Buran was the first spaceplane to be produced as part of the Soviet/Russian Buran programme. It is also known as "Shuttle 1.01". Besides describing the first operational Soviet/Russian shuttle orbiter, "Buran" was also the designation for the whole Soviet/Russian spaceplane project and its orbiters, which were known as "Buran-class spaceplanes".

Buran completed one unmanned spaceflight in 1988, and was destroyed in 2002 when the hangar it was stored in collapsed. It remains the only Soviet reusable spacecraft to be launched into space. The Buran-class orbiters used the expendable Energia rocket, a class of super heavy-lift launch vehicle.
