The First Bomb Component is the first acquirable part of the Theronian Bomb in Metroid Prime 3: Corruption, though it is the last to actually be seen. It is the only bomb component that can be accessed without the use of the Seeker Missiles.

Following Aurora Unit 217's vaccination, the supercomputer calculates a plan to destroy the Elysia Seed. Since Elysia is a gas giant, Samus Aran will not be able to destroy the Leviathan Shield Generators underneath the dense clouds. Instead, she must assemble the Theronian Bomb, a thermonuclear explosive device that will destroy the Leviathan Shield itself. However, Samus cannot lift the components unaided. 217 first requests that Samus find the SkyTown Federation Landing Site to obtain a special upgrade for her Gunship, the Ship Grapple Beam.

Upon acquisition of the upgrade, 217 provides Samus the coordinates of each component. The first is located in the Turbine Chamber. Samus encounters the bottom of the component, acting as a turbine, when she first passes through the bottom floor of the chamber, and finds it being held by two electromagnetic cradle arms. She destroys the cables holding the spike and it splits open, allowing her to move on. Samus later enters the top floor and attempts to begin releasing the component, but a Berserker Lord ambushes her and she is forced to battle it.

After the Berserker Lord's death, four Spinners encircling the component activate. Samus's use of them lifts locks on the floor, and activates a control terminal in the room. Samus interfaces with it, and the floor releases the bomb part, allowing her to call her Gunship to collect the component.

In the original version of the game, the Spinners remain active for the duration of the fight, but the Berserker Lord will reset Samus's progress the moment one of the locks is released. This element is removed in later releases, as it will occasionally cause minor glitches to occur.
