This "new" Iranian air force largely inherited the equipment and structure of the former IIAF, even losing most of its leading officers in the course of post-revolutionary chaos, as well as due to the prosecution of those considered as loyal to the Shah, pro-U.S. or elsewhere by the new government in Tehran. Due to strained relations with the west, Iran had to procure new equipment from Brazil, Russia and the PeopleRepublic of China.
