Flagship

A flagship was a status given to a starship considered to be the premier ship of a fleet. Typically, a flagship was a vessel commanded by a flag officer (an admiral or similar rank). The term was also properly applied to the ship of whichever commanding officer was in charge of a grouping of ships. A third, more colloquial usage of the term could mean that the ship in question was considered an "exemplar" of the best capabilities and virtues of the force it represented.
