An Intermediate-Range Ballistic Missile (IRBM) is a type of missile designed to travel distances between 3,000 and 5,500 kilometers. These missiles are typically launched from ground-based platforms and follow a ballistic trajectory, meaning they are powered during the initial phase of flight and then coast through space before descending towards their target. IRBMs can carry conventional or nuclear warheads and are often used for strategic military purposes. They are capable of reaching targets in neighboring countries or regions, making them significant in international defense and security discussions, particularly in relation to treaties like the Intermediate-Range Nuclear Forces Treaty.
