Navistar Defense and Tatra Form Strategic Alliance

The new vehicle will utilize Navistar engines and other components in addition to Tatra's proven backbone-tube chassis design and independent suspension system. Tatra's chassis concept was originally developed in 1923 and today uses swinging half-axles for exceptional off-road mobility and added resistance against chassis wear and tear.

"We believe the Tatra chassis is the most capable off-road suspension system available anywhere in the world," said Archie Massicotte, president, Navistar Defense. "By joining with Tatra, the team is positioned well to compete for new vehicle programs with U.S. and Allied Forces. Upcoming opportunities include the Israel Medium Tactical Truck (MTT) and Canada 10 x 10 wrecker programs."

Under the agreement, a Navistar and Tatra branded truck will be marketed under Navistar Defense in all North American markets including the United States military and Foreign Military Sales financed by the United States government. Tatra will also source parts and components through Navistar's global parts and support network for Tatra trucks delivered in markets outside of North America.

"We are tremendously excited about this strategic alliance with Navistar Defense," said Ronald Adams, board of directors' chairman and CEO, Tatra. "Navistar is a great company with a proven track record of success and a very fine team of professionals covering all disciplines of the truck business."

Tatra and Navistar Defense have also agreed to market and sell new Navistar-Tatra trucks in their respective existing markets around the world. Navistar will manufacture vehicles developed under the alliance.
