Armor protects a ship from direct-fire weapons (see Type on page 303), deflecting their energy and preventing damage to critical ship systems. It grants an armor bonus to a ship’s AC. Armor’s cost depends on the bonus it grants and the ship’s size category (for the purpose of this calculation, Tiny = 1, Small = 2, Medium = 3, Large = 4, etc.). Armor is a passive system and does not require any PCU to remain functional. It provides protection primarily through mass, which can affect a ship’s maneuverability (making it harder to turn) and make it easier for opponents using tracking weapons to lock on to the ship—these effects are listed in the Special column of the table below.
