Modern battlefields increasingly demand rapid detection of hostile fire to protect personnel and improve response times. Advances in lightweight, mobile surveillance technology are shaping how armed forces enhance force protection and operational awareness.
The Ministry of Defence confirmed on 14 February 2026 that an £18.3 million Army contract with Leonardo UK will accelerate delivery of the SONUS acoustic weapon detection system by five years.
The lightweight system detects gunfire, mortars and explosions without emitting an electronic signature and will be rolled out to frontline troops within 12 months, sustaining 250 UK jobs and supporting 29 small and medium-sized enterprises.
Early Delivery of SONUS to Frontline Troops
The Army has accelerated procurement of the SONUS acoustic weapon detection system by five years. The £18.3 million contract enables earlier deployment to frontline units.
The rollout will provide additional battlefield detection capability while supporting operational readiness. Delivery to 5th Regiment Royal Artillery is scheduled within the next year.
- Five-year acceleration of procurement timeline
- £18.3 million contract value
- Deployment to 5th Regiment Royal Artillery
Capability and Operational Advantages
SONUS detects acoustic pressure waves from gunfire, mortars and explosions. This allows forces to locate hostile fire and respond more effectively.
The system weighs 70% less than its predecessor and can be deployed in under three minutes. It operates without emitting an electronic signature, enabling covert use and reducing exposure to enemy targeting.
- 70% lighter than predecessor system
- Deployable in under three minutes
- Passive acoustic detection without electronic signature
Industrial Impact and UK Supply Chain
The contract sustains 250 jobs across the UK, including roles at Leonardo’s Basildon site. It also supports 29 small and medium-sized enterprises within the defence supply chain.
The procurement takes place alongside the largest sustained increase in defence spending since the end of the Cold War, with spending set to reach 2.6% of GDP from 2027. The announcement links operational delivery with industrial support and employment across the country.
