The Subspace Gunship is described as the ultimate weapon of the Subspace Army. Its cannon can fire a blast which 'infinitely rends space' and that can create the effects of the detonation of a Subspace Bomb at great distance. Ganondorf forces the R.O.B.s in the Subspace Bomb Factory to detonate the Subspace Bombs there in order to create a large enough area of Subspace to bring in the Gunship. The Gunship is the largest ship in the game by far, and is commanded by Ganondorf and Bowser.
The Gunship consists of a slender, mostly cylindrical forward half and a thicker back half, the entirety of which is colored gray. Two pointed ends come out of the bottom of the Gunship. The sides of the back end are circular, which is the general shape of the emblem of the Subspace Army. A large number of vertical segments stretch out of the Gunship's core; their purpose is unknown. The front half of the Subspace Gunship is its main cannon, and is fairly simple in design. A thicker, horizontal segment houses five batteries of cannons.
The Gunship is captained from a small platform on its back half. In the cutscene The Great Invasion, Ganondorf and Bowser command it from this platform. It is unknown how their commands are issued, as there apparently is no means of interface with the Gunship itself on this platform.
Ganondorf made the Subspace Bomb factory self-destruct in order to draw this ultimate weapon out from Subspace. It's capable of infinitely rending space, and its firepower is greater than that of any weapon. It exists to draw all of this world into Subspace, but the last-ditch efforts of the fighters might prevent this.
