Hadrian’s Factory Four targets 70 million submarine hours with software, workforce training, and U.S. manufacturing.
At the opening of Hadrian’s 2.25-million-square-foot Factory Four in Cherokee, Alabama, Vice Admiral Robert Gaucher and Hadrian CEO Chris Power outlined the U.S. submarine industrial base’s capacity crisis. Replacing Ohio-class submarines with Columbia-class boats while sustaining Virginia-class production requires roughly 70 million work hours—more than five times the demand little over a decade ago—amid a workforce shortage created after the Cold War. Power argues software-driven factories can make machinists, welders, and inspectors dramatically more productive while supporting high-mix, low-volume production. Gaucher identified obsolete parts, air flasks, hatches, and other sequence-critical materials as early opportunities, noting some shipyard tasks operate below 50% productivity. They also discussed submarines’ stealth, nuclear second-strike role, and future command of underwater drones. A Columbia-class submarine costs about $16 billion and takes nearly a decade, but Hadrian aims to repeat Factory Four’s model nationwide.
