Since the early 21st century, most NATO armies have settled on 155 mm (6.1 in) weapons as having a good compromise between range and destructive power whilst having a single calibre, which simplifies logistics; however some military forces have retained 105 mm (4.1 in) towed howitzers for their lighter weight and greater portability, including their rapid airlift and airdrop capabilities.
This graph shows different pressure curves for powders with different burn rates. The leftmost graph is the same as the large graph above. The middle graph shows a powder with a 25% faster burn rate, and the rightmost graph shows a powder with a 20% slower burn rate. Energy is the ability to do work on an object. Work is force applied over a ...
The surface of the projectile also must be considered: a smooth projectile will face less air resistance than a rough-surfaced one, and irregularities on the surface of a projectile may change its trajectory if they create more drag on one side of the projectile than on the other. However, certain irregularities such as dimples on a golf ball ...

The Type 91 10 cm howitzer was a standard 105 mm artillery piece of extremely light construction relative to range and weight of projector. [9] It can be identified by its demountable spade plates, long cradle extending almost to muzzle end of tube, a hydro-pneumatic recoil mechanism, Split trail, and interrupted screw breech mechanism. It was ...
American soldiers with 155 mm artillery shells, 10 March 1945. Gun calibers have standardized around a few common sizes, especially in the larger range, mainly due to the uniformity required for efficient military logistics. Shells of 105 and 155 mm for artillery with 105 and 120 mm for tank guns are common in NATO allied countries. Shells of ...
The M119 howitzer is a lightweight 105 mm howitzer, used by the United States Army.It is the American licensed version of the British L119 light gun.The M119 is typically towed by the M1097 or M1152 High Mobility Multi-Purpose Wheeled Vehicle (HMMWV), and can be easily airlifted by helicopter, or airdropped by parachute.
After World War I, the U.S. Army Ordnance Department studied various captured German 105 mm-caliber howitzers and developed the 105 mm Howitzer M1920 by using the Carriage M1920. A box trail carriage design (the M1925E carriage) and two other split trail designs (the T1 and T2) were also developed, but the original split trail design was found ...
