Part of the San Francisco Fleet Yards, an orbital drydock facility was a Starfleet ship construction and repair facility in Earth orbit in the late 23rd century and was usually paired with an orbital office complex which serviced it. Such facilities were designed to be easily reconfigured to fit the many shapes and sizes of Starfleet vessels.

As portrayed in Star Trek: Phase II (Production Artwork, 1977)

Art director Joseph Jennings and concept illustrator Michael Minor created new designs for an updated U.S.S. Enterprise as well as several orbital space stations and vehicles for the proposed Star Trek: Phase II television series. Brick Price Movie Miniatures was hired to build the miniatures for the series. However, when Paramount announced that it would make a Star Trek feature film instead of a new TV series, the models were deemed not up to feature film standards for the era and were scrapped. The Roddenberry Archive art team has used production art by Minor to show what the orbital drydock facility might have looked like had it been completed.
