BURNS HARBOR, Ind. (AP) — The 337-foot USS Illinois submarine has been built with steel made at the Arcelor Mittal USA factory in northwest Indiana.
Construction on the $2.7 billion Virginia-class submarine began in March 2011. First lady Michelle Obama christened the vessel at a Connecticut shipyard in October, and it was commissioned in December.
The (Munster) Times reports that the nuclear-powered attack submarine features ArcelorMittal plates throughout the hull, including the nuclear reactor. But it isn’t the only Navy vessel that the steelmaker has provided materials to build.
ArcelorMittal USA plate sales manager Matt Habenicht says the company has supplied steel plate to virtually every submarine in the Navy’s existing fleet.
Plate made at the Porter County facility also goes into Littoral Combat Ships and DDG Destroyers.
