The state of the military industry can serve as an indicator of the level of economic and cultural development of the country. How successfully did the Russian Empire supply its army with rifles, guns, ammunition? What caused the failures in this area? To what extent was it possible to compensate for the lack of allied supplies? Finding an answer to these questions is still a research task. It is necessary to separate precisely established data, facts substantiated by sources from contrived constructions, to trace the real fate of large-scale plans and projects, the interaction of state structures and public initiative independent of the authorities. The development of the military industry is considered in the book in connection with political and strategic decisions, in the light of the spiritual traditions of the Russian monarchy. The book is intended for specialists in the field of military and economic history, as well as for anyone interested in the history of the Russian armed forces, the causes of the power crisis on the eve of 1917.
