Tector-class

The Tector-class was a class of Star Destroyer in the service of the Imperial Navy during the Galactic Civil War. It notably differed from other Star Destroyer classes, as it lacked a ventral hangar bay. In 4 ABY, one Tector-class vessel, Harbinger, was part of the Galactic Empire's fleet defending the second Death Star over the Forest Moon of Endor.

After Rebel Alliance forces launched an assault on the seemingly incomplete battle station, the Imperial fleet trapped them, as planned by Emperor Palpatine. Just as the Alliance began attacking the Imperial ships, the rebel freighter Millennium Falcon crossed the hull of the Harbinger. The Star Destroyer was later destroyed by advancing rebel vessels, and shortly after, the Death Star itself was destroyed, along with a large portion of the gathered Imperial forces.
