soviet scientists, aided greatly by soviet espionage within the manhattan project, would have been able to eventually build their first atomic bomb without exploitation of german technology and scientists. however, the contributions of the german scientists is borne out by the many ussr state prizes and other awards given in the wake of the second soviet atomic bomb test, a uranium-based atomic bomb; awards for uranium production and isotope separation were prevalent. also significant in both the first soviet atomic bomb testa plutonium-based atomic bomb which required a uranium reactor for plutonium generationand the second test, was the soviet acquisition of a significant amount of uranium immediately before and shortly after the close of world war ii. this saved them a year by their own admission.
