According to information published by the US DoD on March 14, 2023, Naval Facilities Engineering Systems Command (NAVFAC) Pacific awarded a $2.8-billion task order under a previously-awarded indefinite-delivery/indefinite-quantity multiple-award construction contract to Dragados/Hawaiian Dredging/Orion JV, based in Honolulu, Hawaii, to replace Dry Dock 3 at Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNSY & IMF).

The planned five-year project will construct a graving dock, to be designated Dry Dock 5, in order to support PHNSY’s ability to continue serving the Navy decades into the future by maintaining and modernizing the U.S. Pacific Fleet’s nuclear-powered submarines.
Dry Dock 3 at PHNSY & IMF will become functionally obsolete once the Navy’s Los Angeles-class submarines are no longer in service. The dry dock, built in 1942, cannot service Virginia-class submarines or larger surface ships.
The Navy established SIOP to increase throughput at the four public shipyards by updating their physical layout, upgrading and modernizing their dry docks, and replacing antiquated capital equipment with modern tools and technologies.
Pearl Harbor Naval Shipyard
This shipyard is located in Pearl Harbor, Hawaii and occupies an area of 148 acres. It is one of only four public shipyards operated by the United States Navy and has played a vital role in maintaining and repairing the Navy's fleet for many years.
The shipyard now operates four dry docks that are primarily utilized for repairing and maintaining nuclear submarines, and it employs approximately 5,800 civilian employees and 500 military personnel.
