“On time and under budget” may take on new meaning when AI is brought into the hard manufacturing sector…

Advanced robotics and automation are helping bring a $2.4 billion submarine component manufacturing center to life in the heart of Alabama.
Hadrian just opened Factory 4 in Cherokee, Alabama, a 2.2 million-square-foot advanced manufacturing facility dedicated to producing components for Columbia- and Virginia-class submarines.
Facts:
🔹 $2.4B public-private partnership ($1.5B private / $900M Navy appropriations)
🔹 2.2M sq. ft. facility at Barton Riverfront Industrial Park, repurposed from a former FreightCar America railcar plant that closed in 2021 after production moved to Mexico
🔹 First large-scale inland facility dedicated exclusively to the U.S. maritime industrial base
🔹 Produces sequence-critical and commodity components, including parts, assemblies, and finished products, for Columbia- and Virginia-class submarines
🔹 Runs on Hadrian’s Opus AI platform: ~80% automated, 1:5 to 1:6 human-to-machine ratio, CNC and robotics cells, 30-day workforce training
🔹 Up to 1,000 jobs, with full-rate production targeted within 24 months
🔹 First of three planned Hadrian maritime facilities; the second will be a “Foundry of the Future” for castings and forgings
🔹 Part of the Golden Fleet initiative ($59B cumulative shipbuilding investment)
🔹 Hadrian is a four-year-old startup, Series C backed by Founders Fund and Lux Capital, valued at $1.6B
The Navy calls this “distributed shipbuilding.”
Instead of concentrating schedule-critical component production at shipyards in Connecticut, Rhode Island, and Virginia, the plan is to move that work inland to dedicated manufacturing facilities. Shipyards can then focus more on module assembly, helping reduce one of the biggest bottlenecks in submarine construction.
This only works because Hadrian has invested heavily in advanced manufacturing and Physical AI. The facility runs on Hadrian’s Opus platform, which integrates CNC machining, robotics cells, and automated inspection into a single production flow. The target is roughly 80% automation with a 1:5 human-to-machine ratio.
Hadrian says that makes the system five to ten times more productive than legacy defense manufacturing, while also allowing workers with no prior manufacturing experience to be trained to full productivity in 30 days.
This is what reindustrialization looks like when advanced manufacturing, Physical AI, and national security align.
