Tier 1b's SpaceShipTwo spaceplane (central fuselage) attached to the White Knight Two carrier aircraft.

Tier 1b was the Scaled Composites internal company name of a mid-2000s program to develop a nine-passenger suborbital commercial human spaceflight platform.[1][2]

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

The principle hardware envisioned to be developed under the Tier 1b program were the White Knight Two carrier aircraft and the SpaceShipTwo suborbital spaceplane.[1][clarification needed]
