The Indonesia class are the latest class of nuclear submarines to have been constructed in Yohannes. These submarines have been modularly designed to launch the latest of submarine-launched cruise missiles, such as the Tomahawk, or any existing - OOC: NationStates modern technology - equivalent cruise missiles, such as those designed by Yohannes’ closest allies: Alfegos, Anemos Major, Knootoss, Lamoni, Lyras or the Freethinkers.
The standardised, well-constructed design of the Indonesia class submarines allow them to perform a variety of crucial assignments from the coldest of arctic regional areas, to littoral areas of one's region. Some of their missions include covert cruise missile strike, potential enemy or area surveillance, intelligence and information collection, special warfare, as well as anti-surface ship, submarine and mine warfare.
Concept
The Vampier-class submarine is a very recent nuclear submarine design in the Marine of the Knootian Defence Force. The class is regarded as one of the most advanced submarines of its type in the world, and it complements the more numerous but older Elementen-class submarine in Knootian service. The naming convention is intended to evoke the traditional image of vampires as the silent horrors of the night, striking and bleeding the enemy dry. The first ships to have entered the service are the KDF Nachzehrer, KDF Impundulu, KDF Jenglot and KDF Dhampir.
The class has a procurement cost twice that of the Elementen-class submarines, and three times the operating costs, though this does include the Special Forces components associated with the vessels. Budgetary restrictions mean that they are not considered to be a fully viable replacement for the older nuclear submarines, but are nonetheless becoming a larger presence within the Marine.
The design process was initiated by the first Daatman Administration, as the Knootian government sought to increase its international military capabilities. In particular, the requirements identified the limits of the now obsolescent Zeedier-class, which had traditionally been used to support covert maritime intelligence and special forces operations. The conventionally powered submarines were too small to house the increasingly larger equipment needed to support such operations and lacked range to operate in enemy waters for any length of time.
Around the same time Freethinker Defence Industries completed its takeover of the Heraclitus Group, bringing with it a wealth of naval design experience. Given the tight time scales of the requirement, a proposal was put forward based around the Freestian Vengeful Class SSN, and the final design agreed with the Marine was essentially a shortened, heavily specialised version of the Freethinker submarine.
Compared to the general naval workhorses of the Elementen class, the Vampier submarines are highly specialised and capable boats. The quietness of the more recent class is greatly improved, utilising the new acoustic dampening gel common on FDI designs, along with a new all-electrical pump-jet assembly, rendering the boat almost completely silent. New LIDAR arrays and updated sonar arrays were also fitted to improve the attack capabilities of the craft. It should be remembered that, although the Vampiers are rarely used as such, they remain extremely potent attack craft against naval targets, and can track enemy battle groups and submarines with relative ease whilst remaining almost undetectable themselves.
The most important new capability however, was the ability to transport a platoon strength squad of Special Forces and all their equipment (including even piggy backing mini-subs) covertly into enemy territory. The addition of such facilities has reduced the weapon load out to an extent, but the ability to land troops quickly compensates significantly. The Vampier class do possess a number of Cruise Missile tubes to help support associated land forces.
Vessels of the class are still a very rare sight, due to their limited numbers and the nature of their missions. They are rarely deployed in the large wolf packs of the Marine, instead most often used as single units in covert operations. Occasionally however, a Vampier will act as a long range 'spotter' for the Elementen class submarines, identifying targets and feeding this information back to optimise any potential strike.

Refit (Batch II)
One result of this new power projection ambition was the subsequent modification, and refit of the Vampier class - already co-developed together by Knootoss and RBSG - and the realisation of its replacement: the Indonesia Class. The design that appeared out of the - somewhat harassed (by the Empress) technical chiefs' - blueprint are equipped with eight launch tubes, positioned just ahead of the pressure hull's forward bulkhead, and storage room for 50 anti-ship missiles or torpedoes. The design's machinery are somewhat quieter than that installed in the earlier Elementen and Malaysia class of nuclear submarines, built and arranged to be slightly more compact. The pump jet propulsor are designed to slightly limit cavitation, or the formation of bubbles in the back of the submarine, thus lowering potential noise levels, and while at the same time allowing her still to travel unimpeded at her submerged speed of 35 knots.
Her new Beaufort 7MJ-LA1B pressurised water reactor produced a power output of 34 mW, while the array of electronics and suite include the new HMW-2L command system, a sphere-like, globular receiving arranged sonar array, a linear relaying array swaddled around her bow, the new HMW-31U and HMW-71 towed arrays, as well as other sensors. RBSG advertised that an Indonesia class submarine generate less noise at their tactical speed - the speed at which she can remain undetected while being able to target and track enemy submarine effectively at the same time - of 25 knots, than the predecessor Zeedier class, when laid up beside a pier. This, however, has remained to be proven in practice, and should be treated with caution.
The fourth and final modification from the Vampier class of submarines was launched in 2005, and these were outfitted with additional hull sections, thus lengthening vessels of this particular variant, required for special missions as well as research and development projects. Construction of the Indonesia class of attack submarines relies on a new welding material to join the steel into plates, hull sub sections and considerably sized cylinder-like sections. Their hulls entirely composed of high-pressure HY-100 steel, in contrast with the previous Zeedier class of vessels, which were constructed with that of HY-80 steel.
The Indonesia class are roughly 30 metres longer than the Vampier class, due to the introduction of an additional section or plug block placing, known as the AMMP, which stands for Advanced Multi Mission Platform, allowing the launching and recovery of remotely controlled vehicles and special forces. Submarines of the class also have additional navigating devices placed in front and aft of the boat, permitting the Indonesia class to keep station over selected targets in odd currents. Historically, Commonwealth Navy submarines fitted with the above mentioned devices were assigned to intercept opposing side communications by tapping into underwater cables. Vessels of this class are also equipped with their two main periscopes, mounted in a sail that is constructed stronger specifically for operations under even the presence of surrounding ice cap.
The Wilhelm variant of combat system integrated into submarines of the Indonesia class are reinforced with the latest sensors, data processors, consoles and weapon controls riding the same high capacity fibre optic databus. The consoles can be switched to accommodate various command and control tasks, and the bus can handle up to 1,000 messages per second. The whole system is so complex, that it requires around 5,000 to 7,000 litres of chilled water every ten minutes to cool it. The array of electronics utilised by a submarine of this class can be included and adapted to suit any existing modern naval order of battle and group’s infrastructure, or flexibly used without hassle in its role to support nearby land battles, maximising the lethal potential accommodated by her eight-tube, double deck torpedo room. This enables the vessel to engage more multiple threats than that of the previous Malaysia and Elementen class of submarines, at once.
The Wilhelm II Tactical & Combat Networking is the successor to the previous Wilhelm I. It is an advanced modular and integrated combat management & networking wireless systems (AMCMN-WS). The Wilhelm II incorporate the agglomerated and integrated function of a decision-making simulator, sensor, signal processor, wireless networking detector & integration systems within a robust, time saving, and power efficient systematic structure. The rapid development of an integrated circuit technology available worldwide has seen the innovation of multiple networking & battlespace systems, at a pace unheard of the previous generations. Like the Wilhelm I, the Wilhelm II utilises an advanced and upper tier, agglomeration of sensors, radios and processing systems, at a competitively low cost attributed to the design’s geometry and modularity, in comparison to the majority of its overseas competitors. It effectively connects the virtual world and simultaneously fuses it with that of the physical realm.
The Wilhelm II incorporate the application of four peripheral networks, that of the “entrance”, “main”, “support” and “storage” groups of peripheral networks, a total of four main bodies in simplicity. The “entrance” peripheral networks incorporate the agglomeration of an equilibrium activator, sensing circulatory sub-system, signal receiver, input processor, power source storage sub-system (preferably that of the Xzaerom G Network), data storage, wireless interaction & communication sub-system and finally, that of home pin-pointing features. The “entrance” may also be integrated with multiple foreign systems of the same sophisticated level as that of The Wilhelm II (including the previous Wilhelm I), one marked symbol of its multiple ease of integration characteristics. Its attached systems' personnel has the capacity to communicate, if formally registered and upon validation of the specific user’s account(s), through a localised data display and networking information interfaces (DNII). Non-Wilhelm registered and integrated formations within its vicinity may, as per the associated crew’s discretion, communicate with the main body of resources and central server through the input processor peripheral network mentioned above.
As a result of this characteristic, access of the data storage peripheral network’s information and various other crucial tactical intelligence & processed data acquired from that of the sensing circulatory sub-system’s peripheral network, may be accessed easily and effortlessly. Although the addition of Xzaerom’s G Network & data storage in such a method is recommended, however various other alternative networking interfaces may also be used in conjunction with that of The Wilhelm II.
An Indonesia class of submarine also has twice as many torpedo tubes as a Zeedier class submarine, with her weapon magazine slightly more than 30 per cent larger in size. Just like submarines of the Malaysia class, Indonesia class vessels are capable of supporting elite naval special warfare personnel or forces with provision for operating the Dry Deck Shelter (DDS) - or similar existing removable modules with the specific purpose of allowing easy exit and entrance for divers while she is submerged - and midget submarines designed to provide stealthy submerged transportation for special operations forces from their decks.
Theoretically, a submarine of the Indonesia class can circumnavigate multiple regions of our world without having to surface. Practically, however, her range is limited by the amount of supplies she can hold, and the endurance of her crew. Silent, quick, and certainly very much equipped with advanced sensors, their primary purpose are to be deployed to forward combat areas to search out, and destroy enemy submarines as well as surface ships, as well as attacking land targets if need be. Her Majesty Garnet til Alexandros, Empress of Yohannes, originally envisioned the previous Malaysia class, and the Indonesia class, as a group of designs fully capable of protecting Yohannesian commercial interests around the world, and the results are both classes of submarines projected to successfully serve the Commonwealth Navy for the foreseeable years to come.
