During the Clone Wars, a fleet served as part of the Galactic Republic's naval forces. This fleet was under the command of Jedi General Eeth Koth, who oversaw the fleet from the bridge of his flagship, a Venator-class Star Destroyer known as the Steadfast. In the year 21 BBY, subsequent to a battle that took place on the planet Geonosis, Koth and the ships under his command received orders to track down those responsible for the attacks occurring near Outer Rim Territories hyperspace routes. However, while the Steadfast was traveling through the Saleucami system, it came under attack from a Recusant-class light destroyer belonging to the Separatist Alliance's General Grievous. As a result, Grievous boarded the Star Destroyer, which culminated in Koth's capture following a short duel that occurred on the Steadfast.
The fleet commanded by Eeth Koth first appeared in "Grievous Intrigue," the ninth installment of the second season of the animated television show Star Wars: The Clone Wars, which was broadcast on January 1, 2010. It was later referenced as a fleet in "The Clone Wars Begin," a part of De Agostini's Star Wars Encyclopedia collection that was released on May 18, 2021.
