Overview

The Buran orbital vehicle program was developed in response to the U.S. Space Shuttle program, which in the 1980s raised considerable concerns among the Soviet military and especially Defense Minister Dmitriy Ustinov

, the Soviet military became suspicious that it could be used for military purposes, due to its enormous payload, several times that of previous U.S. spaceships. The Soviet government asked the Russian TsNIIMash

 (ЦНИИМАШ, Central Institute of Machine-building, a major player in defense analysis) for an expert opinion. Institute director, Yuri Mozzhorin, recalls that for a long time the institute could not envisage a civilian payload large enough to require a vehicle of that capacity. Based on this, as well as on US profitability analyses of that time, which showed that the Space Shuttle would be economically efficient only with a large number of launches (one every week or so), Mozzhorin concluded that the vehicle had a military purpose, although he was unable to say exactly what. The Soviet program was further boosted after Defense Minister Ustinov received a report from analysts showing that, at least in theory, the Space Shuttle could be used to deploy nuclear bombs over Soviet territory. Chertok recounts that Ustinov was so worried by the possibility that he made the Soviet response program a top priority.

Officially, the Buran spacecraft was designed for the delivery to orbit and return to Earth of spacecraft, cosmonauts, and supplies. Both Chertok and Gleb Lozino-Lozinskiy

 rocket, which to this day remains the heaviest rocket running on liquid fuel. Unlike the Space Shuttle, which is propelled by a combination of solid boosters and the Shuttle's own liquid-fuel engines fueled from a large fuel tank, the Energia-Buran system used only thrust from the rocket's four RD liquid-fuel engines developed by Valentin Glushko. From the very beginning Buran was intended to be used in both fully automatic and manual mode. Although the program accumulated a several-years delay, Buran remained the only space shuttle to ever perform an unmanned flight in fully automatic mode until 22 April 2010 when the US Air Force launched its Boeing X-37

 spaceplane. 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 revolutions around the Earth, ODU (engine control system) engines fired automatically to begin the descent into the atmosphere. Exactly 206 minutes into the mission, the Buran orbiter landed, having lost only five of its 38,000 thermal tiles over the course of the flight. The automated landing took place on a runway at Baikonur Cosmodrome where, despite a lateral wind speed of 61.2 kilometres per hour (38 mph), it landed only 3 metres (9.8 ft) laterally and 10 metres (32.8 ft) longitudinally from the target mark. The unmanned flight was the first time that a spacecraft of this size and complexity had been launched, completed maneuvers in orbit, re-entered the atmosphere, and landed under automatic guidance.

Projected flights

In 1989, it was projected that Buran would have an unmanned second flight in 1993, with a duration of 15–20 days. Due to the cancellation of the project after the dissolution of the Soviet Union
