Rocketplane-Kistler was awarded a COTS contract in 2006. The company was formed in 2006 in Oklahoma when Rocketplane Limited, Inc. acquired Kistler Aerospace.
Rocketplane-Kistler began missing financial and technical milestones and the contract with NASA was terminated by NASA in October 2007. Conditions continued to deteriorate and Rocketplane closed its doors in 2009, and filed for bankruptcy on 15 June 2011.
The primary product of Rocketplane was to have been a fully reusable two stage launch vehicle, the Kistler K-1. It would have been able to launch to low Earth orbit and deliver supplies to the International Space Station. One version of the craft was found in an Oklahoma City scrap yard.
