Lieutenant

This article describes the Starfleet rank. For the infantry ranks see first lieutenant and second lieutenant.

Lieutenant is a military rank used in Earth Starfleet and Federation Starfleet, superior to ensign and lieutenant junior grade and subordinate to lieutenant commander and commander. Lieutenants are often technical specialists (navigator, communications officer), heads of small sections, or second-in-command of larger sections (under a lieutenant commander).

The corresponding infantry and Starfighter rank is captain. The rank is also used by the Kellarian System Defense Forces (Star Trek: Remington).

Sogh was the Klingon term for a lieutenant. A platoon of 25 warriors was commanded by a Sogh. (The Dominion War Sourcebook: The Fires of Armageddon)

History

The term comes from the navies of the 20th century. The USN abbreviation was LT.

In the 20th century the word was pronounced 'lef-tenant' by English speakers, except in the USA, where the more regular pronunciation 'loo-tenant' took hold with the help of spelling reformers of the 19th century. Non-Earthians use the American pronunciation. Some Earth people use the traditional pronunciation. (TOSS #11 "Ensign Null")

The Romulan Star Navy and Romulan Ground Forces have ranks that in English are called lieutenant. In the Star Navy it is the rank above sublieutenant and below centurion, while in the RGF it is above sublieutenant and below captain.

Andorian Imperial Guard have ranks that in English are called lieutenant.
