This system would be in use concurrently with other rank insignia systems for at least fifteen years, with only a slight modification in the early 2260s, when those holding the rank of captain were authorized to wear two gold stripes whereas other officers wore one. Commissioned officers wore a solid gold stripe.

( ST: ' The Trouble with Edward')ДЄnother uniform used around this time had a much simpler rank and insignia system, in which enlisted personnel wore no rank insignia while the rank of chief petty officer was denoted by a special sleeve stripe. Some USS Cabot crewmembers wore uniforms without rank insignia, though it wasn't established what this represented. ( DIS: ' The Vulcan Hello', ' The Butcher's Knife Cares Not for the Lamb's Cry')ДЄnother variation of this uniform introduced alongside this uniform in the 2250s changed the rank system back to a sleeve stripe system. The Admiralty wore a Starfleet insignia surrounded by a wreath made up of smaller golden Starfleet insignias on a dark disc, with more insignia indicating a higher rank. A captain's uniform also featured additional golden trim between the shoulders and the collar. ( ST: ' The Brightest Star') Command wore a golden shield with a five-point star, operations wore a bronze shield with an angular swirl, sciences wore a silver shield with a circular insignia, and medical wore a silver shield with a cross insignia. Gold shoulder trim of a flag officer, captain, and officer (left to right)Д«y 2239, Starfleet had adopted a uniform where officer rank was denoted by the number of raised or indented pips on a delta shield badge of the Starfleet insignia, featuring an icon representing their division. The rank of lieutenant commander was not seen on Star Trek: Enterprise or depicted prior to 2233. ( ENT: ' These Are the Voyages.')Д«y the 2230s, the Starfleet uniform used a sleeve stripe system instead of pips to denote rank. Rank was displayed on the right breast of the Starfleet uniforms, above a colored shoulder trim denoting what department the crew member was assigned to ( command gold, operations red, or sciences blue.) ( ENT: ' First Flight', et al.) This insignia and system was still in place in 2161. By the development of the NX-Alpha in 2143, Starfleet rank structure had at least three enlisted positions, four officer ranks, and three ranks for use by flag officers.
