Could China make a sea-skimming hypersonic missile a real nightmare for the US?

A Chinese hypersonic missile faster than five times the speed of sound, racing just above the sea surface, while staying below the radar horizon. Could this be a new nightmare for the US Navy? Possibly, if a new ambitious low-altitude hypersonic flight research programme launched by the Chinese Academy of Sciences (CAS) on Monday yields results. The programme will look into the technology that could support the development of such weapons. The project, funded under CAS’ Stable Support Programme.
