UNSC Alliance

The UNSC Alliance was a United Nations Space Command Frigate.

In 2552, it responded to the distress signal sent by Commander Keyes of the UNSC Iroquois in the Sigma Octanus System and moved to reinforce the Iroquois.

Note: This vessel is mentioned as the Alliance on page 145 of Halo: The Fall of Reach and then called the "Allegiance" on page 154. This is likely an error on the part of the author. See: List of Inconsistancies in Halo.
