Strengthening National Air Defence
Indigenous Shield for Delhi Air Defence: India is preparing to deploy an indigenous Integrated Air Defence Weapon System (IADWS) to protect Delhi NCR from hostile aerial threats. The system is designed to counter missiles, drones, and fast-moving aircraft, reflecting a growing focus on strengthening internal airspace security. This move aligns with the broader national vision of self-reliant defence capability.
Multilayered Architecture
The indigenous IADWS integrates multiple layers of defence. A major component is the Quick Reaction Surface-to-Air Missile (QRSAM), known for its high mobility and quick interception capability. This helps in neutralising medium-range threats swiftly in crowded urban airspace.
Static GK fact: The QRSAM is developed by DRDO and has a range of about 25–30 km.
India will also deploy VSHORADS, a system engineered to counter low-flying drones, helicopters, and slow-moving aircraft. This ensures coverage at very short ranges where larger missile systems are less effective. Together, these layers create a seamless defence umbrella around the capital.
Integrated Command and Control
A critical pillar of the IADWS is its advanced command-and-control grid, linking sensors, launchers, and radar units. The idea is to create a single operational picture for quick decisions during high-speed engagements.
Static GK Tip: India’s primary military radar development agency is the Defence Electronics Research Laboratory (DLRL), part of DRDO.
This network-centric approach ensures quicker detection, coordinated responses, and minimal reaction time during emergencies.
Strategic Lessons from Operation Sindoor
The urgency for this indigenous deployment intensified after Operation Sindoor (May 2025), when Pakistan reportedly attempted to target Indian assets. The incident highlighted vulnerabilities in strategic zones, prompting accelerated security measures for the capital. The indigenous system therefore serves both operational and symbolic functions by demonstrating India’s readiness and technological advancement.
Shift from the NASAMS-II Plan
India’s move marks a shift from earlier plans to procure NASAMS-II, a US-built defence system used to secure Washington D.C. Negotiations for the system were paused after the high acquisition cost. The pivot toward a domestic solution supports cost efficiency, long-term autonomy, and Atmanirbhar Bharat goals.
Static GK fact: NASAMS-II is jointly developed by Raytheon of the US and Kongsberg of Norway.
Boost to Defence Manufacturing
The deployment will be handled by the Indian Air Force, while DRDO and associated production agencies will manage integration. This strengthens India’s defence manufacturing ecosystem and promotes indigenous innovation. It also positions India to reduce import dependency in critical security sectors.
