The US Army is conducting Military Utility Assessment (MUA)
of five demonstration trucks built under a US$60 million technology
evaluation program known as "Future Tactical Truck System"
(FTTS). The test involving vehicles developed by Lockheed Marin,
International Trucks and Armor Holdings (formerly Stewart &
Stevenson) include three utility vehicles and two maneuver sustainment
vehicles (MSV). During the evaluation, the vehicles are operated
by troops of the 5th Brigade, 2nd Infantry Division, and the
14th Engineer Battalion at Ft. Lewis to assess their military
performance.

The 18,500 pound (8.39 ton) tactical utility vehicle is the
smaller vehicle, built by International. It is powered by a
hybrid-electric engine, positioned in the rear, clearing more
room in the cab. The vehicle used four-wheel steering for enhanced
maneuverability, including driving sideways. The vehicle is
fitted with a remote weapons system.
A larger, 25,000 pound (11.34 ton) vehicle was built by Lockheed
Martin. This vehicle offers an articulated drive, adjusting
the vehicle's height, and a tilt system enabling the truck and
trailer to travel over rough terrain. The vehicle is designed
with a V-shaped hull designed to deflect IED blasts. It has
a top road speed of 75 mph.

Armor
Holdings developed the Maneuver Sustainment Vehicle (MSV) comprising
a hybrid electric drive that can deliver up to 30 kilowatts
of exportable power. Each wheel is powered by a new 120kW electrical
motor made by UQM. The vehicle is also equipped with a fully
robotic crane that can lift 13 tons of cargo and remotely operated
weapon station.
