Activator core

The activator core was a crucial part of at the very least a Cybercarrier.

History
While destroying the Cybercarrier recovered by Ashad, Ko Sharmus planted an explosive on the ship's activator core. Ko Sharmus informed his companions that when the activator core blew, it would set off a chain reaction throughout the entire ship. Shortly thereafter, the explosives armed themselves and detonated, destroying the Cybercarrier and everything on it. (TV: The Timeless Children)
