The official did not specify the supply chain problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The WS-19 afterburning turbofan is under development to power the Shenyang J-35, a next-generation fighter jet meant to operate from aircraft carriers for China\u2019s People\u2019s Liberation Army Navy. The WS-20 is a high-bypass turbofan engine that will power the <a href=\"https:\/\/www.defensenews.com\/global\/asia-pacific\/2021\/02\/18\/satellite-images-suggest-chinas-new-tanker-aircraft-is-under-production\/\" target=\"_blank\">Xi\u2019an Y-20 airlifters<\/a> operated by the People\u2019s Liberation Army Air Force.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Y-20 is currently powered by <a href=\"https:\/\/www.defensenews.com\/air\/2022\/02\/14\/russias-defense-aircraft-sales-prosper-but-is-it-losing-its-biggest-regional-customer\/\" target=\"_blank\">the Russian D-30KP low-bypass turbofan<\/a>, which is also used by the Xi\u2019an H-6J\/K\/N bombers of both armed services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Zhang also confirmed that the WS-15 afterburning turbofan is ready for mass production. The engine will be used for later variants of the Chengdu J-20 stealth fighters of the PLAAF.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The WS-15, rated at 181 kilonewtons, is expected to provide a supercruise capability for the J-20, enabling it to attain supersonic cruise speeds without the use of its afterburner, which reduces fuel consumption.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Zhang also said at his presentation that China managed to achieve \u201c98% localization\u201d for the WS-10C engine, which is powering the J-20s currently being delivered to the PLAAF. Other variants of the <a href=\"https:\/\/www.defensenews.com\/air\/2022\/11\/28\/footage-shows-domestic-engine-on-chinas-j-15-fighter-jet\/\" target=\"_blank\">WS-10<\/a> equip China\u2019s <a

fleets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">He did not provide details on the remaining 2% input, although it\u2019s likely related to components or materials China still sources from foreign providers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>China has completed the development of its next generation of indigenous military aircraft engines and is preparing to start mass
