Unidentified Executor-class Star Dreadnought

This prototype Imperial Executor-class Star Dreadnought was fitted with multiple cloaking devices and underwent construction over Fondor in 3 ABY.

History
The vessel was made as part of a ruse by Emperor Palpatine to give the Rebel Alliance an easy victory that would increase their daring before the climactic Battle of Endor.

The shipyard it was berthed in was surrounded by an extensive network of space stations fitted with deflector shield generators. The initial Rebel strike team blasted their way through one of the stations, with an unmanned GR-75 medium transport ramming the dock's primary control center.

Having fought their way through the protective shielding system, the Rebel fighters, led by Wedge Antilles, managed to knock out three main cloaking devices on the unfinished Star Dreadnought, which caused it to explode.

In reality, Palpatine orchestrated the rebels destruction of the prototype star destroyer in order to get them overconfident enough to end up walking into his trap.

Although the prototype was destroyed, the project nonetheless brought a completed version in the form of the Terror.

Armament
The vessel was armed with a number of turbolaser towers that provided defense during its construction. Though the tower defenses could not prevent an assault on the exposed cloaking devices, they made the gauntlet very dangerous for attacking Rebel fighters. The turrets could easily target starfighters who flew too high above the Dreadnought's surface. Like the Terror, It also possessed three cloaking devices that allow the ship to become invisible. The cloaking devices, however, were connected to the power generator, which makes them a crippling weakness to the ship should all of them be destroyed, resulting in its destruction, as Rogue Squadron demonstrated during its mission.
