Aeromines are machines designed by the Space Pirates as a defense measure. They are usually in a group of eight shielded drones aligned in a hexagonal pattern. Aeromines are exclusive to Metroid Prime 3: Corruption. Aeromines are found in Norion, Bryyo, Elysia, and even the G.F.S. Olympus. They were designed by the Space Pirates with a major design flaw, both the shield and weaponry run on the same energy source, meaning each Aeromine can either use its shield or beam, but not both simultaneously. Their main function seems to be blocking certain areas from being easily reached.
Although there are eight of them, Aeromines attack Samus one at a time. By shooting a blue beam, however, they lose their ability to maintain their shield. Because of this, Aeromines seem to attack one at a time to avoid being destroyed all at once. If an enemy is in close proximity, instead of shooting a beam Aeromines will self-destruct for higher damage.
- "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." — Logbook "Aeromine" (Metroid Prime 3: Corruption)
