More strides were made in 1935. Production machinery for aircraft manufacturing arrived from England, France and the Pratt and Whitney Company of the United States. The Shahbaz Aircraft manufacturing plant at Doshan Tappeh was formally inaugurated on September 12, 1936. The plant produced ten Hawker Audex combat aircraft that same year under license. Plans were underway to produce more combat aircraft but the onset of World War Two put a halt to these projects. By the onset of World War Two possessed 122 outdated Hawker series combat aircraft (Audax, Hind and Fury) with only forty of these fit for combat when the Anglo-Soviets invaded in August 1941.
