Lieutenant is a commissioned officer rank in many service organizations, including police, military, naval services and space forces, most notably the Federation Starfleet.
Standing[]
A lieutenant is a low-level line officer rank, in naval organizations a grade higher than a lieutenant junior grade and a grade below lieutenant commander in most rank structures, although some organizations may differ or omit certain ranks. The lieutenant rank is roughly equivalent with the authority of a infanty captain of military forces. The lieutenant grades of such military units are generally divided up as second lieutenant and first lieutenant
In the Romulan Star Navy, the rank of lieutenant is normally used but an additional equivalent, trinam, also exists on some branches. (FASA RPG module: The Romulan Way)
In the Cardassian language, glinn is a Cardassian officer rank title which, in translation to Federation Standard, is approximately equivalent to a lieutenant . (TLE - Terok Nor novel: Day of the Vipers)
A lieutenant in Starfleet may be assigned as a department head or senior staff member of a mid-to-large size command such as a capital ship or space station. Some examples include Communications Officer Nyota Uhura of the USS Enterprise, Security Chief Worf of the USS Enterprise-D, Tactical Officer Tuvok of the USS Voyager or Chief Science Officer Jadzia Dax of Starbase Deep Space 9. (TOS; TNG; VOY; DS9)
A lieutenant could also serve as the first officer of a smaller starship or the second officer or third officer of a mid-size vessel. First Officer Ezri Dax of the USS Defiant and Second Officer Tuvok of Voyager filled these roles, respectively. (DS9, VOY)
In the Klingon Defense Force, the rank of lieutenant is represented by a rank insignia of a stylized, bi-segmented shape, within a circle. (FASA RPG module: The Klingons: Star Fleet Intelligence Manual)
