Sagitar

This was an insane, kooky idea by Admirals Hodges and Holmes, who joked about an "Escort Dreadnought" to guard all sizes of Carrier, and lead some Destroyers and Frigates in major assaults on Starbases and Klingon Battleships, and due to the Organians' disappearence in 2278, and the General War, with astly increasing raids by Klingons, Romulans and Lyrans, in all the hubbub, one of these were actually ordered and completed at Antares Fleet Yards in 2281, where it operated with two whole fleets of ships to drive the Klingons back until 2287, and scrapped due to the Utopianists' VAST dislike of Dreadnoughts, Battleships, Battlecruisers and anything overly warlike in 2300.
