Intercontinental Ballistic Missiles (ICBMs) are long-range missiles designed to deliver nuclear warheads over distances greater than 5,500 kilometers. They are launched from land-based silos 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 toward their target. ICBMs typically have multiple stages, allowing them to reach high altitudes and speeds. They are a key component of the nuclear deterrent strategies of countries like the United States and Russia, ensuring that any potential aggressor understands the consequences of a nuclear attack.
