Layered defence: How Britain is pushing again in opposition to swarms of low cost killer drones reshaping trendy warfare

The RAF has warned that unmanned plane are actually a “routine feature” of the battlefield, because it rolls out new methods designed to detect, disrupt and destroy them earlier than they’ll hit crucial infrastructure.

From Ukraine’s entrance traces to the Red Sea and the Gulf, low cost, mass-produced drones are getting used to harass, surveil and strike targets with a frequency that may have been unthinkable even 5 years in the past.

Air Commodore Paul Hamilton, Commandant General of the RAF Regiment, put it bluntly: “Drone activity is now a routine feature of the operating environment.”

That actuality has been pushed house by Ukraine, the place drones have been used to strike every thing from armoured autos to airbases deep behind the entrance line. Western defence officers say comparable techniques are actually being adopted by Iranian-backed teams focusing on army websites and delivery routes.

British bases aren’t immune. Installations linked to US and UK operations, together with RAF Fairford and Diego Garcia, are more and more seen by adversaries as reliable targets in a wider confrontation with the West.

In response, the RAF is deploying a layered defence system constructed round early detection, digital disruption and, if obligatory, direct interception.

And the system works, British air defence troops have already been compelled to place it into motion. RAF Regiment items defending allied bases close to Erbil in Iraqi Kurdistan have shot down greater than 50 Iranian drones utilizing Rapid Sentry missile launchers, based on defence sources, a determine understood to be considerably increased than the quantity intercepted by RAF Typhoon and F-35B jets working in the identical theatre.

The ground-based system, quietly procured in 2022, fires light-weight missiles at supersonic pace over distances of as much as 5 miles and is used when digital measures fail.

The troops, drawn from 2 Force Protection Wing based mostly at RAF Leeming, are a part of a wider coalition effort to detect, observe and neutralise drone threats, highlighting how incessantly these methods are actually being utilized in dwell operations.

At the centre of that may be a counter-drone system referred to as ORCUS, which makes use of radar, radio frequency sensors and long-range thermal imaging to trace drones approaching protected websites.

The goal is to determine threats early sufficient to resolve methods to take care of them earlier than they attain delicate areas.

“Early detection of hostile drones is vital,” Hamilton mentioned, pointing to the harm precipitated in Ukraine.

Once a drone is detected, RAF personnel can try and disable it utilizing digital warfare. Systems akin to NINJA are designed to intrude with the alerts linking a drone to its operator, doubtlessly forcing it to land or lose management.

Defence sources say this strategy is more and more necessary, because it permits threats to be neutralised with out the necessity to hearth pricey interceptors, and in some circumstances supplies intelligence on how and the place the drone was launched.

If that fails, extra conventional air defence methods are used to shoot the drone down.

The RAF describes this as a “layered” strategy, giving operators a number of choices relying on the kind of menace.

The growth displays a wider problem going through Nato, as militaries adapt to what some analysts describe as “mass drone warfare”.

Recent briefings have highlighted how Western forces danger being outpaced by the size and price of drone assaults, with adversaries in a position to deploy giant numbers of low-cost methods which are tough to trace and costly to intercept.

Ukraine has responded by growing its personal low-cost countermeasures, together with interceptor drones, a mannequin now being carefully studied by allied forces.

RAF Regiment items are working with worldwide companions to make sure their methods can function collectively, sharing information and coordinating responses throughout joint operations.

Officials say that cooperation will probably be crucial if a number of bases or areas come beneath simultaneous drone assault.

Airbases stay central to UK army operations, supporting every thing from Typhoon patrols within the Middle East to wider NATO missions.

But they’re additionally more and more uncovered. Rather than large-scale missile strikes, defence planners now see persistent drone exercise, surveillance, disruption and occasional assaults, because the extra probably menace.

For the RAF, the problem isn’t just stopping a single drone, however coping with the potential of a number of methods working without delay, usually cheaply, and generally with believable deniability.

Which is the place issues get uncomfortable. Because whereas the RAF’s new methods are designed to maintain tempo, the broader pattern is shifting in the other way, in direction of cheaper, extra quite a few and harder-to-stop threats.
