USS Mercury
From benscondo.wiki-rpg.com
Currently one-of-a-kind, the USS Mercury is reputed to be the fastest ship in Starfleet and seems oddly small on the inside. Apparently unattached to any fleet or command, the Mercury appears to be the personal ship for Vice-Admiral Nelson, who is ably assisted by Master Chief St. Clair. The ship is commanded by Captain Cletus Jansen.
