Redoubtable began its service as one of the initial Imperial I-class Star Destroyers. It subsequently underwent a name change, becoming known as the Destiny of Yevetha.
Following extensive damage sustained during the withdrawal from the Battle of Endor, the vessel was dispatched to the Black-15 shipyard located at N'zoth. During the Yevethan rebellion, Nil Spaar of the Yevetha captured the ship and renamed it to the Destiny of Yevetha. Once the Yevetha had completed the necessary repairs, the ship was put into service in the Yevethan fleet throughout the duration of the Black Fleet Crisis.
Redoubtable made a hyperspace jump to Byss situated in the Deep Core, accompanied by other starships of Imperial design that departed from the Yevethan fleet under the leadership of Sil Sorannan.
