Orel (Russian: Орёл, lit. 'Eagle') or Oryol, formerly Federation (Russian: Федерация, romanized: Federatsiya), and PPTS (Russian: Перспективная Пилотируемая Транспортная Система, romanized: Perspektivnaya Pilotiruemaya Transportnaya Sistema, lit. 'Prospective Piloted Transport System'), is a project by Roscosmos to develop a new-generation, partially reusable crewed spacecraft.
Until 2016, the official name was (Russian: Пилотируемый Транспортный Корабль Нового Поколения, lit. 'New Generation Piloted Transport Ship') or PTK NP. The goal of the project is to develop a next-generation spacecraft to replace the Soyuz spacecraft developed by the former Soviet Union to support low Earth orbit and lunar operations. It is similar in function to the US Orion or Commercial Crew Development spacecraft.
