Scale: 1/96    (1/8 inch = 1 foot)

Set includes 22 carronades with carriages, enough to complete one model of USS United States.

Recommended to help build the frigate USS United States (1797) from:

  • Bluejacket Shipcrafters 1/96 scale USS Constitution "Old Ironsides" 
  • Heller 1/96 scale USS Constitution
  • Revell 1/96 scale USS Constitution "Old Ironsides" 
  • Revell 1/96 scale USS United States "Old Waggon" 
  • and more!


These models represent the 42-pounder carronades fit to the frigate USS United States, sistership of USS Constitution, "Old Ironsides".  USS United States, nicknamed "Old Wagon", carried 22 of these weapons.  These models are intended as accurately sized and highly detailed replacements for the Revell 1/96 scale USS United States kit's incorrect 32-pounder carronades.

These 3D-printed models accurately capture the features and dimensions of carronades manufactered by the Columbia Iron Works of Georgetown, Maryland including its unusual stepped bore (the bore had a smaller chamber at the rear allowing for a smaller charge to be used). 


These models' overall scaled dimensions match those recorded in "The American Sailing Navy: The Ships and Their Development", by noted naval historian Howard I. Chapelle, pg. 516.  Some adjustment to the gun openings of your Revell kit may be necessary for best fit. 


Overall dimensions of one carronade and skead (carriage):

  • Length: 29.75 mm
  • Height: 13.16 mm (including gunsight)
  • Width: 7.61 mm (including skead external bolts)

These models are not 3D-printed copies of any plastic, metal, resin or wood kit's parts and therefore may be differently sized than your kit's parts. Some adjustment to you kit's parts may be necessary for best fit.

Carronades were first developed in Scotland at the Carron Iron Works from which they get their name.  They were sometimes referred to as "smashers".  Carronades were designed to be a very powerful, short-range, anti-ship and anti-personnel weapon requiring a smaller crew to operate than a cannon. 

Although there were minor variations among real carronades, these models' scaled dimensions and details match Columbia Iron Works factory drawings.  The most noticeable difference between Columbia-made guns and Carron-pattern guns is that the Columbia-pattern gun has a hemispherical cascabel (breech).
