Flagship

A flagship is a vessel used by the commanding officer of a group of naval ships, characteristically a flag officer entitled by custom to fly a distinguishing flag. Used more loosely, it is the lead ship in a fleet of vessels, typically the first, largest, fastest, most heavily armed, or best known.

Over the years, the term "flagship" has become a metaphor used in industries such as broadcasting, automobiles, education, technology, airlines, and retail to refer to their highest quality, best known, or most expensive products and locations.^[1]
