The S'Harien-class battlecruisers were a type of starship on active duty in Starfleet beginning in the 2290s and probably continuing on into the early 24th century. (Starfleet Prototypes) The basic design was derived from the Menahga-class battlecruiser. (Starship Design) The prototype was deemed successful during trials but the names of ships other than the lead ship are not known.
