By the time of 18 ABY, only three had been known to be built: Watchkeeper, Defender, and Sentinel. But there could have been more in the defense fleet, as it was later stated by Admiral Hortel Ossilege said that he could not leave the Bakuran System without defense during the Corellian Crisis, hinting there could have been a larger force of these destroyers. These three destroyers were the only known destroyers equipped with experimental Hyperwave inertial momentum sustainers or HIMS.
The New Republic convinced the Bakuran Senate to deploy the three destroyers on the Republic's behalf during the Corellian Crisis, due to the fact that their interdiction fields would prove necessary against the likewise-equipped Sacorrian fleet, and the fact that the New Republic Defense Fleet was largely incapacitated due to the events of the previous year. Only Defender and Sentinel would return to Bakura following the subsequent Battle of Centerpoint Station.
Behind the scenesEdit
Although this class of starship is not called "Star Destroyer" by name, it is designated as such in Cracken's Threat Dossier.
