Sino-Soviet Split to the Reform Era (1960-1977)

At the time of the Sino-Soviet split, China possessed a military aviation industry with fully operational production facilities, almost a decade of experi­ence manufacturing advanced fighter and bomber systems, and a reasonably well-equipped air force modeled along Soviet lines. However the withdrawal of Soviet advisors and technical assistance in July 1960 and the intensification of the Sino-Soviet split in the early 1960s had major consequences for the PLAAF and the Chinese aviation industry.55 As relations between China and the Soviet Union deteriorated, the PLAAF lost the option of buying new and updated Soviet fighters and the Chinese aviation industry lost access to technical support from Soviet advisors to help improve aircraft production and master key tech­nologies. The Chinese defense industry would spend much of this period strug­gling to absorb and extend the technology it had acquired from its coproduction deals with the Soviet Union or reverse engineered from its Soviet aircraft.

In the wake of the Sino-Soviet split, China lacked a relationship with another advanced country to acquire cutting-edge military hardware. Western export controls focused on preventing exports of militarily relevant technolo­gies to the Eastern bloc foreclosed the “buy” option. Even after China’s rap­prochement with the United States in 1971, it took a number of years before the United States and European countries were prepared to ease export con­trols on military technology, pursue arms sales, or engage in defense indus­trial cooperation. The one noteworthy exception was a 1975 agreement (nego­tiations began in 1972) whereby Britain supplied China with 50 Spey fan-jet engines, the powerplant used in British versions of the multirole F-4 Phantom (the RN F-4K and RAF F-4M), as well as the Vought A-7 Corsair light attack aircraft.56 China was given full production rights and began trial manufactur­ing the Spey RB-168-25R as the WS9 at its plant in Xi’an. Under the terms of the agreement, Rolls Royce provided both manufacturing facilities and tech­nical expertise involved with testing the Chinese-produced Speys. To date, the Xian JH-7 fighter bomber is the only PLAAF aircraft powered by a variant of the original Rolls Royce Spey or the Chinese-manufactured WS9.57 While the Spey arrangement was not a direct transfer of weaponry per se, it involved a single-use technology applicable only to combat aircraft and should thus be considered a transfer of military equipment.

Political restrictions on importing military hardware from the West were further aggravated by the fact that very few Chinese citizens were permitted to go abroad (even Chinese diplomatic missions were withdrawn from most countries during the Cultural Revolution), making it difficult to access the sorts of restricted technologies worth stealing. Obtaining access to informa­tion about improvements in Soviet weapons systems from other members of the Eastern bloc and developing country customers would have been a logical approach, but little information is available about the extent to which China pursued this direction and what success it might have had.

These challenges were compounded by the massive social upheavals and the cumulative impact of the Great Leap Forward and the Cultural Revolu­tion, which stymied development of the Chinese economy for a decade, lim­iting the ability of the Chinese civilian economy to produce technologies that the military could incorporate into weapons systems. Industrial output not related to the defense sector was severely affected by the Cultural Revolution as capable individuals with managerial and planning roles in key enterprises were branded bourgeoisie reactionaries and removed from their positions. The damage done in this respect had long-term consequences for many sectors of the Chinese economy. Despite efforts to protect scientists and engineers work­ing on high-priority defense projects, chaos in the wider economy inevitably had a negative impact on China’s aviation industry.58

Although the Central Military Commission ordered the aviation minis­try to commence R&D programs on some 27 new types of aircraft in 1971,59 in reality China’s aviation industry had its hands full mastering production and extending the designs of Soviet fighters and bombers designed in the late 1950s. For example, the design of the J-7 (China’s MiG-21 variant) was not finalized until more than a decade after its initial flight test in 1966 and it was not approved for serial production until 1979.60 China’s aviation industry even­tually proved capable of absorbing 1950s Soviet aviation technology and by the end of this period had developed some limited design innovations (for exam­ple on the J-7/F-7) via reverse engineering efforts that went a step beyond copying. However, by the time the Chinese industry reached this point, both Western and Soviet air forces had moved on to more advanced fourth-gener­ation aircraft that made China’s most advanced aircraft effectively obsolete as soon as they rolled off the production line.
