Chinese substantially modified their locally produced flankers, to be called J11, the latest J11 B model only shares the same airframe to the original Su27, but every thing inside, from powerplant, Radar, weapon system, Avionics all are indigenously made. Look at the below image, the Chinese J11B features a Holographic HUD, you can find same type of system in f22 as well, and you also can compare the J11BÂ’s c-ockpit to that of original Su27SK in 1990s.
Below is J11B image released from Chinese media, quite a mighty Flanker
More detailed reads on Chinese indigenous Flanker, the J11B, from AWST:
Chinese J-11B Presages Quiet Military Revolution ...The nationally developed systems now in various stages of the J-11B test program potentially provide performance improvements over the various Su-27 models now in PLAAF service.
Air Show China, held here Oct. 31-Nov. 5, included the first official detail about the Shenyang Tai Hang engine. This turbofan powerplant is being developed for the Flanker, and is also sometimes referred to as the WS-10A. A handful of J-11B airframes are now likely being used for development testing, including at least one J-11B engine-integration aircraft.
Beijing and Moscow first agreed on the Flanker sale in 1991, with a license production contract signed in 1996. The Flanker has given China its most capable fighter aircraft while also providing a vehicle for its industry to gain knowledge of fourth-generation fighter manufacturing. The first kit-built J-11A was completed in 1998. The J-11A still uses Russian engines, radar and weaponry.
Design and development of the Tai Hang has been underway for nearly two decades, says one senior Chinese aero-engine executive. He admits the program has proved challenging: "We hit difficulties in developing the engine."
Chinese industry executives attending the show remain reticent to discuss the J-11B program. The executive would say only that the Tai Hang has "similar applications to the Al-31 [the present Su-27 engine]. It's of a similar thrust and is of the same technology generation." The J-11B program also includes the integration of Chinese-developed planar array pulse-Doppler radar replacing the Russian N-001 cassegrain radar, at least two versions of which are fielded by the PLAAF. An image of a J-11B, still in its primer (see top photo on p. 27), appears to show the aircraft fitted with a different radome to the basic Su-27. Given the available space for a flat-plate antenna, this would offer a performance improvement over the N-0001.
Also associated with the J-11B is the Luoyang PL-12 active radar-guided medium-range air-to-air missile. While the Chinese air force already has the Russian R-77 (AA-12 Adder) in service with the Su-27, the PL-12 offers a big performance increase over the present export standard of the Vympel R-77. Officials from the company were unable to discuss the PL-12 project.
The initial development test-firing program for the overall PL-12 program now appears complete, with the missile at least close to service entry. It was integrated first on the J-8II for the development program. Trials of the PL-12 on the Chengdu J-10 also have been carried out.
The PL-12 does benefit from Russian technology, with the seeker and inertial guidance system provided by Moscow. A variant of the Agat 9B-1103M radar seeker is the most likely candidate for the missile. This seeker was intended initially for an improved version of the R-77, but appears to have been sold to China first.
The PLAAF currently has the capability for two-target engagement using the Su-27, R-77 combination. Successful integration of the PL-12 on the J-11B would likely provide a genuine multitarget capability and give the PLAAF a more capable air superiority aircraft...
