Starfleet Ninth Fleet

The Ninth Fleet was a Federation fleet that was operational during the 24th century.

Early in the Dominion War the Ninth was reassigned to assist the Third Fleet in the defence of the Sol system. (: "The Big E")

Captain Benjamin Sisko's plan to retake Deep Space 9 involved elements of the Ninth Fleet joining with elements of the Second and Fifth fleets along with a contingent from the Klingon Defence Forces. When the fleet was forced to launch prematurely due to the imminent collapse of the minefield the Ninth Fleet was still a day away from the staging ground at Starbase 375. 

The Ninth was diverted towards Deep Space 9 after the Federation task force left Starbase 375. It did not manage to catch up with the force until after the station had been secured. Once it was at Deep Space 9 Starfleet Command pulled back most of the Second and Fifth fleets for repairs and resupply. (: "Rode the 600", "Unfinished Business")

General Martok was made Supreme Commander of the Ninth Fleet following Operation Return.
