The U.S. Army selected Allison Transmission, the largest global manufacturer of medium- and heavy-duty fully automatic transmissions for commercial and military vehicles, to provide the X1100-3B1 propulsion solution for the M1A2 Abrams Main Battle Tank. The contract, valued at approximately $162M, 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 at Allison Transmission. “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 is geared for heavy-tracked combat vehicles weighing 50 tons to more than 70 tons. Allison began producing the X1100 in 1979. Since then, the Abrams tank has been the cornerstone of American armored brigades. This contract supports the Army’s efforts to upgrade the Abrams tanks to the M1A2 SEP v3 configuration. Enhancements and upgrades to this battle-tested design will support the Army’s needs for decades to come.
