The Indian Army is set to enhance its precision strike capabilities with the induction of the Nagastra-1R loitering munition, an indigenously designed and developed "suicide drone." Solar Defence and Aerospace Limited (SDAL) has received an order for approximately 450 of these systems, marking a significant step towards self-reliance in defense technology under the "Make in India" initiative.

The Nagastra-1R, like its predecessor the Nagastra-1, is designed to function as an aerial ambush system. It can loiter over a target area, identify targets, and then execute precision strikes with GPS-enabled accuracy. In "kamikaze mode," the drone neutralizes threats by directly striking the target, destroying itself in the process, achieving accuracy of within 2 meters.

One of the key features of the Nagastra-1R is its reusability. Unlike similar systems, the Nagastra-1R can be recovered and reused if a mission is aborted or the target is not detected. This is made possible by a parachute recovery mechanism, offering a cost-effective advantage. The launcher systems are also fully reusable.

Weighing approximately 9 kg, the Nagastra-1R is a man-portable system, with the entire setup (including the ground control station, communication control unit, payload compartment, and pneumatic launcher) weighing around 30 kg and distributed across two rucksacks. This allows for easy deployment by infantry units in the field.

The drone is equipped with day and night surveillance cameras, providing real-time intelligence and targeting information. It carries a 1 kg high-explosive warhead, capable of neutralizing soft-skin targets. Its electric propulsion system ensures a low acoustic signature, making it difficult for enemies to detect at altitudes above 200 meters.

The Nagastra-1R has a range of 15 km with man-in-loop control, allowing for real-time operator input, and an extended range of up to 30 km in autonomous mode. It has an endurance of 30 minutes, which allows it to loiter over a target area, identify threats, and strike effectively. It can also operate at high altitudes, reportedly over 4,500 meters, making it difficult to detect by radar.

Over 75% of the Nagastra-1R's components are indigenously developed, a collaborative effort between Economics Explosives Ltd (EEL), a 100% subsidiary of Solar Industries, and Z-Motion Autonomous Systems Pvt Ltd, Bengaluru. The system has proprietary encryption for both video and telemetry communication, ensuring secure operation.

The Nagastra-1R has been tested in various locations, including Ladakh and Babina, demonstrating its operational capabilities in diverse terrains and conditions. The Indian Army has already inducted the Nagastra-1, and the first batch of 120 units was delivered in 2024. The completion of the 480-unit order underscores Solar Defence's ability to meet stringent military timelines and quality standards.

The deployment of the Nagastra-1R is expected to significantly enhance the Indian Army's operational capabilities, particularly along the borders with Pakistan and China. The drones are designed for precision strikes on enemy training camps, launch pads, and infiltrators, reducing the risk to soldiers.

Loitering munitions like the Nagastra-1R have proven to be a force multiplier in modern warfare, as demonstrated in conflicts across the world. Their ability to conduct precision strikes, combined with their reusability and indigenous design, makes them a valuable asset for the Indian Army.
