The secondary command processors are computer components aboard a Federation starship that are necessary to carry out the self-destruct sequence. These processors are located on deck 12 of an Intrepid-class starship.

She was thus ultimately able to prevent Captain Kathryn Janeway from initiating the auto-destruct when the Kazon-Nistrim overwhelmed Voyager's defenses. (VOY: "Basics, Part I")
