BEL Confirms Microwave Directed-Energy Weapon Prototype Ready as DRDO-BEL System Advances Through Evaluation

Bharat Electronics Limited has confirmed that an indigenous microwave directed-energy weapon prototype developed jointly with the Defence Research and Development Organisation is ready and undergoing evaluation, marking another step in India’s effort to develop advanced hard-kill systems against drones and other electronically vulnerable airborne threats.

BEL Chairman and Managing Director Manoj Jain disclosed the status of the programme during the company’s Q1 FY 2026-27 investor conference call on July 27, 2026. Responding to a question about BEL’s counter-UAS and directed-energy programmes, Jain said the company already had the microwave DEW prototype ready, although the system remained under evaluation. BEL’s official stock-exchange disclosures confirm that the company published the conference-call transcript following the July 27 interaction.

The development forms part of a wider shift in India’s counter-drone architecture towards systems capable of defeating unmanned aircraft without relying entirely on conventional missiles or ammunition. BEL is pursuing both high-energy laser and microwave-based directed-energy technologies, which offer different mechanisms for disabling hostile drones.

Microwave directed-energy weapons use concentrated electromagnetic energy rather than a projectile. When sufficiently powerful microwave pulses reach an unmanned aircraft, they can interfere with or damage vulnerable electronic components such as processors, communications hardware, navigation systems and flight-control electronics. This approach could become particularly useful against drone swarms, where firing an expensive interceptor missile at every small aircraft may prove operationally and economically inefficient.

The programme is being pursued in partnership with DRDO. Jain said the prototype had been developed jointly with the defence research organisation, reflecting the established model under which DRDO laboratories develop critical technologies while BEL contributes engineering, integration, production capability and eventual industrial scaling.

DRDO already maintains significant expertise in microwave technologies through its Bengaluru-based Microwave Tube Research and Development Centre, or MTRDC. The laboratory forms part of DRDO’s Electronics and Communication Systems cluster, which works across electronic warfare, radar, directed-energy systems and associated technologies. BEL and MTRDC also maintain an established technology-transfer relationship covering advanced microwave components for defence applications.

In January 2026, DRDO publicly displayed a separate high-power microwave counter-UAS prototype developed by MTRDC during the International Conference on Electronic Warfare in Bengaluru. According to Janes, the system had already demonstrated the ability to disable small commercial quadcopters at ranges of about one kilometre, while the development team was working towards a future kill range of up to five kilometres.

The MTRDC prototype was reported to operate in the S-band and generate extremely short high-power microwave pulses. Janes reported a peak pulsed output of approximately 450 MW, with a pulse width of around 20 nanoseconds. Such peak-power figures should not be interpreted like the continuous electrical output of a conventional transmitter because the system produces extremely brief electromagnetic pulses rather than sustaining hundreds of megawatts continuously.

DRDO’s development team said in January that the system had already neutralised Phantom-class commercial quadcopters at approximately one kilometre. Its longer-term objective was to increase effective range and complete additional testing. The January programme schedule envisaged testing concluding around June 2026, although no subsequent official announcement located so far confirms that every planned test concluded on that timetable.

BEL’s July statement is therefore important because it confirms that industrial development has progressed to the point where a joint DRDO-BEL microwave DEW prototype physically exists and is undergoing evaluation. However, BEL has not yet announced formal induction, a production contract or a specific date for Armed Forces user trials.

This distinction separates the microwave programme from BEL’s more mature laser directed-energy weapon systems. Jain said BEL had already received orders during the previous three years for its 2-kW laser-based DEW solution and had delivered roughly 80% of those orders. The microwave system, by contrast, remains at the evaluation stage.

Laser and microwave weapons offer complementary capabilities. High-energy lasers concentrate optical energy on a specific point of a target and can physically damage components or structures when the beam remains accurately focused. High-power microwaves instead attack electronic systems with electromagnetic energy and potentially offer an advantage against multiple small drones within an illuminated area.

That difference makes microwave weapons particularly interesting for future counter-swarm operations. Large numbers of inexpensive drones can create a difficult cost-exchange problem for conventional air defence because each incoming aircraft may cost only a fraction of the missile used to destroy it. A directed-energy weapon powered primarily by electrical energy could potentially engage repeated targets without carrying a large magazine of conventional interceptors.

Such systems are not replacements for missiles, guns or electronic jammers. Weather, range, line of sight, target design and electromagnetic hardening can all affect directed-energy performance. A layered counter-UAS network would therefore normally combine radar and electro-optical detection with electronic warfare, guns, missiles, lasers and microwave weapons depending on the threat.

India has already adopted this layered philosophy in its indigenous counter-drone programmes. Earlier DRDO counter-UAS architectures combined radar and electro-optical sensors with radio-frequency jamming and hard-kill directed-energy options. BEL has served as an important production partner for such systems, giving the company experience in integrating sensors, command systems and effectors into deployable counter-UAS configurations.

The microwave programme could expand that architecture further by providing an indigenous non-kinetic hard-kill option designed specifically around the growing electronic vulnerability of unmanned systems. Its eventual operational value will depend on demonstrated effective range, reliability, target engagement rate, power requirements, mobility and performance against drones designed to resist electromagnetic attack.

BEL’s involvement is also important from an industrial perspective. The Navratna defence PSU already manufactures radars, electronic warfare systems, communications equipment, electro-optics and counter-drone technologies. During Q1 FY 2026-27, BEL reported an order book of ₹72,258 crore as of July 1, 2026, illustrating the scale at which the company can move mature defence technologies into serial manufacture if the Armed Forces approve them.

For now, the microwave directed-energy weapon remains a prototype undergoing evaluation rather than an operationally inducted weapon. No confirmed production quantity, user-trial timetable or deployment date has been announced publicly.

Even with that caution, BEL’s confirmation represents a significant development. India has moved beyond laboratory research in high-power microwave weapons to a stage where DRDO and BEL have produced functioning prototype hardware for evaluation. If the system successfully completes testing and satisfies military requirements, it could add a new indigenous layer to India’s counter-drone defences—one designed not to shoot hostile drones out of the sky with conventional ammunition, but to defeat the electronics that allow them to fly.
