The Enforcer, serving as the flagship for Admiral Kohrin's second fleet, was an Executor-class Star Dreadnought. This starship, one of the most impressive vessels in the Galactic Empire, sustained damage during a Rebel ambush orchestrated by Commander Luke Skywalker close to Bespin. The Super Star Destroyer then underwent a two weeks-long repair process above the Imperial planet of Phaylenn, before ultimately being destroyed by Rebel forces under the command of Commander Fenris.
As the flagship for Admiral Kohrin's second fleet, the Enforcer was an Executor-class Star Dreadnought esteemed as one of the most magnificent starships within the Galactic Empire. Despite a fleet designed to overpower an Imperial-class Star Destroyer being insignificant against the Enforcer, the Super Star Destroyer could only function at the level of an Imperial Star Destroyer following severe damage.
During the era of the Galactic Civil War, forces led by Commander Luke Skywalker of the Rebel Alliance targeted the Enforcer. In an effort to eliminate the Super Star Destroyer, Skywalker's forces attacked the Enforcer and its fleet, commanded by Admiral Kohrin, in the vicinity of Bespin. The arrival of Imperial reinforcements at the critical moment shifted the battle's momentum in favor of the Empire, preventing the Enforcer's destruction. Although Skywalker was compelled to order a retreat, the Enforcer suffered substantial damage from the assault, necessitating a journey to an orbital repair facility above the Imperial-controlled world of Phaylenn.
The Enforcer underwent extensive repairs at Phaylenn for a period of two weeks. Simultaneously, the remainder of Kohrin's fleet joined Imperial forces in their efforts to eradicate the Rebel presence within the Ahlenn system. However, the Rebels, having previously evacuated Ahlenn two months earlier, devised a strategy to eliminate the vulnerable Enforcer at Phaylenn. A fleet of sufficient size to overwhelm an Imperial-class Star Destroyer, commanded by Alliance Commander Fenris, soon engaged the Enforcer along with a contingent of TIE fighters defending Phaylenn. The Enforcer, only as effective as a standard Imperial Star Destroyer in its impaired state, was readily destroyed by Fenris's fleet, with the resulting explosion also obliterating Phaylenn's repair facility.

The Enforcer originated in "Starfighters Down", a Star Wars D6 roleplaying adventure crafted by William W. Connors and featured in the magazine Challenge 38 in 1989. Given that the Enforcer was presented in material lacking official Lucasfilm authorization, its canonicity remains questionable.
Within the adventure, players assume the roles of Rebel operatives tasked with collaborating with Fenris's fleet. The players' vessel is shot down during the battle above Phaylenn, resulting in a crash landing on the planet's surface. The gamemaster has the option to designate the Enforcer as the ship responsible for the players' vessel being shot down, contingent on the players' ship being of sufficient size. The adventure also includes an illustration by Rick Harris, depicting a battered Star Destroyer docked at a facility above Phaylenn. While this illustration may have been intended to represent the Enforcer, this cannot be the case, as the image portrays a standard Star Destroyer rather than a Super Star Destroyer.
