Starbase 234

Starbase 234 was a Federation Starfleet starbase active in the 24th century near the Romulan and Klingon Empires. The starbase had drydock facilities.

In 2368, both the USS Sutherland (NCC-72015) and USS Tian An Men (NCC-21382) were undergoing repairs at Starbase 234's drydock facilities when they were enlisted to assist the USS Enterprise (NCC-1701-D) interrupt the supply lines between the Romulan Empire and House of Duras during the Klingon Civil War. Fleet Admiral was stationed there at this time. 

In the same year, the Enterprise-D returned to Starbase 234 for a top-secret debriefing on Ambassador Spock's disappearance and reappearance on Romulus.
