The development of submarine-launched ballistic missile (SLBM) systems was a critical aspect of the Cold War arms race between the United States and the Soviet Union. These systems, deployed on nuclear-powered submarines (SSBNs), were at the forefront of technological competition between the two superpowers, driving advancements in both military and civilian technologies, including space exploration.
