Valiant II was authorized with the registry NCC-1731 by the Starfleet appropriation of stardate 4444 to be named as a replacement for the USS Valiant (NCC-1709). The Valiant, commissioned with registry NCC-1718, entered service on reference stardate 2/0010. Valiant was refit to Constitution mark III specifications on stardate 2/0312, and again to Enterprise-subclass specifications on stardate 2/1802. (TOS reference: Star Fleet Technical Manual; FASA RPG module: Federation Ship Recognition Manual)
By the 2280s, Valiant was outfitted to the specifications of a class XI vessel, specifically as a rear-fire heavy cruiser. (FASA RPG module: Federation Ship Recognition Manual; ST video game: Starfleet Command)
