Shenyang J-11 ( Chinese trade. 殲 撃 十一 型 , comp. 歼 撃 十一 型 , pinyin : J iān jī shí yī xíng , pall .: Jian ji shi and sing or 歼 -11, Jiān-11, J- 11 , literally Fighter model 11 ) is a Chinese multi-role fighter, which is a licensed [1] version of the Soviet Su-27 fighter manufactured by the Shenyang Aircraft Corporation (SAC).

The basic version of the J-11, assembled from Russian components, is identical to the Su-27SK .
The J-11B variant uses the Su-27SK glider, but is equipped with Chinese avionics and weapon systems. In the future, it is planned to equip the J-11 with a Chinese turbojet engine FWS-10A "Taihang".
The Chinese media published an article stating that the J-11B, assembled from components made in China, surpasses the latest Russian Su-35S in terms of its technical and technical characteristics [2] . However, analysis and comparison of the characteristics of aircraft as a whole and their individual systems show that the J-11B slightly surpassed the original Su-27 and is approximately at the level of the Su-27M , that is, aircraft developments of the late 80s - early 90s [3] .

Production History
In 1992, China became the first country outside the former Soviet Union to adopt Su-27 fighters . In 1996, Sukhoi Company and SAC entered into a contract for the joint production of 200 Su-27SK under the designation J-11 in the amount of $ 2.5 billion. Under the terms of the contract, the J-11 was assembled at the SAC plant from Russian components. Perhaps a gradual increase in the number of Chinese components was agreed so that SAC could gradually master the independent production.
The first J-11 was assembled in December 1998, but serial production did not start until 2000 for technical reasons. Until 2003, 95 sets of aircraft were delivered to China, and the Chinese side refused the remaining 105, due to the fact that the basic version of the J-11 ( Su-27SK ) ceased to satisfy the requirements of the Chinese Air Force . [four]
Among the reasons for the rejection of further production were: the lack of agreement on the transfer of technology to the Chinese side in the contract, and, as a result, dependence on the supply of components from Russia; the incompatibility of the weapons control system with Chinese guided missiles and the need to purchase Russian R-27 and R-73 missiles in this regard; the primary purpose of the Su-27SK is to gain superiority in the air and the inability to use guided air-to-ground weapons.
The Sukhoi Company offered China a modernized version of the Su-27SKM with the possibility of hitting ground targets, but the Chinese Air Force abandoned it in favor of the J-11B.

Modifications
J-11B
In mid-2002, the SAC announced its intention to create an upgraded multi-purpose version of the J-11, capable of carrying guided air-to-air and air-to-ground missiles and containing more Chinese components. The aircraft received the designation J-11B. At least three J-11Bs have been built for testing since 2006.
The aircraft uses a J-11 glider ( Su-27SK ), but differs in the following features:
- Chinese multi-purpose weapon control radar capable of tracking 6-8 targets and directing missiles at 4 of them simultaneously;
- Chinese digital flight control system;
- Chinese copy of the Russian optoelectronic sighting system OEPS-27;
- inertial navigation system;
- indicator on a windshield of a cabin and four liquid crystal multifunction displays
The aircraft can carry Chinese short-range PL-8 and medium-range PL-12 guided air-to-air missiles, as well as YJ-91 ( X-31P ) and KD-88 guided missiles, as expected LT-2 and LS-6 aircraft bombs.
During the 6th aviation exhibition in Zhuhai from October 31 to November 5, 2006, China for the first time presented official data on its own development of the FWS-10A "Taihan" turbojet engine. The engine was successfully tested on a Su-27SK aircraft and, possibly, on a J-11. The engine is similar in design and characteristics to the Russian AL-31F engine . It is not known for sure whether it is mounted on a J-11B.
In 2007, there were reports of the development of a two-seat modification of the J-11BS fighter. In April 2009, his photograph was published, but the tactical and technical characteristics of the aircraft are not known. [6]
J-11D
In April 2015, modifications to the J-11D were tested. [7] The model received a new avionics from a more modern fighter J-16 (shock version of the double J-11BS). The aircraft is equipped with a radar with an active phased array, a new control system, as well as a new air refueling system. Composite materials are widely used in the design of the airframe. The machine will be armed with air-to-air missiles of the PL-10 and PL-15 type.
