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.
