The EM-240 Leviathan class Nuclear attack submarine was designed in order to compliment Akula and Sierra class submarines in service with the Elias. The type is highly advanced and little expense has been spared developing it, with innovative design ideas being taken from the West and the East. This is the first submarine the Elias Marine Corporation has developed and once again the company has lived up to its reputation, reliability, ingenuity and capability.
Design
The submarine’s hull is built from a Titanium alloy which while being expensive gives the vessel an impressive diving depth of 2,600ft and as it is light allows a maximum diving speed of nearly 40 knots. The other advantage is that Titanium is non magnetic and MAD gear is therefore useless in detecting the submarine. Power for Leviathan class is provided by a Pressure Water reactor developed by the Elias Atomic Energy Corporation that features excellent levels of radiation shielding and safety systems that have been exhaustively tested.. Instead of standard propellers the Leviathan uses a pump jet propulsors that offers incredible advantages in acoustic stealth over conventional configurations as well as increased reliability. In order to maximise acoustic stealth the hull is covered with sound insulating anechoic tiles which prevents nearly all interior sounds from escaping.
One of the most easily detectable signs of submarines has always been the periscope that can show up easily on surface search radars but on the Leviathan the fibre optic is non hull penetrating and is covered in a RAM coating that makes a small radar cross section into a virtually non existent one. Additionally the periscope’s shape minimises visible wake on the surface. All other antennae and aerials that need to protrude above the surface at some stage all have these stealth features to minimise the risk of detection.
The submarine was designed with the object of having the least crew possible and using automated systems and eliminating certain jobs through technology the compliment of the class need only be 112 although spare accommodation for 36 is provided for missions such as Special Forces Insertion where additional personnel are required.
Weapons
The Leviathan class boats excellent war fighting capability and an emphasis has been placed on land attack as well as anti-surface/anti-submarine warfare. The Torpedo room is located one compartment aft of the bow behind the huge active/passive sonar sphere and has 4 533mm torpedo tubes and four 650mm torpedo tubes (The four larger tubes can be reduced to 533mmdiamterusing tube liners). These different sizes mean that the submarine can fire a whole range of torpedoes, mines and missiles such as the SS-N-21, SS-N-16, Skhval, EAW-22 Cruise missile (http://www.nationstates.net/forum/viewtopic.php?t=79705&highlight=) and Yakhont-3 Anti ship missile (http://www.nationstates.net/forum/viewtopic.php?t=79445&highlight=). The torpedo compartment itself can store a total of 38 weapons.
The Leviathan in addition also has 16 650mm Vertical Launch tubes mounted in a 4x4 layout just forward of the sail which are able to fire nearly all existing anti-ship and land attack missiles that can be fired while submerged.
