The EM-160 'Walrus' is a newly designed Landing Platform dock designed to supercede the EM-155 Amphibious Landing Ship (http://www.nationstates.net/forum/viewtopic.php?t=74553&highlight=) which has failed to meet requirements and is now too small for the newly restructred Marine Expeditionary units. The new vessel offers much lower radar-siganture, better payload and higher levels of crew comfort and survivability.
The primary mission is Amphibious Warfare. An amphibious operation is an attack launched from the sea by naval and landing forces embarked in helicopters, landing craft, and amphibious vehicles on a hostile shore. Thus, the EM-160 must be able to embark, transport, and land elements of a landing force in an assault by helicopters, landing craft, amphibious vehicles, and by a combination of these methods. The combat power of this ship is its embarked Marines and their equipment.
The ship is highly capable and features modern defence systems such as the Shtil SAM system and CIWS mounts. The ship is designed to be extremely flexible as it can be used in either the amphibious role, the helicopter assault role or as a light aircraft carrier.
The Walrus class design integrates the latest in command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) capability. These capabilities are further enhanced by additional, dedicated intelligence, mission planning, and command and control spaces. The shipboard wide area network (SWAN) is a fiber optic shipwide large area computer system. The SWAN will support everything from combat systems to ship systems to command and control nodes to an integrated training system. This network also provides e-mail and internet access capability.
Enhanced survivability features include improved fragmentation and nuclear blast protection and shock-hardened structure. Automation and integration of systems has enabled a significant reduction in crew, projected to be 361. The ship provides three vehicle decks of 25,402ft² and two cargo holds with 25,548ft³ for bulk cargo and ammunition magazines in addition to 1,234m³ for cargo fuel.
Accommodation is provided for two LCAC (Landing Craft Air Cushioned), 700 troops and 18 Advanced Amphibious Assault Vehicles (AAAV) vehicles.
The ship's Advanced Enclosed Mast/Sensor system consists of two large eight-sided structures, which house the radar and communications antennae with a hybrid frequency-selective surface. As well as reducing the ship's radar cross section, the AEM/S system also protects the equipment from exposure to the elements.
