With two UGVs astronomically apart in weight classes, the U.S. Army is working on requirements for a middle-ground platform called MMET.
After the 1000 lbs-carrying SMET and 50000 lbs-capable autonomous PLS trucks, the service has concluded that a medium platform is needed, Breaking Defense reports. While the payload capacity is yet to be decided, the medium platform may be comparable to a 4x4 tactical vehicle in terms of capacity.
Oshkosh has developed an unmanned JLTV 4x4 vehicle as a launch platform for NSM cruise missiles. JLTV's widespread use by the U.S. Army makes adopting the unmanned version as a medium logistics vehicle highly likely.
The baseline JLTV can carry a payload of 5100 lbs, and the lighter unmanned version can carry slightly more, fitting the required middle ground. Currently, UGVs are used by a few countries for logistics missions before their eventual adoption in armed configurations.
The lack of engagement parameters simplifies this mission more than armed patrolling or fire support. The payload in the hundreds of kilograms range can lighten the load on soldiers when it comes to carrying ammunition, food, or medical supplies.
