WARRENVILLE, Ill. (April 30, 2009) - Navistar Defense, LLC today received a contract to deliver three test units for the next round in the U.S. Army’s Mine Resistant Ambush Protected (MRAP) All Terrain Vehicle (M-ATV) program. It is anticipated that production awards for the program could total volumes between 2,080 and 10,000 units.

Navistar remains dedicated to the rapid delivery of these vehicles and stands ready to immediately begin producing large quantities of M-ATV units upon the Government’s direction.

“Navistar’s participation in the M-ATV program is a privilege,” said Archie Massicotte, president, Navistar Defense. “We are dedicated to the warfighters and we will work with the military to ensure those in Afghanistan receive the very best vehicles as quickly as possible.”

With more than 100 years of manufacturing and engineering experience, Navistar is able to rapidly start up new vehicle production to support those serving in harm’s way. Since 2007, Navistar has delivered more than 6,000 MRAP vehicles and has also responded to evolving in-theater threats by modifying its design to produce six MRAP variants, each with significant armoring design changes, during the first 18 months of the program. In February, the military celebrated the fielding of its 10,000th MRAP unit.

“Navistar has long been designing its commercial work trucks, in mass quantities, on a per-customer basis as its core business,” said Massicotte. “Designing products for the military is no different.”
