VMS Eve[1] (Tail Number: N348MS[2]) is a carrier mothership for Virgin Galactic and launch platform for Scaled Composites SpaceShipTwo-based Virgin SpaceShips.

VMS Eve is the first, and so far only, WhiteKnightTwo, built by Scaled Composites for Virgin Galactic. The "VMS" prefix stands for "Virgin Mothership".[3]

Public Launch

VMS Eve's nose art

The aircraft was named after Evette Branson, the mother of Richard Branson, Chairman of the Virgin Group. The jet plane has nose art of a blond woman holding the Virgin Galactic corporate flag.[4] The image is based on how Evette Branson looked when she was younger and is called Galactic Girl.[5] The aircraft was officially launched on Monday, July 28, 2008, in Mojave, California, USA, at the Mojave Spaceport, home of Scaled Composites. On December 12, 2008, the aircraft performed first taxi tests,[6] and a week later the maiden flight.[7] Eve will be used in the Virgin Galactic testflight program, preceding entry into commercial usage.[8]

It is the largest all composite aircraft ever constructed and has the longest single-piece composite aircraft part: a 140 ft (43 m) long wingspar.[9] Burt Rutan has dismissed fears that pressurization cycles might induce fatigue failure in the composite structure.[10] Richard Branson has also announced that it will be highly fuel efficient.[11]


Flight test program

The initial flight tests were planned to begin in early September 2008[12][13][14] but they were delayed.[15] The flight tests were expected to be complete by September, 2009.[16]

  • December 12, 2008 -- WhiteKnightTwo did a low speed taxi trial at Mojave.[17]
  • December 16, 2008 -- WhiteKnightTwo did a high speed taxi trial at Mojave.[18]
