A ballistic missile is a type of missile that follows a ballistic trajectory to deliver a payload to a predetermined target. These missiles are powered during the initial phase of flight and then follow a free-fall path, making them capable of reaching high altitudes and long distances. They are often equipped with nuclear, chemical, or conventional warheads, which can cause significant destruction upon impact. Ballistic missiles are categorized based on their range, including short-range, medium-range, and intercontinental ballistic missiles (ICBMs). Countries like United States and Russia have developed advanced ballistic missile systems, which play a crucial role in modern military strategy and deterrence.
