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), design (CAD), 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). 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).12 × VLS tubes (for BGM-109 Tomahawk missiles).Only limited by food and maintenance requirements. With the modified spy sub, the VPM space could account for the extra space needed for the multi-mission platform.$2.8 billion per unit (2019) $3.45 billion per unit w/VPM (2021) Newer generation Virginia-class subs are equipped with Virginia Payload Modules, or VPM, to carry Tomahawk cruise missiles, extending the sub's body by 84 feet. Because the MMP connects the fore and aft sections of the submarine, a tapered passageway called a "wasp waist" passes through the MMP, allowing crew and boat-length wiring to connect both ends of the craft. The multi-mission platform, or MMP, is a fortified section of the hull that can turn the submarine into a hangar of sorts for a host of deep-sea exploratory instruments. Like the submarine under construction, the Jimmy Carter sports a 100-foot hull extension called a multi-mission platform. ![]() ![]() While specific details of the hull design are closely guarded for national security, the new submarine is expected to bolster – and could eventually succeed – the USS Jimmy Carter, a Seawolf-class submarine commissioned in 2005 and presently the only special-mission sub of its kind deployed by the Navy. ![]()
