AM General M1165A1 HMMWV

In an attempt to expand the utility of the basic M998 High Mobility Multipurpose Wheeled Vehicle, the U.S. armed forces have designed several variants. The M1165 is itself a hybrid of two variants, the four-door M1097A2 and the M1113 ECV (Expanded Capacity Vehicle). The M1165, introduced in 2007, is intended for special ops use as a command and control vehicle. The basic version, or -A1, has an Integrated Armor Package installed in the form of underbody armor.

The M1165A1 carries four soldiers and 3,470 lbs. of cargo. It has a ground clearance of 17" and can ford 30" of water, or 60" with a fording kit installed. The truck burns 5.8 gallons of diesel per hour. Visibility is good.

Mechanical controls. Design curb weight is 7,143 lbs; this was increased 1% to the real-world value. Calculated gSpeed was 80 mph. Real-world loaded weight was used for performance calculations. List price for a basic Humvee is $56,400.

 

Variants:

The M1165A1 with B3 armor upgrade adds 3,320 lbs. of Expensive Metal armor to all sides of the vehicle (rather than just the underbody), increasing DR by 17 (+ 8 = 25 overall). This increases the vehicle's loaded weigh to 12,100 lbs. and reduces cargo capacity to 2,230 lbs. Curb weight is 9,870 lbs.
