Starfleet Commissioned Officers

  • Fleet Admiral is the highest attainable rank in Starfleet. Fleet Admirals, Admirals, Vice Admirals, and Rear Admirals are addressed as "Admiral", not Rear, Vice, etc.
  • Commodores are addressed as "Commodore".
  • Captains and full Commanders are addressed as "Captain" and "Commander", respectively.
  • A Lieutenant Commander is addressed as "Commander" as well.
  • At his pleasure, a Commander and above may address a Lieutenant Commander as "Mister", but he should know that he is giving offense to the officer by implying that he is a junior officer.
  • The Commanding Officer of a vessel is called "Captain" in direct address, regardless of grade. Some smaller ships have captains which are not Captains; however, while on their vessels they are addressed as "Captain".
  • Junior officers are addressed either by their ranks or as "Mister Smith". They should refer to each other in this manner.
  • At the pleasure of senior officers, female junior officers may be called "Ms. Smith".
  • Officers with the rank Lieutenant Junior Grade are addressed as "Lieutenant" when addressed by their rank.

Warrant Officers

  • Warrant Officers hold their position by "warrant", and are considered to outrank all Enlisted grades.
  • WOs are generally found heading sub-departments such as Transporter Mechanisms or Shuttle Maintenance.

Enlisted Crewmen

  • Enlisted crewmen are addressed solely by their rank or by the word "Crewman".
  • Enlisted Crewmen can be called by last names, without "Mister" attached.
  • All "Crewmen" are called such, regardless of their grades, and all Naval Enlisted Crewmen of grades Petty Officer Third Class to Petty Officer First Class are called "Petty Officer".
  • All enlisted personnel of grades Chief Petty Officer to Master Chief Petty Officer are addressed as "Chief".
