Imperial Carrier Battlegroup

Two Mars Class Battlecruisers and an Emperor Class Battleship.
Emperor Class Battleship is a good fleet support vessel, though not bristling with firepower as a certain other strike carrier of its size. It has just few macrocannons, but also has four launch bays and a huge detection range.
Mars class have only two launch bays each, but have a bit more direct firepower - two lance turrets and two macrobatteries. Another selling point is the prow-mounted Nova Cannon.
