Chengdu (AVIC) J-7 / F-7

History

After World War II (1939-1945), China and the Soviet Union were cooperating political powers. Naturally, this led to China being the recipient of modern technologies developed by Soviet engineers.

Eventually, the introduction of Soviet aircraft, tanks and small arms enabled the Chinese to use the Mikoyan-Gurevich MiG-15 "Fagot" jet fighter in the Korean War. In 1955, the Soviet government granted China a license to produce the MiG-17 jet fighter, and hundreds of them were produced locally. Hands-on experience building advanced jets eventually enabled the booming Chinese aviation industry, centered on ordnance, airframes and engines. For decades, reverse-engineering military weapons has showcased a certain amount of Chinese talenta feature that continues to this day.

After all, the two-seater trainers, which are designed, developed and produced entirely in-house, are all done in-house. Licensed production of the MiG-19 then entered the 1960s, although this period was quickly hampered by the Sino-Soviet split of 1960-1989, and political and military partnerships deteriorated.

Despite the differences, relations apparently eased during this period, enough to open the door for the Soviet Union to introduce their new MiG-21 "Fishbed" interceptor to the Chinese. Licensed for production in 1962, the local Shenyang company was commissioned to replicate the MiG-21F-13 "Fishbed-C" and its RD-11F-300 series engines. The Soviets helped with staff, aviation agencies, and kits, which were shipped to local Chinese rallies. At China's initiative, the MiG-21F was designated "J-7", while its export counterpart became "F-7".

The corresponding engine copy is the localized "WP-7" product. The first engine tests took place in October 1965, and the prototype was completed in November of the same year. The first flight of the Chinese F-7 was on January 17, 1966.

This model proved to be a viable replica, and serial production was ordered, albeit slowly, from June 1967. The arrival of the "Cultural Revolution" (1966-1976) accelerated production, which was then distributed to the Chengdu factory.

The revolution undoubtedly hurt the J-7 at first, as the outage delayed the system's full operational status until the early 1980s. Since then, many problems have become apparent, as the Chinese product proved to be underperforming compared to the Soviet version.

The problem was not resolved until 1985.

The core of the F-7 can be considered a perfect replica of the excellent and widely used MiG-21 of the 1960s. The fuselage is mostly tubular, with a low-set delta main wing and a swept-back tail. The aircraft relies on a vertical tail. The cockpit is set up nicely with a light framed canopy.

There is no traditional nose cone, as the nose is open to allow the single-engine armature to breathe. The landing gear is fully retractable and consists of two single-wheel main legs and a single-wheel front leg.

Chinese production has enabled Chengdu to sell versions of their aircraft to budget buyers around the world, and many parties have accepted Chinese offers. This type has proven very popular in Africa, the Middle East and South Asia, where it finally provides a powerful interceptor with additional strike capability at cost.

Advances in the J-7 line contributed to the type's effectiveness, although it was almost always a decade or so behind its Western competitors.

The first production model, simply called the J-7 (export model F-7), was committed in 1966 by 12 people from the Shenyang company. These versions have only a single 30mm NR-30 cannon and two underwing hardpoints for mounting air-to-air munitions as usual. The J-7I is an improved J-7 now handled by Chendgu and introduced in the 1970s. A variable air intake was installed on the original fixed version, and the 2 x 30mm guns completed the standard armament installation.

This resulted in an upgraded J-7I ("modified") with an improved hydraulic system (a clear problem area for earlier installations). From there, the J-7 appeared in a plethora of viable hunters, interceptors, and attack mounts, which proved to be increasingly popular around the world.

Albania and Tanzania were among the first F-7 operators to receive export-oriented F-7A variants. Pakistan became a strong supporter and key Chinese customer for the F-7 product line, as well as elsewhere. Egypt uses the F-7, as do North Korea and Bangladesh. Iraq became a former operator after the 2003 U.S.-led invasion, with 80 of them permanently decommissioned. Work on an improved J-7II began in 1975 with a more efficient and powerful engine.

These aircraft have been used in Egypt and Iraq (as F-7Bs) since the 1980s.

The F-7M "Airguard" variant is an upgraded J-7II variant intended for export sales and equipped with western-facing avionics to appeal to a wider mass market. Added extra hardpoints, as well as UK and US interior systems.

More powerful engines work in tandem with a new swept delta wing design for improved performance and handling. The J-III followed, largely based on believing the MiG-21MF in Egypt and reverse-engineered by Chinese engineers for replication and eventual resale. These new mounts provide a new radome assembly for the all-weather attack radar, a capability many previous models lacked.

A local company in Guizhou manages the production of the JJ-7 and FT-7 and two-seat trainers of similar models.

There are other J-7/F-8 variants (see variant list below for full list). Many only made minor changes to design (HUD support, in-cockpit MFDs, HOTAS, etc.) and functionality, while others were overhauled or completely rewritten but never implemented. In any case, the F-7 is more or less past its prime, and by modern standards it's a declassified fighter anyway.

However, it proved to be relatively inexpensive to acquire and enabled many countries to provide it with reasonable range air service, especially when 1960s fighter jets were sufficient to subdue weaker neighbors.
