J-8 (Jian-8) /F-8 Fighter aircraft

The J-8 was the first PLAAF aircraft of domestic design, with design work beginning in 1964. The overall configuration is a rather straightforward enlargement of the MiG-21/J-7 layout to accommodate two engines. Although it resembled Mikoyan’s experimental Ye-152A, contrary to some early reports, it was not based on that aircraft.

Production began in December 1979, with about 100-150 units of the first configuration entering service. Design work on the improved J-8-2 began in 1980, with production beginning in the late 1980. As with the cancelled “Super 7” upgrade to the single-engine J-7, the J-8-2 completely reworks the front end of the aircraft, adding a much larger radar and ventral air inlets, along with various other less pronounced improvements. The best that can be said of the J-8 is that once upgraded it will be no more than an advanced obsolete aircraft, comparable in configuration and aerodyanmic performance to the Su-15 FLAGON.

The Jian-8IIM upgrader, co-developed by China and Russia, is the result of a thorough modernization of the F-8M fighter (“M” standing for export-only weaponry in China’s weapon designation system) and has actually become a new-generation fighter plane. The first flight of this version was conducted on 31 March 1996. It features upgraded electronics systems, the lack of which has disadvantaged China’s fighter planes for a long time.

The J-8 and J-8II aircraft are trouble-prone aircraft with a poor weapon suite and an inefficient engine. At best, the J-8-II can be compared with an early model (1960s) US F-4 Phantom. In fact, after twenty-six years the J-8-II is still in the development stage, has resulted in only about 100 fighters deployed, and meets none of the requirements of the PLAN.

The Jian-8IIM fighter will probably be equipped with Russia’s or China’s helmet sight and advanced PL-9 and P-73 missiles, with which it will outperform the F-16C in close-range air combat. Phazotron, a Russian firm, has signed contracts with China to provide 150-200 improved Zhuk radars mainly in support of China’s new F-8II fighter, but also to equip the new Chengdu J-10 fighter. These radars have six times the data and signal processing power of the basic variant and greater detection range than the current 80KM. They can track while scanning on 24 targets, display up to 8 of them, and simultaneously provide fire-control solutions for 2-4 of them.

The Jian-8IIM does not use large amounts of expensive composite material and titanium alloy, and it is not equipped with complicated maneuverable flaps, as found on the F-7MG. Though mature and reliable, the Jian-8IIM is rather cumbersome. With a fuel load exceeding that of the F-7, its operating range is shorter than that of the latter. However, if specified by a customer, the Jian-8IIM could incorporate composite material, titanium alloy, and maneuverable flaps to further enhance its maneuverability and expand its external storage capacity and radius of action.
