Chengdu J-10 (Jian-10 Fighter aircraft 10) / F-10

There has been much speculation on the development of China's J-10 fighter. Many suggested the aircraft's design was based on the Lavi- the unsuccessful attempt by Israel to develop an indigenous F-16 fighter. Only in December 2006 did China officially acknowledged the fielding of the J-10, when the PLA Air Force (PLAAF) released videos and photos of the aircraft via China Central Television (CCTV) and Xinhua News Agency. By then, it was apparent that the J-10 has the potential of becoming one of the most significant fighters in the next few decades.

Initial development of the J-10 began in October 1988. Originally the aircraft was to be an air superiority fighter. The 1980s saw a number of similar aircraft designs featuring a main delta-wing and canards. The delta-wing, a triangular wing platform, offers two important aerodynamic qualities to a combat aircraft. First, the swept leading edge of a delta-wing stays ahead of the shock wave generated by the nose of the aircraft during supersonic flight, making delta-wing a very efficient aerodynamic wing shape for supersonic flight. And secondly, the leading edge of delta-wing also generates a massive vortex that attaches itself to the upper surface of the wing during high angle-of-attack (AOA) maneuvers resulting in very high stall points. Additionaly, the delta-wing offers increased survivability by having increased structural and airflow stability.

By 1993 the Chinese possessed an all-metal mockup of the J-10. Wind tunnel testing revealed potential problems with low-speed performance and less than expected maximum AOA at subsonic speeds. At the time, there was an ongoing trend in fighter aircraft development that moved the development of single-purpose fighters such as high-speed interceptor or low-altitude dogfighters to polifunctional aircraft that combined subsonic and supersonic air-to-air performance with air-to-ground capabilities. Increasing demands for air-to-ground operations called for an in-depth redesign of the J-10 to accommodate terrain-following radar, more and sturdier hardpoints, and entirely new targeting, flight control and navigation systems.

The first test flight of the J-10 came in 1996 with the help of a Russian made AI-31FN turbofan engine. It would take two years, however, before the J-10 had a successful test flight. By 1999 China had six prototypes: four of them used for flight testing and two for static tests. By late 2000 there were nine J-10 prototypes accumulating over 140 flight hours. The first flight of the pre-production model took place on June 28, 2002. In early 2003 ten J-10s were deployed to Nanjing Military Region for training and operational evaluation.

Development would not stop, however, as China also began to construct two-seat versions of the J-10 for training and air-to-ground roles. This two-seat J-10B fighter-trainer aircraft successfully flew in 2003. Preliminary designs for two new versions of the J-10 featuring single and twin engines and LO geometry were also completed.

Low-rate initial production of the J-10 was authorised in 2002, with the initial run of fifty aircraft to be fitted with Russian AL-31F engines. The J-10 is expected to achieve initial operating capability in the 2005 to 2006 timeframe, initially entering service with the 44th Aviation Division based in Sichuan Province. The PLAAF initially was estimated to have a total requirement of 300 aircraft, but this may be reduced to less than 100 as a result of the introduction of the more capable Su-30MK multirole fighter.

As the Chinese continue to develop and improve the J-10 it becomes clear they are interested in expanding its air-to-ground capability, thus moving from the original concept of a tactical air defense fighter to a multirole fighter-bomber. The change in Chinese reporting of the J-10, from the "Jian-10" ("Fighter-10") to the "Qian Shi-10" ("Attack 10") is proof of this intended move.

Russian involvement in the J-10 program was not limited to the AI-31FN turbojet engine, but also included offers for advanced multifunction radars, navigation and targeting systems, ECM suite, and missile warning and defense systems. For the J-10, the Chinese will most likely adopt the Phazotron RP-35 "Zhemchug," which is an X-band radar with digital fire-control sensors and an electronically scanning phased-array antenna. The radar features a liquid-cooled travelling wave tube transmitter; an exciter; a three channel microwave receiver and programmable signal and data processors. All critical radar controls for "Zemchug" are integrated into the aircraft's throttle grip and stick controller, and radar data is displayed via the head-up and head-down displays allowing for one-man operation.

The production of the J-10 has forced China to quickly adapt to current developmental trends; in addition to utilizing other technologies (Russia, Israel) for the benefit of its final product. The results are promising. Not only does the J-10 pose a risk to the Russian fighter export market, but it considerably boosts the Chinese air force's tactical offensive capabilities, especially vis-a-vis Taiwan.

The J-10B Super-10 is an advanced variant of the J-10A, first fielded in late 2003 with China?s Air Force. The new Super-10 will reportedly be powered by the Chinese-designed WS-10A turbofan engine, which will replace the J-10A?s Russian Saturn AL-31FN. The J-10B was first revealed to the public in early 2009. Images appearing on Chinese-language military websites indicate the J-10B had a new nose configuration with an infrared search and tracking system and a ?new Diverterless Supersonic Intake configured engine air intake, also seen on the Chengdu FC-1 Xiaolong (Fierce Dragon), which is co-produced in Pakistan as the JF-17 Thunder. At least one prototype J-10B has featured the indigenous Shenyang-Liming WS-10A turbofan engine, but it remained to be seen whether all production J-10Bs will feature the WS-10A or the Russian Saturn AL-31F turbofan.

On 06 November 2013 Zhang Jigao, deputy chief designer of the J-10 fighter, spoke about the improved model J-10 publicly for the first time in the AVIC flight test center. Zhang Jigao said that the overall performance of the J-10 will be comprehensively improved in areas such as aerodynamic layout, mission system, and the approach to maintenance. Zhang Jigao added that further improvements to the performance of the J10 would focus on the aircraft's aerodynamic layout and mission systems, and the approach to maintenance. "Aircraft development requires constant optimization and improvement," he said, "and our modifications will be comprehensive rather than being confined to a specific area."

U.S. military expert Richard Fisher recently pointed out that the J-10B is a so-called "fourth and a half" generation fighter equipped with modern airborne technology and an advanced radar system, which is about to be delivered to the PLA Air Force. Zhang Jigao disputed the term "fourth and a half" generation. In contrast, he suggested that the current international criteria to classify generations are more applicable. He pointed out that single combat is rare in modern warfare, and that the majority of cases now involve system combat and network operations, so that the combat capabilities of a fighter depend on many factors. "This does not mean that the optimization of an aircraft's radar, avionics, and missile detection ranges are bound to improvements in operational performance."

Pakistan signed a $1.4 billion deal with China in 2009 to buy 36 J-10B Vigorous Dragon multirole fighters. according to Defense News on 07 October 2013, the most probable buyer of J-10, Pakistan, might put off the purchase plan under the influence of economic factors and technology maturity. By 2013 tough International Monetary Fund conditions on Pakistan and concerns about untested technology delayed Islamabad's plan. At $50-60 million per aircraft, it might become attractive to countries like Venezuela, Argentina, Peru, Malaysia and Indonesia.

As global attention has been drawn to when China's in-service top-grade home-made J-10 fighter aircraft enters the international market, Ma Zhiping, vice president of the China National Aero-Technology Import and Export Corporation (CATIC), disclosed recently that many countries in Asia, Africa and Latin America had already enquired about price of J-10. According to Ma Zhiping, many clients have contacted to enquire the price of J-10 series fighters. These clients came from various countries in Asia, Africa and Latin America and include those traditional users of Chinese military aircraft as well as those countries which previously used Russia's series fighters and French fighters.

Ma Zhiping made a clear statement in an interview by reporters from Global Times on September 25 that: "We can say in a very responsible way that the J-10 fighter aircraft hasn't been exported to Pakistan. The export of a model of military aircraft has to be approved by the country first. However, J-10 hasn't acquired the related export license so far." Ma said on the sidelines of the ongoing 15th Aviation Expo/China 2013 in Beijing "Obtaining a national permit in advance of exporting it is top priority". Export would improve China's market competitiveness in the international arms trade as other countries, such the US and Russia, are eagerly promoting their third-generation jets - the F-15, F16, Su-27 and Su-30 - worldwide, while China's customers, in contrast, are still using the second-generation J-7 or J-8.
