   Chinese air force has been looking for a way to produce a counterpart to the fourth generation fighter jets, used by NATO countries. The first idea about developing a Soviet-like fighter emerged in late 70s when Shenyang factory combined a light fighter design of the Soviet MiG-19 with a British Rolls-Royce Spey 512 engine. This project was known as the J-11, but eventually failed. However this idea was resurrected two decades later.

   In the 1990s China signed an agreement with Russia, that allowed to build 200 Su-27SK aircraft from Russian-supplied kits. Production of the J-11 began in 1998. It made its maiden flight during the same year. However co-production of the basic J-11 was halted after around 100 aircraft were built. Later Chinese produces their indigenous version of this aircraft.

   The J-11 is a twin-engine, single-seat air superiority fighter, based on the Sukhoi Su-27s design. It has a Western reporting name Flanker B+. At the time of its introduction it was a fairly respectable fighter jet with Russian engines and weaponry. It was a noteworthy adversary to US-made aircraft, such as Lockheed Martin F-16 Fighting Falcon or Boeing F/A-18 Hornet.

   So far, there are 253 aircraft of various versions built and the production keeps on going. Produced in the Shenyang Aircraft Corporation in Northern China, all of the Shenyang J-11 aircraft, including the J-11A, J-11B, J-11BS, J-11D, J-15, and J-16 versions are used solely by Chinese People's Liberation Army Air Force. It has never been exported.

   The first 100 Shenyang J-11 aircraft were fitted with Russian-made Lyulka Saturn AL-31 engines. However, the later versions, namely J-11B and J-16 use Chinese-built Woshan WS-10A "Taihang" turbofans.

   Performance of the basic version of this aircraft, the Shenyang J-11, is very similar to Sukhoi Su-27, not only because of an almost identical design, but also because of the equipment. This version employs Russian equipment like NIIP Tikhomirov N001V radar and armament including Gryazev-Shipunov GSh-30-1 autocannon and Vympel NPO missiles.




   J-11A is basically the same aircraft as J-11, the only difference being in improved equipment. This version is equipped with a different electronic flight instrument system;

   J-11B is an indigenous Chinese version, fitted with locally-built radar, avionics and weapons. Some sources report that up to 90% of components are indigenous. It also has some upgrades to the airframe. Existence of this aircraft was confirmed in 2007;

   J-11BS, a two-seat version of the J-11B. Essentially it is a combat-capable trainer aircraft, similar to the Russian Su-27UB. The first prototype was revealed in 2007;

   J-11D, an improved version of the J-11B, fitted with AESA radar and upgraded WS-10 engine. Other improvements include new cockpit, more radar absorbent materials, two additional hardpoints, in-flight refueling probe, new electronic warfare systems;

   J-15 is a carrierborne version, equipped with Chinese-equipment and weaponry. The aircraft is nicknamed the Flying Shark for a good reason it is faster than its predecessor, with the top speed of 2 940 km/h and higher service ceiling;

   J-16 is the latest model coming out of the Shenyang Aircraft Corporation. It is an advanced version of J-11, based on the Su-30MKK. This is a two-seat multi-role fighter. Its production began in 2012. The J-16 made its first flight in 201r. Currently Chinese air force has 24 of these aircrafts, with the order of a whole regiment.
