This 3,000,000 ton (SM+16), unstreamlined battleship is 2,000 feet long. It was initially designed to replace the CA-103 Venus-Class battleship, the first hyperspace-capable battleship developed by mankind.

With the increasing need to project force and the further development of particle cannons, the necessity of a larger weapons platform arose. The answer was the mammoth Venus-Class battleship, which mounts directed radiation beam turrets capable of ranged in excess of one light-second. This granted the advantage over its predecessor of being able to engage multiple targets simultaneously. In addition to its two main guns, it also sports twenty x-ray laser turrets, thirty missile tubes with a store of 2,500 conventional missiles and 500 nuclear warheads with yields between 25 kilotons and 10 megatons.

While a Neptune's armor – equivalent to 12 feet of hardened steel – is insufficient to stand up against its own weaponry, it's sheer size dwarfs most other ships, whose guns have a hard time penetrating its diamondoid hide. This combined with its sixty x-ray laser point defense autocannon make the CA-107 a truly tough nut to crack.

Like most battleships, the Neptune-class battleship does not include noteworthy hangar space in its design, preferring to allocate precious mass to weaponry, power plants, and armor. Still, it carries a small compliment of five shuttlecraft for use ferrying crewmen and supplies between ships when not at port.

The Neptune's primary role is that of engaging and destroying enemy craft. Its powerful armaments are designed to accomplish this at tremendous range with exceeding celerity. Its secondary role is typically one of blockade, since the threat of destruction often serves as a good deterrent. Still, the CA-107’s slower speed leaves it reliant on faster pursuit craft to chase down anything that escapes its weapon range.

The most famous Neptune-class battleship is the Indefatigable. Not only did it serve as the flagship of the Terran fleet during the Colonial Wars, but its timely arrival at the Battle of Botany Bay gave the Terran forces the reinforcements they needed to turn the tide against the insurrectionists. Other notable ships include the Venus, who battlegroup currently patrols the Old Colonies, and the Mars, who is constantly stationed in Sol to serve as both a protector of Earth and a constant reminder of Earth’s military prowess.

Includes eleven airlocks capable of holding eleven people each, a stealth hull (-10 to Detect), and total life support.

A CA-107 has a total crew compliment of 13,345, with 12,600 of them serving as technicians throughout the ship. The bridge and command crew consists of a captain, executive officer, pilot, co-pilot, chief engineer, chief tactical officer, cargo master, two navigators, two communication operators, six sensor operators, and three gunners. The remaining crew are dispersed among the astronomy lab, hundred-bed sickbay, various offices and many establishments needed to service the crewmen of this spaceborne city of war.
