UNSC Alliance

Summary
UNSC Frigate. In 2552, it responded to the distress signal sent by Commander Keyes of the UNSC 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.

Most fan sites, however, like to assume that the Allegiance and the Alliance are two separate ships.
