Sector Fleet

Sector Fleets were, in several governments, the offical terms given to describe the military forces in a sector (although other governments most likely used it in an informal setting).

The usage appears to have begun in the Old Republic during thr Clone Wars. The Fifth Fleet of the Open Circle Fleet was one such Sector Fleet.

During the time of the Galactic Empire, fleet admirals commanded Sector Fleets.

The term took on new meaning in the Imperial Remnant. There were eight Sector Fleets, one for each of the remaning Imperial sectors. They held around a dozen star destroyers each, and were under the direct command of the sector's moff. At the Supreme Commander's discretion, Sector Fleets could be assimilated into the Imperial Starfleet proper, as was done during the Yuuzhan Vong War.
