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. SLBMs are typically housed in vertical launch tubes within submarines, allowing for stealthy deployment. These missiles are part of a broader category of weapons known as ballistic missiles, which follow a ballistic trajectory to reach their targets. Countries like the United States and Russia maintain fleets of submarines equipped with SLBMs to ensure a second-strike capability in the event of a nuclear conflict.
