Chinese Have a Missile that Can Sink a Carrier By Itself

It's the new Dong Feng. Specs: Low radar signature, advanced navigation system (read: ability to zig zag and fly low), a warhead big enough to sink a carrier, and a top speed of mach 10. Have I been out of the loop that long? Since when have missiles traveled at Mach 10? The AIM-9 sidewinder, admittedly air-to-air, has a top speed of just Mach 2.65. The Patriot ground-to-air has a top speed of Mach 5 - same as the missiles it is intended to shoot down. Also, how much zig-zagging do you need to do at that speed? How much can you do?
