WASHINGTON — April 28, 2026 : American Rheinmetall presented a coordinated suite of unmanned logistics systems and next-generation infantry weapons at the Modern Day Marine 2026, held from April 28 to 30 at the Walter E. Washington Convention Center. The company’s exhibit focused on systems designed for squad- and platoon-level operations, emphasizing autonomous resupply, expeditionary deployment compatibility, and increased individual lethality.
The display at Booth 1907 combined multiple platforms into a single operational concept, highlighting how unmanned ground systems and advanced weapons can be integrated within small Marine units operating in dispersed and littoral environments. The systems presented are configured to minimize additional training and infrastructure requirements, aligning with expeditionary use cases.
Amphibious Autonomous Logistics Platform
The central platform on display was the Mission Master Silent Partner Hotel (MMSP-H), part of the broader Rheinmetall Mission Master family of autonomous uncrewed ground vehicles. The MMSP-H is manufactured in the United States and is designed to operate across both land and water without requiring configuration changes or separate transport systems.
The vehicle has a payload capacity of 2,200 pounds on land and 880 pounds when operating afloat. Its amphibious capability is intended for Marine Corps missions involving ship-to-shore movement, beach landings, and operations across water obstacles. The system can transition directly between terrain types, maintaining continuity in logistics operations.
The MMSP-H holds certification from Naval Air Systems Command, confirming compliance with airworthiness and safety requirements for aviation-related operations. This certification enables multiple insertion methods, including external sling-load transport under heavy-lift helicopters such as the CH-53K King Stallion and parachute delivery into operational areas. The platform is also compatible with internal transport in rotary-wing aircraft.
The vehicle incorporates an electric drive system and is designed with reduced acoustic and thermal signatures. These features support its use in contested environments where detection risk is a factor. Its operational roles include logistics resupply, casualty evacuation, reconnaissance, and surveillance.
Testing and evaluation activities involving the Mission Master platform family have been conducted by U.S. Marine Corps units in multiple locations, including Okinawa, Japan, and at the National Training Center in California. Exercises included casualty evacuation scenarios with the 4th Marine Regiment, validating the platform’s use in expeditionary conditions.
Fielded Unmanned Resupply System
Also presented was the “Wild Goose” unmanned logistics system developed by Marom Dolphin Ltd.. The system represents a fully fielded platform with a Technology Readiness Level (TRL) of 9, indicating operational use and maturity.
Wild Goose is designed for short-range resupply missions at the tactical level. It can carry payloads of up to 330 pounds and has an operational range of approximately 25 kilometers. The system is electrically powered and configured for mobility across varied terrain conditions.
The platform is compatible with multiple military transport systems, including the Infantry Squad Vehicle (ISV), High Mobility Multipurpose Wheeled Vehicle (HMMWV), Joint Light Tactical Vehicle (JLTV), and the UH-60 Black Hawk. It can be transported internally or externally depending on mission requirements.
A key feature of the system is its door-bundle deployment capability, which allows it to be pushed from a helicopter during flight as part of an airborne resupply operation. This method does not require specialized delivery equipment or a dedicated aircraft, enabling rapid deployment in austere environments.
Squad-Level Precision Weapon System
The third system showcased was the Highly Advanced Multi-Mission Rifle (HAMMR), a magazine-fed, semi-automatic 40 mm grenade launcher derived from Rheinmetall’s Squad Support Weapon 40 (SSW40) architecture.
The HAMMR is designed to provide squad-level precision fires and is compatible with both low-velocity and medium-velocity 40 mm ammunition. It uses 3-round and 5-round detachable box magazines and is capable of firing programmable airburst munitions.
The system integrates with the Aimpoint FCS15 fire control system, enabling target calculation and munition programming via an infrared interface. This allows engagement of targets behind cover and at extended ranges, increasing first-round hit probability. The HAMMR is also compatible with existing U.S. Army standard 40 mm low-velocity ammunition.
The weapon is positioned for consideration in programs such as the Precision Grenadier System, reflecting ongoing efforts to enhance infantry capabilities at the squad level.
Operational Integration and Marine Corps Context
The systems presented by American Rheinmetall align with the U.S. Marine Corps’ ongoing efforts to expand the use of unmanned platforms in ground operations. By integrating autonomous logistics platforms such as the MMSP-H and Wild Goose, units can reduce reliance on manual resupply and limit exposure during transport tasks.
At the same time, the introduction of systems like the HAMMR supports increased firepower and precision at the individual Marine level. The combination of these capabilities is intended to extend operational reach, support distributed operations, and improve efficiency in environments where traditional logistics and support structures are limited.
The company’s presentation at Modern Day Marine 2026 demonstrated how these systems can function together within squad and platoon formations, providing a combined approach to logistics and combat capability without requiring large-scale system integration.
