The Rodman Gun is a type of large-caliber artillery piece developed in the mid-19th century by American engineer Thomas Rodman. It was designed for coastal defense and featured a unique method of casting that allowed for a thicker barrel, which improved durability and firing range. The gun was capable of firing heavy projectiles, including explosive shells, making it effective against naval targets. Rodman Guns were primarily used by the United States military during the Civil War and into the late 19th century. They were often mounted on fortifications and coastal batteries, providing a formidable defense against enemy ships. Despite their impressive design, advancements in artillery technology eventually rendered them obsolete.
