Tomahawk, Patriot, and countless ICBM's developed in the 40/50/60's tell me that America has had this kind of ability for a long time.
Just look at the guided bombs and space missions for precise guidance systems.....
American strategy has been to use air power to take out shipping and other targets, Tomahawk and Harpoon are the only real dedicated anti ship missles the yanks have used.
If the Chinease have this weapon then the Americans have one or a defensive capability for it.
The American Military may be the butt of jokes because of the grunts on the ground, but never underestimate them or their ability to achieve.
