The history of the Iranian Air Force, currently known as the Islamic Republic of Iran Air Force (IRIAF), can be divided into two phases - before the Islamic Revolution (1978-79) and after it. The origins of the force lie in the Imperial Iranian Air Force (IIAF), which became operation with its first fully trained pilots in 1925\. Until World War Two, the IIAF inventory consisted of entirely od European aircraft, however, following the British and Soviet invasion of Iran, the IIAF's bases were occupied and all aircraft destroyed. In this book, Babak Taghvaee examines the inventory of the IIAF during both world wars.
