Shenyang J-11

The Shenyang J-11 (Chinese: 歼击机-11/歼-11; pinyin: Jianjiji-11/Jian-11) with NATO reporting name: Flanker B+ is a single-seat, twin-engine jet fighter based on the Soviet-designed Sukhoi Su-27 (NATO reporting name: Flanker) air superiority fighter and manufactured by the Shenyang Aircraft Corporation. The People's Liberation Army Air Force (PLAAF) of the People's Republic of China (PRC) is the sole operator of the aircraft.

The base J-11/A is a fourth-generation jet fighter which, like its Sukhoi brethren, is intended as a direct competitor to Western fourth generation fighters such as the F-15 Eagle and F-16 Fighting Falcon.
