 Russian Defense Minister Sergei Shoigu visited arms factories in Russia's Chelyabinsk and Kirov regions, the ministry said on March 28. According to the ministry, Shoigu inspected facilities directly involved in the production of military produce, mainly large-caliber ammunition, for use in what Russia calls its special military operation in Ukraine. The Defense Minister was shown automated production lines making artillery, tank and mortar shells of various calibers and unguided aircraft missiles, as well as areas for quality control of products. During the trip, Shoigu was reportedly told that arms production will be increased seven or eight times by the end of the year.
