The Indian Air Force (IAF) is advancing its capabilities by developing a ground-based Signal Intelligence (SIGINT) system for all-terrain vehicles, aimed at overcoming challenges in hilly regions where traditional systems struggle. This innovative system, which includes drone support for enhanced situational awareness, is crucial for monitoring adversarial activities along India’s northern borders with China and Pakistan. By integrating advanced sensors and communication technologies, the IAF seeks to improve intelligence gathering and electronic warfare capabilities. Collaborations with organizations like DRDO and companies such as BEL and TASL are expected to drive this initiative, reflecting India’s commitment to modernizing its defense strategy in response to evolving threats.

The Ministry of Defense and the Indian Navy have issued a Request For Information (RFI) to procure 40 units of Naval Ship-Borne Unmanned Aerial Systems that can be launched from naval ships and will be used for Coastal/Exclusive Economic Zone (EEZ) surveillance, Signal Intelligence, Target Acquisition and Reconnaissance, anti-piracy and anti-terrorism, and building Maritime Domain Awareness around a task group.

It must have a minimum endurance of more than 10 hours with a basic payload and loitering capability at 5,000 feet and at 100 kilometers range in basic configuration.

Each system is to comprise of two air vehicles, which are modular in design, made of composite material and that can be dismantled/folded for portability and stowage onboard ship (in a container provided along with Remotely Piloted Aircraft (RPA) being supplied. The RPA must be easily assembled onboard the ship.

Kalyani Strategic Systems Limited (KSSL), the defence arm of Kalyani Group, Pune based Indian conglomerate unveiled the unique drone BHARAT 150, a multi-payload, variable mission drone indigenously developed by the group. The X-8 configuration drone is already under testing by the Indian Army in high altitude areas in Leh-Ladakh and performed 8.5 KM with 20 kg payload.

The drone is a vertical take-off and landing (VTOL) Unmanned Aerial Vehicle (UAS), with a maximum take-off weight of 150 kg and empty take-off weight of 58 kg. The craft comes integrated with an indigenously developed radio communication system and Inertial Navigation System (INS) with anti-jamming and anti-spoofing capabilities, making it operational in jamming and GPS-denied environment as well.

The drone’s batteries can give minimum 30 minutes of endurance with a communication link encryption (128 AES) for 50 km – 200 KM. The endurance can be enhanced as per the application.

The water and dust proof Bharat 150 can be used in the temperature range of -30°C to 65°C with an average speed of 50 Km/h and a gust resistance of 15 m/s. It can operate at 1000 m above the take-off ground and is designed to work at 5500 m ASL.

It’s autonomous and electronically stable design makes it suitable for application in Logistics, Search and Rescue, Signal Intelligence and communication intelligence, ISR, Loitering Munition for warhead dropping etc.

Commenting on revelation of the drone, Mr. Rajinder Bhatia, President and CEO Bharat Forge Defence, said, “We are extremely proud to have developed Bharat 150, a state-of-the-art Unmanned Aerial Vehicle. These indigenous achievements further reinforce our commitment towards making the country more self-reliant, additionally the drone can be used across multiple sectors with varied requirements. We are optimistic about its performance and hope for a speedy induction.”
