China is building the world’s fastest wind tunnel to simulate hypersonic flight at speeds of up to 12 kilometres per second.

So...26,800 mph? That's above mach 25 and the speed at which objects reenter the atmosphere from space. Assuming it didn't burn up from the friction, you wouldn't even need a warhead on such a device.
Let's just say I find it difficult to believe that a projectile could effectively sustain such speeds without catastrophic results.

The US military tested HTV-2, a Mach 20 unmanned aircraft in 2011 but the hypersonic flight lasted only a few minutes before the vehicle crashed into the Pacific Ocean.
