A Caliber Missile and in a Rush?

Crews missiles can carry a warhead that's up to 500 kilograms of explosive or a nuclear warhead. They are twice as heavy and almost four times as fast as an american tomahawk crews missile, which gives it like a huge kinetic potential. And they flies at two mock two point nine, which means that it can't really be intercepted by existing missile defense systems either. It's just too damned fast.
