Italy's Leonardo DRS has opened a 140,000‑square‑foot naval power and propulsion facility in Charleston, South Carolina, expanding U.S. production capacity for Navy shipbuilding and the Columbia‑class submarine program. The site supports advanced manufacturing, assembly, and testing of electric and steam‑turbine systems. Executives call it a national‑level investment that strengthens the defense industrial base and enables scalable power architectures for next‑generation naval platforms.
