How the Igla-S works
The Igla-S is a man-portable, shoulder-launched surface-to-air missile (SAM) system that uses infrared (IR) homing to lock onto the heat signatures of aerial targets. Its compact form makes it ideal for mobile ground units in high-threat zones. Once fired, the missile homes in on the target's engine heat, making it effective even against small, fast-moving threats like drones and helicopters. It is capable of engaging targets up to 6 km away and at altitudes of up to 3.5 km.
This advanced variant improves upon the earlier Igla models — already in service since the 1990s — offering better resistance to countermeasures and improved seeker accuracy. The Indian Army has also refurbished older stockpiles through a domestic defence firm to extend their operational life.
Why it matters now
The new systems are being rushed to formations deployed along the western border, amid heightened vigilance following the April 22 Pahalgam terror attack. With drones increasingly used for reconnaissance and attacks, including by the Pakistan Army, short-range missile systems like Igla-S are crucial to securing Indian airspace.
To further bolster defences, the Army has reportedly floated a tender for buying 48 more launchers and around 90 missiles of the VSHORADS (IR) under fast-track procedures. The Indian Air Force has also opted for a similar procurement to upgrade its air defence network.
Drone threats and countermeasures
Apart from the Igla-S, the Army has deployed the indigenous Integrated Drone Detection and Interdiction System (IDD&IS), which can "detect, jam, spoof and kill drones from a distance of over 8 kilometers," according to officials. "The systems are also fitted with lasers which can burn and bring down drones,” they said.
In a recent incident, an Army Air Defence unit successfully downed a Pakistani Army drone using these systems near the 16 Corps zone in Jammu.
What's next in air defence
The Defence Research and Development Organisation (DRDO) is developing a longer-range, high-powered directed energy weapon that can take down larger UAVs, cruise missiles, and even aircraft during conflict scenarios. The Army is also eyeing new low-level transportable radars to improve detection of aerial threats flying under conventional radar coverage.
