Tector-class Star Destroyer

The Tector-class Star Destroyer was a Star Destroyer class in service with the starfleet of the Galactic Empire. Although it greatly resembled the contemporary Imperial-class, it had neither ventral hangar bays or ventral bulb. Instead, the design had thick armor panels running along the keel line, covering the areas normally used as hangar openings, as well as the power generator's bulb. At least one Tector-class ship, the Harbinger, took part in the Battle of Endor, in the twenty-fourth year of the Empire.

Behind the scenes
A hangarless Star Destroyer was briefly spotted in Star Wars: Episode VI Return of the Jedi. In April 2005, the name Tector was first used in the Legends reference book Star Wars: Revenge of the Sith Incredible Cross-Sections, although not explicitely in relation to the ship seen in Return of the Jedi. One year later, on May 5th, 2006, Leland Chee confirmed on the Official Message Board of StarWars.com that the hangarless ship from the movie was indeed a Tector-class Star Destroyer.

The first canonical source to use the name Tector-class was "The Levers of Power," a 2015 short story written by Jason Fry. On Twitter, Fry confirmed his authorial intent that the nomenclature still described the hangarless Destroyer from Return of the Jedi, and that the particular Tector seen in the movie was the Harbinger.
