In a Sea Acceptance Test (SAT) performed by the Israeli Navy, a Helicopter Long-Range Active Sonar (HELRAS) dipping sonar was successfully converted for operation onboard the Seagull, Elbit Systems’ Unmanned Surface Vessel (USV).

Operating a dipping sonar onboard a USV significantly increases the operational working time and substantially enhances that detection capabilities and the effectiveness of Anti-Submarine Warfare (ASW).

The Seagull autonomous multi-mission USV features switchable, modular mission payload suites and can perform, in addition to ASW, Mine Countermeasure missions (MCM), Electronic Warfare (EW), Maritime Security (MS), Hydrography and other missions using the same vessel, mission control system and data links. Seagull offers navies a true force multiplier delivering enhanced performance to naval operations, reducing risk to human life and cutting procurement and operating costs.
