Real World Definition
In the United States Navy, the United States Coast Guard, the United States Public Health Service Commissioned Corps, and the National Oceanic and Atmospheric Administration Commissioned Corps, commander (CDR) is a senior officer rank, with the pay grade of O-5. Commander ranks above lieutenant commander and below captain. Commander is equivalent to the rank of lieutenant colonel in the other uniformed services.
A Commander in the U.S. Navy may command a frigate, destroyer, submarine, aviation squadron or small shore activity, or may serve on a staff (typically as executive officer). An officer in the rank of commander who commands a vessel may also be referred to as "Captain" as a courtesy title, or informally referred to as "skipper."
Historically, the rank of "Commander" was originally called "Master Commandant" in the U.S. Navy. This rank corresponded in function to "Master and Commander" in the Royal Navy. It was later changed in 1838 to its modern form.
In the U.S. Maritime Service, an auxiliary service, the grade of Commander is appointed by the President via the Secretary of Transportation, making it a federally recognized rank with corresponding paygrade of O-5.
Definition in the Star Trek Universe
Commander is a rank used by the service organizations of many civilizations.
As a traditional naval grade in Human usage, commander is the second most senior line officer rank, falling between a captain and a lieutenant. On Earth, the United States Navy used this rank as well as the Royal Navy. A rank of lieutenant commander also existed in these organizations, viewed as a lieutenant granted the authority of a commander. The United States Navy used the insignia of three solid sleeve stripes to denote the rank of commander and considered the rank the equivalent of a lieutenant colonel.
The ancient sea of rank commander was usually given to ship executive officers, department heads on larger naval vessels, or to the commanders of shore installations. The watch station of command duty officer was a position which could be held by a commander. (Star Trek IV: The Voyage Home)
In infantry forces, a commander was any CO.
In the galaxy, the modern rank of commander is typically held by the first officers of various cultures' starships and is also granted to the commanding officers of the smaller outposts, space stations and starbases.
In Starfleet, a prerequisite to becoming a commander is by taking the Bridge Officer's Test. As commanders prove their leadership ability over time, they are considered for the difficult and highly competitive promotion to captain. (TNG: "Thine Own Self")
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. (DS9: "Behind the Lines")
The rank of commander in the Romulan Star Empire is considered the equivalent of a Starfleet captain. (TNG: "Future Imperfect") Also, a subcommander grade exists in the Romulan military, with this rank also used in the 22nd century by the Vulcan High Command.
- According to The Making of Star Trek (page 256) the Romulan rank of commander is the rank of someone who commands a fleet of ships. This would imply it to be equal to the Federation Starfleet rank of commodore.
The 23rd century Imperial Klingon Fleet used the rank of commander to denote the commanders of smaller space vessels, such as a Bird-of-Prey. (Star Trek III: The Search for Spock) A Klingon rank of captain was used for larger vessels with this title carrying over to the 24th century Klingon Defense Force. (TOS: "The Trouble with Tribbles"; TNG: "Redemption")
Use of the rank in Star Trek: Second Fleet Online
