Penetrator bombs are specialized munitions designed to penetrate hardened targets, such as bunkers or underground facilities. They typically feature a robust, streamlined shape and are made from dense materials like steel or tungsten, allowing them to withstand the impact and reach their target effectively. These bombs often contain a high-explosive charge that detonates after penetration, maximizing damage to the target. They are commonly used by military forces, including the United States Air Force, to neutralize fortified positions during conflicts.
