Mizaki-class Ballistic Missile Submarine
The
Mizaki-class were a class of four nuclear powered ballistic missile submarines built for the Altesian navy in the late 850s and early 860s. They were named after Altesian battlecruisers, confirming the importance of their roles in Altesian naval doctrine. Immediately upon commissioning, they would carry out nuclear deterrent patrols off of major Evoshan ports, supplementing the ballistic and cruise missile submarines already in service.
The first Altesian ballistic missile submarines were already in service by 856, but they were diesel-electric boats with limited endurance and a missile count of only two missiles. The cruise missile submarines, with the exception of the two nuclear-powered
Chiyoi-class then under construction, were similarly limited. They also had to surface to fire their missiles leaving them vulnerable to attack. As such, the Altesian navy rushed to design a more capable class of ballistic missile submarine, especially as intelligence reports began to pour in about the construction of an Evoshan nuclear powered ballistic missile submarine.
The resulting submarine would be based on of all things, the
Chiyoi-class. The hull itself was similar, but due to the amidships location of the missile silos, many compartments would be moved forward. Her high deck was a legacy of the
Chiyoi-class and would not be repeated on subsequent classes. Much of her design was similarly traditional, with twin shafts and bow planes instead of fairwater planes. Armament consisted of eight ballistic missiles carried in amidship silos and six torpedo tubes, four fore and two aft. Initially, 28 torpedoes were carried, but four were removed and nuclear torpedoes put in their place in 863. Despite the rushed nature of the class, they proved to be rather successful and had relatively few initial issues. They would pave the way for successive, more powerful, submarine classes carrying more ballistic missiles while Evosha would not commission a submarine with a similar armament until 868.
History
After commissioning and working up, the class would be assigned to the Remoris naval district, patrolling Evosha's Mieri coastline while the cruise missile submarines would be moved to the Ekranon continent to patrol the Kanaric coastline. They would continue their deterrent patrols even as newer submarines entered service, only being pulled from service in 876 due to the Submarine Weapons Limitation Treaty (SWLM). They would be mothballed until the 890s, when they were struck from the naval register and scrapped. The sole exception was
Kyilse, which served as a moored training ship until 913, when she was scrapped.
