The USS Odyssey (NCC-75309) was a Galaxy-class starship, serving in the Federation Starfleet during the late 24th and early 25th centuries. The ship was launched on 4 October 2373 as a replacement for the previous Odyssey, which had been lost to the Dominion in 2370. The ship's motto was: We sail together, or we do not sail. Captain Barbara Clairidge assumed command of the Odyssey in 2399, when it was assigned to Starbase 185. After Clairidge's departure several years later, command of the Odyssey was given to Captain Valentine Nym.
