Introduction: Emerging Aerial Threats and India’s Air Defence Imperative
Since 2020, India has witnessed over 300 drone incursions along its borders, underscoring critical vulnerabilities in its air defence architecture (Indian Express, 2024). The proliferation of low Radar Cross Section (RCS) drones, including surveillance and armed variants, demands a strategic overhaul integrating detection, neutralization, and doctrinal reforms. The Ministry of Defence (MoD) and Defence Research and Development Organisation (DRDO) have initiated steps, yet the absence of a dedicated counter-drone framework hampers timely threat mitigation. This evolving threat landscape necessitates revisiting India’s air defence strategy to protect critical military and civilian assets effectively.

Legal and Constitutional Framework Governing Air Defence and Drone Countermeasures
Article 246 of the Constitution places defence under the Union List, empowering Parliament to legislate on air defence and related security measures. The Defence of India Act, 1962 (amended) provides statutory authority for wartime defence actions, including airspace protection. The Indian Arms Act, 1959 regulates weapons, indirectly impacting drone countermeasures involving kinetic interceptors. The MoD formulates policies under the Defence Procurement Procedure (DPP) 2020, guiding acquisition and indigenous development of air defence systems. Currently, no specific judiciary precedents address drone countermeasures, reflecting a nascent legal domain.
- Article 246: Central legislative power on defence and airspace security
- Defence of India Act, 1962: Wartime defence regulations including airspace control
- Indian Arms Act, 1959: Controls weapons used in air defence and counter-drone operations
- Defence Procurement Procedure 2020: Framework for acquisition emphasizing Make in India and advanced technologies
Economic Dimensions: Budgetary Allocations and Indigenous Production
The Union Budget 2023-24 allocated ₹5.94 lakh crore (~USD 72 billion) to defence, with approximately 15% earmarked for capital expenditure including air defence modernization (Union Budget 2023-24). India’s drone market is projected to grow at a 15% CAGR, reaching USD 885 million by 2025 (ResearchAndMarkets.com), highlighting the dual-use nature of drones. Indigenous production under the Make in India initiative and Defence Acquisition Council (DAC) approvals aim to reduce the current 60% import dependency for air defence systems. DRDO’s development of the Akash missile system and anti-drone technologies exemplifies this push towards self-reliance.
- ₹89,100 crore capital expenditure for modernisation including air defence (2023-24)
- Projected drone market growth at 15% CAGR to USD 885 million by 2025
- ~60% import dependency for air defence systems; targeted reduction via Make in India
- DRDO’s Akash missile: 25 km range, multi-target engagement capability
Institutional Roles in Air Defence and Counter-Drone Operations
The Defence Research and Development Organisation (DRDO) leads indigenous development of air defence and anti-drone technologies, including the recently tested Anti-Drone System with a 90% neutralization success rate (DRDO Press Release, 2023). The Indian Air Force (IAF) operates advanced surface-to-air missile (SAM) systems and plans to raise 21 squadrons by 2030 (MoD Annual Report, 2023). The Indian Army (IA) manages ground-based air defence and integrates counter-drone tactics at the tactical level. The Ministry of Defence formulates policies and oversees procurement, while the Directorate General of Aeronautical Quality Assurance (DGAQA) ensures equipment standards. The Directorate General of Civil Aviation (DGCA) regulates civilian drone usage, a critical factor in airspace security.
- DRDO: Indigenous R&D of air defence and anti-drone systems
- IAF: Primary operator of SAMs and aerial counter-drone platforms
- Indian Army: Ground-based air defence and tactical counter-drone integration
- MoD: Policy formulation, procurement authority
- DGAQA: Quality assurance for defence equipment
- DGCA: Regulates civilian drone operations affecting security
Technological and Tactical Challenges in Countering Drone Threats
India’s current air defence doctrine lacks an integrated counter-drone framework combining electronic warfare (EW), kinetic interceptors, and AI-enabled threat assessment. This fragmentation results in delayed detection and neutralization of low-RCS drones, which can evade conventional radar and missile systems. The increase in drone incursions, especially from Pakistan’s deployment of Chinese CH-4 drones increasing aerial threats by 35% on the western border (SIPRI Arms Transfers Database), demands rapid adaptation. DRDO’s Anti-Drone System and Akash missile provide partial solutions, but multi-layered detection and neutralization capabilities remain underdeveloped.
- Low-RCS drones evade traditional radar and SAM detection
- Fragmented doctrine with limited integration of EW and kinetic systems
- AI-enabled threat assessment tools underutilized
- Increased drone threats from adversaries’ advanced UAV deployments
Comparative Analysis: India vs Israel’s Integrated Air Defence Approach
| Aspect | India | Israel |
|---|---|---|
| Doctrine | Fragmented, lacks dedicated counter-drone framework | Multi-layered, integrated counter-drone and missile defence |
| Systems | Akash missile, DRDO Anti-Drone System (tested) | Iron Dome, David’s Sling, Patriot batteries |
| Interception Success | Not officially quantified; partial success in tests | ~90% interception success against drone swarms (2023 Gaza conflict) |
| Technological Integration | Limited AI and EW integration | Advanced AI-enabled threat assessment and EW capabilities |
| Procurement | 60% import dependency; Make in India push ongoing | Highly indigenous with selective imports |
Way Forward: Strategic and Operational Imperatives
- Develop a unified counter-drone doctrine integrating EW, kinetic, and AI-enabled detection systems
- Accelerate indigenous R&D and production under DRDO and private industry partnerships
- Enhance real-time data sharing and joint operations between IAF, IA, and intelligence agencies
- Strengthen regulatory framework for civilian drone operations via DGCA to prevent misuse
- Invest in multi-layered air defence architecture inspired by Israel’s model for layered interception
- Upgrade radar and sensor networks to detect low-RCS and swarm drone threats effectively
