Montville, N.J.-based aerospace and defense supplier Marotta Controls announced it has been awarded a multi-million-dollar contract by General Dynamics Electric Boat to design, manufacture, and test Air Reducing Manifolds and flow control valves for the Virginia-class nuclear submarine program, with a contract period of approximately three years. The scope includes integrated design and advanced manufacturing, explicitly incorporating additive manufacturing (AM) to support system performance, reliability, and schedule requirements. Bryan Begane, Vice President of Navy Systems, stated that the award reflects Electric Boat's confidence in Marotta's ability to solve core engineering challenges for Virginia-class submarines. Marotta has supported every U.S. submarine class since the Nautilus and has accumulated complex manifold manufacturing experience on prior Virginia-class and Columbia-class programs. The company has an established track record in additive manufacturing: it has validated metal 3D-printed designs for manifold valve bodies with complex radial channels and deployed the first additive-manufactured valve component on a U.S. Navy destroyer, cutting lead time by 70% (announced July 2025). Value to powder buyers: (1) Submarine manifolds and valve bodies are typical applications for metal additive manufacturing using nickel-based alloys, stainless steel, and copper-nickel alloys, and will continue to drive demand for corresponding powders and wire over the three-year contract; (2) Serial production of additive parts for naval platforms indicates that military-certified metal additive components have entered routine procurement, benefiting powder suppliers with certification capabilities; (3) Watch the procurement pace as the U.S. Navy expands additive components to more ship classes.
