The Sim

The Ambassador-class was designed to be a replacement for the aging fleet of Excelsior-class and Constellation-class vessels which had been in service for over three decades, and to create a true front-line heavy cruiser. Between 2325 and 2360, the Ambassador-class heavy cruisers were the primary capital ships of Starfleet until 2372, when Starfleet stopped production of these ships in favor of the larger, more resilient Galaxy class starships.

Task Force 11 brought the design back into service to address the dwindling fleet numbers following the Dominion War, and in support efforts for the current Klingon-Gorn Conflict.
