Missile silos are underground facilities designed to store and launch ballistic missiles. They are typically reinforced to withstand attacks and are equipped with advanced security systems. These silos help protect the missiles from enemy strikes and ensure they can be launched quickly if needed. The primary purpose of missile silos is to serve as a deterrent during conflicts, particularly in the context of nuclear warfare. Countries like the United States and Russia maintain these silos as part of their strategic defense systems, ensuring that they can respond to threats while minimizing the risk of accidental launches.
