A new acoustic weapons detection system is being fast-tracked to frontline troops, giving British soldiers the ability to locate and respond to enemy fire with unprecedented speed.
The system, known as SONUS, is now set to reach soldiers five years earlier than originally planned, delivering enhanced battlefield safety and tactical advantage.
Faster, Lighter, Smarter Technology
SONUS represents a major leap in battlefield technology. Weighing 70% less than previous systems, it is not only easier to transport but also deployable in under three minutes. Using advanced acoustic sensors, SONUS detects the sound waves produced by gunfire, mortars, and explosions.
Because the system operates passively—without sending out an electronic signature—it allows troops to detect threats covertly, reducing the risk of being targeted themselves.
This capability enables soldiers to respond more quickly, make informed decisions, and take both defensive and offensive action with confidence.
Boosting UK Defence and Supporting Jobs
The £18.3 million contract awarded to Leonardo UK will sustain 250 jobs across the country, including at Leonardo’s Basildon facility, and support 29 UK small and medium-sized enterprises (SMEs) in the supply chain.
This investment aligns with a broader increase in defence spending, projected to reach 2.6% of GDP by 2027, the largest sustained rise since the Cold War.
Minister Highlights Safety and Growth Benefits
Minister for Defence Readiness and Industry, Luke Pollard MP, emphasized the dual benefits of the accelerated delivery:
“We’ve accelerated our procurement of this equipment by five years to provide additional layers of safety for our personnel through more durable, lightweight systems in a new era of threat. Making defence an engine for growth is a key priority, and this deal sustains jobs across the UK while boosting our Armed Forces.”

SONUS Rollout and Operational Impact
The first SONUS units will be delivered over the next 12 months to the 5th Regiment Royal Artillery, the Army’s Surveillance and Target Acquisition Regiment. Brigadier M Birch, overseeing the Land ISTAR Programme, highlighted the operational impact:
“This investment demonstrates the Army’s commitment to delivering cutting-edge technology to the front line. It will enhance our ability to protect our people and respond to emerging threats, ensuring the Army is ready for future challenges.”
Leonardo’s Expertise in Acoustic Detection
Leonardo UK brings over 40 years of experience in passive acoustic weapon-locating technology. Their systems have been operational with more than 13 armed forces worldwide, many of them NATO members. Olly Manning, Vice President of Mission Systems, commented:
“We look forward to ensuring SONUS provides the British Army with an accurate, robust, and reliable passive detection system that will keep our Armed Forces safe—now and into the future.”
Strategic Defence Goals and Modernisation
This procurement supports both the Strategic Defence Review (SDR) and the Defence Industrial Strategy (DIS). By fast-tracking critical weapon-locating systems, the Army is modernising its capabilities, doubling lethality, and strengthening the UK’s defence industrial base.
The accelerated rollout was made possible by close collaboration between the LAND ISTAR Team, Defence Equipment and Support (DE&S), and Task Force RAPSTONE, demonstrating a coordinated effort to deliver key capabilities quickly.
What’s Next?
-
Full deployment of SONUS across frontline units within 12 months.
-
Continued support for UK SMEs in the defence supply chain.
-
Integration with broader Army modernisation initiatives to enhance battlefield readiness.
-
Monitoring operational impact to inform future defence procurement and technology upgrades.
Summary
The British Army is set to receive the SONUS acoustic weapon detection system five years early, providing soldiers with faster, lighter, and covert tools to detect enemy fire.
The £18.3 million Leonardo UK contract secures 250 jobs, benefits 29 SMEs, and aligns with the UK’s largest sustained defence spending increase since the Cold War.
SONUS deployment will enhance troop safety, operational effectiveness, and the UK defence industrial base while supporting modernisation goals.
