Aeromines suffer from a design flaw--their shield- and beam-weapon units use the same power source, allowing only one to function at a time. This exposes the unit to damage when it fires at enemies. Aeromines were originally designed to take the role of sentry for Space Pirates, but have since been put to use in combat as well. Because of the initial design flaw, these units do not pose much of a threat. After the executions of the first design team, the new pirate designers swore to correct this flaw with great haste.
