Overview

The Pratt Miller EMAV (Expeditionary Modular Autonomous Vehicle) is a tracked, hybrid unmanned ground vehicle from Pratt Miller Defense, an Oshkosh Corporation subsidiary, offering a silent-watch capable hybrid powertrain and both teleoperated and autonomous operating modes. The deck measures roughly 3.84 m by 1.5 m and carries up to about 3,265 kg of payload; mobility figures include a 60 percent grade climb, 40 percent side-slope capability, a 60 cm vertical step climb and 28V/320V exportable power for onboard systems. In its armed EMAV-MCA configuration, the platform has been demonstrated mounting a Rafael Samson MCWS 30mm remote weapon station, which was live-fired in October 2021. EMAV remains a prototype/demonstrator platform rather than a program of record.

Full specifications

Performance

Speed, range, altitude and engagement capability.

Performance specifications
Max speed Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.	72 km/h Stronger than 87% of UGVs

Physical

Dimensions, weight and crew.

Physical specifications
Length Overall length including gun/probe where applicable.	3.84 m
Width Overall width, matters for rail/road transport of vehicles.	1.5 m
Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.	0
Cargo payload Maximum cargo the transport can carry. Higher means more lift per sortie. On an unmanned ground vehicle, this is the maximum mission payload the platform carries, including a weapon station.	3,265 kg Stronger than 85% of UGVs

Propulsion

Engine, power and fuel.

Propulsion specifications
Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…	Hybrid, silent watch capable

Autonomy & control

How the platform moves, how much it does without an operator, and how far the control link reaches.

Autonomy & control specifications
Locomotion How the platform moves: tracked, wheeled or legged. Tracks suit soft ground and heavy payloads, wheels favor road speed and range, legs handle stairs and rubble. Not a ranking, a trade-off.	Tracked
Autonomy level How much the platform does without an operator, as the manufacturer describes it. Vendors do not use a common standard, so this is a coarse editorial bucket, not a certified rating.	Semi-autonomous
