This list contains all types of cannon through the ages listed in decreasing caliber size. For the purpose of this list, the development of large-calibre artillery can be divided into three periods, based on the kind of projectiles used, due to their dissimilar characteristics, and being practically incommensurable in terms of their bore size: The list includes only cannons that were actually built, that is, cannons that existed only as concepts, ideas, proposals, plans, drawings or diagrams ("paper cannons" if you will) are excluded. Also excluded are those cannons that were only partially built (not a single complete artillery piece of the cannon type in question built). The list includes cannons that were completed (fully built) but did not fire even once (or there is debate/insufficient evidence about whether the cannons were ever fired). Also cannons that never were used in combat are included. Naturally the list only includes real cannons (made from metal and meant to be fired with gunpowder and a projectile to cause major destruction) and replicas etc. (made from plastic or fiberglass for example) and other non-real cannons (meaning those cannon-like pieces that were not meant to be fired with gunpowder and a projectile capable of causing major destruction) are excluded.

Cannon by caliber

Stone balls

Heyday: 15th to 17th centuries

Iron balls and shot

Heyday: 16th to 19th centuries Twenty-inch (508 mm) Rodman and Dahlgren smoothbore cannons were cast in 1864 during the American Civil War. The Rodmans were used as seacoast defense. Although not used as intended, two 20-inch Dahlgrens were intended to be mounted in the turrets of USS Dictator (1863) and USS Puritan (1864). Both Rodman gun and Dahlgren gun were designed to fire both shot and explosive shell.

Explosive shells

Heyday: 19th to 20th centuries. List contains cannons of 16 inch and greater caliber.
