The Narcissus was a shuttlecraft and lifeboat for the Weyland-Yutani commercial hauler USCSS Nostromo. The Narcissus weighed 48 metric tonnes and had a range of 13 parsecs. The Narcissus was 16.3 meters in length, 19.7 meters wide and 7.5 meters in height.
In 2122, the Nostromo had been intruded by a Xenomorph and began to kill the Nostromo's crew members one by one. Warrant Officer Ellen Ripley sets off the Nostromo's self-destruct system as an attempt to kill the creature, she along with her pet cat Jones boards the Narcissus to escape the Nostromo just moments before its destruction. Unknown by her that the creature had also snuck onboard the shuttlecraft by camouflaging itself in a small crevice, but Ripley finally managed to kill it by blowing it out the airlock and igniting it with the engines. Ripley proceeded to activate the shuttlecraft's auto pilot and afterwards entered hypersleep with her cat, Jonesy.
The Narcissus automatically shut its entire system down and reserved its remaining power in order to support Ripley's cryo chamber. It would remain adrift in space for the next 57 years until it was recovered by the crew of the Tripast Salvage, both Ripley and Jonesy are rescued from their long period of hypersleep and are immediately transferred to the Gateway Station for medical care.
