CTT, the newest tactical wheeled vehicle program, will begin replacing the U.S. Army’s aging fleet of heavy tactical wheeled vehicles. The U.S. Army has proposed replacing most variants in its heavy tactical wheeled vehicle fleet with a single platform that shares a common powertrain, chassis and cab. The Army selected four companies to each provide several different prototype vehicles to refine specifications as the program moves to vehicle testing in 2024 and initial production by 2027.

“Allison Transmission is committed to leveraging advancements made in the commercial vehicle industry to provide defense customers with fuel efficient, reliable and innovative propulsion solutions,” said Dana Pittard, Vice President, Defense Programs, Allison Transmission. “System and vehicle level integration expertise is a core competency and differentiator for Allison, and we are proud to deliver next generation capabilities in partnership with our defense customers to optimize vehicle performance for the men and women of our nation’s armed forces.”

Allison’s proven propulsion solutions are operating in nearly all the Department of Defense’s medium and heavy-duty tactical trucks. The company continues to invest in fuel efficient technology such as Allison FuelSense® 2.0, an advanced set of software and electronic controls that deliver fuel savings of up to 6% and reduce CO2 emissions in conventional vehicles all while ensuring maximum equipment readiness of the Army’s tactical wheeled vehicle fleet.

In addition, Allison Specialty Series transmissions are equipped with the company’s next generation electronic controls platform, which delivers advanced communications, functional safety, cybersecurity and over-the-air programming that are at the forefront of commercial vehicle industry adoption.
