For the time since December 1941, when Wake Island’s shore gunners sank the invading destroyer Hayate, Marine Corps artillery wants to kill ships. That could be a big boost for the Navy, which confronts ever more powerful Russian and Chinese fleets.
Army artillery is also exploring anti-ship missiles, and the Marines may buy the same one. The difference is that it’s the Marines who work most closely with the Navy and who land in hostile territory to seize forward bases to support the fleet. That role makes Marines the first choice for the first wave, while the larger but slower Army provides backup.
