Ballistic missile systems are weapons designed to deliver a payload over long distances through a high-arcing trajectory. They are launched from various platforms, including silos, mobile launchers, and submarines. Once in flight, these missiles follow a ballistic path, meaning they are primarily powered during the initial launch phase and then coast through space before descending toward their target. These systems can carry conventional explosives or nuclear warheads, making them significant in military strategy. Countries often develop their own ballistic missile systems to enhance national security and deterrence capabilities. Examples include the Minuteman III in the United States and the DF-41 in China.
