integrate conventional and counter-drone systems under unified command.
- Regulatory Harmonisation: Establish joint MoD-DGCA task force for streamlined drone airspace management during conflicts.
- Technology Integration: Invest in AI-enabled multi-sensor detection and electronic warfare capabilities to counter drone swarms.
- Indigenous Development: Scale up ‘Make in India’ initiatives for counter-drone tech, leveraging DIO-supported start-ups.
- Procurement Strategy: Complement long-range SAM acquisitions with short-range kinetic and non-kinetic counter-drone systems.
- Training and Simulation: Enhance IAF and IN training with realistic drone threat scenarios and rapid response drills.
