Navistar Defense, LLC , has received an $880 million delivery order from U.S. Marine Corps System Command for an upgrade on 2,717 International MaxxPro Mine Resistant Ambush Protected (MRAP) vehicles.

The vehicles will be retrofitted with a new rolling chassis. Navistar's rolling chassis solution will improve the MaxxPro's off-road capability with the addition of independent suspension and a MaxxPro 9.3-liter engine, 570 amp alternator and driveline. The order also includes engineering changes, supplies and services.

"Our rolling chassis solution allows us to leverage our unique vehicle design and replace an older chassis with a new, highly mobile independent suspension chassis," said Archie Massicotte, president of Navistar Defense. "During all this we keep the armored capsule intact while creating commonality through the entire MaxxPro fleet."

"As Defense budgets are being reduced, it is imperative that we continue to develop economical solutions that repurpose assets while also working to ensure warfighters have access to emerging technologies and capabilities," Massicotte said in the release.

Work on the vehicles will begin at Navistar's West Point, Miss., assembly facility in January 2012. Completion is scheduled for October 2013.
