Navistar Defense, Warrenville, Ill., was awarded two new contracts by the U.S. Army, increasing sales of medium tactical vehicles to nearly $92 million.

The contracts are extensions to earlier military awards for medium tactical vehicles and other variants of the company's International 7000 Series trucks. Navistar will provide 400 cargo trucks with increased payload, worth nearly $70 million, and 120 tractor-trailers, valued at approximately $22 million.

The vehicles will be delivered to the U.S. Army Tacom Life Cycle Management Command for use in Iraq and Afghanistan. The cargo trucks will be built on the International 7400 Series platform and will have increased engine power and crew seating, as well as increased body length and payload. The award calls for three deliveries, the first of which will be approximately 150 units to be delivered in early 2009. The vehicles will be powered by MaxxForce D 8.7L engines, which are a part of the same family of engines that power the International MaxxPro Plus.

Under the second contract, approximately 120 International 7600 Series tractor-trailers, with Cummins ISM engines, will be delivered to Tacom.

Navistar will supply all required spare parts necessary to support several years of scheduled maintenance for both contracts.
