In modern warfare, Swarm Drones have become one of the most unpredictable threats. India now faces the growing challenge of defending its borders and bases against UAV floods: large numbers of small, low-cost drones that can overwhelm traditional air defence systems.
To respond, the country is prioritising the development of low-cost anti-drone missiles that can intercept multiple UAVs at once while keeping expenses minimal. This shift signals a major evolution in India’s defence strategy, combining innovation, cost efficiency, and indigenous production under the Make in India initiative.
Why India Needs Low-Cost Anti-Drone Missiles
The Rise of Swarm Warfare
Drone technology has evolved from surveillance tools to offensive weapons. Swarm drones can launch coordinated attacks, confuse radar systems, and hit critical targets. They are inexpensive, quick to deploy, and easy to modify. These qualities make them dangerous in both military and asymmetric warfare.
Cost Imbalance in Defence Operations
A basic drone may cost only a few lakh rupees, yet neutralising it with a conventional missile can cost crores. This cost asymmetry makes existing air-defence models unsustainable. By developing low-cost hard-kill anti-drone systems, India aims to correct this imbalance and achieve economic as well as tactical superiority.
India’s Strategic Counter-UAV Vision
Layered Defence Model
India’s counter-UAV strategy integrates multiple defence layers:
- Detection Layer: Uses radar, electro-optical, and infrared systems to track drones.
- Electronic Warfare Layer: Employs jammers to block control and GPS signals.
- Hard-Kill Layer: Launches micro-missiles or micro-rockets to physically destroy the remaining drones.
This multi-layered approach increases accuracy while reducing operational costs.
Operational Readiness
The military aims to field mobile anti-drone units that can defend both borders and critical infrastructure. These systems are designed for rapid deployment, high reload speed, and minimal maintenance, ensuring that India can respond quickly to sudden drone intrusions.
The Technology Behind India’s Anti-Drone Missiles
Micro-Missiles and Smart Targeting
Modern micro-missiles use advanced sensors, proximity fuses, and AI-guided targeting. Instead of direct contact, they detonate near the drone, using a directional fragmentation warhead for precision destruction. This makes them ideal against agile UAVs flying in unpredictable patterns.
Indigenous Innovation: Bhargavastra
One of India’s most promising solutions is the Bhargavastra system, developed by Solar Defence & Aerospace Ltd. It features two firing layers:
- Unguided micro-rockets for area suppression.
- Guided micro-missiles for high-value or evasive targets.
The system is capable of salvo firing, releasing multiple interceptors within seconds. Bhargavastra reflects India’s growing capacity for self-reliant defence manufacturing under the Atmanirbhar Bharat initiative.

Global Comparisons
Internationally, systems like Saab’s Nimbrix, Israel’s Iron Beam, and Russia’s Pantsir-SM share similar goals: neutralising Swarm drones efficiently. What makes India unique is its pursuit of affordable, scalable solutions designed for wide deployment across its diverse terrain.

Core Features of an Ideal Indian Anti-Drone Missile
- Low Unit Cost: Every missile should be cheaper than the target it destroys.
- Rapid Salvo Launch: Capable of firing multiple missiles in seconds.
- AI-Assisted Guidance: Machine learning ensures faster and more accurate targeting.
- Lightweight, Portable Design: Easy to deploy across varied terrains.
- Interoperability: Fully compatible with radar and command networks.
- Modular Warheads: Customisable payloads for small or large drones.
Such features make low-cost anti-drone missiles both practical and scalable for India’s long-term defence architecture.
Challenges in Implementing Counter-Drone Technology
Target Identification
Distinguishing hostile drones from friendly or civilian UAVs is complex. Sensor fusion, combining radar with electro-optical and AI systems, is essential to reduce false positives.
Reload and Supply Chain Logistics
Even affordable missiles require a steady supply. India must ensure fast reloading systems and efficient logistics to sustain continuous operations during prolonged drone attacks.
Adapting to Evolving Threats
Adversaries are experimenting with stealth drones, GPS spoofing, and autonomous flight algorithms. This demands constant upgrades to missile software, sensors, and communication protocols to maintain effectiveness.

Economic and Industrial Significance
Boosting Indigenous Production
Developing counter-UAV missiles domestically boosts the local defence sector. It supports collaborations between startups, DRDO labs, and private firms, strengthening the industrial base and reducing import dependency.
Export Potential
Many developing nations face drone-related security challenges. India’s affordable anti-drone missiles could emerge as export-ready products, opening new markets in Asia, Africa, and the Middle East.
Employment and Research Growth
R&D in micro-propulsion, AI-driven target recognition, and defence-grade materials will generate employment for engineers, scientists, and manufacturing specialists. This expansion aligns with India’s long-term defence innovation ecosystem goals.
Integrating Hard-Kill and Soft-Kill Solutions
Effective defence lies in combining hard-kill systems (missiles) with soft-kill systems (jammers, lasers, directed energy weapons).
- Soft-kill systems disable drones silently and are ideal for urban or civilian zones.
- Hard-kill systems ensure complete elimination when drones carry explosives or resist jamming.
By merging these approaches, India achieves a multi-layered defence shield capable of protecting cities, bases, and border zones alike.
The Road Ahead for India’s Counter-Drone Program
Short-Term Priorities
- Complete trials and begin field deployment in high-threat areas.
- Train soldiers for real-time detection and engagement.
- Integrate counter-drone missiles with surveillance systems.
Medium-Term Goals
- Develop vehicle-mounted and naval variants for flexible use.
- Establish production lines for Bhargavastra and similar systems.
- Improve AI-based swarm detection algorithms.
Long-Term Vision
By 2030, India aims to operate a unified Counter-UAV Network that connects radars, missile batteries, and EW systems in real time. Such integration ensures automated responses within milliseconds, reducing human error and improving reaction times.

My Perspective on India’s Defence Transition
In my view, India’s focus on low-cost anti-drone missiles represents a strategic evolution, one that balances technology with economics. Rather than competing on size or firepower, modern warfare rewards nations that innovate faster and spend smarter.
India’s efforts show a clear shift toward intelligent, adaptive defence ecosystems. With indigenous manufacturing, AI-assisted targeting, and modular missile designs, the country is preparing for a future where autonomous drones and automated defences coexist on every battlefield.
Conclusion
The race to counter Swarm drones is shaping the future of warfare. India’s low-cost anti-drone missile initiative demonstrates how innovation, affordability, and national capability can converge to build a sustainable defence model. As threats evolve, so too must the technologies that protect against them.
Through Bhargavastra and other indigenous systems, India is laying the groundwork for global leadership in counter-UAV technology. For defence enthusiasts and strategic planners alike, this is not just about missiles; it is about the future of national security, technological self-reliance, and cost-effective innovation that keeps the skies safe.
