Starship spines are a combination of rigid spikes, jagged blades, and long spines that can fend off nearby starships and creatures. When a starship outfitted with starship spines is rammed by another vessel (Starfinder Starship Operations Manual pages 16–17) or struck by an attack whose maximum range is 1 hex, that vessel provokes a free attack with the spines from the starship. The spines are a starship weapon that require no mount; they can attack any arc, can’t be used to make any other attacks, and deal 5d4 damage. Mk 3 starship spines can only be installed on Medium or larger starships.
