não tem muito a ver com o JXX, mas pode ser um futuro oponente:

SEOUL — South Korea is likely to drop a plan to build its own version of a multi-role stealth fighter in partnership with Western aircraft makers, as the program has been assessed as nonviable both economically and technically, a military source here said.
The Korea Development Institute (KDI), a private economic policy think tank, concluded last month that the fighter development program, codenamed KF-X, would not be affordable based on a months-long study on the economic feasibility of the program, the source said.
The KF-X development would cost at least $10 billion but bring about only $3 billion in economic benefits, making the economics of the aircraft unsustainable, said the source, citing a KDI report commissioned by the Defense Acquisition Program Administration (DAPA), the country’s arms procurement agency.
The study result was reported to the presidential office, Cheong Wa Dae, he said.
The DAPA asked the KDI to update the report to make it public by March, he added.
DAPA officials, however, said the fate of the KF-X project has not been decided yet, citing arguments by some defense officials and analysts that the KF-X should go on despite its low economic feasibility, to further develop indigenous aircraft technology through joint research and development with foreign partners.
“The KDI report is just a tiny part of decision-making on the KF-X program,” Cmdr. Park Sung-soo of DAPA’s public affairs office said. “A final conclusion on the fate of the KF-X will be made after DAPA reviews all aspects of the program.”
The KF-X aims to produce a fifth-generation warplane suited to network-centric warfare after 2020 to replace outdated F-4Es and F-5Es and to market it globally.
Last November, the state-run Agency for Defense Development unveiled a plan to develop the KF-X fighter in cooperation with Western countries.
The agency said it wanted foreign firms to foot 30 percent of development costs and was considering forming separate consortiums between domestic and foreign companies on a case-by-case basis
Several foreign defense firms, such as Lockheed Martin, Boeing, General Electric, Saab and Safran, expressed their interest in the KF-X program, focusing on possible technology transfer and the potential market for the aircraft, ADD officials said.
The ADD aimed to build the KF-X stealthier than either Dassault’s Rafale or Eurofighter’s Typhoon but not as stealthy as the F-35 of Lockheed Martin, they said.
The fighter would be designed as a single-seat, twin-engine aircraft with a total thrust of more than 40,000 pounds, they said, adding the agency had two KF-X concepts, a wing-tail K-100 aircraft configuration and a canard-wing K-200.
Indigenous high-tech weapon systems such as precision-guided bombs, air-to-air and air-to-surface missiles would equip the fighter, while core technology, including aircraft system integration, avionics, fly-by-wire systems and stealth capabilities, would be obtained from partner companies via offset trading or domestic research and development, they said.
However, analysts have questioned the program’s affordability, as well as its overlap with the third phase of the existing F-X fighter acquisition program that is eying the F-35.
Seoul intends to buy 120 advanced combat aircraft under its F-X fighter modernization program.
In 2002, Boeing's F-15K Eagle was selected for the 40-plane, $4.2 billion first phase of the F-X fighter modernization program. The firm is in final price negotiations with the DAPA over the 20-plane, $2.4 billion second phase of F-X.
Seoul plans to open bidding in 2011 and acquire 60 fifth-generation stealth jets, aiming to deploy the planes between 2014 and 2019, according to Air Force officials.
The F-35 is regarded as the viable candidate for the third phase of the F-X program because the only other stealth fighter in the world, the F-22 Raptor, also built by Lockheed, may be out of Seoul's reach financially and legally. U.S. law forbids the export of the F-22, while the F-35 was developed specifically for export.
But if South Korea purchases F-35s for the F-X program, the value of the midclass KF-X fighter acquisition would likely be degraded because South Korea’s Air Force regards the F-35 as a midclass aircraft in terms of mission requirements.
“To be honest, it is very difficult to predict the fate of the KF-X program, as there are lots of question marks as to the level of technology, gestation period, development costs and so on,” said Lee Ju-hyung of the state-funded Korea Institute for Defense Analyses' Center for Weapon System Studies, who participated in the KDI’s feasibility study. “I just want to remind you that the foremost purpose of the program is acquiring state-of-the-art aircraft technology through joint research and cooperation with foreign countries.”

Le chasseur J-11, la copie "made in China" du Su-27 qui inquiète Moscou
publié le lundi 25 février 2008  

   
La Chine a réalisé une copie du chasseur Su-27, le fer de lance des exportations d’armement russe, et bien qu’il soit encore trop tôt pour envisager sa production en série, le géant asiatique constitue un concurrent potentiel peu rassurant aux yeux de Moscou, écrit jeudi le quotidien russe Vedomosti.
Moscou a livré 76 chasseurs Su-27SK à Pékin depuis 1992 et lui a vendu une licence d’acquisition de 200 appareils en 1995.

"La construction à partir de composants russes d’un appareil baptisé J-11 a démarré dès 1996 ", indique le quotidien.

Selon Vedomosti, la Russie a livré 95 kits destinés aux J-11 jusqu’en 2003, la Chine ayant par la suite refusé de signer un nouveau contrat portant sur 105 kits supplémentaires. La part des éléments chinois dans le J-11 a progressivement augmenté, mais les moteurs AL-31F et l’électronique étaient encore importés de Russie.

L’expert du centre américain pour les problèmes de défense et de sécurité internationale Richard Fisher avait prévenu dès 2003 qu’un J-11 totalement chinois était en cours de construction, et que celle-ci devrait durer 10 ans.
Mais les Chinois ont été plus rapides que prévu, constate Vedomosti.

"Le boum de la production de propulseurs a permis de faire progresser la part des pièces chinoises de 70-75% à près de 90%", indique Andreï Plotnikov, représentant de Rosoboronexport, l’entreprise publique russe chargée de l’exportation d’armements, en Chine.

La mise au point par le constructeur chinois AVIC I du propulseur WS-10, aux caractéristiques analogues à celles de l’AL-31F, s’est achevée en 2006.

Rosoboronexport s’est abstenu de tout commentaire, tout comme l’ambassade de Chine en Russie et la Commission chinoise des sciences, des techniques et de l’industrie pour la défense nationale, annonce Vedomosti.

Un haut représentant du holding russe a cependant fait savoir que plusieurs J-11 "100% chinois" auraient été montés. Il n’est pas question selon lui d’un assemblage en série pour l’instant.

Le Su-27 et son successeur le Su-30 sont le fer de lance des exportations de Rosoboronexport, la livraison de ces avions ayant rapporté à elle seule 50% du chiffre d’affaires du holding en 2007.

Si les experts chinois se lancent dans la fabrication en série du Su-27, le pays pourrait facilement devancer la Russie, et il serait en outre très difficile de prouver la contrefaçon d’équipements techniques d’une telle complexité, estime Kontantin Makienko, expert du Centre d’analyse des stratégies et des technologies.
Vedomosti conclut en rappelant que la Chine produit depuis longtemps légalement, mais aussi parfois sans licence, des appareils identiques aux avions soviétiques. Les J-6 et J-7 sont les analogues des MiG-13 et MiG-21, le bombardier N-6 reproduit le Tu-16, et les avions de transport Y-5, Y-7 et Y-8, sont les copies conformes des An-2, An-24 et An-12.

Mais uma vez temos os exemplo, do que os chineses querem, roubar a tecnologia militar, o mesmo vai acontecer quando os europeus começarem a vender, para lá e assim poupasse os anos de investigação e desenvolvimento, assim não custa ter forças armadas evoluídas, copia-se e depois acabasse com os mercados, pois vendem mais barato.

Copiar não é simples nem fácil e nem sequer consegue reproduzir sempre bons resultados. A China é o exemplo desta situação, tenta copiar tudo mas muitas vezes com resultados pobres.

Mesmo assim não confio na tecnologia chinesa, penso que a semelhanca de tudo o que fazem não presta.

Se calhar esta minha opinião se deve a ter trabalhado 3 anos e meio para uma empresa chinesa, mas não os tenho em grande estima.

Chinese Military Won't Accept 'Made In China' Fighters

BEIJING (Kyodo) -- China's Air Force has refused to accept 16 J-11B fighters manufactured by a domestic aircraft maker due to technical problems, the Kanwa Defense Review magazine said in its June issue, quoting a Western intelligence source in Beijing.
China is believed to have developed the new fighter based on technology from the Russian fighter Sukhoi Su-27, sparking speculation that the maker, Shenyang Aircraft Corp., may have failed to employ Russian technology accurately.
Shenyang Aircraft, based in Liaoning Province, manufactured 16 J-11B fighters in 2009.
"When the Air Force was checking them up for delivery, J-11B had abnormal vibration after taking off," the magazine quoted the source as saying. "As a result, the Air Force refused to accept the aircraft."
A Chinese military source said the J-11B was not chosen for exhibition at the National Day military parade in October last year due to doubts over technical feature of the fighter, according to the magazine.

Não era o Chinês que queria apagar a imagem do "Made in China"... nada como negar a própria produção!
