Shelby served as the Trident's captain throughout the Gateways Crisis, the incident with the Beings and throughout the events involving the Selelvians and the Tholian Assembly in in 2376 and 2377. When Shelby was promoted to Admiral and given command of Space Station Bravo, command of the Trident fell to Shelby's first officer, Katerina Mueller. Mueller captained the Trident through several incidents with Selelvian renegades and Orion pirates. The registry number for the ship has only been given in Cold Wars when Arex noted that it was a newly commissioned Galaxy-class starship.
