shipyards capable of building nuclear-powered submarines. The Virginia class is built through an industrial arrangement designed to maintain both GD Electric Boat and Newport News Shipbuilding, the only two U.S. The vehicle was designed as an affordable test platform for new technologies. In 2001, Newport News Shipbuilding and the General Dynamics Electric Boat Company built a quarter-scale version of a Virginia-class submarine dubbed Large Scale Vehicle II (LSV II) Cutthroat. In a 10 March 2005 statement to the House Armed Services Committee, Ronald O'Rourke of the CRS testified that, assuming that the production rate remains as planned, "production economies of scale for submarines would continue to remain limited or poor." In hearings before both House of Representatives and Senate committees, the Congressional Research Service (CRS) and expert witnesses testified that the annual procurement rate of only one Virginia-class boat-rising to two in 2012-would result in excessive unit production costs, yet an insufficient complement of attack submarines. Improvements in shipbuilding technology have trimmed production costs below the $1.8 billion projected fiscal year 2009 dollars. To reduce costs, the Virginia-class submarines use many " commercial off-the-shelf" (COTS) components, especially in their computers and data networks. The Virginia class was intended in part as a less expensive alternative to the Seawolf-class submarine ($1.8 billion vs $2.8 billion), whose production run was canceled after just three boats had been completed. Each submarine is projected to make 14–15 deployments during its 33-year service life. Constructing a single Virginia-class submarine has required around nine million labor hours, and over 4,000 suppliers. īy 2007 approximately 35 million labor hours had been spent to design the Virginia class. Design problems for Electric Boat-and maintenance problems for the Navy-ensued nonetheless. The Virginia-class submarine was the first US Navy warship with its development coordinated using such 3D visualization technology as CATIA, which comprises computer-aided engineering (CAE), computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management (PLM). The "Centurion Study" was initiated in February 1991. The class was developed under the codename Centurion, later renamed New SSN (NSSN). History Rendering of a Virginia-class attack submarine If the SSN-AUKUS fell behind schedule, Australia would have the option of purchasing two additional Virginia-class submarines.
On 14 March 2023, the trilateral Australian-British-American security pact known as AUKUS announced that the Royal Australian Navy would purchase three Virginia-class submarines as a stopgap measure between the retirement of their conventionally powered Collins-class submarines and the acquisition of the future SSN-AUKUS class submarines. Virginia-class submarines will be acquired through 2043, and are expected to remain in service until at least 2060, with later submarines expected to operate into the 2070s. They are scheduled to replace older Los Angeles-class submarines, many of which have already been decommissioned.
Virginia-class submarines are designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. Designed by General Dynamics Electric Boat (EB) and Huntington Ingalls Industries, the Virginia class incorporates the latest in stealth, intelligence gathering, and weapons systems. The Virginia class, or the SSN-774 class, is the latest class of nuclear-powered cruise missile fast- attack submarines in service with the United States Navy. 4 × 21" torpedo tubes for Mk-48 torpedoes or UGM-84 Harpoon missiles.12 × VLS tubes (1 × Tomahawk BGM-109 each).25 × torpedoes & missiles (torpedo room) + 12 × missiles (in the VLS tubes).4 × 21" torpedo tubes (for Mk-48 torpedos or UGM-84 Harpoon missiles).
