Could China make a sea-skimming hypersonic missile a real nightmare for the US? (opens original article in a new tab)

A new Chinese research program explores low-altitude hypersonic flight technology that could create missiles faster than five times the speed of sound, potentially challenging US naval defenses by operating below radar detection.

• Chinese Academy of Sciences launches low-altitude hypersonic flight research program
• The program aims to develop technology for hypersonic missiles that fly below radar detection
• Low-altitude hypersonic flight could improve missile penetration of air-defence networks
