Destroyers: Destroy!

Some thoughts on what the Zumwalt-class destroyers might do if Trump and McMaster drag us into war with North Korea:
After the 1991 Gulf War, the U.S. Navy decommissioned its last battleships. The U.S. Marine Corps, among others, argued that the United States still needed gunfire support for amphibious operations, and platforms for long-range attacks against targets in the littoral. The Zumwalt class was conceived in response to this need, as the Navy sought a land-attack warship that could operate with minimal support to disrupt and destroy advancing enemy formations. The keys to this capability were a stealthy design that would preclude attacks against the ships from aircraft and coastal missile installations, a large magazine of land-attack cruise missiles, and the Advanced Gun System, which could theoretically hurl 155-millimeter shells up to eighty miles with tight precision and a high rate of fire.
