The additions below help to prevent unwanted scoundrels from absconding with a starship. Security systems require an operational power core to function, but they consume a negligible amount of PCU. The cost of each option is listed in the table below.
|Name||Cost (In BP)||Source|
|Anti-hacking systems||3||CRB p.300|
|Antipersonnel weapon (heavy)||5 + item level of weapon||CRB p.300|
|Antipersonnel weapon (longarm)||Item level of weapon||CRB p.300|
|Biometric locks||5||CRB p.300|
|Computer countermeasures||Tier of computer||CRB p.300|
|Self-destruct system||5 × size category||CRB p.300|
