LOKI is a maintenance-free expendable torpedo countermeasure designed as a defence mechanism against acoustic-homing torpedoes. It is one of a unique family of high performance, underwater countermeasures that provide a layered defence capability for both surface ships and submarines.
LOKI is capable of operating in two modes: a jammer mode permits the transmission of high-power pseudo random noise and a confuser mode counters the threat of active, narrow band sonar weapons. LOKI is fully programmable and offers the benefits of threat-specific signal input via the external data port as well as the capability for future upgrading without recourse to the original equipment manufacturer.
As a mortar-launched device LOKI is fully compatible with all 130mm Mk36 launcher variants. LOKI can also be configured with rocket and pneumatic launch modules.
