It appears to me that the days of the time-tested Harpoon antiship cruise missile may be numbered. Several years ago, the U.S. Navy adopted the Norwegian-developed Naval Strike Missile (NSM) for use on Littoral Combat Ships (LCSs), giving the LCS significant strike capability.
In a related development, the U.S. Marine Corps is now using the same missile to equip land-based mobile launcher units of Marine Littoral Regiments.
By comparison with the Harpoon, the NSM is slightly faster and has longer range. The Marine use is an interesting potential game changer; the concept is for the Marines to occupy islands in the Pacific and use the planned medium landing ships (LSMs) to reposition Marine units between various islands, making for a difficult targeting problem for a potential Chinese adversary.
