The Rodman CannonsThe guns in front of you are the heaviest cannons ever mounted at Fort McHenry. The largest fired exploding projectiles weighing 440 pounds. Mass-produced they represent the "coming of age" of America's iron industry. A special process developed by Thomas J. Rodman, enabled them to cool from the inside out giving them durability and their distinctive bottle-shaped appearance.
