Virginia-class submarine
The Virginia-class, also known as the SSN-774 class, is a class of nuclear-powered fast attack submarines (hull classification symbol SSN) in service with the United States Navy. The Virginia-class attack submarine is the U.S. Navy’s newest undersea warfare platform and incorporates the latest in stealth, intelligence gathering and weapons systems technology. Attack submarines are designed to seek and destroy enemy submarines and surface ships as well as project power ashore with Tomahawk cruise missiles and Special Operation Forces, carry out Intelligence, Surveillance, and Reconnaissance (ISR) missions; support carrier battle group operations; and engage in naval mine warfare. Virginia-class submarines are designed for a broad spectrum of open-ocean and littoral (shallow coastal water) missions. They are replacing older s, many of which have already been decommissioned. The ''Seawolf''-class attack submarine was originally intended to succeed the Los Angeles-class, but production was canceled after only three submarines were produced due to budgeting restraints at the end of the Cold War, and the final submarine was manufactured in 1995. Virginia-class submarines will be acquired through 2043, and are expected to remain in service past 2060. Based on recent updates to the designs, some of the Virginia-class submarines are expected to still be in service in 2070.
