Variants
J-11AChinese/Russian assembled Su-27SK from Russian-made kits. 104 were built. They were later upgraded with MAWS. Unconfirmed upgrades include improved cockpit displays, and fire control systems for R-77 or PL-10 missiles. It is also called J-11.[1]
J-11BIndigenously-produced version using Chinese technology, and the first J-11 variant to use the WS-10A turbofan. The airframe is slightly lighter due to greater use of composites. It has new avionics, a glass cockpit, MAWS, and onboard oxygen generator system.[1]
J-11BSA twin-seat version of the J-11B. In 2012, the number of J-11B and J-11BS in service was over 120.[1]
J-11BHNaval version of the J-11B. It was first sighted in May 2010.[1]
J-11BSHNaval version of the J-11BS.[1]
J-15Carrier-based version based on the J-11B, incorporating structural elements from the Sukhoi Su-33 prototype purchased from Ukraine in 2001. It uses avionics from the J-11B.[1]
J-16Twin-seat strike fighter based on Russian Sukhoi Su-30MKK sold to China in 2000.[33] A further development of the J-11BS.[1]
J-11Dariant with fixed electronically scanned array radar, IRST, and capability to fire heavier imaging/infrared (IIR) air-to-air missiles. The airframe makes greater use of composite materials, especially in the engine intakes for lower radar observability.[1]
