Starship and Space Station Positions
Starships and starbases have multiple positions for officers and crew. This article gives several of the most common positions, listed by department. The word 'unit' is used as short-hand to refer to either a starship or space station. While there are similarities across all units, individual commanding officers have wide latitude in developing a command structure that best suits their particular unit, so individual differences are common.
Command Division
The Command Division is denoted by the color red, and includes the unit-level departments of Command, Flight Control, and Strategic Operations.
Command Department
The Command Department includes both the senior-most officers of the unit, as well as administrative support personnel. On the largest units (such as starbases) there can be dozens of people in the command department, while on smaller units it may just be the senior officers and a yeoman or two. Smaller units also often combine command-related departments such as Intelligence or Diplomacy, if officers in those specialties are present.
Standard Command Positions
Commanding Officer
The Commanding Officer is the senior-most officer in charge of a unit. They have ultimate responsibility for the safety of their crew and for carrying out Starfleet's instructions. Aboard a starship, the commanding officer is always addressed as 'captain' even if they have a lower rank, but this custom does not apply to space stations. Starship commanding officers range in rank from lieutenant commander (for the smallest frigates and escorts) to fleet captain (for very senior captains aboard the largest ships), while for stations some of the smallest outposts (such as subspace relay stations) might be commanded by a lieutenant junior grade ranging to a full admiral commanding Starfleet's most important fleet yards.
Starships are rarely commanded directly by flag officers more senior than commodores. For the flagships of more senior officers, it is very common for the ship to have its own captain, who handles the day-to-day running of the ship. Historically, this officer would be called a flag captain, but the use of this term varies based on officers' preferences. Typically, a flag captain is relatively junior in seniority, given that they are closely supervised by their flag officer.
The captain of a starship has significant powers deriving from the difficulty of real-time contact with Starfleet, including the power to negotiate treaties and trade agreements when out of touch with Command. They also have authority over lesser vessels (such as tankers, freighters, passenger ships, etc.) during emergency situations. Similarly, commanding officers of starbases are often the senior-most officer in their sector with corresponding authority over starships in that sector.
Executive Officer / First Officer
The Executive Officer of a unit is second-in-command, responsible for assisting the commanding officer in carrying out their duties and taking command in their absence. Some of the XO's primary responsibilities are determining the duty schedule, performing crew evaluations, and ensuring that proper training has occurred for everyone aboard the ship. They are the interface between the CO and the crew, often serving as disciplinarian, career counselor, and supervisor to everyone on the ship or station. On a starship, the XO typically leads all away missions. XO's can range in rank from lieutenant to captain depending on the size of the unit. Whether they are called the Executive Officer or First Officer comes down to the CO's preference.
On larger commands, this role is most often separate, but on smaller vessels (and historically in Starfleet) it is often a dual-role for one of the department heads. In this case, they wear the color of the department that they also head.
Second Officer
The Second Officer of a unit is third-in-command after the Executive Officer. This role is almost always a secondary duty for a department head, and generally does not carry any administrative burden on its own, but rather is a title for the officer designated to take over, should the CO and XO both be absent. Traditionally, the second officer also accompanies away teams. Second officers wear the color of the department they head.
Yeoman
A yeoman is an administrative aid to a senior officer, or more generally a gopher and support staff member who helps with minor tasks (such as retrieving objects, sending messages, updating records, etc.). This position can be held by an enlisted member of Starfleet (i.e. a proper yeoman) or by a junior officer, such as an ensign or junior lieutenant wanting to learn more about command. Their usage is up to the officer they serve under, and ranges from all the way from handling clerical tasks to being a confidante and sounding board. The smallest units might not have any yeomen at all, but the largest might have dozens. Yeomen can also be found in other departments, handling similar tasks. Yeomen wear operations gold, rather than command red, to signify their support role.
Additional Command Positions
Records Officer
A unit's records officer is responsible for the accuracy of all logs, reports, and mission materials, and as such generally must have clearance nearly as high as the commanding officer's. They must ensure that everything that goes into the ship's log matches with other logs, and that the proper personnel and offices receive any reports filed. This was once a position found on all starships, but thanks to advancement in automation it is now often omitted. Due to the sensitivity of the information they deal with, this role is sometimes combined with that of the intelligence officer, should one be present.
Officer of the Watch
It is standard practice to have bridge-qualified department heads take the conn (i.e. command the bridge or operations center) when the captain, first officer, or second officer are otherwise occupied. Some starships have additional command department personnel who routinely stand watch on the bridge; most often this is a dedicated night-shift officer of the watch, but the largest ships might have up to six or seven officers between the rank of lieutenant junior grade and commander who are assigned to specific watches. This is more common aboard stations.
Command Master Chief
The Command Master Chief is the senior-most enlisted member of a unit, and might have additional responsibilities related to meeting the needs of the unit's enlisted population. This responsibility overlaps with the executive officer's responsibility for crew readiness and the counselor's responsibility to help address crew needs, and so it is rarely used in Starfleet, but some commanding officers employ it. As suggested by the name, this is generally a master chief petty officer, but lower enlisted grades could hold a modified title (Command Senior Chief, Command Chief, etc.) if necessary.
Flight Control
The Flight Control department combines the duties of piloting a starship, navigation, and/or handling docking procedures, as is appropriate to a particular unit. Large starships with shuttle bays will have all three of these duties represented, while space stations will only have to deal with docking procedures. This department is considered adjacent to command, and many officers move from this department into command just by virtue of their inherently greater experience with bridge operations than those in other departments. The vast majorities of roles in this department are positions that can only be filled by officers.
Standard Flight Control Positions
Chief Flight Control Officer
The Chief Flight Control Officer is responsible for the safe navigation and piloting of a starship, and/or coordinating the flight paths and docking needs of other vessels in the vicinity of a station or starship. The CFCO is a department head and generally has the helm personally for at least one shift per day, being the senior-most pilot aboard. The CFCO is also responsible for working with the ship's computer, stellar cartography section, and/or navigation section to ensure that courses are plotted efficiently and safely.
Assistant Chief Flight Control Officer
The Assistant Chief Flight Control Officer is the second-most-senior pilot or flight controller in a particular unit. As assistant department head, they help their department head determine a duty roster in coordination with the unit's executive officer. Otherwise, they have the same responsibilities of other flight control officers to take the helm for a shift on the bridge each day.
Flight Control Officer
Flight Control Officers are those officers who have a regular shift on the bridge or in station operations handling flight control duties. They can also be assigned to pilot small craft as necessary.
Relief Flight Control Officer
Relief Flight Control Officers are the most junior members of the flight control department qualified to pilot the ship or handle docking duties on a station. They are on-call for a particular shift, usually waiting in a room adjacent to the bridge or station operations, where they can quickly take over for a more senior officer at their station, should that officer be called away for some reason. They may occasionally also be given the helm for an entire shift, such as the night shift, and this is considered a training role, where they can accumulate enough hours of flight time to be considered fully-qualified.
