Bhargavastra Counter-Drone System

Bhargavastra is an indigenous, vehicle-mounted, multi-layered Counter-Swarm Drone System developed by Solar Defence and Aerospace Ltd. (SDAL) for the Indian Army. It was demonstrated in Nagpur on 24 July 2026 during a Make-II programme status review.

Counter-Drone Warfare

Counter-drone systems are designed to detect, track, identify, and neutralise hostile unmanned aerial vehicles (UAVs). Bhargavastra is built as a hard-kill system, which means it destroys the target rather than only jamming its signals.

• Weaponised drones are UAVs fitted with explosives, sensors, or attack payloads.
• Loitering munitions are air-launched weapons that can remain airborne before striking a target.
• Drone swarms are groups of multiple drones operating in a coordinated manner.

System Features

Bhargavastra uses a dual-layer kill mechanism. The first layer uses unguided micro-rockets with a lethal radius of 20 metres, and the second layer uses precision-guided micro-missiles with an interception range of up to 2.5 kilometres. The system can detect larger UAVs up to 10 kilometres and smaller drones up to 6 kilometres. It integrates radar, Electro-Optical/Infrared (EO/IR) sensors, and passive radio-frequency detectors for target acquisition.

Command, Control and Trial Status

During the demonstration, the sensors detected and tracked a drone swarm, and the C4I suite generated a real-time air picture and assigned targets to the launcher. Actual rocket firing was not carried out at the facility because of safety reasons. SDAL stated that internal trials for Bhargavastra would be completed within two to three months from 24 July 2026. The system is described by its developers as one of the first fully integrated, vehicle-mounted, multi-layer counter-swarm drone systems with dedicated swarm-neutralisation capability.

Important Facts for Exams

• Make-II is a category under the Defence Acquisition Procedure for industry-funded prototype development.
• EO/IR sensors are used for day and night surveillance and target detection.
• C4I stands for Command, Control, Communications, Computers and Intelligence.
• Loitering munitions are also called suicide drones in military terminology.

Sudarshan Chakra Programme

Bhargavastra is intended to support the proposed Sudarshan Chakra air defence system, which is projected for development by 2030. The planned layered ranges mentioned for the programme are 2.5 kilometres, 6 kilometres, and 25 kilometres.
