The Tremendous was an Inexpugnable-class tactical command ship that served the Republic Navy during the Mandalorian Wars between the Galactic Republic and the Mandalorian warrior clans. The flagship of a battle group by the year 3963 BBY, the Tremendous at one point patrolled the area of the planet Myrkr and the Ryyk Nebula. After the Mandalorian devastation of the planet Serroco, Republic Admiral Saul Karath retreated and attempted to link up with the Tremendous and its battle group, but his flagship was destroyed before he got the chance.
