Coast artillery refers to military units and weapons designed to defend coastal areas from naval threats. These forces typically use large-caliber guns, missile systems, and other artillery to protect ports, harbors, and coastal installations. The primary goal is to deter or destroy enemy ships before they can launch attacks on land. Historically, coast artillery played a crucial role in coastal defense during conflicts such as World War I and World War II. Many coastal fortifications, like those found in the United States and Europe, were built to house these artillery systems, showcasing the importance of protecting national shores from maritime threats.
