A lieutenant commander is a senior department officer or the executive officer (second-in-command) on many warships and smaller shore installation, or the commanding officer of a smaller ship/installation. They are also senior department officers in naval aviation squadrons.
Etymology
Most Commonwealth and other navies address lieutenant commanders by their full rank or the positions they occupy ("Captain" if in command of a vessel). The United States Navy, however, addresses officers by their full rank or the higher grade of the rank. For example, in day-to-day speech, a Lieutenant (junior grade) is abbreviated as "Lieutenant," and a Lieutenant Commander is abbreviated as "Commander."
The rank insignia for a lieutenant commander is two ½-inch (13 mm) stripes with a ¼-inch (6.4 mm) stripe between, worn on the cuffs of the service dress jacket, and on slip-ons on other uniforms. As senior officers, they wear one row of gold oak leaves along the edge of the visor of their service caps. Lieutenant commanders of the Naval Operations Branch wear the officer's pattern of the branch cap badge: an anchor on a black oval, surrounded by a wreath of maple leaves at the sides and base of the oval, the whole surmounted by the St Edward's Crown. Specialist officers in such branches as logistics, intelligence, medical, etc., wear their branch cap badges.
While there are many costumes from the Star Trek television series and motion pictures, the ones worn by actors portraying enlisted personnel and officers from the fictitious organization Starfleet are the ones most closely associated with Star Trek costuming. Design varied among the successive costume designers, although generally costumes and insignia were consistent within any one series or film. Costumes were re-designed to improve appearance when filmed and to improve the comfort for actors. Deliberately mixing styles of uniforms from the various series was occasionally used to enhance the sense of time travel or alternative universes.
Original Series
The original uniform designs were the product of designer William Ware Theiss. The original series uniforms consisted of a colored top and dark pants, with significant variations between the designs used in the pilot episodes and the rest of the series.
Pilots
The first uniforms, as seen in the unaired pilot "The Cage" (footage was re-used in a later episode, "The Menagerie") and again in the second pilot "Where No Man Has Gone Before", are somewhat different from the Starfleet uniform seen in the rest of the original series. The original concept used a heavy, ribbed turtle neck collar of the same color as the tunic for the men, with a cowl neck variation for the women, each in three colors: gold, beige, and light blue.
