High Quality Content by WIKIPEDIA articles! SUBRON is the United States Navy (USN) abbreviation for Submarine Squadron. A SUBRON usually consists of three or more submarines. It is the submarine force equivalent to a Destroyer Squadron or DESRON in the surface Navy. However, unlike a DESRON -- which actually moves its staff aboard its ships and deploys with them as an operational Task Element commander -- a SUBRON commander and his staff always remain in homeport, and are responsible only for the training, equipping and administering of the ships under its umbrella. A submarine squadron is usually commanded by a Captain (O-6) who has already had at least one tour as commander of a submarine. Up until World War II and possibly afterwards, submarine squadrons could have several Submarine Divisions (SubDivs), often pairs of submarines.
