Chapter 1: Building Starships / Alternate Armors

Fortified Hull

Source Starship Operations Manual pg. 21
By reinforcing critical starship systems with extra-thick armor, a starship’s designer can limit catastrophic failures caused by incoming attacks. A starship can incorporate one fortified hull upgrade, which increases the vessel’s Critical Threshold (CT) value by an amount based on the fortified hull’s material and the starship’s size category (for the purpose of this calculation, Tiny = 1, Small = 2, Medium = 3, Large = 4, etc.). A fortified hull is a passive system that requires no PCU to function.
