More than 10,000 shipbuilders from NNS and Electric Boat participated in the construction of Massachusetts, alongside thousands of suppliers across the country, including more than 20 in Massachusetts that support Virginia-class submarine construction at NNS.

Nuclear-powered fast attack submarine Massachusetts was christened in May 2023 at NNS by ship’s sponsor Sheryl Sandberg, founder of Lean In, and former chief operating officer of Meta (formerly Facebook).
