Well I'm bored, guess I'll upload some pictures of spaceships i made using the game Battleships Forever. There are 3 Factions: Alliance, United Terran Nations and Aliens (Haven't bothered to come up with a name for them).
United Terran Nations
The United Terran Nations is the unified government of the Sol System, It's Military is considered to be one of the greatest in Human History.
Terran Navy Warships tend to be equipped with Close In Weapon Systems (CIWS), Missile Launchers, Blasters, 635mm (25 Inch) and 495mm (19.5 Inch) guns on larger ships.
The Alliance is made up of colonized planets far from the Sol System, It's Military was considered nearly a match for the Terran Navy.
Alliance Warships tend to be equipped with Railguns, Blasters and High Velocity Missile Launchers.
Not much is known about the Aliens, Alien warships tend to be equipped with deadly longrange lasers that can quickly devastate human ships.
