Flagship

A flagship is a term referring to the status conferred upon a starship. Typically, a flagship is a starship commanded by a flag officer (an admiral or similar rank). The term also properly applies to the ship of whatever commanding officer is in charge of a grouping of ships. A third, more colloquial usage of the term can mean that the ship in question is considered an "exemplar" of the best capabilities and virtues of the force it represents.
