Serenity is a fictional spaceship originally featured in the science fiction television series Firefly. It has also appeared in the comic book series Serenity: Those Left Behind and the film Serenity.
The ship, which is designated a 03 Firefly-class, fits the profile of a light freighter, having a cargo area equivalent to about six to nine semis. The photon-reaction drive in the bulbous rear section of the ship lights up when accelerating, resembling a firefly, hence the class moniker. The engine nacelles can rotate down like a VTOL aircraft. Whenever the ship lands, her wings fold down like the wings of a bird coming to rest. The aft of the ship is outfitted with extenders beside and below the photon-reaction drive to ease the turbulence of lift-off and atmospheric reentry. As she is a run-of-the-mill civilian cargo vessel, Serenity has no weapons or defenses beyond the guile and skill of her crew.
