In late December 2016, the Hong Kong newspaper Ming Pao reported that the People’s Liberation Army (PLA) planned to initially acquire up to 100 J-20A variants, expected to be powered by an advanced version of the WS-10 or the AL-31 engine.
Ming Pao also reported that the PLA would then purchase up to 400 of J-20B version, expected to be equipped with a turbofan thought to generate a thrust of 145 kN, enabling a ‘super-cruise’ speed capability without afterburner.
