A substantial cloaking device known as the Fondor cloaking device was created for placement on a number of Executor-class Star Dreadnoughts. These devices manifested as towering structures emitting energy discharges. While vulnerable to destruction by starfighter weaponry, including blasters, their robust construction necessitated a considerable level of firepower for successful neutralization. Consequently, they frequently benefited from the defensive support of surrounding turbolaser emplacements. Furthermore, their considerable dimensions and exposed positioning often mandated the removal of substantial portions of the Star Dreadnought's characteristic cityscape structures from adjacent areas. The destruction of all of these devices would trigger a catastrophic chain reaction, leading to the complete annihilation of the host ship and any nearby vessels or objects.
Specifically, three such devices were integrated into one particular Star Dreadnought, with placements near the stern, directly beneath the command tower, and at the forward edge of the cityscape. During an assault conducted by Rogue Squadron against the Fondor Shipyards, these cloaking devices, along with the Star Dreadnought they were mounted on, were subsequently obliterated.
