A ballistic missile is a rocket-propelled weapon that briefly fires its engines and then allows the forces of gravity to carry its cargo to its intended target. Such a weapon has a ballistic trajectory over most of its flight path and categorized according to their range, maximum distance measured along the surface of the earth's geometric surface from the point of launch of a ballistic missile to the point of impact to the intended destination. intercontinental ballistic missiles are missiles that are used on land and in water (usually found on submarines). the range of an intercontinental ballistic missile (ICBM) is over 5,500 km (3,400 miles). Ballistic missiles have been the preferred weapon because they are long range missiles and are of strategic intimidation for rouge regimes seeking to exert political and strategic leverage far in excess of what they would otherwise be able to bear using their conventional military assets.
Ballistic missiles are seen in many regimes, which do not otherwise possess the ability to project military power much beyond their own borders as weapons capable of creating fear and terror in opponents even if these opponents are economically and militarily stronger. Ballistic missiles have a number of distinct characteristics that make them a particularly attractive weapon for developing nations. Compared to other delivery systems, ballistic missiles are many times faster than a manned aircraft, have much shorter flight time to the target and are thus, more likely to penetrate an enemies defenses. Therefore, ballistic missiles can attack without warning, making them ideal for surprise and pre-emptive strikes.
