Branch Admiral
From WNOHGB Wiki
A branch admiral is a flag rank unique to Starfleet.
Historical Context
Prior to Stardate 66065.57, Starfleet titled the "one-star" rank as a Junior Admiral (JADM). When Vice Admiral Jacob Hathaway was appointed Chief of Starfleet Operations, Directive #1 from his new office was to have that rank renamed to its current title of Branch Admiral (BADM).
Before the advent of the title Junior Admiral in 2365, this rank was known as a Rear Admiral (lower half) (abbreviated as RDML) in Starfleet.
Starfleet Usage
In Starfleet, Branch Admirals must have a minimum of twenty years service as a commissioned officer before being considered for promotion to flag rank. It is preceded by at least six months' service as a Commodore. Branch Admirals are often placed as Fleet and Task Force Commanding Officers, or as Starbase COs. They may also be appointed as deputy chiefs at the division level (ie: Deputy Chief of Starfleet Science), in rare cases as a Chief of a Division (most likely in an acting capacity).
Starfleet used the following rank insignia to denote this rank of officer:
| Period | 2410-Present | 2373-2410 (as JADM until 2388) | 2368-2373 (as JADM) | 2365-2373 (as JADM) | 2352-2365 (as RDML) | 2280-2352 (as RDML) | 2270-2280 (as RDML) | 2255-2270 (as RDML) |
