3. ARK mission
• To provide the civil emergency plans Authorities and
Landing Forces with a Logistic Amphibious Tracked
Vehicle (LATV) suitable to increase their intervention and
projection capability, to satisfy the requirements and
duties of search and rescue mission. It can be used as an
ambulance to to provide emergency and medical services,
access and transportation to blockaded villages and to
supply them with any kind of supplies.
• It will also carry out rescue operation in case of natural
catastrophic events. Capable to run in marine, lagoon,
river and mountains, also in snow environment. With
suitable fire fighting kit, it can be used also for fire fighting
missions.

4. Design criteria 1
•Add amphibious capability to the very reliable and
all over the word proven M548, adding:
• good navigation performance,
• high stability into water,
• same performance on ground of the original M548.
•Obtain an amphibious vehicle that can operate not
only in sea and in shoreline environment, but can
also operate on road, railways, mud and marsh with
a good loading capability.

5. Design criteria 2
Using this hierarchy, A.R.I.S. engineering
ARIS designers used the developed simple and effective solutions:
following priority principles: A keel to improve the buoyancy and to
reduce the water (wave) drag.
1 - MOBILITY Two ducted propellers driven by
hydrostatic motors, that can be
2 - LOADING CAPABILITY independently actuated and also
reversed for in-water direction control.
3 – COST Two hydraulic pumps to actuate a.m.
hydrostatic motors.
Increased trust at fixed point into water has
been obtained installing in the rear part, two
additional propellers, making it easier to
come out from water and get afloat stranded
ship.
