to designated points, follow roads
and trails, operate in “come to me”
mode, or follow an assigned person.
According to Lockheed Martin, the
system’s software ensures that several SMSS units can be operated in
close proximity and always follow the
right person. The vehicle can also
be controlled manually via a handheld touchscreen remote. It can also
carry and power a Mobile Network
Integration Kit (MNIK) for network-to-platoon communications.
The SMSS is based on the Land Tamer, a commercial, heavy-duty ATV platform provided by
PFM Manufacturing. Powered by a four-cylinder Kubota V2403-M-T-E3b turbodiesel engine
rated 59 hp, the high-mobility six-wheel drive ATV can carry 1200 lb. of gear in total.

The fully loaded SMSS, weighing
about 2.5 tons, can be sling loaded
under a UH-60L helicopter or carried
internally in a CH-47/53 helicopter.
In the future, the SMSS technology
could be adapted to armed variants
for reconnaissance, intelligence, surveillance and target acquisition, the
company said. dp
It incorporates a hydraulic/gear drive
system based on an Eaton closed-loop variable flow tandem pump system. Each individual pump powers a
set of gearboxes to the wheel axles
on the left or right side located inside
the vehicle’s hull. All wheels on each
side are coupled together to a drive
shaft connecting all wheel axles and
are driven by one Eaton heavy-duty
hydraulic drive motor for each side.
A purpose-built platform optimized for
SMSS mission requirements continues to be developed.
The SMSS also serves as a power
management resource. It can provide up to 4 k W of electrical power,
which is enough to power all vehicle systems plus Perlite six-battery
chargers. In support of the Nett
Warrior system, this is sufficient to
charge 146 batteries within 10 hours,
Lockheed Martin said.
Using a Laser Detection and
Ranging (LADAR) system and obsta-cle-avoidance algorithms, the SMSS
