The Los Angeles improved-class attack submarine USS Cheyenne (SSN 773) moves berths following an undocking evolution at Portsmouth Naval Shipyard in Kittery, Maine, Feb. 7, 2025. Cheyenne successfully undocked Feb. 6, and has undergone major repairs, structural inspections, and replacements of mechanical and electrical systems while at the shipyard. This extensive work, led by the project team, has enhanced the submarines capabilities, ensuring advanced systems are delivered to warfighters at the tip of the spear.
