Unmanned surface vessel
Seagull is a multi-role unmanned surface vessel (USV) manufactured by Elbit Systems to meet the maritime warfare mission requirements of the naval forces worldwide.
Unveiled at the Singapore Airshow held in February 2016, the vessel is capable of conducting mine counter-measures (MCM) involving the detection, categorisation, localisation, recognition and neutralisation of seabed, tied up and floating naval mines.
It can also be deployed in anti-submarine warfare (ASW), intelligence, surveillance and reconnaissance (ISR), electronic warfare (EW), maritime security and hydrography missions.
Elbit successfully demonstrated the MCM capabilities of a Seagull USV integrated with Klein 5900 multi-beam mine hunting side scan sonar, during mine countermeasure exercises conducted in the Mediterranean Sea in March 2016.
Seagull is a 12m boat made of aluminium and composite materials. The boat incorporates removable floats and bridge dynamic positioning system, and can be configured according to the customer’s requirements.
The vessel offers a highly autonomous and safe seagoing capability, can operate in sea states up to four and survive sea state seven.
Its features minimise risks to human life and significantly reduce procurement and operating costs.
The Seagull USV is operated from port or mother-ship and can be controlled by a single mission control system (MCS). It can be operated in manned and unmanned modes. The built-in command, control, communications, computers, and intelligence (C4I) capability of the MCS enables the control of two USVs simultaneously. The C4I capabilities further provide the operators with situation awareness of the area of operation.
The highly autonomous MCS supports the integration of modular payloads and also allows the swiping of payloads according to the mission requirements. The operations of the USV are operator-controlled using line of sight and SATCOM data-links.
The Seagull USV carries modular mission payload systems including navigation, sailing and safety suite, electro-optical (EO) / infrared (IR) sensors, side scan sonar or synthetic aperture sonar (SAS), forward looking sonar or multibeam echo sounder, diver detection sonar and dipping sonar.
The vessel can also carry diver’s neutralisation system, remotely-operated vehicle (ROV), as well as electronic support measures (ESM) and electronic counter measures (ECM) systems.
Equipped to perform extensive search missions across vast water volumes, the Seagull USV can launch expendable mine disposal vehicles to clear mines. The maximum payload capacity of the vessel is 2,500kg.
The autonomous navigation system (ANS) aboard the vessel integrates obstacle avoidance system, which meets the international regulations for precluding collisions at sea.
Kraken Sonar was awarded a contract by Elbit Systems to deliver KATFISH (Kraken Active Tow FISH) towed sonar system for the Seagull USV, in February 2016. The KATFISH provides real-time ultra-high resolution seabed imagery and maps for a range of maritime applications.
The Seagull USV is armed with a remote control weapon system mounted with a 12.7mm machine gun. The torpedo launching system aboard the vessel allows the firing of torpedoes against hostile submarines and ensures the protection of naval assets, critical sea areas and high-value assets from submarines. The USV also incorporates a non-lethal weapon system.
The propulsion system integrates two diesel engines, two propellers and a pair of thrusters. The USV has a maximum speed of 60km/h and can continuously operate at sea for more than four days.
