Hokkaido class destroyer

The Hokkaido-class destroyer is a class of East Asian Federation Space Forces starship. It is the third largest class of vessel, behind the Seoul class battleship and ahead of the Soryu class frigate. The Hokkaido class is the mid-size attack ship of the Federation Space Forces, and is generally reserved for deep space patrol around the solar system's edges, or in nearby systems.

Physical Design
The Hokkaido line of destroyers is 514 meters long and approximately 165 meters wide. Its primary section consists of a inverted trapezoidal prism, with a primary cylindrical core spanning the length of the ship. Past the primary section, the cylinder contains the engineering and support sections, and the engine compartment. The command bridge is located on the underside of the primary section at the very leading edge of the ship. Other departments are distributed throughout the ship.

Armament and Defense
The Hokkaido class is equipped with a primary armament consists of a complement of 33 unmanned light drone fighters. Secondary armament is a battery of four 180 millimeter antimatter railguns. It is equipped with regenerative energy shielding, which can be hardened to deflect against certain attacks.

Power and Propulsion
Hokkaido class ships are powered by a single starship-grade fusion reactor, with a power output of 992 MW. It is equipped with a single Fujikawa Displacement Drive, providing rapid travel through space. The fusion reactor's coolant system is powered by liquid nitrogen, and is subject to overheating after performing FDD jumps, requiring venting of the main reactor compartment. Standard with all Federation starships, sublight propulsion is provided by magnetoplasmadynamic thrusters at the rear of the ship.

Crew
The standard crew complement of Hokkaido class ships is 545. There is additional quartering space for 512 non-permanent personnel, such as diplomatic corps members or ground combat troops, if necessary.

Ships of the Line
There are currently eight Hokkaido-class destroyers, and four currently in the construction process, each named after a prefecture of the East Asian Federation on Earth.
