C-57-D was a starship that was registered for Federation travel in the late 24th century.
In 2370, the captain of this ship was J.J. Adams. The starship's point of departure was Lunar Receiving. The starship arrived at Deep Space 9 on stardate 47562.0. The C-57-D was listed on the space station's arrival roster. (DS9: "Whispers", production art)
This starship was only mentioned in writing.
The ship and its captain were an in-joke reference to the United Planets Cruiser C-57D and its commander John J. Adams from the classic 1956 science fiction movie Forbidden Planet.
