The Joint Fighter-17 (JF-17) Thunder multi-role fighter was jointly developed by China and Pakistan. Most of the development was carried out in China by Chengdu, however development costs were split equally. It was reported that Russian Mikoyan design bureau provided some assistance in development of this aircraft, which started in 1999. Aircraft made it's maiden flight in 2003. Official Chinese designation is the Fighter China-1 or FC-1 Xiaolong (Fiece Dragon). First fighters were delivered to Pakistan in 2007 - 2008. A further order for 42 was signed in 2009. It is speculated that total requirement of the Pakistani Air Force is for 250 fighters. This multi-role aircraft is also proposed for developing countries as a low-cost replacement, for their ageing types. Recently Azerbaijan ordered 26 of these fighters.

   It is worth mentioning that the FC-1 traces it's origins to the Super-7 programme. It was a joint Chengdu-Grumman development project to upgrade the Chinese J-7 fighter. This programme was cancelled in 1990. China continued the Super-7 project and renamed the design as the FC-1.

   The JF-17 Thunder has a conventional aerodynamic layout. Aircraft is fitted with Russian Klimov RD-93 turbofan engine with afterburner. It is a derivative of the RD-33, used on the MiG-29. In 2007 a contract was signed to supply 150 RD-93 engines for the JF-17, exported to Pakistan. China is also developing an indigenous turbofan engine, which is a copy of the RD-93, but has some modifications. It is designated as the WS-13 (Tianshan-21).

   The Thunder multi-role fighters delivered to Pakistan are fitted with Italian Grifo S-7 multi-track, multi-mode pulse Doppler radar. It has look-down, shoot-down capability. Other radars can be fitted. Avionics systems will be gradually upgraded in later batches.

   This aircraft is intended for air defense and ground attack missions. It is armed with a single 23-mm GSh-23 or 30-mm GSh-30 twin-barrel cannon. Maximum weapon payload is about 3.7 t. There are five hardpoints and two wingtips for missiles and fuel tanks. The JF-17 has beyond visual range attack capability. It's primary weapon are Chinese PL-12/SD-10 medium-range air-to-air missiles with active radar-homing. Aircraft also carries short-range Chinese PL-7, PL-8, PL-9 or US AIM-9P, mounted on wingtip rails. The JF-17 multi-role fighter can also carry general purpose of laser-guided bombs. Aircraft has no in-flight refueling capability.

   A twin-seater variant of this fighter is proposed.
