The JF-17 was primarily developed to meet the requirements of the Pakistan Air Force for a low-cost[9] multi-role combat aircraft as an inexpensive replacement for its large fleet of aging Nanchang A-5 bombers, Chengdu F-7 interceptors and Dassault Mirage III/5 fighters. It was also to have export potential to air forces of developing countries as a cost-effective alternative to more expensive Western-origin fighters.
