GM Defense has completed production of the first vehicles in support of the Diplomatic Security Service’s Heavy-Duty armored Sport Utility Vehicle (HD SUV) program. DSS is the law enforcement and security arm of the U.S. Department of State.
Milestone Event: Launch of the Suburban Shield
GM marked the milestone event with Assistant Secretary of State for Diplomatic Security Gentry Smith and other key stakeholders at GM Defense’s Concord, North Carolina-based Manufacturing and Customer Innovation Center.
GM Defense’s HD SUV solution, the Suburban Shield, features a new design with a body-on-frame chassis and suspension to support increased vehicle weight and performance requirements. The vehicle includes a high percentage of proven commercial-off-the-shelf parts from General Motors’ global supply chain, including the body, exterior, propulsion, interior, and brakes, for added reliability.
Advanced Design and Manufacturing for Enhanced Security
“Our Suburban Shield significantly enhances the quality, performance, and safety that is essential to the Diplomatic Security Service and provides our nation’s senior diplomats and their supporting teams a vehicle that enables their important mission for diplomacy and national security,” said Steve duMont, GM Defense president.
“I had the opportunity to try out the prototype,” Smith said. “It had good acceleration, handled better in the turns and the heavy-duty anti-lock braking system was far superior to our aftermarket vehicles. You could really feel the stability and performance in the redesigned chassis. The new HD SUV represents a new cost-effective era in the design and building of these badly needed vehicles to help us carry out our mission to ensure the safe and secure conduct of foreign policy in some of our most challenging and dangerous posts.”
GM Defense won the contract to support DSS’ next generation HD SUV last year. The program is intended to support DSS, in addition to more than a dozen other federal agencies.
