The Buran spacecraft (Russian: Бура́н, IPA: [bʊˈran], Snowstorm or Blizzard), GRAU index 11F35 K1 was a Soviet orbital vehicle analogous in function and design to the US Space Shuttle and developed by Chief Designer Gleb Lozino-Lozinskiy of RKK Energia. Buran completed one unmanned spaceflight in 1988 and remains the only Soviet space shuttle that was launched into space, as the Buran programme was cancelled in 1993.
