"This artist's rendering depicts the McDonnell Douglas X-33 proposal. this was to serve as a technology demonstrator of a Single-Stage-To-Orbit (SSTO) Reusable Launch Vehicle (RLV). McDonnell Douglas submitted a vertical landing configuration design which used liquid oxygen/hydrogen engines. NASA considered design submissions from Rockwell, Lockheed Martin, and McDonnell Douglas. NASA selected Lockheed Martin's X-33 design on 2 July 1996. The RLV technology program was a cooperative agreement between NASA and industry. The goal of the RLV technology program was to produce significant reductions in the cost of access to space, and to promote the creation and delivery of new space services and other activities that would have improve U.S. economic competitiveness."
