MaxxPro Dash MRAP (Mine Resistant Ambush Protected) (3E)

Happy GURPSDay!

I certainly can’t take credit for the following vehicle write-up, but I wanted to share for those who may not  have seen this over at the sjgames.com GURPS forum.  Originally written by Phaelen Bleux, I added a bit more information.  By the way – his website has some great 3E modern vehicles that I plan on using!

International MaxxPro Dash MRAP

As U.S. troops continued to fight a battle against guerrilla tactics in Iraq, it was rapidly discovered that the HMMWV was severely susceptible to mines, improvised explosives, and sneak attacks. While attempts were made to improve the protection offered by a HMMWV, the U.S.M.C. began pursuing the Mine Resistant Ambush Protected (MRAP) vehicle program. The key to the vehicle is a V-shaped armored crew compartment mounted on a high-clearance chassis. The APC’s height from the ground reduces the force of the blast from a mine or IED, while the V-shape to the hull defects the blast and fragmentation away from the crew inside the vehicle. One criticism of this design is that the chassis is not as well protected, potentially trapping the crew in a hostile zone with no way to escape. The compartment is armored on the sides and top from ballistic fire as well, and additional armor packages can be added as desired based on mission parameters.

The MaxxPro has a crew of two and can carry 4 passengers plus a gunner (if a gun mount is installed). It can be armed with a 7.62mm (M240B – see p. HT120) or 12.7mm (M2 Browning – see p. HT119) machine gun, or with a Mk19 Automatic Grenade Launcher (see p. HT121). It burns 9.8 gallons of diesel per hour of routine usage. A full tank of fuel costs $102.

The MaxxPro Dash is a smaller version of the original Category 1 vehicle. Its decreased size allows it to be lighter, smaller and more mobile that its larger versions, as well as less prone to roll-over incidents.

Subassemblies: Body +4, full rotation Open Mount -1, 4 off-road wheels +2.
Powertrain: 280-kW improved all-wheeled drivetrain with 280-kW improved diesel engine, 8,000-kWs lead acid batteries.
Fuel: 85 gallons diesel in standard tank (Fire 9).
Occupancy: 2 RCS, 6 RPS.
Cargo: 85 cf.

Armor
Body: 6/130 U *
All Else: 4/65

*Passenger compartment only – engine compartment is rated at 4/65.

Equipment:
Body:

• Single Channel Ground and Airborne Radio System (SINCGARS) Short-range radio with scrambler (4 miles);
• military GPS (either the older AN/PSN-11 PLGR or Precision Lightweight GPS Receiver, or the newer AN/PSN-13 DAGR or Defense Advanced GPS Reciever);
• 10-man NBC kit;
• 16,000-lb. winch with 800-yard cable;
• First Aid Kit (good for three uses, provides +1 to First Aid skill).

Also, soldiers tend to stow various stuff in their vehicles (from tools to rations and everything in between).  It would not be surprising to find various items that the occupants have scrounged and squirreled away in their vehicle.

Statistics:
Size: 20½’x8½’x9′ Payload: 11,000 lbs. Lwt.: 49,000 lbs.
Volume: 936 cf. Maint.: 37 hours Price: $314,260

Ground Pressure: Very High. 1/6 Off-Road speed.

Design Notes:
Body is 780 cf; wheels are 156 cf. Structure is Heavy, Standard. It has improved suspension, improved brakes and run-flat tires (DR 3). Sealed. Armor is standard metal with 90-degree slope on the bottom. Mechanical controls. Design curb weight is 34,937; this matches the historical curb weight of 34,000 lbs. nicely. Calculated gSpeed was 61 mph. Design loaded weight was raised 7%; the cargo space is treated as heavy (100 lbs./cf.). Unit cost in 2009 was $716,000.

Variants:
The MaxxPro (MRAP Category 1) is a slightly larger version.
The MaxxPro Plus features a larger engine and payload.

Future Projects:

By the way, I am working on some write-ups of current US and foreign military UAVs – primarily those used directly by small combat groups.
