US Wind has relinquished its lease at Tradepoint Atlantic's Sparrows Point site in Baltimore County, Maryland, to Anduril Industries. The change, announced on Tuesday, October 6, ends the company's current plans to fabricate offshore wind turbine towers and monopiles there.
"Our offshore wind plans, like many other similar projects in the US, are delayed due to legal disputes and uncertainty created by federal agencies. So, we are shifting our focus to helping Anduril build a state-of-the-art manufacturing facility at Sparrows Point," said US Wind CEO Jeff Grybowski.
Anduril plans to invest $3.7 billion in Arsenal-2, a 187-acre (76-hectare) facility that will produce large assemblies, along with components, for Virginia-class submarines.
These will be delivered to General Dynamics Electric Boat and Newport News Shipbuilding for final assembly.
The facility will have more than two million square feet of production space and a 1,200-foot (366-metre) graving dock. Initial operations are expected in 2030.
US Wind first leased 90 acres (36 hectares) at Sparrows Point in 2021 for Sparrows Point Steel, a foundation fabrication facility that Haizea Wind Group was later engaged to operate.
The US Department of Transportation withdrew $47.4 million in port infrastructure funding for the project in August 2025. The company said at the time that the project would still proceed.
US Wind's offshore wind project off Ocean City received approval for up to 114 turbines and 2,200 megawatts in December 2024. Ocean City has challenged that approval in court, and the Trump administration has sought to have it reconsidered.
