SpaceShipTwo Serial Number Two[4] (Tail number: N202VG[2]), previously known as VSS Voyager, is a SpaceShipTwo-class suborbital rocket-powered manned spaceplane. It is the second SpaceShipTwo to be built, and will be used as part of the Virgin Galactic Fleet.

The Spaceship Company is building the second SpaceShipTwo suborbital spaceplane for Virgin Galactic.[5] The craft has yet to be formally named,[5][6] and is commonly referred to as SpaceShipTwo, Serial Number Two.[7][8] There was speculation in 2004 that SpaceShipTwo Serial Number Two would be named VSS Voyager,[9] and this unofficial name has been repeatedly used in media coverage of the ship.[10][11][12]

A US Trademark application in October, 2015 suggests the name to be VSS Unity. [13]

Virgin Galactic expects Serial Number Two to be ready for airborne testing in early 2016.[3]


The manufacture of Serial Number Two began in 2012.[2] The spacecraft's registration, N202VG, was filed in September 2014.[14] As of early November 2014, the build of Serial Number Two was about 90 percent structurally complete, and 65 percent complete overall. As of April 2015, Serial Number Two was approximately 75% complete,[15] and initial ground tests could commence on this craft by the end of 2015.[16] On 21 May 2015, Serial Number Two reached the milestone of bearing the weight of the airframe on its own wheels.[17] It was thought that testing could have begun as early as the summer of 2015.[1][18][19] However, Virgin Galactic founder Richard Branson has since stated that Serial Number Two would be publicly unveiled in February 2016, with flight testing to begin shortly thereafter.[3] This SS2 is scheduled to be unveiled on 19 February 2016.[20]

Serial Number Two will be the second SpaceShipTwo to be completed; the first, VSS Enterprise, was destroyed in a crash in late October 2014.[5][11]

Test flight program[edit]

Serial Number Two will undergo a test regimen similar to VSS Enterprise, then will embark on testing beyond what Enterprise experienced. The test flights are expected to be fewer, as Enterprise has already tested the design's responses under numerous conditions. Testing will start with captive carry, progress to free-flight glide testing, then continue with powered test flights. It is possible that only 2-3 flights under each regime previously tested will be performed, instead of the 5 or 10 that Enterprise performed.[21]
