WARRENVILLE, Ill. (April 17, 2008) Armor upgrades to Mine Resistant Ambush Protected (MRAP) vehicles will provide U.S. troops with a tougher defense against evolving explosive threats. Navistar Defense, LLC won a contract valued at more than $261 million from the U.S. Marines for engineering upgrades to the armor used on International® MaxxPro™ MRAP vehicles. Navistar Defense, formerly known as International Military and Government, LLC, is a wholly owned affiliate of Navistar International Corporation (Other OTC: NAVZ).

Under the new contract, armor protection on production MaxxPro MRAP vehicles will be increased to that of the MaxxPro Plus protection level.

MaxxPro MRAP vehicles are designed to protect troops from roadside bombs and other threats. To date, the military has ordered 5,214 total production MaxxPro MRAP vehicles.

“Our close collaboration with the U.S. military allows us to swiftly adapt our vehicles to meet the growing threats and challenges faced by our troops in theater,” said Archie Massicotte, president of Navistar Defense. “It is a privilege to build and service the MaxxPro MRAP vehicles because this is about protecting our troops so they can fulfill their missions safely.”
