Artist drawings for China’s JH-XX supersonic stealth bomber appeared on the May 2018’s Aerospace Knowledge magazine cover. Aerospace Knowledge is China’s leading aviation magazine.
The supersonic stealth bomber appears to be following Russia’s TU-160 or the US B1-B bombers.
Nextbigfuture expects that China will build both a subsonic H-20 long-range stealth bomber like the US B2 and a supersonic JH-XX bomber.
Office of the Secretary of Defense – Annual Report to Congress: Military and Security Developments Involving the People’s Republic of China (106 pages) expects China to have new stealth bombers by 2025.
