[Spaceships] Armor Density

No, that's not true. Each system is 5% of the ships total mass. It abstracts volume.

Spacecraft hulls are divided into three sections: the front hull, the central hull, and the rear hull. Each represents one-third of the spacecraft’s total mass (not volume). This need not be taken too literally: the actual shape may be more complex, e.g., “the front hull section” could include forward- facing parts of the vessel that are actually part of multiple different subhulls, pods, or wings.

The front, center, and rear hulls each contain six hull systems numbered [1] to [6]. In addition, two of the three hull sections contain deep- buried systems designated [core]. Each system is a major component. The numbers are used for hit location rolls (see p. 61), while the core systems are similar to the vitals location of a human. Each spacecraft has 20 systems, each 5% of the total mass.
