WARRENVILLE, Ill. (December 21, 2011) - Navistar Defense, LLC today announced that it received a $134 million delivery order for field service representatives (FSRs). The order from the U.S. Marine Corps Systems Command renews the company’s in theater FSR service contract to support International® MaxxPro® Mine Resistant Ambush Protected (MRAP) vehicles.

“I’m proud to say that Navistar will not sell a truck if we can’t support it in theater,” said Archie Massicotte, president, Navistar Defense. “Sustainment of our vehicles is key – especially when vehicle lifecycles may run between 15 to 20 years. With our fleet of vehicles now growing beyond 32,000 trucks, fleet support will continue to be a critical piece of our business.”

The company currently has more than 600 FSRs in theater and working domestically to support the MaxxPro family of vehicles.

Work conducted under the renewed contract will run through December 2012.
