Table of guns by caliber and carriage types
The following is summarized from American Seacoast Defenses, edited by Mark Berhow, with pages referenced from the rows. The units column reflects the lower of the original emplacements or the carriages built, since some emplacements were not armed and some carriages not used. Carriage models after 1905 are not included in the Endicott Era table.
