Captain

This article deals with the naval rank. For the rank "captain" in various infantry forces, see captain (infantry).

Captain is the highest line-officer rank used in Earth Starfleet and Federation Starfleet, immediately superior commander. A captain may be a department head or commanding officer of a starship or starbase, an aide-de-camp, executive officer, or adjutant of a flag officer, or a fleet captain.

The commanding officer of a vessel is addressed as "captain" while on their ship, regardless of rank.

This rank is also used in the Imperial Klingon Fleet and the Klingon Defense Force and other star navies, most notably the Lyran Starfleet.

The rank is equivalent to the Marines rank of colonel, wing commander in the Federation Starfighter Corps, the Cardassian Union title of gul, the Ferengi quasi-military title of daimon, and the Romulan and pre-Federation Vulcan rank of commander.

HoD was the Klingon term for the rank of captain. (The Dominion War Sourcebook: The Fires of Armageddon)

RIS Bouteina saw several HoDs: Golar was the captain of the IKV Naq'jej, while HoD Krug was the commanding officer of the IJN Eidolon.

In the 23rd century, the Gorn Space Command had two grades of captain: junior and senior captain. (TOS video game: Starfleet Command (game))

History

The term comes from the navies of Earth. The United States Navy abbreviation was CAPT.
