Strategic Ballistic Missiles (SBMs) are long-range weapons designed to deliver nuclear or conventional warheads to targets far away. They are launched from land-based silos, submarines, or mobile platforms, and follow a ballistic trajectory, meaning they are powered during the initial phase of flight and then coast through space before descending to their target. SBMs are a key component of a nation's nuclear deterrent strategy, providing the ability to strike adversaries quickly and effectively. Countries like the United States, Russia, and China maintain these systems to ensure national security and to deter potential threats from other nations.
