Developed by Blood Dragons on the basis of Dragon, Blood Dragon is the best heavy fighter class ship availabe in Sirius. Maneuverability, improved power supply and heavy armor make Blood Dragon a deadly weapon in the hands of a skilled pilot. However, Dragons conceal the design of this ship even from their pirate brethren, so the only place where it's built is Kyoto base.
