Phoenix-class colony ship (Earth-5875)

The Phoenix-class colony ship is a class of colony ship developed by the Weyland-Yutani Corporation and used by the Unified Earth Government for the colonization of planets. The ships ferry both colonists and the technology necessary to settle on worlds, such as Atmosphere Processing Plants.

Specifications
The Phoenix-class is 2.5 km long, making it one of the largest UNSC ships in the organization's naval history to lack the official designation of a carrier-class vessel.

The Phoenix-class ships were designed by the Weyland-Yutani Corporation to transport thousands of colonists from Earth, or one of the other Inner Colonies, as well as Atmosphere Processing Plants for terraforming operations. Once the terraforming is completed, the colonists settle the planet. Some occasions would see colony ships being decommissioned to aid in the development of a colony. On Shanxi, the UNSC Qing's fusion reactor was used to power the first settlement, Shenlong and its data processing storage housing the agricultural operations synthetic, Mack was also utilized.

Modifications
Some Phoenixes, like the UNSC Spirit of Fire, were modified for war operations by the UNSC during the First Contact War, being redesignated Phoenix-class support vessels. The refitted ships carry vehicles, troops, and supplies as support for ground forces.
