Relentless, a Republic Navy vessel of the cruiser class, saw action in the Clone Wars.
Under the command of Captain Meeba, the Relentless served as the flagship for Strike Force Cularin throughout the Clone Wars. Along with the rest of the strike force, the ship journeyed to the Ando system and took part in a mission aimed at eliminating a Confederate installation established there.
Subsequently, the warship proceeded to Coruscant to collect Osten Dal'Nay, Lanius Qel-Bertuk, and Lavina Wren, with the intention of transporting them to the Cularin system. Leading a formation of twelve vessels, the Relentless arrived at its destination and engaged in the Battle of Cularin.
