Flagship

A Flagship is a ship that commands operations in a Fleet, not just a classification of ship and can sometimes even be an orbital platform. It can be any warship and is not restricted to any particular classification. This is the ship that houses the Commander of the Fleet/Armada/Battlegroup.
