The Security Ministry Seeker is a variant on the Snark that only targets the Security Ministry. If no Security Ministry exists on the target planet, it will hit some other random building instead. If the Security Ministry has been reduced to 0%, it will still hit the wreckage.
To build a Security Ministry Seeker you first need a level 20 Munitions Lab.
Playing Note: This ship is a key ship when attempting to attack a planet followed with a spy assault since a completely damaged Security Ministry will no longer provide any bonus to the defending spies. It will also allow the ships carrying incoming spies to get through without being detected and captured automatically.
