The thrusters have sufficient power to sustain the ship speed at a constant 6 knots.John Kirby having a look at paintings in the Walker before visiting Tate Liverpool. The auxilliary propulsion system consists of three 124kW electro-hydraulic motors driving Riva Calzoni retractable auxiliary propulsion units or thrusters, one forward and two aft. The main propulsion consists of a 1460kW Fincantieri GMT diesel driving one shaft controllable pitch propeller. Navigation radar is the Kelvin Hughes Type 1007 I-band radar. It is to be deployed from the Double Eagle mine disposal vehicle. This active, high-frequency sonar is 3D imaging and determines the range, bearing and elevation of mines. Thales Underwater Systems is developing the Acoustic Mine Imaging (AMI) system for use in turbid waters. The system achieves a detection range greater than 1000m and a classification range greater than 200m. The sonar uses frequencies typically 30 to 100kHz for detection and 300 to 500kHz for classification. In the variable depth mode both frequencies operate simultaneously, the lower frequency covering mid-water to surface depths and the higher frequency covering the seabed. The sonar has dual-frequency search and classification capability. The Type 2093 minehunting sonar from Thales Underwater Systems (formerly Thomson Marconi Sonar) is a variable depth sonar which can be operated in the hull-mounted mode or in variable depth mode. The ship is also fitted with a BAE Systems Australia Prism III ESM system and two ML Aviation SuperBarricade chaff launchers. The ship is also capable of towing the ADI Dyad magnetic acoustic influence sweep. AAG is a water-driven, turbine-powered sweep, which is programmed to emulate the acoustic signatures of specific classes of ships. The ships are being fitted with the new ADI Australian Acoustic Generator (AAG) minesweeping system. The vessels have the ADI Oropesa Double “O” mechanical sweep and can also tow the ADI Mini Dyad influence sweep. The ships are being fitted with the new remotely activated Cormorant Lift Bag which brings mines to the surface for disposal. Clearance divers are carried on board the disposal vehicles and are capable of diving to 90m. The vehicle can be deployed at distances of more than 500m from the ship. The mine disposal charge is detonated via a thin wire link running from the ship. A DAMDIC mine disposal charge from Nordic Defence Systems is slung beneath the vehicle for release in close proximity to the mine. The vehicle’s tether cable contains a fibre-optic link for transmitting command signals from the ship and relaying sensor images for display on the multi-function consoles in the ship’s operations room. The vehicles are electrically powered and are equipped with a search light, closed-circuit low light television camera, and onboard detection and identification sonar. The ships are equipped with two Bofors SUTEC Double Eagle II mine disposal vehicles. Main gun is a DS 30B 30mm gun from MSI Defence Systems, which has a firing rate of 650 rounds/min and ranges of 3km anti-air and 10km anti-surface. This provides the ship with auto-track and auto-hover for effective mine countermeasures operations. Where ship manoeuvring during minehunting operations is being automatically controlled, the system controls the auxiliary propulsion system via the minehunter autopilot. The system allows the management of all mine countermeasures activities, including mission planning, minehunting, mine disposal and post mission analysis.
