Space wheels

Space wheels are wheel-shaped Spaceships that are between Imperial-class Star Cruisers on the one hand and Bird-of-prey-class ships on the other in terms of physical size. They have a main hull shaped like a sphere, oval, or cone at the center, a ring-like structure on the outer fringe, and several tubes or pylons connecting the main hull and outer ring. There is one nuclear-thrust engine on the inner hull or several nuclear-thrust engines on the tubes/pylons or outer rings. Space wheels usually are capable of using Jumpgates and can carry smaller ships on the outer ring. They are mostly for civilian use but are sometimes military vessels. These type of ships are mostly used by the Earth Alliance, the Russo-American Mercantile (RAM), the Ferengi Alliance, and Hutt Space and to a lesser extent by Neosapiens.
