Ranks
| Flag Officers | ||
 |
Admiral is a military rank. As a traditional grade, admiral is the most senior flag officer rank of a naval organization, senior to a captain. Admirals command fleets of ships, as opposed to captains commanding single ships or units. | |
 |
Vice-admiral is a military rank. As a traditional grade, vice-admiral is a flag officer falling superior to a rear admiral and below a full admiral of a naval organization. This rank is used by the Federation Starfleet (as well as its predecessor the Earth Starfleet). Vice-admirals command entire fleets of vessels, divisions at Starfleet Headquarters, starbases and other senior positions in the fleet. | |
 |
Rear admiral is a flag officer rank used by naval organizations, traditionally between the grades of commodore and vice admiral. |
|
 |
Commodore is a naval rank. As a traditional grade, commodore is the most junior flag officer rank of a naval organization, under an admiral rank (usually under rear admiral) but senior to a captain. Commodores command groups of ships, as opposed to captains commanding single ships or units. |
| Line Officers | ||
 |
The rank of Captain is the highest rank one in Starfleet can achieve and still be a line officer. Captain's usally are CO's of starships, but there are exceptions. | |
 |
Commander is a military rank. As a traditional naval grade, commander is the second most senior line officer rank, falling between Captain and Lieutenant in hierarchy, usually given to first officers and department heads, or the skippers of smaller vessels or leaders of other contingents of officers, such as on a Starbase. Proper naval parlance says that, even if a naval vessel is commanded by an officer whose rank is commander, that officer is still able to be referred to as a captain while on the deck of their own vessel. |

 |
Lieutenant Commander is a military rank. A traditional naval rank, lieutenant commander is the grade between lieutenant and commander grades. | |
 |
Lieutenant is a rank used by Starfleet. It is between a Lieutenant (Junior Grade) and a Lt. Commander. A rank of Lieutenant is a common rank in Starfleet. | |
 |
Lieutenant (Junior Grade) (often abbreviated to lieutenant J.G.) is a military rank. A naval rank in a small number of Earth's ancient navies (such as the United States Navy), it is placed between ensign and full lieutenant. The rank is used primarily by the Federation Starfleet, although its Earth predecessor (from which it primarily takes its rank structure) may also have had this grade. It is unclear if the grade exists in other cultures' rank arrangements, although it may correspond to the Romulan rank of sublieutenant. |

Ensign is a military rank. As a traditional naval grade, ensign is the most junior line officer rank below the lieutenant grades, usually immediately under lieutenant or lieutenant (Junior Grade). This naval rank is equivalent to the infantry rank of first lieutenant. An ensign's primary duty is professional growth, both as a leader and as a occupational specialist. Ensigns are mentored by more senior officers as well as their (nominally) subordinate chief petty officers as part of their development as Starfleet leaders. As ensigns prove themselves more capable, they are considered for promotion into the lieutenant tier. In the 24th century uniform scheme of Starfleet, ensigns were once again indicated by one single rank pin. |

Master chief petty officer (MCPO) was an enlisted naval rate, a type of military rank used by the service organizations of different cultures. As a traditional naval grade, MCPO was the most senior grade of chief petty officer, and was almost the highest noncommissioned officer grade in organizations like Starfleet and the US Navy. In comparison to infantry ranking systems, this rate was approximately equivalent to the most senior sergeant grade, such as Sergeant-Major. Personnel of this grade could be addressed simply as chief (or more properly, "master chief"), and sometimes by their job title, such as "master chief specialist." | |
 |
Senior chief petty officer (SCPO) was an enlisted naval rate, a type of military rank used by the service organizations of different cultures. As a traditional naval grade, SCPO was senior to a chief petty officer, and was almost the highest enlisted grade in organizations like Starfleet and the US Navy, falling subordinate to any commissioned officer. In comparison to infantry ranking systems, this rank was approximately equivalent to the first sergeant grade. When there are individual grades of chief petty officers, SCPO was subordinate to master chief petty officer (MCPO). This rank was considered to have the responsibility of a "noncommissioned officer." Personnel of this grade could be addressed simply as chief (or more properly, "senior chief"), and sometimes by their job title, such as "senior chief specialist." (DS9: "Shadowplay") | |

Chief petty officer (CPO) is an enlisted naval rate, a type of military rank used by the service organizations of different cultures. As a traditional naval grade, CPO is senior to a petty officer, and is the highest enlisted grade in organizations like Starfleet and the US Navy. In comparison to infantry ranking systems, this rank is approximately equivalent to the more senior sergeant grades. Personnel of this grade can be addressed simply as chief, and sometimes by their job title, such as "chief specialist." | |

Petty officer First Class was an enlisted naval rank, a type of military rank used by the service organizations of different cultures. This title was senior to a crewman, and subordinate to a chief petty officer. In comparison to infantry ranking systems, this rank was approximately equivalent to the grade of Corporal. However, the Petty Officer 2nd Class rank was equivalent to that of Sergeant and the 1st Class rank was equivalent to that of Staff Sergeant. This was the lowest rank considered to have the responsibility of a "noncommissioned officer." Personnel of this grade were usually referred to by their job title. In Starfleet, a petty officer could be referred to as yeoman, or as specialist. There were usually individual grades of petty officers, differentiated as first, second and third class. This appellation could be added to either their rank or title (i.e. "petty officer first class," "specialist second class," or "yeoman third class"). | |

The grade of crewman may further be divided into several "classes", such as "crewman first class", "crewman second class", etc. | |
