The Great Hypersonic Race
John A. Tirpak
China, the US, and Russia are each striving to be the first nation to develop hypersonic systems: aircraft and missiles that can cruise and maneuver at five times the speed of sound (Mach 5) or faster. The winner of this technology contest will have daunting military advantages. Such weapons promise the ability to hit targets from very long ranges, yet with such speed and surprise that defending against them is extremely difficult.
