The Colonial Navy was the Military arm of the Earth Empire and supported by it's fleets of millions of ships, helped ferry supplies back to Earth.

After the Sol Warp hole closure, the Colonial Navy was one of the factions battling for supremacy of Sol, but eventually won control under the leadership of Kron and reopened the Sol Warp Hole to Alpha Centuari, and to reunite the Human Race under his control.

Initial Navy operations included the protection of their supply ships from Tribe raiders and later the mining of power crystals within the Sol System for use as energy cells.

The Colonial Navy in its' prime had been a powerful force, consisting of millions of starships of an technologically advanced, intimidating saucer design, but following it's reformation, the Navy was an echo of what it once was, consisting of sleek, fast ships with rotating sections, presumably to save energy and resources.
