Starbase 173

Starbase 173 was a Federation Starfleet starbase with a space station facility.

Built in 2365, it was commanded by Vice Admiral Mamoru Nakamura, and Captain Phillipa Louvois served as Judge Advocate General.

The USS Enterprise-D visited Starbase 173 shortly after its completion for crew transfers. Among those transfering aboard were Ensigns Sonya Gomez and Dennis Russell, while Ensign Phylo of the Enterprise transferred to the starbase.

A hearing was held aboard Starbase 173 in 2365, at the prompting of Commander Bruce Maddox, to determine the legal status of Lieutenant Commander Data. Ultimately, Captain Louvois agreed with Captain Jean-Luc Picard that Data would be assumed a sentient being.

In the 24th century, Starbase 173 was active in the late 2370s, after the Dominion War.
