Shenyang J-11

The Shenyang J-11 with NATO reporting name: Flanker B+ is a single-seat, twin-engine, jet fighter, whose airframe is based on the Soviet-designed Sukhoi Su-27 (NATO reporting name: Flanker) air superiority fighter. It is currently 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 McDonnell Douglas F-15 Eagle, Eurofighter Typhoon and Dassault Rafale.

In March 2011 a joint Sino-Pakistani exercise, Shaheen 1, was conducted at a Pakistan Air Force (PAF) base involving a contingent of Chinese aircraft and personnel from the PLAAF. Information on which aircraft were used by each side in the exercise was not released, but photos of Pakistani pilots inspecting what appeared to be Chinese Shenyang J-11B fighters were released on the internet. The exercise lasted for around 4 weeks and was the first time the PLAAF had deployed to and conducted "operational" aerial maneuvers in Pakistan with the PAF.

The J-11B, along with the J-10A and Su-30MKK, was deployed to enforce China's Air Defense Identification Zone.
