US Navy’s $4.47B Pearl Harbor Submarine Dry Dock Takes Shape as Norfolk Opens $134M Refueling Complex

The US Navy is advancing submarine-maintenance infrastructure at Pearl Harbor and Norfolk, including a $4.47 billion dry-dock project in Hawaii and Norfolk's completed $134 million refuelling complex. Pearl Harbor's new dock is intended to accommodate Virginia-class submarines that cannot be supported by the existing Dry Dock 3, with completion expected in March 2029. Norfolk marked completion of its Dry Dock 4 complex on October 29, adding reactor-servicing workspaces, radiological storage and training capacity. Both projects fall under the Shipyard Infrastructure Optimization Program, supporting nuclear-submarine maintenance, defuelling and inactivation work across the public shipyards.
