The Republic Swift Fleet served as a fleet for the Galactic Republic's Navy during the time of the Great Sith War. After the Krath and Mandalorian offensive, the fleet began a counter-attack that spanned the Slice, originating at Humbarine and culminating at Ko Vari. Most notably, it was a participant in the Battle of Onderon and brought about the devastated state of a large portion of the Krath fleet at Ko Vari.
