The Renown was a Venator class Star Destroyer in the service of the Republic Navy's Open Circle Fleet during the Clone Wars. In 20 BBY, it was stationed with two other Venator class star destroyers under the command of High Jedi General Obi-Wan Kenobi in the Tervissis system, when they were attacked by a Separatist fleet commanded by General Greivous. Droid boarding parties arrived on both the Renown, and the flagship, Negotiator. Although the Negotiator was destroyed when Kenobi set it to self-destruct, the Renown was overcome and it's crew was captured.
The Renown was later used by the Confederacy in Operation: Trepidal, in which it was loaded with Rhydonium fuelcanisters above the mining planet of Abafar, and was intended to be rammed into the Republic space station Valor, site of the Republic strategy conference. However, D-Squad, with the aid of clone commando Gregor, managed to get on the ship, and being warned of the threat, managed to overpower the B1 battle droids and the Pistoeka sabotage droids (where M5-BZ sacrificed himself to save the others), and with the help of the heroic deed of R2-D2, barely managed to destroy the ship before it reached the starbase.
