History
Near the turn of the century, the first grandiose plans were laid for the commissioning of several large battleships with which Drackonisa was to dominate the seas of the region. However, due to project cost overruns, production issues and lack of perceived threats, the project was eventually downscaled to 3 battleships. Maintenance of such large ships generated many problems for the Navy and for the first two years of their launch, there was hardly enough space in the harbour for them to dock safely. Maintenance was also an issue, with it being the pioneer superscaled vessel commissioned by Drackonisa. The first ship of the line, the Invincible was launched of October 18, 2001 and ran into problems shortly after. Due to the rushed project, several sections of the hull were leaking and its onboard electronics were prone to failure. These problems were only worked out during a modernization project, launched shortly after the commissioning of the third and last vessel, the Sovereign which addressed these issues in 2004.
However, due to its lacklustre intial performance, it marred the history and view of this class of battleship, prompting the Navy to search for better alternatives. This contributed to the 2011 decision to purchase a Lyran Arms longsword supercapital ship to supplant the Invincible's role in the Fleet. With the ship now performing up to its initial envisioned capabilities, the Invincible and her sister ships Sovereign and Viscount now serve as stalwart defenders of Drackonisa and symbols of its naval prowess.
Armament
The Invincible class was built with ship to ship combat and fleet defense in mind, mounting numerous VLS missile tubes along its length. The VLS missile tubes are capable of mounting a variety of cruise missiles, AA missiles and anti ship missiles. Built for versatility in mind, the ship can either be used to provide anti-air coverage for the fleet accompanying it, be designated solely as an anti-ship platform by loading the VLS with anti-ship missiles or going the middle ground by having both.
Armed with a battery of 9 18.1 inch rifled guns mounted on 3 turrets, it is capable of launching guided shells with internal inertial guidance system and GPS to strike at targets up to 100km inland. Utilized for surface bombardments, it's sophisticated fire control systems allow it to land hits on surface targets with great accuracy.
For anti-missile defence, it possesses a large battery of the aster 30 missiles.The fully automated system is highly effective against high-speed threats such as tactical ballistic missiles, cruise missiles, combat aircraft and UCAVs (unmanned combat air vehicles). The Aster 30 has the capability to intercept targets at altitudes from 50m to 20km. Against aircraft targets flying at altitudes above 3km, the maximum range of the Aster 30 is 100km. At aircraft targets with altitudes below 3km, the range of Aster 30 is 50km.
A single 128mm/l55 cannon rounds up its CIWS, capable of launching a variety of rounds at a rapid rate of 30 rounds per minute, modular automatic feeding magazines allow the firing of up to four different and immediately selectable types of ammunition; the magazines can be reloaded while the mount is in operation.
The ammunition manipulator system is available to transport projectiles and propelling charges from the main ammunition store to the feeding magazines, which are automatically reloaded. Ammunition flow is reversible. Rounds can be automatically unloaded from the gun. Digital and Analog interfaces are available for its Combat Management System.
Its ASBM's also allow it further anti-ship capabilities, powerful enough to sink an enemy ship with a single hit from 3,200 km away. Equipped with a multitude of missiles, it can provide both missile fire support as well as gun bombardment for both naval and ground operations. The ships remain the ultimate symbol of Drackonisian naval power. The silos are located on the stern of the vessel.
As a defense against submarines, the ship primarily relies on its escorts for protection. However, it is armed with 30 herring supercavitating torpedoes that can be utilized in an anti-torpedo role, to intercept incoming torpedoes if evasion or deploying decoys is not an option.
Capable of serving as a command and control vessel, it can function as a hub for the LEGION network. It is capable of coordinating fire missions for the fleet and increasing their combat effectiveness overall. This role has now been supplemented by the Tyrant, the latest naval acquisition of a Lyran Arms Longsword supercapital ship.
Target Acquisition
For target acquisition and threat detection, the ship possesses several layers of detection methods. The outermost layer is the vessel's link to a long range phased array warning system(PAWS), enabling detection of targets 5,500 km away.The radar is used primarily to detect and track surface targets and aerial threats such as aircraft, sea-launched and intercontinental ballistic missiles. The system also has a secondary mission of Earth-orbiting satellite detection and tracking. Information received from the PAWS radar systems pertaining to SLBM/ICBM and satellite detection is forwarded to the Drackonisian Armed Forces Space Command's Missile Warning and Space Control Centers. Data is also sent to the main military headquarters in Drackengarde and then disseminated among various military units.
The radar system is capable of detecting and monitoring a great number of targets that would be consistent with an attack. The system must rapidly discriminate between vehicle types, calculating their launch and impact points in addition to the scheduling, data processing and communications requirements. The operation is entirely automatic, requiring people only for monitoring, maintenance and as a final check on the validity of warnings. Three different supercomputers communicating with each other form the heart of the system which relays the information through the LEGION network.
The Intermediate Range Tracking Radar(IRTR) is an AESA characterized by the high density of its radiating power (nearly ten times more than traditional radar), fulfilling the requirements for the detection and tracking of ballistic missiles and aircraft at intermediate range, as well as high mobility required in using the system to back up forces in an operations theater. Effective up to 1000km.
The multi-beam processing, combined with Digital Beam Forming, provides improved performance in terms of detecting targets of small radar cross section in an environment of severe clutter and jamming. The radar is capable of tracking targets even with high clutter environments with sea, rain, discrete objects, birds, chaff or jamming.
The AN/SPQ-10C Short Range Surface Surveillance and Tracking Radar is a track-while-scan fire control radar used with the Gunfire Control system on surface combatants.It also detects sea-skimming missiles at the horizon, even in heavy clutter, while simultaneously providing detection and tracking of surface targets and beacon responses. A high resolution, X-band narrow beam radar that provides both air and surface tracking information to standard plan position indicator (PPI) consoles, the AN/SPQ-9B scans the air and surface space near the horizon over 360 degrees in azimuth at 30 revolutions per minute (RPM). Real-time signal and data processing permit detection, acquisition, and simultaneous tracking of multiple targets. The AN/SPQ-10C provides raw and clear plot (processed) surface video, processed radar air synthetic video, gate video, beacon video synchro signals indicating antenna relative azimuth, Azimuth Reference Pulses (ARP), and Azimuth Change Pulse (ACP). The radar will maintain its capabilities in the presence of clutter from the sea, rain, land, discrete objects, birds, chaff, and jamming.
The AN/SPQ-10C has three modes of operation: air, surface, and beacon. The air and surface modes have a submode for Combat Systems training. The AN/SPQ-10C complements high-altitude surveillance radar in detecting missiles approaching just above the sea surface. The system emits a one-degree beam that, at a range of approximately 100 nautical miles, can detect missiles at altitudes up to 500 feet. Since the beamwidth expands over distance, the maximum altitude will increase at greater ranges.
The radar can provide quick response detection of low-flying high-threat targets. Through this function, the radar automatically detects, tracks, and reports any targets entering the Anti-Ship Missile Defense (ASMD) sector that require a reaction time of less than 30 seconds. The operator can select an ASMD azimuth sector width between five and 360 degrees and a range of up to 20 NMI. The ASMD sector function operates together with the air, surface, and beacon modes.
As an anti-submarine defense measure, the ship is also equipped with the DTS-13 sonar, located near the bow in a sonar bulge. The DTS-13 is a medium-frequency (24 kHz) omni sonar designed for operating in shallow as well as deep water. The narrow beams maintain excellent performance in shallow water, while the operating frequency provides extended detection ranges in deep water. It integrates the hull mounted transducer with a digital transceiver to provide simultaneous active and passive digital signal processing, display processing and computer-aided target detection and tracking using CW or FM modulation.
The tracking and radar systems are all fully hardened against electronic interference as well as hacking, with all data communication systems utilizing heavy encryption to prevent compromise. Due to its access point to the LEGION network, as well as its usual role of being the flagship of the fleet, no expense is spared in ensuring the security of the Invincible's data networks.
Propulsion
Power for propulsion is provided by 4 nuclear fission pressurized water reactors, located within isolated compartments in the ship. The reactors are then utilized to drive the 8 steam turbines, with 2 allocated to each reactor, driving a propellor weighing 45 tonnes and measuring 9meters in diameter. Capable of reaching 30knots, the massive ships are more than able to keep up with the rest of the fleet it was designed to support. Each reactor contains enough fuel for up to 18 years of continued operation, and have a service life of roughly 40 years.
