Confederate-made 12-pounder howitzer is displayed at Chickamauga and Chattanooga National Military Park. The Model 1841 bronze 12-pounder howitzer barrel was 53.0 in (134.6 cm) from the base ring to the muzzle and weighed 785 lb (356 kg). The diameter of the bore (caliber) was 4.62 in (11.73 cm) and the bore length was 43.25 in (109.86 cm).
The M1841 mountain howitzer was a mountain gun used by the United States Army during the mid-nineteenth century, from 1837 to about 1870. It saw service during the Mexican–American War of 1847–1848, the American Indian Wars , and during the American Civil War , 1861–1865 (primarily in the more rugged western theaters ).
Coupled to the 6-pounder field gun in allocations of the pre-war Army, the M1841 12-pounder howitzer was represented by Models of 1835, 1838 and 1841. With a light weight and respectable projectile payload, the 12-pounder was only cycled out of the main field army inventories as production and availability of the 12-pounder "Napoleon" rose, and ...

The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a dimensionless quantity. [2]: 81 For example, the main guns of the Iowa-class battleships can be referred to as 16"/50 caliber. They are 16 inches in diameter and the barrel is 800 inches long (16 × 50 = 800).
Historically, howitzers fired a heavy shell in a high-trajectory from a relatively short barrel and their range was limited but they were slightly more mobile than similar size field guns. Since the end of World War II , howitzers have gained longer barrels and hence increased range to become gun-howitzers .
This is because naval guns can be built much more strongly than land-based self-propelled gun-howitzers, and have much longer barrels in relation to caliber (for example the 4.5 inch Mark 8 naval gun has a barrel length of 55 calibers, while the standard AS-90 self-propelled gun has a barrel length of 39 calibers). This allows naval guns to ...
