Sharashkas (singular: Russian: шара́шка, [ʂɐˈraʂkə]; sometimes sharaga, sharazhka) were secret research and development laboratories operating from 1930 to the 1950s within the Soviet Gulag labor camp system, as well as in other facilities under the supervision of the Soviet secret service. Formally various secret R&D facilities were called "special design bureau" Russian: особое конструкторское бюро, ОКБ and similar terms. Etymologically, the word sharashka derives from a Russian slang expression sharashkina kontora, ("Sharashka's office"), an ironic, derogatory term to denote a poorly-organized, impromptu, or bluffing organization, which in its turn comes from the criminal argot term sharaga (шарага) for a band of thieves, hoodlums, etc.[1])
The scientists and engineers at a sharashka were prisoners picked by the Soviet government from various camps and prisons and assigned to work on scientific and technological problems. Living conditions were usually much better than in an average taiga camp, mostly because of the absence of hard labor.
The results of the research in sharashkas were usually published (if published at all) under the names of prominent Soviet scientists without credit given to the real researchers, whose names frequently have been forgotten.[citation needed] Some of the scientists and engineers imprisoned in sharashkas were released during and after World War II (1939–1945) to continue independent careers; some became world-renowned.
