High Quality Content by WIKIPEDIA articles! PPTS (Prospective Piloted Transport System or Perspektivnaya Pilotiruemaya Transportnaya Sistema), unofficially called Rus, is a project being undertaken by the Russian Federal Space Agency to develop a new-generation manned spacecraft. Its official name is Pilotiruemyi Transportny Korabl Novogo Pokoleniya or PTK NP meaning New Generation Piloted Transport Ship. The goal of the project is to develop a new-generation spacecraft to replace the current Soyuz which was developed by the former Soviet Union. The PPTS project was started following the failed plans by Russia to co-develop Crew Space Transportation System (CSTS, until middle 2006 named ACTS) with Europe. Following this the Russian Federal Space Agency ordered the local space industry to finalize proposals for the new manned spacecraft.
