An Autobot spaceship appearing in Transformers: Dark of the Moon. It is described as having brought the second wave of Autobots to Earth. The Xantium is kept at the Kennedy Space Center in Florida where it is linked to a decommissioned space shuttle so the human military can have some control over it. It is tended to by the Wreckers under the command of Robert Epps. Optimus Prime and Ratchet use it to travel to the Moon to retrieve Sentinel Prime and five Space Bridge pillars from the remains of the Ark. When the Autobots are exiled from Earth, it is used to leave, but it is destroyed by Starscream before it can leave the atmosphere, apparently killing the Autobots. It is later revealed that the Autobots were in the first booster rocket to separate from the ship and faked their own deaths to catch the Decepticons off-guard.
