On 13 September 2015, a new prototype, marked '2016', begun testing. It had noticeable improvements, such as apparently changed DSI bumps on the intakes, which save weight, complexity and radar signature. The DSI changes suggested the possibility of more powerful engines being used than on its predecessors, likely to be an advanced 14-ton thrust derivative of the Russian AL-31 or Chinese Shenyang WS-10 turbofan engines, though, by 2020 the J-20 is planned to use the 18-19 ton WS-15 engine, enabling the jet to super-cruise without using afterburners. The trapezoidal flight booms around the engines were enlarged, possibly to accommodate rearwards facing radars or electronic jamming equipment. The fuselage extends almost entirely up to the engine's exhaust nozzles. Compared to its '2014' and '2015' predecessors, the J-20's fuselage contains more of engine's surface area inside the stealthy fuselage, providing greater rear-facing stealth against enemy radar.

In November 2015, a new J-20 prototype, numbered '2017', took to the sky. The most significant change in the new prototype is the reshaped cockpit canopy, which provides the pilot with greater visibility. The lack of other design changes suggest that '2017' is very close to the final J-20 production configuration. Since '2017' is likely the last J-20 prototype, low rate initial production of the J-20 is likely to begin in 2016. It has been reported that the design of J-20 is already mature and will not directly use the 117S engine. At least six J-20s are in active service, with five tail numbers 5 identified.
