Building the Shipyards the Nation Needs

The Shipyard Infrastructure Optimization Program’s (SIOP) mission is to execute the Navy’s once-in-a-century investment to reconfigure, modernize and optimize our four aging Naval Shipyards into new modern facilities that will serve this Nation into the future.

In September 2021, the Department of the Navy updated SIOP’s reporting relationships to ensure disciplined and synchronized execution of the multiple major construction efforts managed within SIOP and designated Naval Facilities Engineering Systems Command as the single, responsible executive lead for execution of SIOP and established the Program Executive Office Industrial Infrastructure to oversee the SIOP Program Management Office - PMO 555

  • The Navy’s four public shipyards – Norfolk Naval Shipyard, Portsmouth Naval Shipyard, Puget Sound Naval Shipyard and Intermediate Maintenance Facility, and Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility – are essential elements of our national defense.
  • The Navy's four public shipyards need substantial recapitalization and reconfiguration in order to improve the timely return of ships and submarines back to the fleet following maintenance and modernization.
  • Completing ship and submarine maintenance availabilities on time and returning getting them back to the fleet is vital to ensuring the U.S. maintains its maritime dominance. 
  • The Navy is investing heavily in shipyard infrastructure. SIOP will construct and recapitalize dry docks, recapitalize and reconfigure infrastructure, and modernize industrial plant equipment.
