New Delhi (Gurpreet Singh): Amid a sharp rise in the use of small, hard-to-detect unmanned aerial systems, the Indian Army has moved to fast-track the acquisition of automated “drone catcher” platforms capable of neutralising hostile drones using net-based interception technology.
In a recent Request for Information (RFI) issued by the Ministry of Defence, the Army highlighted the rapidly expanding threat posed by low radar cross-section drones, including those deployed individually or in swarms. Such systems, officials noted, are increasingly difficult to track using conventional radar networks, necessitating dedicated countermeasures.
Multi-Layered Counter-Drone Architecture
The proposed Drone Catcher System (DCS) is expected to function either independently or alongside existing air defence and counter-UAS assets. Designed for deployment across varied operational environments, the system must combine surveillance, detection, tracking and engagement capabilities.
Each unit is envisioned to include:
A high-performance sensor suite
A ground control station (GCS)
A microprocessor-driven targeting module
Four autonomous interceptor drones equipped with net capture mechanisms
The net-equipped drones will be tasked with physically ensnaring or disabling hostile aerial targets, offering a “hard-kill” solution that minimizes collateral damage compared to explosive interceptors.
Advanced Detection and Targeting
According to specifications outlined in the RFI, the system’s primary sensor should be based on electronically scanned array technology or a superior alternative. It must provide 360-degree airspace coverage and be capable of simultaneously detecting and tracking at least 20 drone-sized targets within a minimum radius of four kilometres.
The sensor is required to prioritise and designate threats automatically, relaying targeting data to the interceptor drones through the GCS. Integration with the Army’s existing command and control infrastructure is also mandatory, including compatibility with the Akashteer control and reporting module. Additionally, the system must meet cybersecurity standards set by the Army Cyber Group to operate securely on the Army Data Network.
Autonomous Interception and Electronic Warfare
The drone catcher platforms are expected to operate autonomously once target information is received. After acquiring the hostile drone, the interceptor will deploy a net-based capture system to disable or bring down the target.
Beyond physical interception, the system will incorporate an electronic warfare sub-system. This jammer component will enable radio frequency denial, selective navigation disruption, and Global Navigation Satellite System (GNSS) deception across standard and non-standard frequency bands. The design must allow for both “soft-kill” electronic measures and “hard-kill” physical interception to function simultaneously without operational interference.
All-Terrain, All-Weather Deployment
The Army has stipulated that the system be robust enough for operations across India’s diverse terrain — from deserts and coastal regions to high-altitude areas up to 15,000 feet. It must function effectively in temperatures ranging from minus 15°C to 45°C.
Defence observers say the move underscores the growing concern within security establishments over the tactical use of small drones for reconnaissance, smuggling, and potential attacks on sensitive installations. By prioritising automated net-based interceptors, the Army appears to be seeking a cost-effective and scalable response to the evolving drone battlefield.
If inducted, the new system could significantly enhance India’s layered air defence posture against low-altitude aerial threats.
