California is the seventh Navy ship, and first submarine, to be named after the Golden State. It is the eighth Virginia-class nuclear-powered submarine built to excel in anti-submarine warfare; anti-ship warfare; strike warfare; special operations; intelligence, surveillance, and reconnaissance; irregular warfare; and mine warfare missions. California was commissioned Oct. 29, 2011. California’s motto is Silentium Est Aureum (“Silence is Golden”), which pays tribute to both the submarine force’s motto, The Silent Service, and California’s state motto, The Golden State.

Portsmouth Naval Shipyard is the Navy’s center of excellence for fast attack submarine maintenance, modernization, and repair. The on-time or early completion of submarine maintenance availabilities is critical to maintaining warfighter readiness. As a field activity of NAVSEA, PNS is committed to maximizing fleet readiness by safely delivering first-time quality, on time, and on budget.

Virginia-class submarines, a class of nuclear-powered fast attack submarines, are built for a broad spectrum of open ocean and littoral missions to replace the Navy’s Los Angeles-class submarines as they are retired. Virginia-class submarines incorporate dozens of new technologies and innovations that increase firepower, maneuverability and stealth and significantly enhance their warfighting capabilities. These submarines are capable of supporting multiple mission areas and can operate at submerged speeds of more than 25 knots for months at a time.

Virginia-class submarines displace 7,800 tons, with a hull length of 377 feet and a diameter of 34 feet. With VPM, the submarines will displace 10,200 tons and have a length of 460 feet.

The submarines are capable of speeds in excess of 25 knots and can dive to a depth greater than 800 feet while carrying Mark 48 advanced capability torpedoes, Tomahawk land-attack missiles (TLAMs), and unmanned underwater vehicles (UUV).
