The PAC JF-17 Thunder, or CAC FC-1 Xiaolong, 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. It was designed to replace the A-5C, F-7P/PG, Mirage III, and Mirage V combat aircraft in the Pakistan Air Force. The JF-17 can be used for multiple roles, including interception, ground attack, anti-ship, and aerial reconnaissance. 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 Klimov 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 at half the cost. The PAF inducted its first JF-17 squadron in February 2010. In 2015 Pakistan produced 16 JF-17s. As of 2016, Pakistan is believed to have the capacity to produce 25 JF-17 per year. 58% of the airframe is Pakistani and 42% Chinese/Russian-origin. As of December 2016 Pakistan Aeronautical Complex has manufactured 70 jets in the country for use by the Pakistan Air Force of the Block 1 type, and 33 jets of the Block 2 type.
