British Army Tests Game-Changing UK-Made Radiofrequency Weapon to Defeat Drone Swarms

In a major step forward for modern warfare, the British Army has successfully tested a UK-developed Radiofrequency Directed Energy Weapon (RF DEW) that can take down entire swarms of drones in an instant. This breakthrough system, which uses high-frequency radio waves to disable or destroy the electronic components of drones, promises a powerful, low-cost defence solution in an era of increasing unmanned aerial threats.

During the recent trials, the RF DEW system tracked and neutralised more than 100 drones, including two swarms brought down in a single engagement. The system caused drones to malfunction or crash by interfering with their electronics, and it did so with near-instant precision. Remarkably, it is estimated that each "shot" from this advanced weapon costs just 10 pence — making it far more economical than conventional air defence missiles, which can cost thousands or even millions per round.

The UK Government has already invested over £40 million into the development of this cutting-edge technology. More than 135 highly skilled jobs are being supported across Northern Ireland and the South-East of England thanks to this investment, highlighting not only its strategic military value but also its role in boosting the national economy.

Sgt Mayers of the 106 Regiment Royal Artillery made history during the trials by becoming the first British soldier to successfully take down drones using this radiofrequency weapon. He praised the system, saying it was easy to learn and use, and expressed optimism that with further enhancements in range and power, it could become a vital tool in the UK's Layered Air Defence strategy.

The weapon’s development is being led by Team Hersa — a collaboration between the UK Ministry of Defence’s procurement wing, the Defence Science and Technology Laboratory (DSTL), and a consortium of British industry partners headed by Thales UK. Thales employs around 100 experts in Northern Ireland on this project, with another 30–35 supporting roles in Chelmsford, Essex. The company is known for its leadership in airspace protection systems and continues to advance this technology alongside government researchers.

Nigel MacVean, Managing Director at Thales Integrated Airspace-protection Systems, emphasized the importance of the program, stating that Thales remains committed to pushing the boundaries of what’s possible in this field. The RF DEW system, according to him, represents a leap forward in counter-drone technology and showcases the UK’s innovation potential.

The successful trial comes at a time when the use of drones in conflicts is surging. Just last year, Ukraine faced over 18,000 drone attacks. Such figures underline the urgency for modern defence solutions capable of protecting troops and assets from low-cost, mass-produced aerial threats.

As part of its broader “Plan for Change,” the UK Government is set to channel at least 10% of its defence equipment spending into novel technologies like RF DEW starting from 2025–26. This approach not only aims to maintain the UK's strategic edge but also to support home-grown innovation and create economic opportunities nationwide.

Defence Minister Maria Eagle described the trial as a shining example of British innovation. She reiterated that investments in defence technology are not only about national security but also about driving growth across towns and cities in the UK.

In today’s evolving battlefield, where drones can be deployed quickly and in large numbers, the RF DEW system offers a timely and effective solution. If further developed and deployed, it could become a core component of the UK's future defence framework — a silent, precise, and affordable weapon against one of modern warfare’s most rapidly growing threats.
