Sure, but I wouldn't call this "armor holds"...
Again, where are they specifically noted (or lised), and where is specified they do not include armor?
Combat step 5 explanation on page 40 at the bottom. Active defenses refers to 5C and passive defenses refers to 5D.
"If a weapon does score a hit, then it must penetrate first the defensive weapons
and then the passive defenses. Defensive weapons (sandcasters, repulsors and beam
weapons used as missile defense) must be allocated against the hits of specific
batteries. For instance, if a ship has eight laser batteries and has been hit four times
by enemy missiles, the player may allocate two laser batteries against each missile
battery hit, all eight lasers against one of the missile battery hits, or any other
combination which satisfies the player. Passive defenses (nuclear dampers, meson
screens, and configuration) resist each battery that hits. Both defensive weapons
fire and passive defenses are resolved in the same way. Consult the relevant portion
of the weapon's attack table. The number at the intersection of the column corresponding
to the attacking weapon's factor and the defending factor must be rolled
or exceeded on two dice to penetrate the defense. The die roll may be modified as
indicated by the notes on the table. If there is no portion of an attack table for a
defending weapon or passive defense, that defense is useless against that weapon.
Weapons which penetrate the ship's defenses inflict damage on their targets.
Each battery is allowed one roll on one or more damage tables, depending on
weapon type. This roll may be modified by various factors."
So passive defenses do not,
in step 5D, refer to armor - only to nuclear dampers,
meson screens, and configuration. Armor protection is part of Step 5E, where penetration has happened damage inflicted is determined.
