This is an 800-acre shipyard. When I first came here after college, I saw the massive equipment and huge ships, and realized how little I actually knew about naval engineering. Ingalls has built nearly 70 percent of the U.S. Navy fleet. We have 11 military vessels under construction, and nearly 12,000 employees. The biggest challenge is seeing how the millions of pieces fit together—that’s my job. To build one of these boats, which can reach more than 800 feet long, we create units. These are the building blocks, like Legos, that we connect and stack together to make bigger sections of the craft. Some units are four decks high, and some are a single level. We lay down the lowest units along the keel in a cradle while we’re putting together sections of piping and electrical components for the water, cooling, and propulsion systems.
