Interstellar Colony Ship

Colony ships are large, long-range transport vessels.

Description
These ships are designed to carry human colonists and supplies to the other stars Outer Planets or even beyond the Star Systems to settle new moons and planets. As such, they required massive storage areas, which makes them attractive targets for conversion to other purposes, authorized or otherwise.

Examples included the the Grand Pioneer. Most Colony ships sail through space, accelerated via fusion drives, matter-antimatter anihlation reactors and/or the interstellar highways.
