I’m not sold on this particular representation. Its dimensions don’t seem to fulfill those necessary for even a regional, let alone a strategic, bomber. As I’ve suggested before, I think the PLAAF needs a platform with a 2500 mi combat radius and a 20,000 kg payload, and this depiction, to me, doesn’t suggest that capability.
This is supposedly named "H-18", its more of a tactical bomber, not H-20 which is the strategic bomber.
The "H-18" design was previously revealed in exhibitions. Going by rumours, the H-18 program's future is uncertain.
I think H-20 strategic bomber on the other hand is a better kept secret and its likely that its design hasn't been revealed to the general public. Chinese military commentators on TV had talked about 10,000 km (6200 miles) + range for the future strategic bomber but that is speculation. It is unlikely the magazine cover is referring to the strategic bomber itself as the section that talks about that bomber uses another plane as the filler (bottom left panel).
The H-20 is likely to be more similar to this design. 4 engines, 2 rotary bomb bays, flying wing.
