Starbase 25 was a Starfleet space station in the Dengella System, built in the early 23rd century.
The starbase was cone-shaped and orbited Dengella II.
The starbase hosted a bar called The Roadhouse, a favorite of visiting starship crew members.
A Preserver space buoy had been studied and later stored aboard the starbase.
In 2371 Captain Heaberlin commanded the station.
During the Battle of Psellus, she was placed on high alert and the destroyer Caspian was assigned to her. ("Armistice Part II")
After the battle, the USS Robinson and the USS Los Angeles arrived at the station for repairs. ("Assuming Command")
