Context: Emergence of Drone Warfare in Modern Conflicts
Unmanned Aerial Vehicles (UAVs), loitering munitions, and drone swarms have transformed contemporary battlefields since the early 2010s. Recent conflicts such as the Russia-Ukraine war, Nagorno-Karabakh, and Gaza Strip have demonstrated the effectiveness of low-cost drones in saturating air defences and inflicting disproportionate damage on conventional forces. India's current military posture, with approximately 300 UAVs and a fragmented counter-drone doctrine, faces urgent pressure to adapt to these evolving threats to maintain strategic deterrence and operational readiness.

Legal and Constitutional Framework Governing Drone Warfare
India's drone warfare is regulated under multiple statutes. The Defence of India Act, 1962 empowers the government with wartime powers including control over UAVs. The Arms Act, 1959 governs weaponry, extending to armed drones. Cyber and electronic warfare aspects fall under the Information Technology Act, 2000 (Sections 66F and 69) addressing hacking and interception threats posed by drones. Defence technology procurement, including UAVs, follows the Defence Procurement Procedure (DPP) 2020. Article 246 of the Constitution vests Parliament with exclusive legislative power over defence, enabling centralised policy formulation without state interference. No Supreme Court rulings yet clarify drone warfare legality, indicating a nascent jurisprudence.
Economic Dimensions: Budget and Indigenous Production
India’s defence budget for 2023-24 stands at ₹5.94 lakh crore (~$80 billion), with capital expenditure constituting 25%, earmarked for UAVs and missile systems procurement (Union Budget 2023-24). The domestic drone market is projected to grow at a CAGR of 15.6%, reaching $885 million by 2025 (FICCI-EY Report 2022). Indigenous production under 'Make in India' and the Defence Innovation Organisation (DIO) targets reducing the current 70% import dependence for UAVs, enhancing strategic autonomy (DRDO Annual Report 2023). Counter-drone systems market is expected to reach $250 million by 2027, growing at 20% annually.
Key Institutions and Their Roles in Drone Warfare
- DRDO: Develops indigenous UAVs, loitering munitions, and counter-drone technologies.
- Indian Air Force (IAF): Operational integration of drones and air defence against drone swarms.
- Indian Navy (IN): Maritime drone surveillance and anti-drone defence systems.
- Ministry of Defence (MoD): Policy formulation, procurement, and inter-service coordination.
- Defence Innovation Organisation (DIO): Incubates startups and accelerates drone technology innovation.
- Directorate General of Aeronautical Quality Assurance (DGAQA): Ensures quality standards for UAV systems.
Drone Swarm Saturation Threats: Data from Recent Conflicts
Swarm saturation attacks deploying over 300 drones simultaneously have overwhelmed advanced air defence systems globally (CSIS Report 2023). In the Russia-Ukraine conflict, over 1,200 First-Person-View (FPV) drones disabled 500+ armoured vehicles (IISS Military Balance 2023). The Nagorno-Karabakh war attributed 75% of battlefield kills to loitering munitions (SIPRI 2021). India’s current UAV fleet is 300 units, with plans to expand to 1,000 by 2030 (MoD Annual Report 2023). Existing air defence systems like the Akash missile have a reload time of 30 seconds, inadequate against rapid drone swarms (DRDO Technical Bulletin 2023).
Comparative Analysis: India and Israel’s Drone Warfare Strategies
| Aspect | India | Israel |
|---|---|---|
| Drone Fleet Size | ~300 UAVs; target 1,000 by 2030 | Several thousand UAVs with combat and surveillance roles |
| Counter-Drone Systems | Fragmented; developing indigenous systems | Integrated multi-layered systems: Iron Dome, Drone Dome |
| Interception Success Rate | Data unavailable; limited against swarms | ~90% interception against swarm attacks (Israel MoD 2023) |
| Operational Integration | Separate service-level efforts; no unified doctrine | Joint command integrating radar, EW, and kinetic interceptors |
| Indigenous Production | 70% import dependence; Make in India initiatives ongoing | High indigenous R&D and production capabilities |
Critical Gaps in India’s Drone Warfare Strategy
- Lack of a unified counter-drone doctrine integrating Army, Navy, Air Force, and civilian agencies.
- Fragmented operational responsibilities delay response to swarm saturation threats.
- Limited indigenous production capacity prolongs import dependence and supply chain vulnerabilities.
- Existing air defence systems inadequately adapted to counter low-RCS (Radar Cross Section) drones and high-speed swarms.
- Insufficient investment in electronic warfare (EW) and artificial intelligence (AI) integration for drone detection and neutralisation.
Way Forward: Strategic and Operational Imperatives
- Formulate a comprehensive, joint-service counter-drone doctrine encompassing detection, jamming, and kinetic interception.
- Accelerate indigenous development of cost-effective anti-drone systems leveraging AI, EW, and sensor fusion technologies.
- Upgrade legacy air defence platforms with rapid-fire capabilities and automated threat response to counter saturation attacks.
- Enhance inter-agency coordination including civil aviation, cyber security, and intelligence agencies for holistic drone threat management.
- Expand Defence Innovation Organisation’s role in fostering startups and MSMEs for agile drone technology solutions.
- Increase budgetary allocation for capital expenditure focused on UAVs and counter-drone systems within the defence budget.
- The Defence of India Act, 1962 governs wartime powers including drone deployment.
- The Arms Act, 1959 does not apply to unmanned aerial vehicles.
- The Information Technology Act, 2000 addresses cyber threats posed by drones.
Which of the above statements is/are correct?
- Swarm attacks deploy hundreds of drones simultaneously to overwhelm air defences.
- India’s Akash missile system has a reload time sufficient to counter large drone swarms effectively.
