This uniform, consisting of a one-piece flight suit over black undergarments, was in use during the first flight of the original starship Enterprise under Captain Jonathan Archer. Rank was on the right shoulderpiece, with department color edging on both shoulders. Established blue as the color for science and medical fields.
Uniforms during this era consisted of a department color shirt with ship/station insignia on left breast and rank insignia in gold piping on the egde of both sleeves, black pants and boots.
This era's uniforms were similar to the previous ones with the addition of black collar trim. Male uniforms included black pants and boots, while female uniforms had the shirt extended into a short skirt of department color and black boots.
Harkening back to the one-piece flight suits of earlier eras but with more organic colors, these uniforms consisted of a one-piece beige uniform with attached boots. Department is signified by the background color of the ship/station insignia, with orange indicating sciences. Rank piping remained as previous eras on the sleeves but also included shoulder pips.
Uniforms from this era have a more military design, with a standard jacket with belt, pants, boots, and a realigned department color turtleneck. Sciences, communications and navigation were all indicated with a gray turtleneck. The Enterprise insignia was adopted as the standard Starfleet insignia and used on the belt and breastpin. Rank was indicated with a right shoulder insignia, and pips showing years of service were used on the left sleeve. During the later part of this era the turtleneck was abandoned for a standard neckline shirt, the belt was eventually dropped, and the Starfleet breastpin was replaced by the new Starfleet-insignia communicator.
Eventually the military style of the earlier era was replaced by a one-piece uniform, with black legs and boots and a stylized top of the traditional blue department color. Rank was indicated by gold and black pips on the right collar, and the Starfllet-insignia communicator is worn on the left breast. Male and female variants included a short 'skant' or skirt.
Standard uniforms during this era were a minor two-piece modification from the previous one-piece jumpsuit, primarily for comfort reasons. Rank pips were used on the newly-added collar with department-color trim. Also in use during the later part of this era was a one-piece jumpsuit, primarily black with department color shoulders and a gray turtleneck underneath. Cadet uniforms were similar to the jumpsuit, with gray replacing the black and full collar instead of a turtleneck.
Similar to the previous jumpsuits, the standard uniform from the current era have gray shoulders with a department-color turtleneck. Special-environment uniforms are also used, and include department color in some way.
Several temporal-based activities have revealed a possible design for the future of Starfleet. The form-fitting uniform uses a department color top and black pants with boots.
