Hadrian opened its 2.25-million-square-foot Alabama factory as the Navy faces 70 million submarine-production hours and a severe workforce gap.
At the opening of Hadrian’s Factory Four in Cherokee, Alabama, CEO Chris Power and Vice Admiral Robert Gaucher discussed rebuilding U.S. submarine manufacturing. Gaucher said submarine work has grown from about 13 million hours for one Virginia-class boat to roughly 70 million hours for the Navy’s current fleet needs—more than five times the workload of a decade ago. The 2.25-million-square-foot facility will support Columbia- and Virginia-class programs. Power argued that spending alone cannot solve shortages of welders, machinists and inspectors; software, training and flexible production must raise productivity. Gaucher identified obsolete maintenance parts and sequence-critical components as early opportunities, while noting some workers are below 50% productive. The speakers also described submarines’ stealth, nuclear deterrence and potential role coordinating underwater drones. Power said the factory will require about 600 people to establish, and stressed that precision, quality and workforce development—not simply automation—are essential to making the model repeatable.
