U.S. Marines' Resupply Drone Undergoes Field Assessment Our Bureau 354 Survice Engineering’s TRV-150 Tactical Resupply Unmanned Aircraft System The Marines assessed a two prototypes of Tactical Resupply Unmanned Aircraft System (TRUAS) in March at Yuma Proving Ground, Arizona. The prototypes were identified by a successful prize challenge in last year. Anticipated future end users were given the opportunity to work with both prototype systems – Survice Engineering’s TRV-150 and Chartis Federal’s MK4-RX – to assess the capability in order to inform the final requirement for TRUAS, Naval Air Systems Command (NAVAIR) said in a statement. The prototypes were designed to meet the Marines initial requirements for an autonomous unmanned system that can transport at least 60 pounds of cargo in various configurations commonly found in Marine company/platoon/squad resupply operations (ex: 5-gallon water can, ammo can/case, Meals-Ready-to-Eat case) through a 10-kilometer radius.
