The M104 155 mm projectile is a chemical artillery shell designed for use by the U.S. Army. It was specifically designed to carry about 11.7 pounds (5.3 kg) of sulfur mustard (H) or (HD) blister agent (distilled mustard). [5] [6] As early as the 1960s, the shell was also filled with white phosphorus to be used for obscuration and signaling. [7]
Officially designated projectile, 155 mm howitzer, M110, the original round was a 26.8-inch (68.1 cm) steel shell with a rotating band near its base and a burster rod down its center. [7] The original shell typically contained 9.7 pounds (4.4 kg) of sulfur mustard (H) or distilled sulfur mustard (HD) , which would fill the hollow space in the ...

A SMArt-155 round is fired from a standard rifled 155mm artillery tube. 2 The round flies on a ballistic arc, with a range of 27.5 kilometres (17.1 mi) [7] 3 Mid-flight a timer fuse ignites a small ejector rocket in the nose, which drags the two submunitions out of the shell casing. 4 Once clear of the shell, the submunitions fall toward the ...
The 155 mm M549/M549A1 HERA is a separate-loading munition with a two-part forged shell body. The forward HE-filled shell body is constructed from high-fragmentation steel (HF1) and is of a low-drag aerodynamic profile. The rocket-motor body makes up the rear of the shell, this constructed from 4340 steel.
XM1113 extended range artillery round, shown here at a range demonstration, uses a rocket-assist motor In 2021, the U.S. Army plans to produce the upgraded M1156E2/A1, compatible with newer XM1128 high explosive and XM1113 rocket-assisted projectiles to achieve 10 m (33 ft) accuracy at 30 and 40 km (19 and 25 mi) respectively when fired from a ...
It carries a larger payload than the aging M549 Extended Range Projectile or ERP, which is the previous boosted round the M1128 is designed to replace. [1] The M1128's range of 30 kilometres (19 mi) far exceeds conventional (non-boosted) artillery rounds such as the M107 projectile which has a 17 kilometres (11 mi) range.
