The EM-50 Minehunter class represents the latest technology incoporated into a vessel small enough to manouver effectively yet large enough to operate in the open Ocean with a fleet.
DESIGN
The hull of the EM-50 Class minehunter is built almost entirely of non-magnetic materials and are designed to resist high shock levels. Manoeuvrability is controlled, either manually or automatically, by using the Ship Position Control System (SPCS) developed by Elias Aerospace
Low magnetic materials have also been used elsewhere such as stainless steel, aluminium alloys and copper alloys for fastening and mounting systems. In addition all the electric motors are of low magnetic material content and have compensated stray fields. The machinery spaces comprising the main engine room, auxiliary machinery room and the diesel generator room are located between main watertight bulkheads in the stern. The diesel generator room is located on the main deck in order to minimise noise below the waterline.
The remotely operated mine disposal vehicle (ROV) launch and recovery area is on the afterdeck which is equipped with two cranes. A closed hangar provides storage and maintenance facilities for the ROVs and support facilities for divers, including two rigid inflatable boats fitted with silent outboards and a decompression chamber.
MINE COUNTERMEASURES
The ship has a fully integrated minehunting and mine disposal management system which is able to detect, classify, identify and destroy any type of mine within an operating depth of 300m. The system has the ability to record and save all operating data for future use. The system includes two underwater Remote Control Mine Disposal Vehicles . The vehicle is controlled via a 2300m fibre-optic cable. A lighting system, low light level black and white camera and a colour camera are fitted. The vehicle is also fitted with a high-resolution sonar. The sensor data is transmitted back to the operations control centre on the ship. The main payload is a 100kg mine disposal charge which can be replaced by a manipulator. Wire cutters are used to release moored mines from the column of water above the sea bed. The mine disposal vehicles can be deployed to a depth of 375m.
COUNTERMEASURES
The ship is equipped with two lightweight decoy launchers, the launchers are capable of dispensing infrared decoys and chaff in confusion, distraction and centroid seduction modes of operation.
SENSORS
The sonar system is a variable depth sonar which is deployed from a well in the hull. The sonar is a multifunction system operating in VLF and VHF bands. The type employs five arrays for mine search and classification modes of operation.
PROPULSION
The ship has an advanced propulsion system with very low magnetic and acoustic signatures, each developing 2,500 sustained horsepower. The engines are fitted with degaussing coils.
The propellers are non-magnetic and silent running. The material is mainly stainless steel with bronze/composite blades. The ship also has two bow thrusters for postion holding and port manouvering. The diesel engines provide a maximum speed of 23 knots and the ship's speed is 8 knots on the silent electric drive.
