The UNSC Hamlet (CVA-43225) was a modified Carrier and served as the central hub and main headquarters for the Alpha-Zulu Corps, an elite grouping of spartan II's and III's made to combat the Covenant in absolute dire situations. The ship was led by Captain James T. Avery and served the UNSC Navy for five years until its destruction in the Battle of New Century in 2545 where it was shot down.
