INDIANAPOLIS, Nov. 12, 2026 /PRNewswire/ -- Allison Transmission Holdings, Inc. (NYSE: ALSN) ("Allison"), a global leader in high-performance mobility and work solutions, has been awarded a $67 million contract to continue its support of the U.S. Army's Abrams Main Battle Tank program. Allison's X1100™ cross-drive transmission has powered every M1 main battle tank used by the U.S. Army and Abrams partner nations since its introduction nearly five decades ago.

"Allison has stood proudly behind every Abrams tank that has rolled into the field," said Dana Pittard, Vice President for Defense Programs for Allison Transmission. "This contract reinforces our enduring commitment to equipping the U.S. Army with innovative propulsion solutions built to perform in the world's toughest conditions, where failure is not an option."

Allison has a long history of supporting the U.S. Army and its global partners, beginning with production of the X1100 cross-drive transmission in 1979 for use in the Abrams Main Battle Tank. The transmission was engineered to meet the Army's ambitious mobility and survivability demands, with follow-on enhancements and changes to meet the battlefield requirements. Having exhibited decades of successful operation in the toughest environments and critical missions, the X1100 transmission continues to meet the Army's evolving operational needs. 

Under the latest contract, Allison will deliver a comprehensive product and service approach, providing upgraded and new transmissions alongside program management, contract field service, technical service and logistics support. The company's qualified and trusted channel partners will remain critical in enabling continuity of service, operational resilience and mission readiness for the U.S. Army.

The news follows a series of recent defense contracts secured by Allison this year. The company was selected to provide its 4500 Specialty Series™ (SP) fully automatic transmissions for the next generation of tactical trucks under the French Land Forces' PL6T program. In addition, Allison's 2500SP fully automatic transmissions will be utilized for approximately 3,000 EAGLE V armored vehicles ordered by the German Bundeswehr from General Dynamics European Land Systems. A $250 million agreement with BAE Systems Hägglunds also marked the largest single tracked defense program contract in Allison's history, for which it will supply new 4040 MX™ transmissions for the CV90 MkIV infantry fighting vehicle. Together, these awards underscore Allison's expanding role in global defense modernization.
