Space Pirate Assault Skiff
From Wikitroid, the Metroid wiki
Space Pirate Assault Skiffs are modified ATCs equipped with a powerful tribeam cannon to support ground troops. The cannon can easily be overloaded, so the Assault Skiff usually uses hit and run tactics. It is faster than the ATC, but is less durable. You find them while defending the bomb aimed at Elysia's Leviathan. They can do much damage to it. Like the ATCs, their front vent is vulnerable to weapons fire.
