The Throm class cruiser is a class of cruiser designed, built, and in service with the Grand Navy of Velikoslavia. They are classified as guided missile cruisers in Velikoslav navy service but are often referred to as battlecruisers by defense analysts due to their primary role of long range missile strikes and escort duties for the Majestic class battleship. Initially conceived in 1976 to escort the planned class of Velikslav supercarriers that Nicholas I instructed the navy to pursue, they were repurposed in 1982 when the carrier program was formally cancelled by Nicholas II and the design was revised to allow them to serve as flagships and primary strike vessels on missions. When the Splendor entered service in 2020 as the Velikoslav flagship, a plan to refit and refurbish the Throm class was put forward to be completed between 2020 and 2025 and equip the vessels with the new MP6 Radar complex. The last remaining ship is currently being refurbished at Fortuna Ironworks. In March of 2024, it was announced that all ships in the Velikoslav navy would undergo a light refit and combat load out adjustment to provide more weaponry to combat drones.
History
The Throm class was conceived in 1976 under the Cruiser XX Initiative that Nicholas I initiated to escort his Carrier XX Initiative, which was designed to create a nuclear powered supercarrier for the Grand Velikoslav Navy. The initial design proposed by the Imperial Shipwrights Guild called for two lead-cooled fast reactors for the primary propulsion with a heavy emphasis on supporting nuclear carriers against surface and submerged threats and a significant complement of the new Dracal VLS. A design study was conducted throughout 1977 and 1978 and the Central Procurement Board received budgetary approval from the Synod Naval Committee to allocate procurements funds from 1980 to 1982 to build the first vessel. These were to coincide with the construction of the first Carrier XX that was to be commissioned by 1985.
When Nicholas I died in 1980, his great-nephew Nicholas II ascended the throne, om the advice of several more sensible voices in the Synod, he ordered a reassessment of the naval budget with the procurement plan for the 1980s, which highlighted that Velikoslavia did not have good use for a large aircraft carrier. There were no real foreign threats that required projection of power and an aging fleet of surface vessels left over from the Great Republican War and older, many of which were woefully dated. It was determined that these were needed to enforce local control over the Nordic Sea and other key corridors more than project power and the Carrier XX Initiative was cancelled in 1980 with the keel of the new carrier quickly scrapped. As a result of changing priorities, the Cruiser XX Initiative was repurposed and the Imperial Shipwrights Guild was commissioned to redesign the new cruiser class.
A new design was presented in June of 1987 and approved by the Board for the 1988 fiscal budget year. The first keel was technically laid down in 1988 but construction was halted once it was determined that the propulsion pack would not be available until 1990 at the earliest. As a result, the CPB restructured the proposed budgetary timeline and construction began officially in 1990 with the first vessel launched in 1993. In order to spread out the costs, the ships were constructed between 1990 and 2000 with the final vessel entering commission in 2000.
In 2020, it was announced that the vessels would undergo a refit process, modernizing the sensor systems with the installation of the MP6 Radar Complex, which would allow the Velikoslav surface fleet to operate under the new Midas Battlefield Networking System, which represented a major upgrade to the Ravelin Fleet Defense System.
Design and development
Though initial changes to the design were minute, the Central Procurement Board rejected the new design submitted in 1982, citing that the nuclear propulsion system was deemed unnecessary once Nicholas II outlined the new direction that the navy would take. The design was also over 300 meters long which was deeemd far too expensive and material intensive to maintain and construct overtime. The Shipwright made the decision to partially redesign the vessel, proposing a new CODAG propulsion system that was under development at DSU.
Construction
Initially promised to be ready by 1990, problems with the new main drive engines, which used advanced technologies, caused delays and DSU and the CPB made the decision to utilize two older designs provided by Pantra Industries Limited while keeping their own diesel generators, gas turbine, and gearboxes in order to keep the construction schedule.
