Can the Pentagon Find a Way to Stop Chinese and Russian Hypersonic Missiles? (Source The national Interest) Hypersonic missiles will be faster than anything yet invented and will be very hard to intercept. This is why all the major powers are racing to build them. The Pentagon is fast-tracking sensor and command and control technology development to improve defenses against fast-emerging energy hypersonic weapons threats from major rivals such as Russia or China, US Missile Defense Agency officials said. Citing particular emphasis upon the area of Command and Control, Battle Management and Communications , Missile Defense Agency Director of Operations Gary Pennett said the Pentagon is working to address “sensor and interceptor capability gaps” exposing potential vulnerability to hypersonic weapons attacks.
