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

The only orbital launch of a Buran-class orbiter, 1K1 occurred at 03:00:02 UTC on 15 November 1988 from Baikonur Cosmodrome launch pad 110/37. Buran was lifted into space, on an uncrewed mission, by the specially designed Energia rocket. The automated launch sequence performed as specified, and the Energia rocket lifted the vehicle into a temporary orbit before the orbiter separated as programmed. After boosting itself to a higher orbit and completing two orbits around the Earth, the ODU engines fired automatically to begin the descent into the atmosphere, return to the launch site, and horizontal landing on a runway.

After making an automated approach to Site 251, Buran touched down under its own control at 06:24:42 UTC and came to a stop at 06:25:24, 206 minutes after launch. Despite a lateral wind speed of 61.2 kilometres per hour (38.0 mph), Buran landed only 3 metres (9.8 ft) laterally and 10 metres (33 ft) longitudinally from the target mark. It was the first spaceplane to perform an uncrewed flight, including landing in fully automatic mode. It was later found that Buran had lost only eight of its 38,000 thermal tiles over the course of its flight.
