There are more than 300 aircraft flying today which are out of production, or nearing the end of their production cycle, and yet still have key roles in civil and military fleet structures throughout the world. This biennial publication describes them in technical detail. Many have been upgraded, mainly through retrofit of avionics and weapons systems, others remain unchanged but have many years of airframe life left. Each entry in this book is illustrated and shows the original specifications, manufacturer, development history and quantity built. The information on each aircraft is then expanded by inclusion of numbers flying today, who owns these aircraft, and details of how they have been upgraded where applicable. This publication is also available on CD-ROM and EIS.
