Cannons of the American "Third System" Period
U.S.10-inch Rodman gun, Model 1861
In 1867, the United States Army installed forty 10-inch Rodman cannons in the first and second tier casemates of Fort Point. These cannons were made using the newest technology, the Rodmand Process. In, 1893, soldiers fired a 17-gun salute to honor Vice President Adlai E. Stevenson during his visit to San Francisco. This may have been the last time Fort Point's Rodman cannon were ever fired.
U.S. 10-inch siege & garrison mortar, model 1841
Although it is identical to weapons used in posts around the San Francisco Bay, this particular mortar was not used to defend the harbor. Fort Point mounted several mortars of this style on the barbette(top) tier.
U.S. 32-pounder "James Banded" gun, Model 1829
This cannon is a replica of a pre-Civil War weapon that was mounted on the barbette tiers of seacoast fortifications. It is identical to weapons used in posts of the San Francisco Bay. Fort Point mounted eleven 32-pounder guns of this style on the barbette tier.

This cannon is a reproduction of pre-Civil War weapon which was mounted on the barbette tiers of seacoast fortifications. It is identical to weapons used in posts of the San Francisco Bay.
