The WS-10 was derived from the WS-6 turbofan, which was abandoned at the start of the 1980s. The WS-10 project was reportedly started by Deng Xiaoping in 1986 to produce an engine comparable to the AL-31. The work was given to the Shenyang Aeroengine Research Institute (606 Institute) of Aviation Industry Corporation of China (AVIC). The WS-10 may have been based on the core of the CFM-56II (itself based on the General Electric F101); China purchased two CFM-56IIs in the 1980s. China may have spent nearly 20 years developing source code, after being unable to purchase code from Salyut.
The WS-10A, targeted for 130 kilonewtons (29,000 lbf) of thrust, was already in development in 2002. An early version was flown on an J-8II in 2002. In 2004, Russian sources familiar with project reported problems meeting the thrust target; in 2005, they reported problems reducing the weight of the primary and secondary compressors, in addition to problems meeting thrust requirements. Engine testing on the J-11 had already started by 2004, and testing using one engine on the J-11 may have occurred as early as 2002.
A full-scale WS-10A engine was first seen at the 2008 China International Aviation & Aerospace Exhibition.
In 2009, Western media reported that the WS-10A approached the performance of the Saturn AL-31, but took much longer than the AL-31 to develop thrust. Furthermore, reportedly the engine only generated 110–125 kilonewtons (25,000–28,000 lbf) of thrust. In April 2009, Lin Zuoming, head of AVIC, reported that the engine's quality was unsatisfactory. In 2010, it was reported that reliability was also poor; the WS-10A lasted only 30 hours, while the AL-31 needed refurbishing after 400 hours. The quality problems encountered with the WS-10A reflected the state of the Chinese aerospace industry; AVIC initiated a general effort to improve quality control throughout its production chain in 2011.
The WS-10A reportedly matured enough after 2009 to power the J-11B Block 02 aircraft. A WS-10A-powered J-10B was seen in July 2011, but the engine did not power the initial J-10B production batch, possibly because of production or performance issues.
Unconfirmed reports claimed the first flight of the J-11D was powered by a new WS-10 variant; the variant reportedly had improved reliability, with a thrust of more than 13t, and less than that of the AL-31F-M1. The flight was revealed in early May 2015.
