US 13-Inch Mortars were designed for US Army use in seacoast defenses. During the Civil War, they were used by the US Army in siege works - famously including the “Dictator” at Petersburg. They were used by the US Navy aboard mortar schooners and barges. As seen in the table below, the mortar fired a 210+ pound shell using an up to 20-pound propellant charge to reach targets up to 4,500 yards away.
