A missile silo is a fortified underground structure designed to house and launch ballistic missiles. These silos are typically built to withstand nuclear blasts and other forms of attack, ensuring the missiles remain operational during a conflict. They are equipped with heavy doors and advanced security systems to protect the missiles from unauthorized access. Missile silos are often associated with military installations and are part of a country's strategic defense system. Countries like the United States and Russia have developed extensive networks of silos to maintain their nuclear deterrent capabilities. The silos are usually located in remote areas to minimize the risk of detection and attack.
