I wonder about the self-destruct system of the Honorverse ships. What exactly happens during a self-destruct? Is it charges set up all over the ship or some mechanism akin to a matter, anti-matter mix, which would result in a complete destruction. Charges may not result in a complete destruction. Anyone know of the details? I can't seem to find any reference.
Star Trek wiki wrote:Constitution-class starships, the captain and two senior officers were required to initiate the destruct sequence, using the following, concurrent codes.
Each officer would state their name, rank and corresponding code:
1. "Destruct sequence 1, code 1-1 A."
2. "Destruct sequence 2, code 1-1 A-2B."
3. "Destruct sequence 3, code 1 B-2B-3."
The computer would then reply:
The countdown begins (2285)
"Destruct sequence completed and engaged. Awaiting final code for (time interval) countdown."
The commanding officer would then state:
"Code zero zero zero. Destruct. Zero."
The sequence could be aborted at any time until T-minus five seconds by the captain or highest-ranking officer, with the command "Code 1-2-3-continuity, abort destruct order." Beyond that, the destruct order could not be cancelled.
Galaxy class starships were also equipped with auto-destruct systems. There were two systems used for auto-destruct on such vessels. The first, and primary method involved the shutting down of antimatter containment, plus an overload of the warp core. The resulting explosion was estimated to be equivalent to the detonation of 1,500 photon torpedoes.
The secondary method involved the setting off of charges spread throughout the ship, which was estimated to be equivalent to the detonation of 1,000 photon torpedoes. This secondary method was used on the saucer section during separated flight operations or throughout the ship when the primary auto-destruct system was offline. (TNG reference: Technical Manual)
To activate the auto destruct, the two senior officers - usually the Captain and First Officer - would touch a computer panel and identify themselves to the main computer. The Captain would instruct the computer to set the auto-destruct. The First Officer would then be asked if he or she agreed with the decision. Once that agreement was given, the computer would begin the auto-destruct sequence. The auto-destruct could be canceled at any point prior to T minus 0. The computer would check to see who was on board, and could accept auto-destruct commands down to the level of operations manager. Originally, the computer was set to give a five minute countdown, but a later modification was made allowing the countdown to be modified.
