Integrated Air Defence Weapon System (IADWS)

India’s Integrated Air Defence Weapon System is a new Era in Multi-Layered Defence. DRDO successfully conducted the first flight tests of the Integrated Air Defence Weapon System (IADWS) in 2025. Read here to learn more.

India’s national security landscape is evolving rapidly in response to emerging aerial threats, including advanced fighter jets, cruise missiles, and swarms of unmanned aerial vehicles (UAVs).

Recognising this, the Defence Research and Development Organisation (DRDO) successfully conducted the first flight tests of the Integrated Air Defence Weapon System (IADWS) in 2025.

The system represents a paradigm shift in India’s air defence capability, as it integrates missile-based interceptors with directed energy weapons (DEWs) into a multi-layered defensive shield.

What is the Integrated Air Defence Weapon System (IADWS)?

The IADWS is a multi-tiered, networked air defence solution designed to intercept and neutralise a wide range of aerial threats.

• Unlike standalone missile systems, the IADWS combines short-range surface-to-air missiles, man-portable systems, and laser-based weapons under a Centralised Command and Control Centre (C3), ensuring rapid detection, decision-making, and engagement.
• By bringing together kinetic and non-kinetic options, the system provides layered redundancy; if one system fails, the other takes over, ensuring a robust defence.

Three Components of the IADWS

1. Quick Reaction Surface-to-Air Missiles (QRSAM)

• Protects mobile formations of the Army and strategic installations from enemy aircraft, helicopters, and UAVs.
• Key Features:
  • Range: 3 to 30 km.
  • Configured on highly mobile platforms, capable of keeping pace with armoured columns.
  • Equipped with Active Array Battery Surveillance Radar (AABSR) and Active Array Battery Multifunction Radar (AAMFR) for 360° coverage.
  • Search-on-move and track-on-move capabilities allow real-time situational awareness.
  • Fully automated Command and Control system reduces human error and speeds up response time.

QRSAM forms the first active layer of the IADWS shield, engaging targets at medium-short distances.

2. Very Short-Range Air Defence System (VSHORADS)

• Acts as the last line of defence against low-flying aerial threats.
• Key Features:
  • A fourth-generation Man Portable Air Defence System (MANPAD).
  • Designed to neutralise close-range aircraft, helicopters, and UAVs.
  • Lightweight, easily deployable across the Army, Navy, and Air Force.
  • Can be used by infantry units as well as mounted on light vehicles for mobile defence.

VSHORADS provides tactical flexibility, protecting troops and installations where larger systems may not be feasible.

3. Directed Energy Weapons (DEWs)

• Neutralises modern threats like UAV swarms, loitering munitions, and spy drones without expending costly missiles.
• Recent Breakthrough:
  • DRDO’s CHESS laboratory in Hyderabad successfully demonstrated the vehicle-mounted Laser DEW Mk-II(A) in 2025.
  • Capable of damaging UAV structures and disabling sensors within a 3 km range.
• Significance:
  • Offers speed-of-light engagement, critical against fast-moving and multiple threats.
  • Adds an economical layer of defence: one DEW shot costs far less than firing a missile.
  • Places India in an exclusive global club with nations like the US, China, Russia, and Israel.

DEWs mark India’s entry into next-generation warfare technologies, complementing traditional missile systems.

Centralised Command and Control Centre (C3)

• Developed by Defence Research and Development Laboratory (DRDL), Hyderabad.
• Integrates QRSAM, VSHORADS, and DEW into a unified, network-centric system.
• Functions:
  • Detects and tracks threats using integrated radar and sensor networks.
  • Prioritises targets based on threat level.
  • Assigns the appropriate weapon system (missile or DEW) for interception.
• Ensures minimal reaction time, a critical factor in modern air defence.

Why is IADWS Significant for India?

Multi-Layered Defence Against Diverse Threats

• Protects against fighter jets, UAVs, cruise missiles, helicopters, and drone swarms.
• Redundancy ensures that if one system fails, another layer engages the target.

Response to Modern Warfare

• Recent conflicts, such as in Ukraine and the Middle East, have highlighted the devastating impact of drone swarms and loitering munitions.
• IADWS equips India with tools to counter such asymmetric aerial threats.

Indigenous Capability and Self-Reliance

• Developed entirely by DRDO, showcasing India’s growing defence R&D capacity.
• Reduces dependence on imports, aligning with Atmanirbhar Bharat and defence export goals.

Complements Existing Air Defence Architecture

• India already deploys systems like Akash SAM, S-400 Triumf (imported from Russia), and the upcoming XRSAM.
• IADWS adds another layer, ensuring comprehensive protection from short to ultra-short ranges.

Cost-Effectiveness

• Missiles are expensive; DEWs offer a low-cost-per-shot option.
• Balances affordability with effectiveness, a crucial factor for sustained deployments.

Global Context

• Countries like the US (Iron Dome equivalent systems), Israel, Russia, and China have invested heavily in integrated air defence.
• With IADWS, India joins this league, enhancing its deterrence and warfighting capability.
• The inclusion of DEWs signals India’s seriousness about future warfare domains.

Challenges Ahead

• Scaling up production for large-scale deployment across services.
• Integration with legacy systems like Akash and Pechora.
• Developing longer-range DEWs for greater coverage.
• Ensuring inter-service operability (Army, Navy, Air Force).

Conclusion

The successful flight tests of the Integrated Air Defence Weapon System (IADWS) mark a watershed moment in India’s defence capability.

By blending missile interceptors and directed energy weapons under a centralised command structure, India has taken a decisive step towards a multi-layered, indigenous, and future-ready air defence network.

As aerial threats evolve, the IADWS will serve as both a shield and deterrent, strengthening India’s position as a major military power in the 21st century.
