Lieutenant junior grade (often abbreviated to lieutenant jg), or junior lieutenant is a military rank, the equivalent of which is used by the service organizations of many civilizations. A naval rank in a small number of Earth's ancient navies (such as the US Navy), it is placed between ensign and full lieutenant. The rank is used primarily by the Federation Starfleet, although its Earth predecessor (from which it primarily takes its rank structure) may also have had this grade.

During certain points in its history, Starfleet discontinued the rank of lieutenant junior grade, promoting ensigns directly to the full grade of lieutenant. This was the case in the early 2270s, when ensigns adopted the sleeve insignia of the former lieutenant jg rank, the jg rank being done away with. Historical records also indicate that the Earth Starfleet did not use the rank during the 2150s.

An issue of Star Trek: The Magazine established that the costuming department on Star Trek: Enterprise had no insignia for lieutenant junior grade, although this does not necessarily mean the rank did not exist. Several pre-production publications regarding Star Trek: The Motion Picture established that the lieutenant jg rank also did not exist during the time frame of the film.

It is unclear if the grade exists in other cultures' rank arrangements, although it may correspond to the Romulan rank of sublieutenant.

Background information Edit

Only one officer in TOS wore a lieutenant jg insignia, Tormolen in "The Naked Time", even though some officers (for example, Charlene Masters and Marla McGivers) were referred to as "lieutenant" but wore no insignia at all, like ensigns. This particular rank is portrayed in every Starfleet rank scheme, but rarely mentioned in dialog.
