Ensign is a rank used in Earth Starfleet and Federation Starfleet. Ensign is the most junior officer grade subordinate to lieutenant and lieutenant junior grade. Most graduates of Starfleet Academy, both Federation and Lyran, are assigned this rank and spend their first year or two earning their promotion to the lieutenant grade.

The corresponding rank in the Romulan Star Navy is sublieutenant, in the Marines is second lieutenant, and in Federation Starfighter Corps is lieutenant.

The rank was also used by the Kellarian System Defense Forces (Star Trek: Remington).

Also, the Hydran Royal Navy used the rank of ensign in both its ground forces and space forces. In both cases, the rank of ensign was the lowest rank of commissioned officers. The rank of Cornet was equivalent and used interchangeably among Hydrans. (RIS Bouteina: "Forlorn Hope")

History[]

The term comes from the armies of France's Ancien Régime, where the ensign was the flag bearer of a battalion or a regiment. However, it was used in the wet navies of that era as well. The United States Navy abbreviation was ENS.
