The Svila-class is a diesel-electric hunter-killer submarine developed by Ratoskal PR, in service with the Novenad Defensive Navy. The design features both diesel and quiet air-independent propulsion (AIP) using hydrogen fuel cells. When using AIP, the Svila-class can stay submerged for up to a month.
Development
Development of the Svila-class began in 2187 when Novenad Central Command began looking to purchase an attack submarine to control strategic locations in the Minor Baskay, specifically the area around East Hook Island. Ratoskal PR submitted a design in a sparse competition with other proposals, and 6 were commissioned in march of 2185. Design work began less than a month later, and took 8 years to complete. The first four years included much of the groundwork for the vessel, including the design of the propulsion system and general structures.
However, much of the work had to be scrapped in 2191 when Central Command issued a new design requirement, the implementation of VLS cells and an omnidirectional radar system to defend against air and surface threats. This decision was made in light of the recent formation of the Pan-Veiidic Commonwealth (PVC) and the expectation that the Svila-class would undertake strategic operations alongside PVC naval forces. The additional requirement added an additional 4 years to the design phase, but enables the submarine to covertly escort valuable assets and act as a radar picket as part of the Pan-Veiidic Expeditionary Forces.
Design
The Svila-class features a dual mode Diesel/AIP turbine designed by Ratoskal PR, based in part off the diesel turbines in use on the Skimer-class frigates and the electric rotors on the VT122 S/VTOL transport. The turbine drives two counterrotating propellers inside a shroud, which reduces cavitation and increases efficiency. The top speed of the Svila-class has not been released, but has been estimated at about 42 knots surfaced, given the initial design requirement of being able to complement the surface fleet of Skimer-class frigates.
The weapons system of the Svila-class includes 8 VLS cells capable of launching RIM-162 surface-to-surface or surface-to-air missiles, for intercepting aircraft, missiles, and small surface craft. 6 533mm torpedo tubes in the bow can fire passive or active homing torpedoes, and a refit for the UGM-84 anti-ship missile has been considered.
