Arcani to Test HARK Acoustic Sensor in Ukraine This May
UK startup Arcani plans to deploy its HARK acoustic sensor in Ukraine for testing in May 2026, enhancing local defense capabilities. The HARK system is intended to complement Ukraine's existing Zvook system, providing additional detection for smaller UAV threats.

Arcani is set to test its HARK (Hostile Acoustic Reconnaissance Kit) acoustic sensor in Ukraine in May 2026. This initiative aims to bolster portable force protection systems as the Ukrainian Third Army Corps seeks enhanced detection capabilities.
HARK is designed to work alongside the Zvook system, which primarily utilizes MEMS microphones for larger drone detection but has limitations in pinpointing smaller UAVs. The integration of HARK is expected to improve the detection of first-person view drones in challenging environments, potentially closing border protection gaps for NATO states. The outcome of these tests may influence future acoustic sensor deployments in military operations.
