About the Rikei

The Rikei-class is a Star Army of Yamatai variant of the SSS's Tansaku-Class. It is intended for deep space exploration for military purposes; including detecting enemy installations, investigating facilities, and disabled ships. There is a stealth (1b) variant available in limited quantity for operating behind enemy lines.


The Second Expeditionary Fleet needed a ship more focused towards science for use in some of their deep reconnaissance missions. Building on the successful Tansaku-Class and making only the necessary changes to militarize the design, they were able to expedite the design process.


Rikei-class science vessels are in traditional Star Army of Yamatai blue with the Star Army Hinomaru and registration on top. They have two nacelles which house the Turbo Aether Plasma Drive and the Continuum Distortion Drives. The two Heavy Dual Anti-Starship Gun Turrets on the forward section are always visible. The other turrets are only visible during combat.
