The Moray class is a class of nuclear submarine of advanced design that will forms the backbone of New Hayesalia's global reach. Stealthy and deadly, the Moray possesses the capability of a dedicated Vertical Launch System.
The Moray class is a double-hulled design, and is divided into ten water tight compartments. The forward compartments contain crew living spaces, weapons handling spaces and control spaces not critical to recovering propulsion. The aft compartments contain the bulk of the ship's engineering systems, power generation turbines and water making equipment. The reinforced rounded cover of the sail is intended to break through the ice of the Arctic ice cap.
The submarine is fitted with a floating antenna buoy to receive radio messages, target designation data and satellite navigation signals at a great depth and under the ice. The bow horizontal hydroplanes are retracted into the hull. The main mechanisms have modular design and two-cascade shock-absorbing system. The Moray class is also designed for extensive under-ice operations: their diving planes are on the bow rather than on the sail, and they have reinforced sails. The hulls are constructed from HY-100 steel, rather than the weaker HY-80 steel employed in previous classes, to better withstand water pressure at greater depths. The boats also have extensive equipment for shallow-water operations, including a floodable silo capable of simultaneously deploying eight combat swimmers and their equipment. There are two watertight compartments in the Moray class of submarines. For ease of construction and cost savings the new line of NW Canadian Submarines incorporate a number of similar systems. This aids in production, maintenance and keeps costs in line.
These boats are quieter than their predecessors and incorporate a more advanced combat system. For the most part the ship and internal fixtures are constructed of nonmagnetic materials where ever possible, significantly reducing the chances of it being detected by magnetometers or setting off magnetic naval mines. The submarine is equipped with indigenously developed cabin-raft (shock absorbers) system that helped to reduce noise level by over 35dB. The outer side of the submarine's hull, casing and fin is fitted with about 22,000 elastomeric acoustic tiles to reduce the submarine's acoustic signature. The acoustic tiles absorb the sound waves of active sonar, reducing and distorting the return signal, thereby reducing its effective range. The tiles also attenuate the sounds emitted from the vessel, typically its engines, to reduce the range at which it can be detected by passive sonar.
Each boat is powered by a single ultra quiet S6W nuclear reactor, delivering 52,000 hp (39 MW) to a low-noise pump-jet. The Moray makes use of pump-jet propulsors (instead of a traditional propeller), which significantly reduces the risks of cavitations, allowing for quieter and faster operations. The top speed of Moray class submarines is 20 knots (37 km/h) and the strength of the hull gives the Moray a maximum operational depth over 700 m (2,296 ft).
A Fiberoptic local area network is built into the Moray, supporting most of the sensors and fire-control systems, including remote viewing through the periscopes using both low-light television and infrared, an unmanned helm, and direct control of the main motor from the conn. The boat could fight with a team of four in the sonar room and a conn team of eight.
Fire-suppression in unmanned compartments could be initiated remotely, and watch-keeping logs were automatically recorded. In port, the boats can be electronically linked such that one duty watchstander could monitor several submarines. The Combat Management System is an evolved version of the Submarine Command System used on other classes of submarine. The system receives data from the boat's sensors and displays real time imagery on all command consoles. The combat data system is the AN/BYG-1 combat system with a network of some 70 68030 Motorola processors. Weapons control is managed by the Raytheon mk2 fire control system.
The traditional periscopes have been supplanted by two Photonics Masts that house color, high-resolution black and white, and infrared digital cameras atop telescoping arms, as well as Laser range finding. With the removal of the barrel periscopes, the ships’ control room has been moved down one deck and away from the hull’s curvature, affording it more room and an improved layout that provides the commanding officer with enhanced situational awareness.
The submarine's sonar suite is the BQQ 5D with bow-mounted active / passive arrays and wide aperture passive flank arrays. Also fitted are TB-16 surveillance and TB-29 tactical towed arrays, and BQS 24 active sonar for close range detection. The active high-frequency mine detection sonar is the Atlas Elektronik MOA 3070. As the Moray is tasked with under ice operations a great deal of time the BQS 24 close range high frequency active sonar is also used for ice detection, and the Moray is outfitted with MIDAS (Mine and Ice Detection Avoidance) System high frequency active sonar.
The Moray is equipped with TAU 2000 torpedo countermeasures system. The TAU 2000 has four launch containers, each with up to ten discharge tubes equipped with effectors. The effectors are small underwater vehicles, similar in appearance to a torpedo. The effectors are jammers and decoys with hydrophones and acoustic emitters. Multiple effectors are deployed in order to counter torpedoes in re-attack mode. An acoustic interception and countermeasures system, AN/WLY-1, has been developed to provide the submarine with an automatic response against torpedo attack.
The Moray class mounts four forward facing 660mm torpedo tubes and two 324 mm aft facing torpedo tubes. The Moray’s larger 660mm tubes allow for torpedoes to be launched in swim out mode using their own propulsion system which is significantly quieter than conventional water ejection. This reduces the chance of launch detection. The tubes are also capable of conventional water ejection launches.
Currently, the Morays in NW Canadian service are capable of launching the fiber optic-guided DM2A4 Seehecht ("Seahake") heavyweight torpedoes, VA-111 Shkval-2 supercavitating torpedoes(200kt nuclear/Conventional), 650mm Type 65-76 Heavy Torpedo (100km max range), Brahmos cruise missiles and short-range IDAS missiles from its four main torpedo tubes which can function in “Swim out” or conventional water ram expulsion.
The Moray also mounts two 324 mm (12.75 in) torpedo tubes aft facing in its midship. These are loaded with MU90 Impact torpedoes which also have a limited anti-torpedo capability. These can be reloaded conventionally. These hard hitting and accurate torpedoes are a nasty surprise for attackers.
The submarine is equipped with a variety of torpedoes and surface-to-air missiles for self-defence, but the centrepiece of the Moray's weaponry is the 20 vertically launched heavy missiles, located in the central part of the submarine. The New Hayesalian Military does not employ weapons of mass destruction and, as such, the Navy employs submarine launched cruise missiles. The Moray fields seven Tomahawk cruise missiles in each of the twenty tubes, providing 140 missiles in total, with RIM-161 Standard Missile 3's in the additional eight VLS tubes.
