The Shenyang Jian-11 (J-11) is a Chinese licensed copy of the Russian Sukhoi Su-27SK single-seat fighter aircraft. Under the 1996 agreement between Shenyang Aircraft Industry Company (SAC) and Sukhoi, China would build 200 J-11/Su-27SK fighters, initially using Russian supplied kits and later with greater indigenous contents. China is seeking to upgrade the J-11 with better avionics and weapon suites, and is currently developing new turbofan engine and fire-control radar for the aircraft. By 2004, about 90~100 J-11s had been built.

PROGRAMME

As agreed in principle in 1995, Russia agreed to allow China’s Shenyang Aircraft Industry Company (SAC) in Shenyang, Liaoning Province to co-produce as many as 200 Su-27SK single-seat fighters under license worth US$2.5 billion. The production initially consisted of assembly from KnAAPO supplied kits, but later leading to full production in China. Three years after the contract was signed, the first Chinese-assembled Su-27SK, designated J-11 by the PLAAF, rolled out at SAC. The production of the J-11 was reportedly delayed due to serious quality problems at the early stage, but the production had reached an impressive rate by late 2002. Russian sources confirmed that about 48 aircraft had been assembled by 2002, and another 48 between 2002 and 2003.

In late 2000 a high SAC official noted that not all 200 Su-27s might be built and there has been speculations that production would shift to a more modern design later. In mid-2002 SAC revealed its intention to build upgraded multirole version of the J-11 by revealing a mock-up armed with Kh-31P anti-radiation missiles (ARMs) and R-77 AAMs. The mock-up had the number “2001”, perhaps implying that was the year Sukhoi and Shenyang agreed to the upgrade. There appear to be two paths for these upgrades. The first follows the China-funded upgrade programme that Sukhoi is now marketing for other customers. This would give J-11s made before and after 2002 a progressively better radar and attack avionics suite to support advanced anti-air, ground attack and naval attack weapons.

J-11B

It also appears that the PLAAF may have more ambitious plans for the J-11. In mid-2002 Russian sources indicated Shenyang was also pursuing another multirole version of the J-11 (possibly designated J-11B) with much higher Chinese-made content. In particular SAC wishes to replace the Tikomirov NIIP N001 radar with a Chinese equivalent model Shedian-10, and the Lyulka-Saturn AL-31F engines with a local version Woshan-10A (WS-10A). The new J-11 version is also expected to be armed with Chinese indigenous weapons, including the PL-12 (SD-10) active radar-homing medium-range air-to-air missile and very likely, a new SRAAM in development, plus a range of ground attack munitions. It may take another ten years for SAC to fully indigenise the J-11. Once the design matures, SAC is likely going to market the fighter for export customers.

J-11C

Should the development of the J-11B prove a success, it would be a good candidate (J-11C?) for the PLA Navy’s first carrier-borne fighter. In contrast to the Chengdu J-10, which is also identified as a candidate fighter for a future PLA Navy carrier, the J-11/Su-27’s capability to take off and land on aircraft carrier has been proven by the Sukhoi Su-33, the Russian navy version of the Su-27. A J-11 with higher thrust WS-10A engines might be able to handle the Russian-style ski-jump taking-off. And as it built the Russian Navy’s Su-33s, KnAAPO would be a ready source for potential carrier-related modifications for the J-11.

WEAPONS

As well as Russian-made air-to-air and air-to-surface weapons, the future upgraded J-11 may also be able to launch Chinese indigenous weapons such as PL-12 (SD-10) active radar MRAAM, PL-8 SRAAM, YJ-91 anti-radiation/anti-ship missile, and various guided bombs.

POWERPLANT

China has been developing the indigenous WS-10A turbofan engine since the late 1990s, but is said to have encountered numerous technical difficulties. A WS-10A was seen fitted on a J-11 in 2002 for aerial tests. The WS-10A is said to have less thrust than the Russian AL-31F. This would result in the J-11 being less manoeuvrable than the original Su-27SK.

A ja mislio ti ces da stavis slike mnogo superiornijeg aviona za podrsku na zemlji - J-11 Orao 

Ma klasican SU-27 ......ali made in CHINA

......da baš tako samo me zanima koliko su rusi dobili $ za ovo......

11.000.000.000 za licencu,stim da nemaju radar(vec Kinezi ugradjuju svoje), i jos po neki nedostatak.

.........vau.....hvala ti na ovom podatku......

A jebiga Rusi su potrosili 5 puta vise u izgradnju flankera .......  ,a ovo i nije neka cifra.Znam da su Izraelci platili 6 milijardi za licencu izrade AIM 9 Sidewindera ....pa ti uporedi.
