The Chengdu J-10, also known as Menglong ('Vigorous Dragon', NATO reporting name: Firebird) is a Chinese medium-weight, single-engine, multirole combat aircraft using a delta wing and canard design, with a maximum speed of Mach 1.8. It is produced by the Chengdu Aircraft Corporation (CAC) for the People's Liberation Army Air Force (PLAAF) of China, and exported to the Pakistan Air Force (PAF).

In 1981, PLAAF Commander Zhang Tingfa submitted a proposal to Deng Xiaoping for the development of a third-generation fighter for CNY 500 million; it was accepted later that year by the Central Military Commission (CMC). It was the first Chinese aircraft program to incorporate modern development and acquisition processes. In one departure from the past, the supplier was now responsible directly to the customer; this allowed the PLAAF to communicate its requirements and ensure they were met; previously suppliers were responsible to their managing agency, which could produce products that failed to meet end user requirements. Another difference was the selection of a design through competition, rather than allocating a project to an institute and using whatever design that institute created.

Design proposals were made by the three major aircraft design institutes. Shenyang's proposal was based on its cancelled J-13 with a F-16-like strake-wing. Hongdu's proposal was MiG-23/Su-24-like with variable-sweep wing. Chengdu Aircraft Design Institute's (CADI) proposal was a Saab 37 Viggen-like design based on its cancelled J-9. CADI's proposal was selected in February 1984. The following month, CADI and Chengdu Fighter Factory were formally directed to develop and manufacture the aircraft, respectively.

The engine was selected during the design proposal stage. Candidates were an improved Woshan WS-6, the WP-15, or a new engine. The new engine, ultimately the Shenyang WS-10, was chosen in 1983.

The State Council and the CMC approved the program in 1986, code-naming it "No. 10 Project". Interest waned in the following years which constrained funding and prolonged development. The Gulf War renewed interest and brought adequate resourcing. Unlike earlier programs, the J-10 avoided crippling requirement creep.

Technical development was slow and difficult. The J-10 represented a higher level of complexity than earlier generations of Chinese aircraft. About 60% of the aircraft required new technology and parts, instead of - according to Chengdu - the usual 30% for new aircraft; the high proportion reflected both requirements and limited domestic capability. Development and modernization of China's aviation industry occurred alongside the J-10; the program was an early Chinese user of digital design, modelling, and testing including computer-aided design (CAD) and computational fluid dynamics. The J-10 was the first Chinese aircraft to make major use of CAD for its structural design, allowing the detailed design to be completed in 1994. The hydraulics system was tested with physical models because of limited digital modelling capabilities.

Historical Account: "A Modern Day Whodunit" - In 1988, Israel's defense minister denied a report by The Sunday Times that Israel and China had agreed to develop a fighter derived from the IAI Lavi. In 2006, Russia's SibNIA engineers believed that the J-10 was "more or less a version" of the Lavi, incorporating "a melting pot of foreign technology and acquired design methods... but there are a number of other pieces of other aircraft or technologies that are part of the configuration that they have acquired from different sources." In 2008, Janes claimed that the J-10 benefited from technical information from the Israeli project, citing senior Russian engineers who said they had heard this from Chinese colleagues.

The Chinese assert J-10's features claimed to be from the Lavi are from the manufacturer's own previous aircraft design, for example attributing the J-10's Lavi-like double canard configuration to Chengdu's work on the cancelled J-9 of the 1960s and 1970s; this view is supported by Song Wencong, who worked on the J-9 and became the J-10's chief designer, and PLAAF Major General Zhang Weigang.
