Flagship
From Halopedia, the Halo wiki
A Flagship is a ship that commands operations in a fleet, not a classification of ship. It can be any warship, and is not restricted to any particular classification. This is the ship that houses the Commander of the armada.
Speculation
Though it is speculated that Battlecruisers and Carriers are usually the flagships of a fleet or smaller unit structure.
