Fleet Admiral | (http://i175.photobucket.com/albums/w142/Dragonfire_Avitars/Archangel/Rank%20Pips%202387/r-a5.png) | Fleet Admiral is the highest rank in Starfleet. Fleet Admirals have many years of distinguished service and an impeccable record. There are only 6 Fleet Admirals: the Judge Advocate General, the Chief in Command, the Commander Starfleet, the Commandant of the Marine Corps, the Director of the Corps of Engineers and the Fleet Commander. |
Admiral | (https://i.imgur.com/c2OhaHD.pngg) | Admiral is the highest normal rank in Starfleet. Admirals have impeccable service records and decades of service. Flag Officers of Admiral rank are in command of all main divisions Starfleet with the exceptions listed above for Fleet Admirals. There are also 8 sector Admirals who are responsible for operations in their specific area, such as the Romulan Neutral Zone or Home Sector. |
Vice Admiral | (https://i.imgur.com/LCG2K6h.png) | Vice Admirals are Flag Officers who have a specific mandate, such as a subsection of a Division, or an area of space. Vice Admirals also command task forces. Most Armadas and Task Forces are assigned to Vice Admirals |
Rear Admiral | (https://i.imgur.com/ycaDI2p.png) | Rear Admirals are Flag Officers responsible for a limited and specific area for a limited time. Rear Admirals are usually promoted to Vice Admiral within two years. Rear Admirals may command major Starbases, Shipyards, Starfleet Bases on major worlds, or similar duties. |
Commodore | (https://i.imgur.com/E7XCZm8.png) | Commodore is the most junior flag officer rank of Starfleet, under the admiralty, but senior to a captain. Commodores command groups of ships, as opposed to captains commanding single ships or units. This could be thought of as a higher rank than captain, although it does not possess a permanent position in the rank hierarchy (a captain could also be directly promoted to the next highest rank, without spending time at a Commodore captain posting).
The rank of Commodore was used by Starfleet until at least the 2270's, when it was superseded. As of the rank revision of 2385, it has been reinstated. |

Captain | (https://i.imgur.com/ikFKB7e.png) | (https://i.imgur.com/FoJGR7l.png) | (https://i.imgur.com/jOpFc0p.png) | Captains are the most senior of line officers. Captains most often command Starships or Starbases of medium to large size. Captains may also command planetary outposts or serve as division heads for the Starfleet Bases on major worlds. |
Commander | (https://i.imgur.com/iutkR5u.png) | (https://i.imgur.com/wlaeBdg.png) | (https://i.imgur.com/oYlE61r.png) | Commanders are senior line officers. Commanders usually serve as the Executive Officer, Operations Officer, or Security Chief onboard a starship. Commanders may command small starships of under 100 crewmen, but this is rare. Commanders may also command small Starbases or minor outposts. Taking the Bridge Officer's Test is the only way for a science or medical officer to be promoted to Commander, pending completion of the other requirements |
Lieutenant Commander | (https://i.imgur.com/EhNHenN.png) | (https://i.imgur.com/sL0HsCK.png) | (https://i.imgur.com/TwpXp4B.png) | Lieutenant Commanders are senior line officers. Lieutenant Commanders usually serve as department heads aboard starship or on large Starbases. Lieutenant Commanders may be the executive officers on starships with a crew of less than 250, but usually Commanders fill that role. |
Lieutenant | (https://i.imgur.com/p7P4DFN.png) | (https://i.imgur.com/Auso973.png) | (https://i.imgur.com/WNivaVH.png) | Lieutenants are the most common Commissioned Officers. Lieutenants can perform almost any Officer duty on a starship, save for being the Commanding or Executive Officer. In some cases Lieutenants can even be department heads, especially on smaller starships. |
Lieutenant jg. | (https://i.imgur.com/JwNHZZu.png) | (https://i.imgur.com/gw0jQ7c.png) | (https://i.imgur.com/EpAtx7m.png) | Lieutenants Junior Grade are junior Commissioned Officers. Lieutenants Junior Grade may be the Medical Officer or Science Officer on a mid to large space station, or man a Bridge Station. Officers typically spend around 2 years as a Lieutenant Junior Grade. |
Ensign | (https://i.imgur.com/E4vSX6a.png) | (https://i.imgur.com/8gqD1P6.png) | (https://i.imgur.com/7stCyIT.png) | Ensigns are the most junior of Commissioned Officers. Ensigns often serve as Flight Controller aboard starships, or Operations Officer on small Starships. Ensigns can also serve in relief or assistant capacities to most other positions aboard ship. It is rare, but not unheard of, for a Cadet at Starfleet Academy to be granted a temporary Commission of Ensign. This is only done in cases of truly outstanding grades. Officers typically spend around 3 years as an Ensign. |
