A "Bunker Buster" is a type of bomb designed to penetrate hardened structures, such as military bunkers or underground facilities. These bombs typically have a robust casing and a high-explosive payload, allowing them to break through thick concrete and steel before detonating. They are often used in military operations to target fortified enemy positions. Bunker Busters can be delivered by various aircraft, including F-15 and B-2 bombers. One well-known example is the GBU-28, which was developed during the Gulf War. These weapons are part of modern warfare strategies aimed at neutralizing threats that are otherwise difficult to reach.
