On June 4, the US Navy laid the keel for USS District of Columbia, the first of its new Columbia-class nuclear-powered ballistic-missile submarines, at an Electric Boat facility in Quonset Point, Rhode Island, Business Insider reports.
The high-profile event was attended by both Adm. Daryl Caudle, commander of US Fleet Forces Command, and Secretary of the Navy Carlos Del Toro, who said the Columbia class “will be the cornerstone of our strategic deterrence” and “the ultimate guarantor of our national security.”
