Mir

The Mir is a Russian Siege Cruiser (slightly bigger than the USS George W. Bush), disguised as a space station used by the Beleninsk Pact as a weaponised spacecraft against the invading Space Coalition forces and later the Immortal Armada.

Mir had a controllable energy particle weapon as its main weapon, and was seen firing at full capacity emitting a light blue beam at a Star Destroyer while at Earth's orbit and over the Eiserne Zitadelle. the Mir fires the beam again at lower strength emitting a light purple beam while fighting alongside the Space Battleship Yamato.

The Mir later participated in the Battle for the Multiverse and it was known for destroying the axial superlaser of the Deathshead; the flagship of the Immortal Armada.
