Shinryu Class SSBN:

Born in a time of major realignment of Koko's military policies, the ominously named Shinryu (abyssal dragon), namesake of a class of five, was the first Kokoan SSBN, and first nuclear-powered submarine as well.
Given its novel nature, Kokoan designers recieved some assistance from the United States Navy during its development, with some components imported from the US or built under license. The submarine was built around its S1N pressurized water reactor -a developement of the US S5W designed by Nijima industries- and twelve missile silos for as many Poseidon SLBMs. Laid down in 1975 at Kumoi Shipbuilding Industries (former Kumoi Arsenal) she was launched in 1980 and commissioned in 1982, recieving an upgrade from Poseidon to Trident-I missiles in 1988.
After an uneventful career (a positive for an SSBN) Shinryuu reached the time for her mid-life refuel and overhaul in the late 90s, but ultimately got none. Due to post-cold war budget cuts she was decommissioned in 1999 and entered her recyle and disposal phase in 2007.
