His Imperial Majesty's Ship Decimator is one of the largest, and probably the most heavily armed, vessels in the Galaxy. Command centre for the Imperial Navy, the Decimator has highly advanced command and control systems plus the ability to perform complete overhauls of Patrol Ships and emergency repairs to Battlecarriers. As a City Ship the Decimator provides a Member of Parliament as its Captain. By convention this is always the Admiral of the Fleet (currently Augustus Victor).
