Samus Aran, dispatched by the Federation to investigate the Space Pirate presence in the Bermuda System, first discovered a hint at a 'strategic weapon' at the end of M07: Cauldron. It is the setting of the last mission, M22: Convergence, in which the Federation Force must infiltrate the Doomseye and disable its protection shield, so it may be destroyed. The Pirates seek to use Doomseye to take their revenge against the Galactic Federation after their organization was weakened following the loss of Phazon during Metroid Prime 3: Corruption. Under the control of Master Brain, it is the main antagonist of Metroid Prime: Federation Force and the final location.
The Doomseye is a Space Pirate battleship and their 'strategic weapon' in the Bermuda System operation.
