International MaxxPro

The International MaxxPro MPV is an armored fighting vehicle designed by Navistar International's subsidiary International Military and Government LLC (IMG) along with the Israeli Plasan Sasa, who designed and manufactures the vehicle's armor. The vehicle was designed to take part in the US Military's Mine Resistant Ambush Protected vehicle program, led by the US Marine Corps, as well as a similar Army-led program, the Medium Mine Protected Vehicle. Three variants are produced: a smaller Category 1 vehicle, a larger Category 2 MaxxPro XL, and the MaxxPro Plus that includes increased EFP protection. All three versions share a common platform.

Design
The MaxxPro utilizes a crew capsule with a V-shaped hull, mounted on an International WorkStar 7000 chassis. The V-hull deflects the blast of a land mine or improvised explosive device (IED) away from the vehicle to protect its occupants. Because the chassis is mounted outside the armored crew capsule, there are concerns that it will likely be destroyed in the event of an ambush, leaving the soldiers inside stranded. However, according to Navistar spokesperson Roy Wiley, the MaxxPro "did extremely well during the tests, and we are extremely pleased." This design may prove as effective as the Krauss-Maffei Wegmann ATF Dingo that uses a similar design, one which mounts an armored capsule to a Unimog chassis. This design has survived a 7kg (15 lb) land mine blast with no injuries.

On 2008-01-19 a 3rd Infantry Division U.S. Army soldier, an exposed turret gunner, was killed in a Navistar MaxxPro MRAP vehicle by an ANFO IED estimated at 600lbs. It is unknown whether the gunner was killed by the explosion or by the vehicle when it rolled over after the blast. However, the vehicle’s v-hull was not compromised. The crew compartment also appeared to be uncompromised in the attack, and the three other crew members who were all inside the vehicle survived; one with a shattered left foot, a broken nose and several broken teeth; the driver with a fractured foot; and the third was unhurt and returned to duty the following day.

According to IMG, the vehicle is designed with operational readiness in mind and utilizes standardized, easily available parts, to ensure rapid repair and maintenance. The armored body is bolted together instead of welded, as in other MRAPs. This facilitates repair in the field and is a contributing factor to Navistar's greater production capacity for the MaxxPro.

MaxxPro Plus
On June 16, 2008 Navistar debuted a new version called MaxxPro Plus. MaxxPro Plus has increased engine power and payload, as well as Frag Kit 6 enhancements for increased explosively formed penetrator protection.

MaxxPro Dash
On September 4, 2008 the U.S. Marine Corp. awarded Navistar a $752 million contract to develop and produce a lighter, smaller, and more mobile MaxxPro variant that is less prone to the rollover problems that have plagued MRAP vehicles. MaxxPro Dash has a smaller turning radius and higher torque to weight ratio. Production of the MaxxPro Dash will begin in October 2008 with delivery of 822 units to be completed by February 2009.
