A Missile Expansion as it appears in Metroid Prime 3: Corruption.

A Missile Expansion, Missile Tank or Missile Pod is an expansion that allows Samus Aran to increase the capacity of Missiles Samus can fit into her Missile Launcher. They are often hidden at the end of secret passages. Usually the first one is found out in the open, however. Missiles are always either the first or second item Samus acquires, sometimes switching position with the Morph Ball. They are found in every Metroid game except Metroid Prime Pinball.

They vary in appearance depending on the games they feature in. Usually however, they are grey and rocket shaped, with a purple tip and several 'fins' at the base. In Metroid Prime they are of similar shape but are black and orange. In Metroid Prime 2: Echoes, the Luminoth had created their own design of Missile Expansion, that somewhat resembled a grenade with orange markings. However, It was still compatible with Samus' Missile Launcher. The standard design of expansion found in Prime also appeared in Echoes, though was only available through the Galactic Federation base after fighting the Dark Missile Trooper. Corruption featured a scaled down version of Prime's Tank, but contained within a canister. In Metroid: Other M, they are no longer shaped like Missiles except when in a tank holding the Missile itself, and has a "blue-green" color. In the game, they only add one Missile. In Metroid Samus Returns, they increase capacity by 3, and by 2 in Metroid Dread. Dread also features Missile+ Tanks, which increase the Missile Counter by 10 units.

  • The Metroid II: Return of Samus manual incorrectly states that Missile Pods fully restore Samus's supply of missiles upon acquisition.
  • Although the Echoes variation of Missile Expansions do not appear in Corruption, Missile Ammo in the latter resembles the Expansions in the former.
  • Missile Tanks may have some organic properties, as an X Parasite copied one in Metroid Fusion.
  • Although Echoes has its own design for Missile Expansions, the Dark Missile Trooper when killed will drop a Missile Expansion with the same appearance from Metroid Prime, implying the Missile Launcher was originally meant to be acquired from defeating it.
