The Buran programme (Russian: Буран, IPA: [bʊˈran], lit. 'Snowstorm' or 'Blizzard') was a Soviet and later Russian reusable spacecraft project to develop the Energia-Buran system, officially known as the Reusable Space System "Buran" (Многоразовая Космическая Система «Буран»), that formally began in 1976 and was suspended in 1993. In addition to being the designation for the whole Soviet/Russian reusable spacecraft project, Buran was also the name given to orbiter 1K, which completed one uncrewed spaceflight in 1988 and was the only Soviet reusable spacecraft to be launched into space. The Buran orbiters used the expendable Energia rocket as a launch vehicle. The Buran programme was started by the Soviet Union as a response to the United States Space Shuttle programme. The latter's unclassified nature was a boon for the Soviets and resulted in many superficial and functional similarities between American and Soviet shuttle designs. Although the Buran orbiter was similar in appearance to NASA's Space Shuttle orbiter, and could similarly operate as a re-entry spaceplane, its final internal and functional design was different. For example, the main engines during launch were on the Energia rocket and were not taken into orbit by the spacecraft. Smaller rocket engines on the craft's body provided propulsion in orbit and de-orbital burns, similar to the Space Shuttle's OMS pods. Unlike the Space Shuttle whose first orbital spaceflight was accomplished in April 1981, Buran, whose first and only spaceflight occurred in November 1988, had a capability of flying uncrewed missions, as well as performing fully automated landings. The project was the largest and the most expensive in the history of Soviet space exploration.
