About NMESIS (Navy Marine Expeditionary Ship Interdiction System):
- It is a ground-based anti-ship missile system developed for the US Marine Corps (USMC) to support land-to-sea attacks performed by the US Navy.
- Country of Origin: United States.
- It entered service in 2021, providing the Marine Corps with a critical tool for anti-ship warfare in remote and distributed operational environments.
- It features the US Navy’s latest anti-ship missile, the Naval Strike Missile (NSM), mounted atop the chassis of an unmanned variant of the Oshkosh Joint Light Tactical Vehicle (JLTV).
- The ground vehicle platform, known as the Remotely Operated Ground Unit for Expeditionary (ROGUE) Fires vehicle, is supplied by Oshkosh Defense, United States, while the NSM is jointly manufactured by Raytheon Missiles & Defense (Raytheon), United States, and Norwegian company Kongsberg Defence & Aerospace.
- NMESIS is not considered an autonomous launcher, as its fire control system is not controlled by the self-driving system and autonomy technology.
- The system is operated by a marine who is responsible for mission planning and firing of the missile.
- Features of ROGUE Fires:
- It incorporates advanced autonomous vehicle technologies, off-road mobility, and high payload carrying capacity.
- The vehicle is remotely operated using the teleoperator or leader-follower modes.
- The vehicle lacks a crew cab/body. It is integrated with sensors and cameras, with a launcher mounted atop the vehicle.
- The vehicle has a range of 480-640 km depending on terrain and operational conditions, allowing it to cover large areas in a single mission.
- The flexible design of the platform allows it to be configured to meet different mission requirements.
- Features of NSM:
- It is a multi-mission cruise missile that can ably neutralise highly secure maritime and land targets.
- It has a firing range of approximately 185 km (100 nautical miles), and flies at a subsonic speed of around 0.9 Mach.
- Its multi-mode guidance system incorporates inertial navigation, GPS, and active radar homing.
- The missile’s low radar cross-section makes it difficult to detect, and its sea-skimming flight profile allows it to avoid detection by enemy radar systems.
- It carries a 226.79 kg-class warhead and programmable fuse.
