The Astraeus-Class Battleship is a starship classification in the UNSC navy. It is by far the most powerful ship in the UNSC fleet. Only two Astraeus-class Battleships were ever built. The UNSC Contingency and the UNSC Field of Hope. Both were left in there births, half constructed, when a Covenant fleet assaulted and glassed the industrial colony where they lay. The two ships survived, a testament to their endurance and power. The UNSC diverted trillions of dollars to finish construction under a new name. That of Astraeus, Titan god of the stars.
