From Ironclad Press

"Black Water Navies rules are for any Space Ships that you already have. The setting is the Orion Arm during the year 2284.  You are able to pick from 92 nations (humans and aliens), 810 modifiable ship classes. Sizes vary from small shuttle-size crafts to huge battle wagons. The table size can vary from 2-foot square (if you use centimeters) to 4x8 (if feet are used). Included are rules for all aspects of war in space: 3d, mines, ECCM/ECM, subs, armed shuttles, lasers, plasma, asteroids, surface weapons, etc.

Each ship is fought separately. Players can control as many as they wish, usually 2 large to 4 small. There is a point system for those desiring equal battles.

Each ship class can be modified to the player's requirement: armor, weapons, crew level, types of shells, electronics, etc. The aliens have several unique weapon systems. Not all nations and ship classes carry the same equipment. Damage can vary from a simple dent to massive loss of equipment."

The Black Water Universe also includes the games Black Water Armies (microarmor) and Black Water Marines (squad level) and all the games can be connected.
