Starfleet uniform (2140s-early 2160s)

The uniforms worn by from the 2140s to the early 2160s became the template for certain future incarnations of Starfleet uniform. This uniform design was in use for around two decades with little variation. ()
Following the formation of the United Federation of Planets, a new was introduced. ()
The 22nd century uniforms continued to be used even into the late 24th century by Starbase 80 command staff. ()
==Standard duty uniform==
===Jumpsuit===
====2150s====
Adopted as early as 2143, Starfleet personnel in service aboard starships, outposts, and at Starfleet Command on Earth wore navy jumpsuits displaying their specific division of service. Shown in the form of colored piping at the shoulders, Starfleet divisions were displayed in the following code:
* – Command division
*Red – Operations division
*Aqua – Sciences division
*Red and white – Flag officers
The Starfleet uniform itself also bore several distinctive features not present in uniforms of the later centuries, most prominent being several zippers and pockets, and an assignment patch (based on the wearer's home assignment) worn on the left sleeve. The uniforms were made out of a flame retardant material. ()
Fitted close to the body, the uniform jumpsuit closed at the front in addition to zipping at the cuffs and pant legs. The uniform was also marked by several pockets, lining the legs, arms and chest, with the pocket on the right bicep typically used to hold the wearer's communicator. The rank insignia, presented as rectangular pips, was displayed on the right chest, set within the division color piping. ()
====2160s====
By the year 2161, several modifications were made to the Starfleet duty uniform. New additions to the uniform included epaulets on the shoulders as well as an additional mission patch displaying the Starfleet logo worn on the right sleeve, and a name tag worn inside the piping above the left breast. ()
In an alternate timeline where Captain Jonathan Archer was infected with interspatial parasites, Starfleet continued the use of their 2151 uniforms until 2165. They did not adopt the addition of personnel names and Starfleet membership patches onto the uniform by 2161, as they did in the regular timeline. ()
====2380s====
By 2382, the uniform was still in use aboard facilities such as Starbase 80, though its design had been modified. The mission patches and name tags were absent, and the division-colored piping on the shoulders had a metallic sheen, though it was still assigned the 2160s color schemes. Additionally, any visible rank insignia were gold and circular, rather than silver and rectangular, making them resemble the pips worn with the standard uniforms of the early 2380s. ()
===Shirt and pants===
The uniform jumpsuit was worn over a black, button-up mock turtleneck, blue pants with pockets, and heavy black, leather-like boots. ()
===Underwear===
For use beneath their uniforms, Starfleet personnel had at their disposal specific under garments for wear as early as 2151. This underwear was bright blue, trimmed in black. Both men and women wore boxer-brief-style shorts and tank tops. The female version of the tank top ended below the breast, leaving the midriff bare, while the male version went all the way to the waist. The underwear is reputed to be flame-retardant. ()
===Headgear===
Available for use with the excursion uniform and standard duty uniform was a black hat, embroidered with the specific registry number of the wearer's home assignment. Made of stretchable material, these hats were essentially one-size-fits-all "baseball caps." While these caps were generally worn during away missions, some officers wore theirs aboard ship. ()
==Flag officer uniform==
Similar to the duty uniform, a separate uniform was in service for Starfleet's higher-ranking flag officers, including commodores and admirals. Bearing the same style division piping, though restricted to red and white in color, the flag officer's uniform was a navy blue, two-piece style uniform, far more formal than the standard duty jumpsuit. It was worn over a white, button-up dress shirt and navy blue necktie. Displaying the wearer's rank insignia on both shoulders, the uniform also featured wide red and white piping on the cuffs. ()
==Dress uniform==
For diplomatic or other formal functions, a dress uniform was also available to Starfleet personnel as early as 2161. Also bearing the same style division color piping around the shoulders, the dress uniform was a brighter blue than the standard duty uniform and a more formal, two-piece jacket and trouser set. Similar to the flag officer's uniform, the dress uniform also had stripes around the cuffs indicating rank which was also displayed on both shoulders. Worn over a white tunic with a mandarin collar, the dress uniform was marked by two mission patches – one bearing the Starfleet logo on the right sleeve, and one bearing the individual assignment patch on the left. ()
==Excursion uniform==
For use in desert or other more inhospitable terrains, specialized uniforms were available to Starfleet personnel serving aboard starships. Consisting of a tan long-sleeve shirt, trimmed in black piping and zipping at the collar, the uniform was worn over khaki pants similar to the trousers of the standard duty uniform. Also worn with a black belt, the uniform displayed the ship's assignment patch on the left shoulder and the wearer's rank insignia on the right collar. Optional sunglasses were also available. ()
==Excursion jackets==
Excursion jackets were issued in a variety of colors and materials, maintaining the familiar division color stripes and uniform patches of the duty uniforms. Some, but not all, of the jackets featured rank insignia. ()
===Type A===
Available as early as 2151, a heavy, quilted uniform jacket, blue-gray in color was used in colder climates. Worn over the standard duty uniform, this heavy jacket featured a traditional collar, and zipped at the front, bearing several pockets. () This type of jacket was still in use as late as November 2154, worn by Starfleet officers stationed on Earth. ()
===Type B===
A second jacket option was also available aboard Starfleet vessels and shuttlepods in the 2150s. Gray in color, the jacket was essentially a thinner version of the previous design, retaining the same division color and pocket configuration, but abandoning the quilted look.
By the year 2161, the jacket was modified slightly. Coinciding with the alterations made to the standard duty uniform, the excursion jacket gained a second mission patch (on the right sleeve) and a nametag (worn on the left breast). ()
===Type C===
In use aboard starships such as the as early as 2154, a third jacket option was available for excursions into hot, dusty or desert terrain. Worn over the khaki excursion uniform, this long jacket was tan and featured black piping around the shoulders where the division color piping would be located on a standard duty uniform or excursion jacket. This jacket also had rank insignia on the collar. This jacket also had pockets, one on each side of the chest. Unlike the other two jacket designs, this version did not display a mission patch. ()
==Arctic gear==
Starfleet cold weather gear consisted of several layers of clothing. A gray shirt with a prominent white stripe running down the sleeves. Over this a set of dark-green and brown overalls was worn, along with a thick, hooded jacket, gloves, and boots in the same colors. This uniform was in use as early as 2152 and available to officers serving aboard starships and at Starfleet Command on Earth. An assignment patch could be affixed to the left shoulder of the jacket.

==Medical attire==
In medical situations requiring sterile conditions, Starfleet issued at least two sets of attire.
In 2151, a white shirt and pants set were used on Earth. This set had matching white boots and gloves. ()
In 2152, a silver, rubber-like set of scrubs were available aboard starships. These scrubs included similar silver gloves and white pants. ()
In 2382, Dr. Harrison Horseberry wore a lab coat over his standard jumpsuit in his role as Starbase 80's chief medical officer. ()

==Engineer's vest==
Engineers, at least during this uniform's later use on Starbase 80, also had the option of wearing a black vest with pockets with red lining to hold various engineering tools. This vest was worn over the standard duty uniform. ()
==Active wear==
For use in more casual circumstances or during physical exercise and training, active wear was available to Starfleet officers serving at Starfleet Command on Earth as early as 2143. Among the options was a light-gray long sleeve shirt with dark-gray trim at the sides and beneath the arms. The shirt was marked by a name tag adorning the right breast and a Starfleet mission patch worn on the left sleeve. This tunic was sometimes worn over standard duty uniform trousers. ()
==Provisional uniform==
Similar in design to the standard duty uniform, a gray jumpsuit was available to personnel serving aboard, or visiting, United Earth vessels in the 2150s. Featuring none of the familiar mission patches, rank insignia, or division color piping, this plain jumpsuit bore a high collar that zipped all the way at the front. It also featured several pockets on the chest, arms, and legs of the jumpsuit and was worn with the same black boots that were worn with the standard duty uniform. ()
==Adapted uniform==
After receiving a Starfleet commission in 2154, Vulcan Commander T'Pol wore a uniform design adapted from her civilian jumpsuits during her service aboard Enterprise. Retaining the same basic appearance, her jumpsuits gained division color piping at the shoulders, rank insignia on the right breast, and an Enterprise assignment patch worn on the left sleeve.
By 2161, T'Pol's uniform also gained a name tag and Starfleet patch worn on the right sleeve, per the alterations made to the standard duty uniform. ()

===Background information===
The Starfleet uniforms introduced in were designed by Robert Blackman, based upon William Ware Theiss' designs for Star Trek and . The uniforms also resembled those worn by Zefram Cochrane and the mission crew of the warp-ship Phoenix during their historic mission seen in . 
While Gene Roddenberry had dictated that zippers, buttons and other "modern" closures would be antiquated by the time of the 23rd and 24th centuries, Blackman utilized an abundance of zippers and buttons in his costume designs for Enterprise indicating its position in time before the original Star Trek. Each suit had 13 zippers. Because the zipper pulls were custom made, they didn't make it through the dry cleaning process very well. As a result, the color on the pulls had to be touched up after each cleaning.
The prototype suits were created with different features on each side of the suit so that producers could get an idea of all of the possible features the finished suit could have.
Several costumes and costume components were sold off on the It's A Wrap! sale and auction on eBay, including several pairs of boots, made by Alfani in Italy.

In an interview in Star Trek Monthly, Robert Blackman noted lieutenant junior grade and lieutenant commander were intentionally not to be included in the costume design. An article in on the 2151 uniforms and rank did not mention either rank.
In the mirror universe, the Terran Empire counterparts did use lieutenant commander, however, as well as fleet admiral and at least one grade of non-commissioned officer (where the prime universe used only crewmen to represent enlisted personnel.
===Apocrypha===
The Starfleet Operations Manual (p. 12) suggests this uniform was in use from "c. 2113–2161".
In the Rise of the Federation novel A Choice of Futures, these uniforms were phased out in favor of a new standardized uniform that used elements from all of the Federation's founding members.
