HistoryCurrent CompositionAlleged PurchasesFacilitiesMarkingsMissiles and RocketsSpellout, Peace Ruby and Peace NetMajor OperationsSee AlsoThe IRIAF came into being when the former Imperial Iranian Air Force (IIAF) was renamed following the Islamic Revolution in Iran, in February 1979. The British publishing company Orbis' Warplane partwork magazine seems to indicate the renaming did not actually take place until after the Iran-Iraq Warhad broken out. 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. Since the Revolution, the exact composition of the IRIAF is hard to determine, but estimates do exist. Many aircraft belonging to the Iraqi Air Force took refuge in Iran during the Persian Gulf Warin 1991, and many were put into service wi...Get price
