Tier 1b is the suborbital commercial human spaceflight platform being developed by The Spaceship Company (TSC), originally a joint venture of Scaled Composites and Virgin Galactic.[citation needed]

The Tier 1b program was intended to be an evolutionary development of Tier One, the Ansari X-Prize-winning entry in the 2004 spaceflight demonstration contest held by the X-Prize Foundation.[citation needed]

Tier 1b's primary hardware components are the White Knight Two carrier aircraft and the SpaceShipTwo suborbital spaceplane,[citation needed] the latter of which was, as of April 2013, expected to begin flying space tourists to suborbital altitudes in 2014.[1][2][3] A number of earlier projections for flights to space-altitude were made in the 2000s and early 2010s.
