The PAC JF-17 Thunder (Urdu: جے ایف-١٧ گرج), or CAC FC-1 Xiaolong (Fierce Dragon; Chinese: 枭龙; pinyin: Xiāo Lóng), is a lightweight, single-engine, multi-role combat aircraft developed jointly by the Pakistan Aeronautical Complex (PAC) and the Chengdu Aircraft Corporation (CAC) of China. The JF-17 can be used for aerial reconnaissance, ground attack and aircraft interception. Its designation "JF-17" by Pakistan is short for "Joint Fighter-17", while the designation and name "FC-1 Xiaolong" by China means "Fighter China-1 Fierce Dragon".
The JF-17 can deploy diverse ordnance, including air-to-air and air-to-surface missiles, and a 23 mm GSh-23-2 twin-barrel autocannon. Powered by a Guizhou WS-13 or RD-93 afterburning turbofan it has a top speed of Mach 1.6. The JF-17 is to become the backbone of the Pakistan Air Force (PAF), complementing the General Dynamics F-16 Fighting Falcon whose performance it roughly matches, at half the cost. The PAF inducted its first JF-17 squadron in February 2010 and five years later 54 units were in service, and 96 units were on order, to be delivered by the end of 2018.
