The dock does not support other vessels, such as the existing Virginia-class submarines or larger surface ships. “This project is a key investment in increasing capacity and modernizing our nation’s public shipyards through upgraded dry docks and facilities, new equipment, and improved workflow.” ‘Historic Effort’īuilt in 1942, PHNSY & IMF Dry Dock 3 will become obsolete once the service’s Los Angeles-class submarines are decommissioned. “As part of the Navy’s Shipyard Infrastructure Optimization Program, replacing Dry Dock 3 at Pearl Harbor Naval Shipyard is a critical enabler of increased naval capability,” US Navy Industrial Infrastructure Program Executive Officer Pete Lynch stated. The program will revamp four public shipyards to serve current and future classes of submarines and carriers. Work for the contract will be conducted as part of the Shipyard Infrastructure Optimization Program to bolster shipyard infrastructure dedicated to nuclear-powered warships.

Shipyard Infrastructure Optimization Program The five-year agreement will see the development of a new graving dock (Dry Dock 5) to replace Dry Dock 3, sustaining PHNSY & IMF capabilities that modernize and maintain the US Pacific Fleet’s nuclear-powered submarines. The US Navy has awarded a joint venture of Dragados, Hawaiian Dredging, and Orion a $2.8-billion contract to construct a concrete dry dock at Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility ( PHNSY & IMF) in Oahu, Hawaii.
