Overview

The Viking is a 6x6 diesel parallel-hybrid unmanned ground vehicle prototype developed by HORIBA MIRA and trialled under the UK Ministry of Defence's JTARR programme, including Project THESEUS field trials. Its 200 km diesel-hybrid range includes roughly 20 km of silent, electric-only running, and its autonomy stack is designed to remain functional in GPS-denied environments. This platform is unarmed: no weapon system is fitted or planned, and no firepower specifications apply.

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.	50 km/h Stronger than 65% of UGVs
Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.	200 km Stronger than 42% of UGVs

Physical

Dimensions, weight and crew.

Physical specifications
Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.	2,000 kg
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.	750 kg Stronger than 34% of UGVs

Propulsion

Engine, power and fuel.

Propulsion specifications
Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…	Diesel parallel hybrid

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.	Wheeled
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
