The Calypso was the captain's yacht aboard the USS Enterprise-D. (Star Trek: The Next Generation Technical Manual)
- The Calypso was never seen in use or mentioned in dialog, but its designation comes from the TNG Technical Manual. It was named for Jacques Cousteau's ship Calypso by Patrick Stewart. Production staff wanted to use the yacht in episodes such as TNG: "The Neutral Zone" and "Samaritan Snare," but budget restrictions prohibited building a miniature and sets. The yacht did not become part of Trek canon until the debut of the Enterprise-E's Cousteau in Star Trek: Insurrection.
