China has engineered a new class of hypersonic missiles using advanced stainless-steel alloys capable of surviving temperatures above 3,800°C — conditions created when flying at more than five times the speed of sound. This breakthrough material science allows the missile to remain stable, aerodynamic, and structurally intact even under extreme heat and pressure. It marks a major leap in hypersonic weapon durability and long-range performance. • Traditional missile materials melt or deform at hy
