Navy Captains typically command a single ship - typically a class larger than a frigate but smaller than a carrier. Navy Captains may also command a battlegroup or a small fleet if they are the senior-most officer present.
Captains are sometimes referred to informally as "Skipper" or "the Old Man."
Relation to Marine, Air Force, and Army Captain
The Marine Corps, Air Force, and Army rank of Captain is ranked three pay grades lower than a Navy Captain. Other than sharing a name and both being officer ranks, the two captain ranks are completely unrelated.
