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 dramatically cutting procurement and operating costs.

Operational with the Israeli Navy, Elbit Systems’ Seagull USV performed superbly in the Belgian Defence Ministry 2017 North Sea trials and has been participating regularly in international naval exercises conducting Mine Counter Measures and Anti-Submarine Warfare missions.
