Subspace Gunship

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 a Subspace Bomb's detonation 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.

In the Adventure Mode: The Subspace Emissary, Ganondorf and Bowser test its power on an arbitrary area of water. The Halberd moves in to attack the Gunship but is destroyed. In the end, the Gunship is destroyed by Kirby on the Dragoon, thus foiling Tabuu's attempts at invasion. The Gunship is seen exclusively in the cutscene The Great Invasion.
