The "D1101" prototype of J-11D Sino-Flanker was first spotted on April 29, 2015, powered by two WS-10A engines at Shenyang Aircraft Corporation (SAC) airfield.
The J-11D Flanker fighter jet with improved fly-by-wire (FBW) system and increased the usage of composites in the fuselage to cut overall weight of aircraft will result in increased maneuverability and control. The Infrared Search and Tracking (IRST) system has been moved to starboard side of the windshield, and retractable inflight refueling (IFR) probe was installed on the port side.
The J-11D will be able to carry new generation Chinese missiles like fifth generation PL-10 within visual range (WVR) high agility infrared homing air-to-air missile, Pl-12 / PL-15 Beyond Visual Range (BVR) missile and YJ-12 long range supersonic anti-ship cruise missile
The AESA radar for aircraft is developed by the 14th Institute and was tested on-board a modified J-11B fighter jet in 2014.
Shenyang Aircraft Corporation (SAC) has produced licensed version of Russian Sukhoi Su-27 Flanker fighter jet under designation of J-11 and later on started producing improved version under designation J-11B to make use of local engines, composite materials, radar, avionics, and weapons.
China has also developed J-15 Flying Shark carrier borne fighter jet for operations from CV-16 Liaoning Aircraft Carrier of PLA Navy.
