The X1100 has been used in every M1 Abrams main battle tank operated by the US Army and its partner nations since production began in 1979, according to Allison.
The company said its support will include assistance from its qualified channel partners to maintain service continuity and support US Army operations. It did not disclose how many transmissions will be delivered under the contract.
Allison Transmission defence programme vice president Dana Pittard said: “This contract reinforces our enduring commitment to equipping the US Army with innovative propulsion solutions built to perform in the world’s toughest conditions, where failure is not an option.”
The X1100 is a cross-drive transmission that combines the transmission and steering functions required to drive and manoeuvre a tracked vehicle.
Allison said the system has undergone upgrades and modifications over several decades to meet changing Army requirements.
The company was also selected to provide its 4500 Specialty Series fully automatic transmissions for the French Land Forces’ PL6T tactical truck programme and 2500SP transmissions for approximately 3,000 EAGLE V armoured vehicles ordered by Germany’s Bundeswehr from General Dynamics European Land Systems.
Recently, Allison signed a $250m agreement with BAE Systems Hägglunds to supply 4040 MX transmissions for the CV90 MkIV, described as its largest single tracked defence programme contract to date.
