"A SUBRON usually consists of three or more submarines. It is the submarine force equivalent to a Destroyer Squadron in the surface Navy. The officer in charge of SUBRON ONE is designated Commander Submarine Squadron One or COMSUBRON ONE. However, unlike a destroyer squadron—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."

Squadron Commanders

"Clay Blair provides a list of assigned Squadron Commanders as an appendix in Silent Victory"

"Please note that during the war Squadrons were purely administrative in nature, and squadron commanders did not control the operations of the boats assigned to them."

Squadrons - SUBRON's:
SUBRON 1, SUBRON 2, SUBRON 3, SUBRON 4, SUBRON 5, SUBRON 6, SUBRON 7, SUBRON 8, SUBRON 10, SUBRON 12, SUBRON 13, SUBRON 14, SUBRON 16, SUBRON 17, SUBRON 20, SUBRON 22, SUBRON 24, SUBRON 26, SUBRON 28, SUBRON 30, SUBRON 32, SUBRON 34, SUBRON 36, SUBRON 45, SUBRON 50

The table listing the Subrons lists commanders, and a little more digging will tell you 'which were where'.

Happy Hunting!
