China to supercharge J-20 stealth fighter with new radar, engines, AI

China is set to upgrade its J-20 stealth fighter with enhanced avionics, new engines, and artificial intelligence (AI) integration, marking a significant step in the aircraft’s development as it celebrates 15 years since its first flight. The J-20, developed by Chengdu Aircraft Corporation and in service since 2017, is a key component of China’s military modernization and a counter to advanced US stealth fighters like the F-22.

Engine upgrades have progressed from Russian Saturn AL-31 models to China’s domestically produced WS-10C and now the more powerful WS-15, which offers better thrust and high-speed performance. AI integration is anticipated to serve
