The documents containing evidence of Motor Sich Corporation's trading with Iranian companies, which were sanctioned by the National Security and Defense Council in March, were found by law enforcement officers in the office of former Motor Sich president Bohuslaev. These companies are associated with Iran's state military industry and are involved in the development of Shahed-171 and Shahed-136, which the Russian army is currently using to shell Ukrainian cities. Motor Sich sold dual-use goods to Iran, including AI-9 and TV3-117 aircraft engines, which are installed on both small transport aircraft and military helicopters, such as the Ka-52 used by Russia in its war against Ukraine.
