Engineering
From Halopedia, the Halo wiki
Engineering is an imortant part of UNSC ships. It provides energy, the ability to move the ship and of course FTL.
The standard Halcyon-Class Cruiser has its engineering section in the middle of the ship. The section covers nearly the entire width of the ship and is the largest single room onboard. It has 6 Nuclear generators that power the ship. The standard Halcyon can still move with only one generator working, howether when all are out, the core becomes unstable and auto-distructs.
At the end of the Battle of Installation 04, the Master Chief caused a manual auto-destruct in the same maner, by using Rocket Launchers to destroy the engines.
