Allison to Supply X1100 Transmission to US Army Through 2021

Supporting Sustainment of ABRAMS MBT Fleet

The US Army has selected Allison Transmission to provide the X1100-3B1 propulsion solution for the M1A2 ABRAMS main battle tank (MBT). The contract, valued at approximately $162 million (€147 million), includes transmission production, upgrades, sustainment kits and service support. Deliveries began in March 2020 and will continue through December 2021.

Our support for the Army’s armored formations spans five decades,” said Dana Pittard, Vice President for Defense Programs. “This contract demonstrates that Allison’s long-term relationship with the Army is built on trust, partnership and a mutual commitment to the ABRAMS fleet.”

The X1100 cross-drive transmission, which Allison began producing in 1979, is geared for heavy-tracked combat vehicles weighing 50=70t or more. This contract supports the Army’s efforts to upgrade the ABRAMS tank – which has been the cornerstone of the American armoured brigade – to the M1A2 SEP v3 configuration. Enhancements and upgrades to the battle-tested design will support the Army’s needs for decades to come.

Relevant work will be conducted at the company’s manufacturing centre in Indianapolis. “Our team of hundreds of dedicated men and women from the UAW Local 933 demonstrate a commitment to excellence daily […] Many are veterans or have relatives who serve, and recognize the privilege and responsibility of providing quality products to our nation’s military,” Pittard stated.
