The UK Army is introducing SONUS, a new passive acoustic detection system developed by Leonardo UK, designed to rapidly locate enemy artillery, mortar, and gunfire positions. SONUS listens for acoustic pressure waves such as muzzle blasts, projectile shockwaves, and impact sounds, then triangulates their source using distributed sensors. Because it works passively without emitting signals, the system helps troops remain concealed while still identifying targets more quickly and accurately.
SONUS is also significantly lighter and more portable than earlier systems allowing faster setup in frontline conditions. The British Army plans to equip the 5th Regiment Royal Artillery with the technology, accelerating delivery five years ahead of schedule as part of broader defence modernization efforts. By improving counter-battery response speed and situational awareness, SONUS aims to enhance soldier safety and operational effectiveness on modern, mobile battlefields.
