The British Army has taken a major step forward in counter-drone technology by successfully testing a new radio-wave weapon designed to knock out swarms of drones. In a recent trial, soldiers used the Radiofrequency Directed Energy Weapon (RF DEW) to neutralize over 100 drones, including two swarms in a single engagement—the largest such exercise ever conducted by the British Army. This marks the first time British forces have used this type of weapon to defeat drone swarms, highlighting its potential as a game-changer in modern air defense.
How the Technology Works
The RF DEW works by firing high-frequency radio waves that disrupt the sensitive electronics inside drones, causing them to crash or malfunction almost instantly. Unlike traditional missile-based defenses, which can be expensive and single-use, the RF DEW can target multiple drones at once for just 10 pence (about 13 cents) per shot. This makes it a cost-effective solution for defending military bases, airports, and other sensitive sites.
The weapon is also easy to operate, requiring only one person to use it, and can be mounted on a vehicle for mobility. Soldiers involved in the trials found the system quick to learn and simple to use, with the ability to take out targets up to one kilometer away.
Potential Drawbacks and Limitations
Despite its promise, the technology has some limitations. The current range is about one kilometer, and the weapon uses a wide beam that cannot distinguish between friendly and enemy drones within its area of effect. This could risk affecting unintended targets. Additionally, while the RF DEW can defeat drones that are resistant to traditional jamming, further development is needed to improve its power and range for broader protection.
Alternatives and the Future of Counter-Drone Defense
Other anti-drone solutions include jammers, lasers, and kinetic interceptors, but these options can be more costly or less effective against large swarms. The British Ministry of Defence has invested over £40 million in developing RF DEW technology, supporting more than 135 skilled jobs across the UK. With continued investment and testing, the radio-wave weapon could soon become a key part of layered air defense strategies.
The successful trial comes as drone swarms are increasingly used in conflicts worldwide, such as in Ukraine, where over 18,000 drone attacks were reported last year. As drone threats evolve, affordable and rapid-response technologies like RF DEW will play a crucial role in protecting military and civilian targets.
