Columbia-class submarines

Columbia-class submarines are advanced, nuclear-powered ballistic missile subs designed to serve as the U.S. Navy's strategic nuclear deterrent. They are built to quietly patrol oceans for long periods, armed with submarine-launched ballistic missiles capable of delivering nuclear warheads. Their primary purpose is to provide a secure, second-strike capability that deters potential adversaries from attacking, ensuring national security. These submarines feature cutting-edge technology for stealth, endurance, and safety, replacing older Ohio-class submarines to maintain the United States’ assured nuclear deterrence posture well into the future.
