There are two components to these aircraft that no one else can duplicate, the optics and the microcircuitry, so I'm unworried about China's current program. That's what's going to take them at least 10 years to catch up to, and they most likely will. Russia will not.
The space shuttle isn't nearly as large or as sleek as most people think it is, there's a decomissioned one at the Kennedy Space Center. The crew area is tiny, most of the space being taken up by the large cargo bay the MIC insisted on. Visit it if you can, it's fascinating.
