Tector-class Star Destroyer

The Tector-class Star Destroyer was a Star Destroyer class in service with the Galactic Republic and the Galactic Empire.

Characteristics
It was a 1.6-kilometer-long dagger-shaped vessel, essentially a version of the contemporary Imperial-class[2], with ventral hangars absent. Instead of ventral hangar bays, the design opted for an increase in armor that covered the areas normally used as main hangar openings,[1] as well as the reactor core.[3]

This made the design more efficient in ship-to-ship combat, as it had less access to internal weak-spots. However, it limited its usefulness in other roles. Being without hangars, it required dedicated carriers to provide any starfighter support.
