The USS Illinois (SSN-786) is a Virginia-class nuclear-powered attack submarine operated by the United States Navy. As the third vessel bearing the name Illinois, she continues a distinguished naval legacy, following earlier battleships BB-7 and BB-65 (the latter of which was never completed). Built by the Electric Boat division of General Dynamics, Illinois is a Block III variant, featuring a redesigned bow and advanced technology derived from the Ohio-class SSGNs, enhancing its operational capabilities. Construction of USS Illinois began with the keel-laying ceremony on June 2, 2014, at Electric Boat’s Groton, Connecticut yard, following the contract awarded on December 22, 2008, to Huntington Ingalls Industries in partnership with Electric Boat. The submarine was launched on August 8, 2015, and successfully completed sea trials by August 2, 2016. She was officially delivered to the Navy on August 27, 2016, and commissioned at Naval Submarine Base New London on October 29, 2016. The commissioning ceremony was attended by First Lady Michelle Obama, who served as the ship’s sponsor, symbolizing her support for military families and her close association with the vessel’s crew. Measuring approximately 377 feet in length with a beam of about 34 feet, the USS Illinois is equipped with advanced stealth and combat systems typical of Virginia-class submarines, designed for a broad spectrum of missions including intelligence gathering, anti-submarine warfare, and strike operations. In November 2017, the submarine was reassigned from Naval Submarine Base New London to Naval Base Pearl Harbor, where she now operates as part of Submarine Squadron One. The ship’s crest, designed by Christopher Durdle of Illinois, symbolizes the state’s heritage and the vessel’s significance within the Navy. Overall, USS Illinois exemplifies cutting-edge submarine technology and strategic naval power, contributing to U.S. maritime security and undersea warfare capabilities.
