The Second Bomb Component is the first acquirable part of the Theronian bomb. Following Aurora Unit 217's activation, the computer calculates a plan to destroy the Elysia Seed. Since Elysia is a gas giant, Samus 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 herself. 217 first requests that Samus find the SkyTown Federation Landing Site to obtain a special upgrade for her gunship, the Ship Grapple.
