Allison Transmission has secured a contract to provide transmission upgrades and technical support for Abrams main battle tanks (MBTs) in service with the US Army.

The estimated value of this contract is approximately $51m. The award also covers support and upgrades for the US’ foreign military sale customers.

The company is expected to begin the delivery of X1100-3B1 transmission and related technical support for the Abrams tanks from January next year. Work will continue until March 2024.

According to a US Department of Defense (DoD) contract announcement, the cost-plus-fixed-fee and firm-fixed-price contract is being managed by the US Army Contracting Command, Detroit Arsenal, Michigan.

The DoD stated that all the associated work will be carried out by the company in Indianapolis, Indiana.

Allison Transmission Defence Programme vice-president Dana Pittard said: “The Abrams is the most prevalent main battle tank in the free world, and the recent announcement of defence sales expanding to Taiwan, Australia, and Poland increases its presence to eight US partner nations.”

Introduced in the early 1980s, the Abrams tank is currently in service with the US Army and eight allied and partner nations.

Allison has been continuously engaged in providing innovative advancements to fulfil the customers’ requirements, simultaneously ensuring enhanced transmission and performance.

In July this year, Allison secured a US Army contract to support the modernisation programme of its M88A3 Heavy Equipment Recovery Combat Utility Lift and Evacuation System (HERCULES) prototype vehicle.

Pittard added: “Our internal investments have led to growth in the defence end market, with new contracts in the last six months for Abrams, the US Army’s newest light tank, mobile protected firepower, M88A3 HERCULES, and India’s future infantry combat vehicle.”
