China will be building them based on the Ukrainian design, presumably with Chinese engines and equipment. The question is: why? What ginormous payloads do the Chinese think they’ll need modernized Mriyas for? The An-225 was designed to carry the Soviet “Buran” space shuttle orbiter on its back… *perhaps* the Chinese are thinking of doing the same thing. Feel free to speculate.
The article suggests the Chinese believe that the first of an unspecified number of new AN-225’s will fly in 2019… only three years away. That’ll be a neat trick, unless the Chinese have been working away at this for a while, or are going to work themselves to death to get it done, or are going to half-ass certain aspects of the process. I wouldn’t bet against any of those.
