The Perun class Nuclear powered Aviation Battleship (BBVN) was a program started by the Belfran Triumvirate as a pipedream in the early 1970s, where the ship originally looked nothing like it currently does.
The HMS Perun was launched some 37 years later and after 10 years of construction. It is the largest vessel ever designed and operated by the three navies of the Triumvirate and is definitely the most expensive and powerful.
The Perun is a mammoth of a vessel and simply the largest ever designed or built in the Belfran Kingdom, and New Hayesalia.
Below the waterline the vessel is equipped with nine thrusters and four Azimuth thrusters to greatly improve its otherwise hampered turning circle. Hidden behind its bulbous bow and subsequently protected from certain types of sea-based damage are two equipment pods that, while also providing housing for a vast SONAR system, helps stabilisation by acting as two extra stabilisation ribs.
Powering this huge mammoth are a system of six propellers that lead to three rudders. The Propellers were specially designed for the Perun and have an added bonus of shielding and specially designed blades to help the vessel emit as low a SONAR image and protect the propellers from damage as possible.
The hull under the waterline is comprised of several-inch thick steel plates, thermal insulation and kevlar over the entirety of the hull that only gets thicker under the bow superstructure.
Above the waterline, and perhaps most interesting of all, is the two massive superstructures that hosts the majority of the Command and Control systems that will be discussed later. Between these two buildings sits a novel feature, a flight deck capable of holding up to 12 fixed wing and Helicopters. The flight deck is helped by a ski-jump ramp that extends out to the starboard side.
At a glance you can spot a wide array of missile silos, tubes and VLS cells scattered throughout the ship. While we shall invest these further later in the Weapon Systems article, it is known that the missile silos are deep enough for a ICBM to fit and indeed successfully launch from and that the VLS cells are compatible with modern canisters.
The same Electromagnetic-absorbing mesh found on the Achilles is also found on the Perun. The superstructures have this mesh built into the walls and doors and the essential systems (Reactors, reactor control systems along the pipes and the engine control stations) are also protected by such measures. While the mesh won't absorb all of an Electromagnetic pulses energy, it will allow up to 45% of ship-wide functions to remain after a severe strike. While this would allow the vessel the ability to maintain control of its propulsion and navigation systems it would likely not be combat functional.
The Perun, much like other ships of the Triumvirates lineup either use specially designed systems or modified existing ones in order to achieve the best results capable so that they might have increased survivability in battle.
The class uses a modified version of SEWACO (SEnsor, Weapon control and COmmand system) which is used with the vessels weaponry and CIWS defence systems to improve the way they work together in both protecting the ship and assigning targets and routes for weapon systems so the Perun may be as combat capable as possible. Input for the SEWACO system is achieved through primary or secondary weapon decks on both Superstructures with the MFC consoles.
The superstructures both share an Integrated Bridge and Navigation System (IBNS) seen on other ships in the Triumvirates lineup. The IBNS consists of multi-function consoles capable of displaying functions such as Sensor references, electrical chart display and information systems (or ECDIS) as well as their designated purpose. Should a console be damaged, a neighbouring console can access that ones functions and preform them to a limited degree until a new console can be fitted. Each ship usually carries five to ten spare consoles that are assembled over the hardpoint. Further augmenting the IBNS system is that each of the Superstructures command decks are open designed, meaning that the command decks are essentially one large room with modular panelling to separate sections for privacy or noise reduction. This integrated system is host to an integrated navigation system that encompasses the steering and control equipment ring-laser based Marine Inertial Navigation System (MINS), two data distribution units and a complete set of navigational sensors and meteorlogical equipment. This deck, and the decks below, are linked with a redundant Ethernet system that interconnects the multi-function consoles and sensors for internal use.
Communications aboard the Perun class is coupled with high capacity digital communication switchboards, which interconnects the voice and data communication channels providing a decent level of international communications from room-to-room to an open conference line for ship-wide broadcasts. External communications takes the form of various radio, short-wave channels and land-based networks. Standard packages include Link 11, Link 16, Link 22, Joint Tactical Information Distribution Systems (JTIDS) and JSAT tactical data links, allowing interoperability through both the fleet a Perun is with and any allied forces in the area.
Internet and Intranet ports are available in each of the crewquarters and other relaxation areas as well as the command superstructures and operate separately to the closed-circuit consoles to ensure the onboard system is not compromised by an internet connection. Usually the default connection is rated at 35-40 mbps download although it is prone to dropping to roughly 10-15 mbps in bad weather or when the internet dish is damaged.
The Perun takes the open designed MFCs from the Achilles, ensuring complete compatibility between consoles in case one is damaged or broken by any means. Data lines between each console and the ships systems are shielded and armored with in-built rerouting devices to circumnavigate any broken lines. In the event that either superstructure is destroyed all command functions can be routed to the surviving superstructure or, if both are taken out of action, rerouted to the systems on-site consoles. Such as MFCs in the engine room or the weapon masters room toward the bow of the ship.
The ships were designed to be able to act as command vessels, because of this they are equipped with a fully functioning AN/SPQ-32 Electronic Warfare Suite augmented with the Administratum-originating RHEA Tactical Networking System. The RHEA uses Cloud computing concepts to pool the resources between friendly vessels when engaging the enemy. This allows multiple friendly vessels to operate as a single entity in the identification and destruction of inbound enemy ordnance. A single Perun is capable of tracking 2,560 aerial targets, but with RHEA a fleet of ten Peruns can pool their resources to track 25,600 targets at once. This would remove a threat of a single Perun being overwhelmed by missile salvos from other vessels such as the Lyran Longsword and allows them to reply as a single entity. This is, of course, presuming that the aforementioned Longsword is on its own or without the ability to use the Cromwell II system so highly regarded. RHEA also transmits this data between the vessels coupled with a geographical map and 80-90% accurate locations of the enemy targets in a 2D or 3D format.
Information gathered from the RHEA defence network is compacted and sent to other RHEA units aboard friendly vessels where it merges with the imagery developed from that particular vessel. Any inconsistencies are scrubbed and any new information is beamed back to the first vessel for its imagery to update. This collaboration between vessels benefited smaller ships with the same detection range as much larger vessels it would most likely be escorting and allowed flagships or command vessels an improved ability to command its group in action.
Automated Damage Control System (ADCS) was originally designed for use aboard the Achilles class carrier, but when the Perun started to become a reality the system was overhauled for use aboard the gargantuan battleship. It mixes with the ship-wide array of cameras, sensors, air-and-watertight doors to help contain any flooding or fire aboard.
In the event of a fire, the Perun is equipped with foam sprays in each compartment to aid in putting most kinds of fire out while the bulkheads seal to prevent the fire spreading. Since the Perun itself carries eight nuclear reactors and is capable of carrying nuclear armaments, it is not unthinkable that a scenario may occur where radiation begins to leak. In this event, much like aboard the Achilles, each compartment is capable of being separated by its bulkhead doors which are also lined with lead and each compartment has an improved version of the CO2 scrubbers found aboard the Achilles, ensuring that each compartment could survive for at least 46 hours with as many as 24 people inside without needing to replenish their oxygen source.
Propulsion of the Perun is achieved through eight NN-42 Nuclear Reactors and six steam turbines that separately link to each of the ships six propeller shafts. Each shaft is capable of generating 188,308.167 HP each to result in a combined 1,129,849 HP to propel the ship to speeds of 31.5 knots.
The eight reactors sit in two-reactor complexes to reduce the size and independently produce 143.81 MW each to a total of 1,150.5 MW combined. 842.52 MW of this is used when the ship is attaining a speed of 31.5 knots, leaving 307.98 MW for electrical duties or for powering off-ship equipment if required. Controls for the propulsion systems can be accessed from either the Engine room of the bow Superstructure through the usage of the Multi Function Controls (MFC) and keycodes.
The Perun is equipped with three rudders and five azimuth thrusters to aid in turning and manoeuvring. The propeller blades are housed to prevent or reduce the SONAR images and hydrographic readings from the propellers cutting in the water to a minimum. Arctic or cold-water protection was incorporated with treatments below the waterline and a thicker hull and stronger shafts and rudders help against ice blockages or damage against ice formations. It should be noted, however, that the Perun is not equipped with an icecutting bow and requires an Icecutter to lead it through any formations.
Each Perun makes use of the Theia AESA system, based on the AN/SPY-3 X-Band system, visible on both Superstructures, for advanced detection of both naval and airborne threats through its wide-band Radar system and a array of alternative frequencies and elevation. Theisa is an Active Electronically Scanned Array that is positioned on multiple sides of both superstructures and works much like the COBRA DANE system in the United States. By its very nature the Theia AESA system is highly resistant to jamming systems and by the nature of being AESA allows it to retain some levels of stealth while active. Other radar systems for search methods involve the AN/SPS-49(V)5 and the AN/SPS-48E which is a 2-d and 3-d air search radar respectively. The class also makes use of the AN/SQQ-89(V)3 Sonar suite, consisting of the AN/SQS-53B/C/D active sonar, the AN/SQR-19 TACTAS Passive sonar and the AN/SQQ-28 light airborne multi-purpose system.
Apart from the Theia the Perun is equipped with AN/SPY-3 multi-function radar systems for primary horizon search and precision tracking of enemy aircraft. Airspace control is attained through the usage of modified Mk. 2 type 7087 Air Search radars and an updated version of the AN/SPQ-9B for target acquisition for both the ship-to-ship ordnance and as a guidance system for the CIWS mounted AA missiles should the CIWS' own guidance system fail. As the Perun has a flightdeck, it makes use of the AN/SPN-41, SPN/43C and the SPN/46 for air traffic control and landing aid.
The Perun is equipped with a wide variety of equipment to ensure it can take on a superior combat role in either ship-to-ship combat, bombardment or air defence and denial.
With over 840 VLS Cells spread over 105 launchers, the Perun is capable of launching Tomahawks, ESSM, RIM-161, the vertical-launch ASROC or other missile systems capable of fitting inside a cell in quick succession. It has over 245 SAM Launcher units spread throughout the ship and a series of eight torpedo tubes with four per side that are capable of launching a wide variety of torpedo-based systems. Due to the limited size available reloading would require the presence of a resupply ship. To the fore and aft of both Superstructures sits 56 missile silos. These silos can fit anything from a R-36 (SS-18) to heavy vertical-launch ship-to-ship missiles that, if they arent wide and long enough, uses a plug system that would be fitted in port and a box system to fit inside that plug. While an integral crane/sling system allows for the reloading of individual VLS cells within the plug at sea, the plug itself cannot be removed without the assistance of a rather substantial crane under stable sea-conditions. In practice, this generally limits the removal and emplacement of the plug to port-side rearming intervals.
The R-36s used aboard the Perun have their own flexibility of carrying their MIRV payloads into Low Earth Orbit (LEO) with the Fractional Orbit Bombardment System or FOBS. These ICBMs can also have their warheads swapped out for a small Recon satellite (these variants are often referred to as the Pelican for their mythic role). This would mean in a practical sense a Perun could carry an incredibly wide berth of armaments inside its Silos from anti-ship-ballistic missiles to small-scale reconnaissance satellite launchers with no real way of telling until they launch. The New Hayesalian Military does not employ weapons of mass destruction.
Surface-to-Air defence of the Perun is further delivered via 28 dedicated RIM-174 launchers capable of firing eight missiles per launcher, delivering a total of 224 air defence missiles. These missiles are stored in an eight-round cylindrical launcher, with the launcher holding one missile in readiness at any time. After the initial ready missile has been fired, the cylinder will rotate akin to a revolver cylinder to bring the next missile into readiness. Also providing Air defence are the ships thirteen CIWS mounts using the Millenium Gun system.
The well deck of the Perun Class is capable of supporting two Ship to Shore Connectors. The vessel is equipped to embark a force of 400 New Hayesalian Marines with up to 45 Javelin sized vehicles. While not equipped to directly undertake amphibious landings, the vessel is superbly equipped for low intensity operations and in support of other forces.
The Perun is also equipped with 17 Udav-1 Anti-submarine systems spread throughout the ship. The rocket system, while theoretically capable of engaging nearby Submarines, is intended to provide a multi layer defense against torpedoes and frogmen. Each system has a total of 60 missiles, including reloads, resulting in 1020 anti-submarine and torepdo kill weapons aboard each Perun. Given that these mammoths rarely travel alone this would be bolstered by its fleets ASW weaponry. Each Udav-1 system consists of an ammuntion loading device, firing controls and ground support for crew manning each of the weapon systems. Hardlinks between the launchers and both the fore and aft Superstructures exist so they may be controlled from safety. In addition, the Udav-1 consists of the following;
