Submarine-launched ballistic missiles (SLBMs) are a type of missile designed to be launched from submarines. They are capable of delivering nuclear or conventional warheads over long distances, making them a key component of a country's strategic defense system. SLBMs are typically housed in vertical launch tubes within the submarine, allowing for stealthy deployment. These missiles are guided by advanced navigation systems and can travel at high speeds, reaching their targets with precision. SLBMs contribute to a nation's second-strike capability, ensuring that even if a country is attacked, it can still retaliate effectively. This capability is crucial for maintaining deterrence in global security.
