In late May 2026, Silent Mesh deployed a four‑sensor passive acoustic array operated by a single person that detected and tracked combat‑grade FPV drones in real time during an official Ukrainian Ministry of Defence crash test (BRAVE1 / Snake Island Institute), including in rain and wind conditions.

Silent Mesh’s acoustic detection system was selected and tested at a Ukrainian Ministry of Defence BRAVE1 crash‑test event, where out of fourteen participants it ranked among the top four solutions able to produce near‑real‑time three‑dimensional coordinates of targets, validating its concept against competing counter‑UAS offerings.

On June 9, 2026, Silent Mesh published a public demonstration post showing FPV combat drones being detected and tracked by its dense mesh of fiber‑connected microphones designed specifically for fiber‑optic guided FPV drones that emit no RF, fly below radar, and cannot be jammed.

By August 2026, Silent Mesh listed its headquarters at Avenida Infante Dom Henrique 143, Edificio 10, S.05, Lisbon, Portugal, on corporate and registry profiles, indicating formal establishment of a physical office location aligned with its defense and space manufacturing positioning.

During a BRAVE1 crash‑test event in Ukraine described in an August 10, 2026 article, Silent Mesh’s acoustic system was reported as being selected among the top four out of fourteen participants that could deliver almost real‑time three‑dimensional target coordinates, albeit with shorter range than some competitors but significantly lower sensor cost.
