Guizhou WS-13

The WS-13 (Chinese: 涡扇-13), codenamed Taishan, is an afterburning turbofan engine designed and manufactured by Guizhou Aircraft Industry Corporation. It was originally developed to power the CAC/PAC JF-17 Thunder, a lightweight multirole fighter jointly developed by China and Pakistan. Improved variants of the WS-13 have also been developed to power the Shenyang J-35 fifth-generation stealth fighter, while the latest versions are intended to equip advanced variants of the JF-17 Thunder, including the Block III (often described as a 4.5-generation fighter).
