The Razor-class frigate was a class of frigate used by the Imperial Navy during the Galactic Civil War. In 0 ABY, Lieutenant Pyparr commanded the Razor-class vessel Kreuge's Revenge, which the rebel pilot Luke Skywalker encountered, along with three TIE fighters, in the remote Tertiary Usaita system. Skywalker barely escaped in his starfighter, Y 4, although he was pursued by the Imperials.
The bridge of a Razor-class frigate
The Razor-class frigate was a capital ship reminiscent of an Imperial-class Star Destroyer but with a blockier structure. It featured a hexagonal command tower, which contained the ship's bridge. In turn, the bridge featured a sunken pit for crewmen and multiple trapezoidal viewports with controls beneath. On top of the tower sat a communications tower, with two deflector shield generator domes flanking it. The ship was armed with three dual laser cannons, which were located below the bow, and propelled by sublight engines.

In 0 ABY, over a month after the Battle of Yavin, which marked the Rebel Alliance's first major victory against the Galactic Empire, the Razor-class frigate was in use by the Imperial Navy. At this time in the Galactic Civil War, the rebel pilot Luke Skywalker was assigned to recover Imperial communication logs. After traveling to the remote Tertiary Usaita system in his BTL-S3 Y-wing Starfighter, Y 4, Skywalker was ambushed by the Razor-class frigate Kreuge's Revenge, which was commanded by Lieutenant Pyparr and backed by three TIE/ln space superiority starfighters.
Pyparr contacted Skywalker, informing him that the system was restricted and that his fighter should prepare for inspection. However, the rebel chose to fight for the minute it would take for his droid, R2-D2, to calculate a hyperspace route. Skywalker managed to evade the fighters, even destroying one of them, but then his Y-wing was hit, killing his deflector shields. The frigate itself then started firing on the trespassing starfighter, allowing the TIEs to hit Skywalker's starboard engine.
Just before the rebel vessel would be destroyed, R2-D2 engaged the fighter's hyperdrive, bound for Devaron. On the Kreuge's Revenges bridge, an Imperial ensign desperately ordered other officers to find the escaped craft. However, Pyparr reminded the ensign that the rebel ship had been badly damaged, accurately predicting that Skywalker would be going to the nearest spaceport. The lieutenant then ambushed Skywalker on Devaron, only to be defeated.
The Razor-class frigate first appeared in Jason Fry's 2015 junior novel The Weapon of a Jedi: A Luke Skywalker Adventure. It was first pictured in "The Weapon of a Jedi, Part 1," the first instalment of the novel's comic-book adaptation, which was written by Alec Worley and illustrated by Ruairí Coleman. The comic was included in the German magazine Star Wars - Magazine 19, which was released by Panini Verlag on March 29, 2017.
Since neither the novel nor the comic script specified a design for the Razor-class, illustrator Ruairí Coleman had free reign in creating the vessel's look, although writer Alec Worley did tell him the frigate was around one-fifth the size of a regular Star Destroyer. Considering that the ship would only appear in a few panels, Coleman sought to make it instantly recognizable as an Imperial craft, which is why he gave it a characteristic command tower. The artist admitted on Twitter that the bottom part of the ship looks more like a freighter than a frigate, and that if given the chance to do it again, he would give the vessel a sleeker design with far more weapons emplacements.
