A starbase is a facility where starships are maintained and resupplied, and crews can relax. A starbase can be a research station, a military base, a place for interstellar trade or a seat of administration. Some starbases are also involved in the construction of starships.
Hmmm. Actually I am having some problems with accepting this as the canonical Star Trek definiton of starbase. I think that to be fair it needs to be cut down to "A permanent Starfleet Facility". I think there is enough on the show to justify it being used for medical purposes and rendering assistance to starships, but it isn't even clear if that is the 'purpose' of a starbase or a side-effect. The business of it being built for military, research purposes etc. is not confirmed, although it fair to say those things happen on a starbase. 188.8.131.52 05:21, 25 Feb 2005 (GMT)
