These weapons have played a crucial role in global geopolitics for decades, shaping international relations and serving as a powerful deterrent. This article explores the capabilities, limitations, and implications of ICBMs.

ICBMs vs. Normal Ballistic Missiles

ICBMs are distinguished from other ballistic missiles by their range and payload capacity. Here’s a comparison:

  • Range: ICBMs have a minimum range of 5,500 kilometers (3,400 miles), allowing them to strike targets anywhere on Earth. Normal ballistic missiles have shorter ranges, typically measured in hundreds or thousands of kilometers.
  • Speed: ICBMs travel at hypersonic speeds, making them extremely difficult to intercept. Normal ballistic missiles are also fast but generally not as fast as ICBMs.
  • Payload: ICBMs can carry multiple independently targetable reentry vehicles (MIRVs), each capable of delivering a nuclear warhead to a different target. Normal ballistic missiles usually carry a single warhead.
  • Scale of Destruction: The destructive power of an ICBM depends on the size and type of warhead it carries. Nuclear warheads carried by ICBMs can cause widespread devastation, including firestorms, radiation sickness, and long-lasting environmental damage. Normal ballistic missiles, while still dangerous, typically have less destructive power.

Can ICBMs be Intercepted?

Interception of ICBMs is a complex and challenging task. Missile defense systems, such as those deployed by the United States, are designed to detect and destroy incoming missiles in their boost, midcourse, or terminal phases of flight. However, the high speed and maneuverability of ICBMs make interception difficult, especially in the terminal phase when the warhead is re-entering the atmosphere.
