The Army’s artillery ammunition program includes 75 mm (used for ceremonies and simulated firing), 105 mm and 155 mm projectiles and their associated fuses and propelling charges.

Semifixed ammunition for short and intermediate ranges, used in 105 mm Howitzers, is characterized by adjusting the number of multiple propelling charges. Semifixed ammunition for long ranges contains a single bag of propellant optimized for obtaining high velocity, and is not adjustable. The primer is an integral part of the cartridge case, and is located in the base. The 105 mm cartridges are issued in a fused or unfused configuration. Both cartridge configurations are packaged
with propellant.

Separate-loading ammunition, used in 155 mm Howitzers, has separately issued projectiles, fuses, propellant charges and primers. After installing the appropriate fuse on the projectile, the fused projectile is loaded into the cannon along with the appropriate amount of propellant charges and a primer.

The artillery ammunition program includes fuses for cargo-carrying projectiles, such as smoke and illumination, and bursting projectiles, such as high explosives. This program also includes bag propellant for the 105 mm semifixed cartridges and a modular artillery charge system for 155 mm Howitzers.


The mission of the Field Artillery is to destroy, defeat or disrupt the enemy with integrated fires to enable maneuver commanders to dominate in unified land operations. Cannon-artillery-delivered munitions are a vital component of this mission.


  • Insensitive munitions (IM) fill is used in the following high explosive rounds, making the inventory safer: 105 mm M1; 105 mm M1130; 155 mm M1122; 155 mm M795
  • Projectiles that utilize shell bodies obtained from 155 mm cluster munitions that have been demilitarized, significantly lowering unit cost: The M1122, 155 mm IM High-Explosive; M1123, 155 mm Infrared Illumination; M1124, 155 mm Visible Light Illumination; M110A3, 155 mm Spotting Smoke
