Naval NewsMarines Deploy Anti-Ship and Counter-Drone Systems to Okinawa
The 12th Marine Littoral Regiment on Okinawa has taken custody of two new weapons systems: the Navy-Marine Expeditionary Ship Interdiction System (NMESIS) and the Marine Air Defense Integrated System (MADIS). NMESIS is a remote-controlled, ground-based anti-ship platform firing Naval Strike Missiles with a range of up to 115 miles, described by CSIS expert Mark Cancian as the 'backbone' of the Marine Littoral Regiment. MADIS provides counter-drone and low-altitude air defense. The deployment is part of the Marine Corps' Force Design Initiative aimed at preparing for large-scale island-hopping campaigns against China. The systems' mobility and concealability offer advantages over vulnerable surface ships. The 3rd Marine Littoral Regiment in Hawaii first received these systems in late 2024 and has used them in exercises in Japan and the Philippines.
