Timken Gears & Services Inc., based in King of Prussia, Pennsylvania, has secured a contract modification worth $119m.

The contracting activity for this endeavour is the Naval Sea Systems Command, based in Washington, D.C..

The company will exercise options to provide three main reduction gear (MRG) shipsets supporting the DDG-51 class. MRGs are large drive systems that transfer torque from a ship's gas turbines to its propeller shafts, enabling the vessel to move at various speeds under changing conditions.

This component is integral to the operation of the DDG-51 class vessels, ensuring their performance and reliability, and the project is expected to be completed by November 2027 and will involve work across multiple locations nationwide.

Huntington Ingalls Industries are the primary constructor of the USS Arleigh Burke DDG-51 class ship. According to GlobalData's "US Defence Market 2022-2027" report, the Arleigh Burke programme has an estimated contract allocation of $33.8bn (2022–32). So far, 51 ships of this class have been delivered, with 12 currently under construction and a further 19 on order.

General Dynamics Bath Iron Works (BIW) recently awarded Timken a long-term contract to deliver MRGs for all future Flight III ships of the Arleigh Burke (DDG-51) class.

The project will involve collaborative efforts across multiple locations. The majority of the work, approximately 77%, will be performed in Santa Fe Springs, California.

At the time of award, $119.2m will be obligated, ensuring the project's financial viability. The funds are expected to remain available until the completion of the current fiscal year, allowing for seamless execution of the contract.
