    Pakistan’s efforts to have a sea-based minimum credible nuclear deterrent vis-a-vis India took a significant step forward last month when the state-owned, Wuhan-based China State Shipbuilding Industrial Corp (CSIC) ferried the first Qing-class conventional attack submarine (SSK) to Shanghai to begin a year-long series of sea trials, which is likely to include the test-firing of three CJ-10K submarine-launched, 1,500km-range land attack cruise missiles (LACM) capable of being armed with unitary tactical nuclear warheads. Called the Qing-class SSK, it is a variant of the Type 041A Improved Yuan-class SSK, which is also due to begin its sea trials later this month.

    It is now believed that the contract inked between CSIC and Pakistan early last April (see FORCE April 2011, pages 16-17) calls for the CSIC’s Wuhan-based Wuchang Shipyard to supply six Qing-class SSKs, all of which will be equipped with a Stirling-cycle AIP system and will be able to carry up to three nuclear warhead-carrying CJ-10K LACMs each. The double-hulled Qing-class SSK, with a submerged displacement close to 3,600 tonnes, bears a close resemblance to the Russian Type 636M SSK, and features hull-retractable foreplanes and hydrodynamically streamlined sail. The first such SSK was launched in Wuhan on September 9 last year, and a total of three such SSKs are on order from China’s PLA Navy as well. The AIP system for the Qing-class SSK was developed by the 711th Research Institute of CSIC. R&D work began in June 1996, with a 100-strong team of scientists and engineers led by Dr Jin Donghan being involved in developing the Stirling-cycle engine, while another team led Professor Ma Weiming of China’s Naval Engineering University began developing the all-electric AIP system. The two projects entered the production engineering stage in 2007, with the Shanghai Qiyao Propulsion Technology Ltd, a wholly owned subsidiary of the 711th Institute, becoming the principal industrial entity charged with producing the AIP system. Incidentally, the Qing-class SSK’s all-electric propulsion system is a derivative of a similar system that was developed about a decade ago for the PLA Navy’s six Type 093 Shang-class SSGNs and three Type 094 Jin-class SSBNs.

    The submarine-launched CJ-10K LACM has been developed by the China Aerospace Science and Industry Corp’s (CASIC) Hubei-based Ninth Academy (also known as the Sanjiang Aerospace Group, or 066 Base) on cooperation with the Third Academy’s Beijing-based Xinghang Electromechanical Equipment Factory (159 Factory). Final assembly of the CJ-10K is undertaken by the Beijing-based Hangxing Machine Building Factory (239 Factory). The CJ-10K features an imaging infra-red optronic system for terminal homing, and it makes use of a ring laser gyro-based inertial navigation system combined with a GPS receiver to receive navigational updates from China’s ‘Beidou’ constellation of GPS navigation satellites.

    In another development, during Pakistani Prime Minister Yousuf Raza Gilani’s four-day official visit to China beginning May 17, the decks were cleared for the Pakistan Navy to acquire for a 10-year lease period the two Jiangkai I-class Type 054 guided-missile frigates (FFG) Ma’anshan (FFG-525) and Wenzhou (FFG-526), which have been in service with the PLA Navy’s East Sea Fleet since 2005 (see FORCE December 2010, pages 44-46).
