The $28 million order from the U.S. Army TACOM Life Cycle Management Command calls for 194 general troop transport vehicles. The contract extension runs through December and has a ceiling of $83 million to allow for additional vehicle orders and support packages.
"Supporting the Afghanistan Security Forces has been one of our initiatives since 2005 and it is essential for our nation's success," Navistar Defense President Archie Massicotte.
"Today we have nearly 12,000 Navistar vehicles serving in security and rebuilding missions with Afghan forces. All of those vehicles leverage our current commercial platforms and we'll continue to support those units throughout their 15-20 year lifecycles."
Under the delivery order, Navistar will provide general troop transport vehicles based on the International 7000-MV, or WorkStar, platform as well as parts. Other variants being used in Afghanistan include wreckers, water tankers and fuel trucks.
Production will occur at the company's Garland, Texas, and West Point, Miss., assembly facilities.
