Write-Up:

Designed to be part of the Ordenite nuclear triad, and thus a deterrent to those whom the UWO considers to be a threat to their regime, the Type 222 Hammerhai class SSBN carries sixteen R-29RMU2.1 Layner SLBMs, each capable of carrying up to twelve 100 kiloton MIRVs. The submarines are designed to use acoustic and other forms of stealth in order to hide in the oceanic waters until they receive orders to launch their missiles, or need to recrew or replenish their supplies, whichever comes first.

Given the deterrent value of these submarines, they are naturally a high value target for enemies, and must depend upon stealth, counter-detection of enemies, as well as protection from friendly units in order to remain a survivable part of the nuclear triad. The fact that the submarines can fire their missiles from thousands of kilometers away creates large areas in which they can hide, and still be able to fulfill their grim duties.

Construction and Stealth

The hull of the Type 222 is made from 80 HLES steel (12NiCrMoV18), which has a strength of 770 MPa. This is slightly higher than that of HY100 steel, but 80 HLES steel has higher elasticity than does HY100. This elasticity allows for an improved ability to withstand the deformation cycles that occur when the submarine dives to greater depths, which place increased stress and pressure upon the hull. The strength and toughness of the Type 222's hull allows the submarine to dive to depths of four hundred meters, though care must be exercised when at these depths, as the pressure can crush the entire submarine as if it were an empty beer can, killing all aboard. The hull's strength is further increased via ribbing and compartmentalization.

In order to accommodate the submarine's nuclear armament, an addition was made to the hull that looks much like a road ramp, which connects with the aft end of the submarine's sail. This "ramp" was designed to be as hydrodynamic as possible.

In order to increase the submarine's acoustic stealth, a technique known as rafting is employed. Rafting means mounting machinery on steel rafts, and attaching these to noise-absorbent materials that are also attached to the hull, in order to prevent noise and vibrations being transferred to the hull, and from there into the water around the boat. Rafting has been shown to markedly increase the acoustic stealth of submarines that employ it, and have become standard design practice in all modern submarine designs.

Anechoic tiles are another method used to increase the submarine's acoustic stealth. Anechoic tiles are rubber or synthetic polymer tiles containing thousands of tiny voids, applied to the outer hulls of military ships and submarines via adhesive.

Their function is twofold:

1.) To absorb the sound waves of active sonar, reducing and distorting the return signal, thereby reducing its effective range.
2.) To attenuate the sounds emitted from the vessel, typically its engines, to reduce the range at which it can be detected by passive sonar.

The synthetic polymer tiles used on the Type 222 class are 51 mm thick, using multiple layers and different sized voids in order for each layer to be able to target specific acoustic frequencies associated with machinery at that location inside the hull.

A degaussing procedure is used to reduce the magnetic signature of the submarine. A sea-going metal-hulled ship or submarine, by its very nature, develops a magnetic signature as it travels, due to a magneto-mechanical interaction with Earth's magnetic field. This signature can be exploited by magnetic mines, or facilitate the detection of a submarine by ships or aircraft with magnetic anomaly detection (MAD) equipment.

To minimize this magnetic threat, Naval vessels are normally fitted with on-board Closed Loop Degaussing Systems that generate a counter-acting field to reduce their magnetic signature. Such systems typically are comprised of three different systems, integrated into one.

1.) An electrical coil system that generates the counteracting magnetic field
2.) Magnetic Field Sensors that measure the strength of the Earth's magnetic field with respect to the coordinate system of the submarine
3.) A control system (including current amplifiers) that obtains magnetic information from the magnetic field sensors. Based on this information, the control system controls the correct current distribution in the coil system.

Modern on-board Closed Loop Degaussing Systems operate in the vertical, long ship (heading 000), and athwart-ship (heading 090) directions. These systems can reduce the submarine's magnetic signature by as much as 95 percent, significantly reducing the submarine's susceptibility from multiple threats.

The bow planes, which project out to the sides of the hull itself, are used to "fly" the boat through the water. By varying the angle on these planes the boat may be made to rise, fall, or remain at the same depth as it moves forward. Since the boat is normally trimmed to be slightly positively buoyant, the planes are used to hold it down. This is a safety feature, because if all power is lost it is normally preferable to slowly rise to the surface and not to sink.

The submarine uses ballast tanks in order to maintain depth, to rise, or to descend in depth. If these tanks are filled with air, the submarine rises, due to a positive buoyancy. If the tanks are filled with water, then the submarine will dive deeper into the water, as the submarine is thus less buoyant. In order to maintain depth, the ballast tanks must have a carefully balanced amount of both water and air in them, and for this reason, the ballast tanks are computer controlled, though manual controls are also available, in case of battle or other damage.

A specially designed dry-dock shelter for Swimmer Delivery Vehicles can be installed over the submarine's aft escape trunk, allowing the submarine to remain farther offshore while still being able to deliver special forces commandos to and from the beach. The aft escape trunk is also compatible with Submarine Rescue Vehicles, which offers a capability to remove the crew from the submarine if the submarine becomes disabled. Six people can be processed through the aft escape trunk at a time, due to space constraints.

Propulsion

The main propulsion system of the Type 222 is powered by the SNR-2020c Pressurized Water Reactor, which can provide up to 190 Megawatts of power. Unlike previous versions of Ordenite Naval PWRs, the SNR-2020c can use natural circulation at lower power demand levels, thereby making the submarine quieter at slow speeds than previous submarines that have seen service in the Ordenite Kriegsmarine. The steam generated by the SNR-2020c PWR is run through three steam turbines that generate electricity.

Unlike previous submarine designs that relied on a mechanical gear system and shaft to provide power to the main propeller, the Type 222 utilizes an Integrated Electric Propulsion system that uses the electricity generated by the steam turbines to power both the submarine's various systems, as well as the electric motor that turns the submarine's singular propeller at the desired RPM to obtain the desired speed for the submarine. Removing the shaft and associated gearing systems reduces the cost of the submarine by a very significant degree, and also removes one of the most complex mechanical systems onboard, the only exception being the nuclear reactor itself.

Should something compromise the reactor, or cause it to stop working, two diesel generators providing six hundred kilowatts of power have been installed in the submarine in order to provide a means for a slow "get me home" speed, as well as reduced power to the ship's systems. There are also batteries for the submarine's communication systems, allowing the ability to get a message out to higher command in emergency situations. This is in addition to the emergency communications equipment.

Integrated Combat System

If the systems of the submarine are the various limbs and other organs of the boat, then the Seetraum Integrated Combat System is the brain and nervous system, scalable from the smallest SSKs, to the largest SSBNs.

Seetraum ingests data from all of the submarine’s sensor and communication systems to provide a common operational picture. It provides sensor data fusion, target motion analysis, tactical situational awareness, and command decision tools. Seetraum also integrates the tactical control, weapons/payload control, information assurance, and tactical network subsystems, enabling the watch standers and commanding officers to execute their mission from multi-function consoles in the submarine's command center with all of the information that they need at their fingertips. The system also allows the command crew and the various compartments aboard the submarine to send instant messenger or text messages to each other, as their duties require, including to and from the submarine's commanding officer. New functions can be introduced via software as they become available, including those related to hardware that may be refitted into the submarine from time to time.

Communications

The first part of the communications suite of the Type 222 is a Ka-band SATCOM communications system. This allows for communications between higher command and the submarine, no matter where in the world that the submarine is.

Communications Management Software has been installed onboard the submarine, providing economical, efficient, and effective routing of messages across multiple communications frequencies both within and without the submarine. When combined with the submarine's Integrated Combat Management System, the communications management software also allows for instant messenger and text style communications between compartments within the submarine. This feature does not involve sound, and can be used even in ultra-quiet conditions.

A floating wire communications device allows the submarine to receive communications in the 2 MHz to 35 MHz range while the submarine is at depths of up to 125 meters from the surface. Reeling and unreeling of the floating wire can be performed at depths of up to 400 meters. This measure gives the submarine the ability to remain stealthy while receiving important communications, even in enemy patrolled waters.

A series of Digital Modular Radios have been installed in the Type 222, with a frequency range of from 2 MHz to 2 GHz. When combined with the installed communications management software, the Digital Modular Radios provide a single point of control for communications in the maritime HF, VHF, and UHF radio bands. Two crossed loop type antennas are present on the submarine, allowing the communications system to pick up and transmit in the VLF/LF bands.

An ELF receiver has also been installed, allowing for the purchasing nation to be able to contact their submarines while they are at depth. Since ELF transmissions have a very low data rate, these transmissions are generally short, rarely consisting of more than a short alphanumeric code bloc that tells the submarine to reach periscope depth for the reception of further communications using higher data rate radio frequencies. Due to the massive nature of ELF transmitters, they are not able to fit onboard a submarine, though an ELF receiver can.

The Type 222 implements an encrypted underwater telephone. Using high frequency acoustic transmissions, the underwater telephone provides the ability to communicate with other submarines and surface ships without having to come near the surface. Users of this system should be advised that it is possible for nearby enemy units to be able to track the acoustic transmissions, and therefore use of the system should only occur when needed, and once it has been determined that the area is clear of nearby enemy units.

An IFF system has also been installed, which tells friendly units and weapons that the submarine is another friendly unit, and should not be attacked or fired upon. The system is meant to help prevent blue on blue friendly fire situations, as well as helping to improve the tactical picture for all friendly units.

The major difference between Ordenite and any potential export submarines is that the encryption computers aboard will be memory erased, so that the user nation can use their own encryption methods, while Ordenite encryption methods remain secure.

Sensors

The ES-3701U R-ESM receiver is a compact mast-top receiver that can simultaneously tracking up to five hundred transmitters, with a library of up to 20,000 different emitters. The receiver works at frequencies ranging from 2-18 GHz, and has a reaction time of less than a second. It can be programmed to sound an alarm when it detects certain emitters.

COMINT and C-ESM is provided by a small, CO-2034 mast-top receiver that can monitor frequencies ranging from 9 KHz to 6 GHz, and provide direction finding on signals ranging from 300 KHz to 3 GHz. Direction Finding is done via means of Watson-Watt, and Interferometer techniques. The system can be run from a single multi-function console, and can even be used to compile reports on signals of interest, which can be attached to reports to higher command, or even processed while the receiver is not in use, onboard the submarine.

The Type 222 makes use of the Meereswal-N Integrated Sonar System. The system begins with a conformal bow sonar array, taking up the lower half thereof. Though less sensitive than the traditional spherical bow sonar array, this arrangement allows the submarine's torpedo tubes to be placed together in the upper half of the bow, thus simplifying the design of the submarines' torpedo compartment. The conformal bow sonar array is an active/passive array, and is supplemented with a combined mine/ice sonar in the root of the sail, as well as by passive flank sonar arrays, and a towed sonar array. The arrangement gives the Type 222 a full three hundred sixty degrees of sonar coverage. A pair of chemical "sniffers" are also employed, which test the surrounding water for chemical signs that another submarine might be in the area.

Navigation

Navigation is accomplished via a highly accurate ring-laser gyro Inertial Navigation System, with drift error corrected by the occasional Selective Availability Anti-Spoofing Module-enabled GPS reciever fix. The Type 222 also has a compact (the robust, pressure-proof dome containing the radar head measures 650 millimeters by 510 millimeters) X band navigation/surveillance radar (frequencies programmable from 9300-9500 MHz) whose mast does not penetrate the hull. Using a planar array with a maximum rated power of fifty watts and turning at twenty two RPM, the NR-50 radar has a maximum range of sixty six kilometers, but can also reduce radiated power to less than one watt for close-in, Low Probability of Intercept operations, if required. The radar has a capability of up to two hundred Automatic Radar Plotting Aid tracks, and can also show other obstructions, such as shorelines. The radar can be operated at temperatures from -25C to +55C, and can be stored at temperatures from -30C to +70C.

The inputs from these devices are fused with the data from the other sensors, and are presented to the Navigator and Commanding officer on a multi-function display table with full ECDIS functionality. The information is displayed using standardized symbols and terminology, in order to reduce confusion, and allow for proper mission planning. The commanding officer or other officer controlling the submarine while the CO is indisposed can also open windows on the display that can display any information desired that is available to the ship.

Armament

The Type 222 carries eighteen Seelöwe heavyweight torpedoes, which would typically only be used in self-defense, as the Type 222 is not expected to hunt down other submarines or surface ships. Accordingly, the submarine only has four torpedo tubes.

The other armament of the Type 222 is sixteen LinkR-29RMU2.1 Layner SLBMs. These three stage liquid-fueled SLBMs have a maximum range of twelve thousand kilometers, and can carry up to twelve 100 kiloton MIRV warheads. The design for these SLBMs was stolen from Russia by Ordenite Intelligence, giving the UWO a strong head start in their own ballistic missile research programs.

The Layner's liquid fuel is a mix of fifty percent Unsymmetrical dimethylhydrazine, and fifty percent Dinitrogen tetroxide. While the fuel mixture is both hypergolic, and storable for long duration at standard temperatures and pressures, it is extremely toxic, carcinogenic, and corrosive. Expensive and comprehensive special protective measures must be taken at all times with these chemicals, and as a result, the fuel mixture is not nearly as safe as comparable solid-fuels.

Each Layner SLBM is launched from the launch tube via a gas charge, after which the missile rises up past the surface, the two components of the hypergolic fuel mixture combusting on contact with each other, thus starting the rocket motor without further assistance. In order to launch the missiles, the submarine must be at a depth of fifty five meters, and traveling at a speed of no more than seven knots. As with an SSGN, this is potentially the most vulnerable moment in the lifetime of an SSBN, as missile launches are very loud events, and compromises the submarine's acoustic stealth until such time as the submarine can safely extricate itself from the launch point.

Countermeasures

While the best countermeasure for any submarine is to be so stealthy as not to be detected, the Type 222 does have an anti-torpedo decoy system.

The Type 222 is protected from enemy torpedoes by the Seeigel countermeasures suite. The system starts with the torpedo defense computer, which is tied into the submarine's sonar suite and combat management system. Programmed with advanced defensive algorithms, the Seeigel suite can be set to either automatic or semi-automatic (man in the loop) modes.

The Seeigel countermeasures suite also contains torpedo defense simulations, which are a valuable training aid, and can be programmed with the latest defense algorithms should new situations or solutions arise. No decoys are launched during these simulations, but the system otherwise acts as normal.

A typical Seeigel operational sequence would look like the following:

1.) The protected submarine's sonar detects an incoming enemy torpedo
2.) The protected submarine's CMS is alerted
3.) The protected submarine's CMS alerts the Seeigel system
4.) Seeigel's defense programming analyzes the threat
5.) Pre-programmed response (automatic or semi-automatic) is selected
6.) The selected pre-programmed response is executed
7.) Seesirene-S decoys are launched
8.) Seeigel displays suggested course and depth for evasive maneuver

A submarine launched reactive decoy, Seesirene-S is designed to respond to two different types of torpedo simultaneously, whether they are active, passive, or passive homing. Once the appropriate acoustic decoy modes have been activated, the decoy seduces the incoming torpedo into attacking the decoy until the torpedo runs out of fuel or energy.

On receipt of a torpedo alert on board the submarine, Seesirene-S may be launched from its launcher. The decoy is initiated automatically after launch, propelling itself to a preset depth between 10 and 300 meters, where it hovers and listens for the torpedo transmissions. Active acoustic transmissions are detected and analyzed resulting in decoy selectivity and generation of the appropriate deception signal for transmission including Doppler effects, target highlights and target self-noise. If no torpedo transmissions are detected, Seesirene-S incorporates generic responses, which are transmitted to counter passive homing torpedoes. The decoy’s “threat library” can be customized for each user’s particular requirements. At the end of life the decoy sinks, and all software is erased. The Type 222 submarine has sixteen decoys port, and sixteen decoys starboard, providing a total of thirty two Seesirene-S decoys for use against torpedoes.

Crew Facilities

Though submarines typically are not renowned for their creature comforts, the Type 222 attempts to keep the morale of the officers and crew as high as possible in the limited space available. Both the crew and officers mess have televisions with DVD/VHS players, allowing the crew to watch party approved movies in their downtime. A locker-sized library gives the crew the opportunity to read party approved literature during their downtime as well. Board games and other means of entertainment can also be used to maintain morale.

Enlisted ratings are required to "hot bunk," which means that more than one crew member is assigned to a given bunk, and the crew sleeps in shifts. The feeling one has when lying down on an already warm bed gave rise to the term. Officers are assigned three to a cabin, while the XO's cabin has two bunks, and the Captain's cabin has a single bunk. In Ordenite submarine tradition, not even The Leader can displace a submarine's Commanding Officer from their cabin, which led to the XO's cabin having a second bunk for guests. This is less for altruistic reasons, and more to do with the fact that the captain's cabin has special security measures that allow the ship's commanding officer to read classified orders, and any other classified information that may be sent from higher headquarters.

Most of the officers and crew are required to share the submarine's shower and head facilities, but the captain and XO share a small private bathroom, located in-between their cabins. As water is frequently prioritized for other uses, submariners are advised to take very quick showers. Human waste flushed down the heads is held in storage tanks, which can be emptied into the surrounding ocean, as required. The process of emptying the tanks makes noise, so submariners are asked to be cautious about when and where they perform this task.

Biodegradable trash disposal is handled by means of a smaller tube not unlike that used for torpedos. Dry waste is consolidated using a trash compactor and then placed in special cans. These cans are fabricated on board from prepunched galvanized, perforated steel sheets, using a roller tool. The resulting cans are 72.39 centimeters long and 22.86 centimeters in diameter. They have metal tops and bottom caps. Wet waste is disposed of the in the same way, except that a food grade aluminum foil tri-laminate bag is placed inside of each "wet can." The tri-laminate bag ensures that none of the wet waste leaks from the container, and is sealed when full.

Metal weights are added to the interior of the cans, ensuring that the cans will go to the bottom. The cans are ejected from the submarine using a trash disposal unit (TDU), which is a long cylindrical, vertical tube connected to the ocean through a ball valve. Several cans are placed atop one another in the TDU, the top of the TDU is sealed by closing a pressure cap, the ball valve is opened, and the cans ejected through a combination of gravity and air pressure. It should be noted that this procedure can compromise the submarine's acoustic stealth by generating noise.

Trash which does not biodegrade is stored inside of the submarine until it can be off-loaded in port facilities.

Food is provided for both officers and enlisted from the ship's galley, which uses all electric cooking equipment in order to reduce the noise made from preparing food for the crew, and to reduce the chances of accidental explosions. The endurance of the submarine is determined by maintenance and the amount of food stored onboard. The Type 222 can carry enough food for eighty days of operation before the submarine must resupply. Given the demanding nature of submarine duty, and the quality of the officers required, food aboard Ordenite submarines is regarded as the best amongst the deployed forces of the Ordenite Kriegsmarine.

In order to obtain purified water, the Type 222 utilizes Reverse Osmosis technology. Unlike flash evaporation methods, Reverse Osmosis is a water purification process that uses a partially permeable membrane to remove ions, sea salt, unwanted molecules, and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter.

Reverse osmosis can remove many types of dissolved and suspended chemical species as well as biological ones (principally bacteria) from water, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as solvent molecules, i.e., water, H2O) to pass freely. Most of the water thus generated is used mainly for cooling electronic equipment (such as computers and navigation equipment), and for supporting the crew (for example, drinking, cooking and personal hygiene).

There is one washing machine, and one clothes dryer on board the submarine. This is enough for laundry to be conducted on a weekly basis by each of the submarine's operational divisions (command, weapons, sonar, engineering). As always, the operation of these machines produces noise, and can help to compromise acoustic stealth, so care should be taken when operating them, even though like other heavy electronic devices onboard the submarine, the washer and dryer are rafted.

Due to the steady supply of electric power provided by the submarine's nuclear reactor, nuclear submarines can obtain breathable Oxygen via a process called electrolysis. In essence the electrolysis of water splits the Oxygen atom from the two Hydrogen atoms using electric current. The Oxygen is then released into the ship's atmosphere, while the Hydrogen is released back into the surrounding water. Advanced filtration and other processes are used to remove carbon dioxide, viruses, bacteria, and other dangerous substances from the air.

Safety Measures

While no submarine can survive every eventuality, all efforts had been put forward to give the officers and crew of the submarine a fair chance to survive accidents or combat damage, during the Type 222's design phase.

1.) RESUS - The RESUS system is a series of solid-fuel gas generators, which can be used to empty the ballast tanks in an emergency, thus helping the submarine to reach the surface. The solid-fuel propellant for the RESUS system consists of 157 kilograms of Glycidyl-Acido-Polymer and Strontium Nitrate, which generates a gas of 34% Nitrogen, 36% Carbon Di-oxide, and 30% water. While this system can be used at any water depth, it is considered to be especially useful in deep water, where the submarine might otherwise reach crush depth.

2.) Emergency Sonar Beacon - A submarine in distress raises the urgent need for quick detection and salvage. Search and rescue highly depend on efficient systems which alert passing vessels and provide locating signals to rescue units. The use of a low frequency sonar transducer provides very long ranges of detection and a high frequency sonar transducer offers very precise guidance of rescue equipment in the close range. The EBS system uses active sonar pings in both high and low frequencies in order to assist rescuers in locating the stricken submarine more quickly. The system can be activated manually, or automatically by remote water contact switches coupled with water pressure sensors.

3.) SEPIRB - The Submarine Emergency Position Indicating Radio Beacon or SEPIRB, is a radio signaling device used for locating a submarine in distress. The SEPIRB is stored onboard the submarine, and at the time of the emergency retrieved from storage and launched. The submarine may be surfaced or submerged at time of launch.

The SEPIRB surfaces and transmits a digital message to the submarine owner's national satellite network, which obtains the position of the SEPIRB to within 100 yards using an GPS receiver onboard the SEPIRB. The transmitted message contains the current elapsed time since activation and the submarine's Unique Identifier code until a valid location is obtained from GPS (the "initial location"). Once the initial location is obtained from GPS the transmitted message contains the current elapsed time, identifier code, initial location obtained by GPS, and elapsed time associated with the initial location. If no GPS location is obtained and/or transmitted by the Submarine EPIRB then its location (to within approximately 3.2 kilometers) will be determined by standard satellite direction-finding methods.

Six hours after actuation, the SEPIRB begins to transmit a 121.5 MHz beacon which is used both in locating/retrieving the buoy and as a backup to the national satellite system message transmissions. The SEPIRB continues both the message transmissions and beacon until either the batteries are exhausted or until the device is retrieved and manually deactivated.

The 100 centimeter long by 7.6 centimeter diameter SEPIRB unit is constructed of Aluminum, and has a weight of 3.6 kilograms. The SEPIRB unit runs on a LiMnO2 battery, which gives it over forty eight hours of battery life.

4.) IDA-59 rebreather/ISP-60 drysuit

In addition, crew members can use LinkIDA-59 rebreathers with LinkISP-60 drysuits in order to exit via the submarine's aft escape trunk, the conning tower, as well as the torpedo tubes, as long as the submarine is at three hundred meters or shallower. If compressed air bottles are properly installed on the proper location on the suit (or if the suit is manually inflated by the user), then the drysuit will bring the user to the surface at a rate of three meters per second, as well as helping the user to float on the surface. The drysuit and parts of the rebreather are a bright orange color, the easier for rescuers to spot the crew members when they reach the surface. While there has been one recorded instance of a user of the IDA-59/ISP-60 combination reaching the surface from six hundred meters, this is not recommended, as this makes it far more likely for the escaping crewman to experience decompression sickness, otherwise known as "the bends."

Export

While the secretive nature of the Ordenite Government means that the submarine is not known to have been exported, it is known that the unit cost of the Type 222 submarine is 800 million dollars. Prices for DPRs to the Type 222 submarine would need to be negotiated with the Ordenite Government.
