SpaceShip III (SS3, also with Roman numeral:SSIII; formerlySpaceShipThree) was a planned class ofspaceplanes byVirgin Galactic to followSpaceShipTwo. It was first teased on the Virgin GalacticTwitter account on 25 February 2021 announcing the rollout of the first SpaceShip III plane on 30 March 2021.[1]
By June 2024, development of the two SpaceShip III vehicles, VSSImagine and VSSInspire was canceled, with the intention of using the vehicles for ground testing and development for the successorDelta-class spacecraft.[2] Ultimately, no example of a SpaceShip III vehicle was ever completed or flown in any way (i.e. no captive carry flight, no glide flight, no powered flight nor any other type of flight).
The purpose originally proposed for SpaceShipThree in 2005 was for commercialorbital spaceflight, as part of a program called "Tier 2" byBurt Rutan founder ofScaled Composites.[3][4]
By 2008, Scaled Composites had reduced those plans and articulated a conceptual design wherein the SpaceShipThree vehicles were to be used for transportation throughpoint-to-point suborbital spaceflight traveling outside theatmosphere with the spacecrafts providing, for example, a two-hour trip on theKangaroo Route (fromLondon toSydney orMelbourne).[5]
Scaled was sold toNorthrop Grumman in 2007,[6] and references to further work on a conceptual Scaled SS3 ended at some point afterwards from Scaled. Scaled was realigned by Northrop Grumman in 2015 as a research unit.[7] Virgin Galactic acquired full control ofThe Spaceship Company in 2012, the manufacturer of SS2.[8] The technology was built upon the base technology owned byMojave Aerospace Ventures ofPaul Allen, originally licensed in 2004.[9][10] As Allen died in 2018,[11] subsequent space activities of theVulcan Group went inactive.
By 2016,Richard Branson was still planning to have a point-to-point sub-orbital spaceliner follow-up to SpaceShipTwo, forVirgin Galactic andThe Spaceship Company.[12]
The SpaceShip III vehicle concept was revised to provide just a few minutes of weightlessness and views for space tourists for Virgin Galactic, and was meant to be a production version ofSpaceShipTwo,[13] with improved maintenance and flight rate performance. It did not have point to point transportation capabilities as previously envisioned in 2016.[12]
In early 2021, Virgin Galactic teased an upcoming vehicle on their Twitter account with the name shown in stylized font as "SPACESHIP 3".[1]
The first Spaceship III, VSSImagine, was announced on 25 February 2021 and was rolled out on 30 March 2021. On that occasion, it was indicated there was ground testing to be done before glide test flights could commence, no earlier than the summer of 2021.[13]Imagine was one of two SpaceShip III class spacecraft on order by Virgin Galactic, the second being VSSInspire.[14]
