The USM (United Systems Military) Auriga is a fictional spaceship depicted in the fourth installment of the Alien quadrilogy, Alien: Resurrection and is by far the largest vessel depicted in the Alien series. A large, well-equipped military vessel, the Auriga is primarily used for illegal medical research and biological weapons development. It has a small crew of medical scientists and security personnel, and is commanded by the corrupt USM General, Ramón Perez.

The vast majority of the film is set on the Auriga, where the long-dead Ellen Ripley has been cloned from frozen DNA taken from the prison planet Fiorina 161 in Alien³, along with the embryonic Xenomorph Queen growing inside her. The Auriga's scientists manage to successfully extract the Queen, and the Ripley clone quickly recovers, having somehow retained all her former memories and intelligence. However, the Alien drones being kept for study soon escape, slaughtering the ship's guards and scientists, including General Perez and his aides.

The rest of the film details the exploits of Ripley and a motley crew of renegades (including the good-intentioned female android, Call) as they attempt to escape with their lives. Many of them are killed in the process, but Ripley, Call and a few others manage to escape on board the renegades' transport ship, the Betty.

The Auriga is destroyed when Call programs its engine controls to send it into a collision course with Earth. The impact obliterates the ship and all the Aliens on board.
