Sparrows Point, a stretch of waterfront just south of Baltimore, is about to become a shipyard again. On October 6, President Trump stood there and announced that defense company Anduril will spend $3.7 billion of its own money to build submarine parts on the site, USNI News reported.
For more than a century, Bethlehem Steel ran a giant steel mill and shipyard here. The mill shut down in 2012, and the land has since been filled with warehouses. Now the plan is a 2-million-square-foot yard with 3,100 workers, ready by 2030.
Here is the surprising part. Anduril is not going to build submarines. Its first product is the torpedo tube, the pipe a submarine fires its weapons through. That sounds small, but it is one of the parts holding up the whole line. America’s main attack submarine, the Virginia class, is put together at only two shipyards, General Dynamics Electric Boat and HII’s Newport News. The Navy wants two new boats a year and has struggled to get close. When one part arrives late, the whole boat waits. A Trump administration official called the tubes a “gating component,” meaning nothing moves until they show up. Anduril says it will move on to bigger modules and, one day, whole hull sections. The new yard adds about 15% more working hours to the Virginia-class program.
Now follow the money, because the order matters. Anduril builds first with its own $3.7 billion. The Navy has signed a contract worth up to $2.9 billion, but it pays only as finished parts actually arrive. Add the two together and you get the $6.6 billion figure in most headlines. If Anduril is slow, Anduril eats the cost. That is unusual in defense, where the government usually pays up front and takes the risk.
One line from the event is not in any document. Trump told the crowd that taxpayers would get a 40% stake in the new yard. Anduril’s own announcement says nothing about government ownership. Until someone puts it on paper, treat it as a speech line, not a deal term.
Korea is watching Sparrows Point closely, because it wants the same work. Hanwha bought Philly Shipyard in Philadelphia for about $100 million in 2024 and plans to invest $5 billion to grow it, part of Korea’s $150 billion shipbuilding pledge to the US. Hanwha has said the yard could build nuclear submarines one day. Korea’s own defense minister was less sure. In November 2025, he said the Philadelphia yard still lacked the technology, people and facilities, and that Korea’s own nuclear submarine should be built at home. For now, a foreign-owned yard usually starts as a supplier, not the lead builder. Anduril just got that supplier seat with a presidential ceremony.
The steel mill is gone. The dock is still there, and the Navy has finally found a reason to use it.
My take: Not a ship. A tube.
Not advice. Just how I see it.
