The U.S. Army will demonstrate the "cross domain fires / cross domain integration" concept by firing an NSM against a ship target at sea during the joint exercise taking place in (and off) the island of Hawaii. A contract was awarded to Raytheon for this.
The first mention of this live test came from the Chief of U.S Pacific Command, Amiral Harris, talking at the Association of the United States Army LANPAC Symposium and Exposition last year in May.
"Significant to this audience, during RIMPAC 2018, USARPAC will fire a Naval Strike Missile from the shore to sink a ship." Admiral Harris said at the Army symposium last year.
