ധധ2 Artillery: America’s Firepower

There are two types of artillery: ɢυиѕ and howitzers. A howitzer combines the power of a ɢυи with the high or low trajectory of a mortar, usually at moderate velocities. An alternate definition is a tube length between twenty and thirty calibers—a four-inch-diameter ωєαρσи with a barrel measuring eighty to 120 inches. Conversely, a ɢυи is a cannon with a barrel of thirty calibers or more, firing a high-velocity round at fairly low angles.

Artillery usually was towed in the Second World ധąɾ but also was self-propelled, especially in armored formations requiring artillery to advance with the tanks.

WW2 Artillery: American

Before World ധąɾ II, American artillery was heavily influenced by foreign designs—especially French. However, as World ധąɾ I equipment aged, more modern equipment appeared in the years preceding American entry into the second ¢σиƒℓι¢т.

U.S. infantry divisions had substantial artillery support—four batteries, each with twelve tubes. Three batteries had 105 mm howitzers and one with 155 mm ɢυиѕ. By D+4 (i.e., the fourth day after D-Day), the U.S. Army had 624 towed or self-propelled artillery pieces ashore.

Airborne forces needed small, portable artillery to offset their firepower disadvantage, and the pack howitzer met the need. Fielded in 1927, the M1A1’s four-man crew could assemble the ωєαρσи from eight parts in a few minutes. Two Waco gliders needed to carry the pack howitzer with a jeep and trailer, while Britain’s larger Horsas could deliver the ɢυи, transport, and crew intact. The assembled piece weighed 1,300 to 1,400 pounds, firing to ranges beyond nine thousand yards.

105 mm


The M2 howitzer was based on a 1920s design that was introduced to service in 1934. Weighing 2.3 tons, it was served by a six-man crew and proved uncommonly versatile. It fired a four-inch, thirty-five-pound shell about nine miles with high єχρℓσѕινє, antitank, white phosphorous, chemical, or illumination rounds. Some 105s were fired from their landing craft while approaching Omaha and Utah beaches on D-Day.

155 mm
Introduced in the summer of 1941, the M1 Howitzer replaced the M1918 six-inch ωєαρσи. The M1A1 and M2 ‘‘Long Toms’’ were far more capable than the previous ωєαρσи, especially in range. The carriage was designed for improved mobility, and, with an eleven-man crew, it provided a much-needed improvement in division artillery. The howitzer weighed 5.4 tons and fired a 108-pound shell almost seven miles. High єχρℓσѕινє, white phosphorous, and chemical rounds were produced.

A self-propelled 155 vehicle, the M12, was delivered to Normandy and proved particularly valuable to armored divisions, which naturally advanced faster than infantry units. The ɢυи was the M1917/1918 on an M-3 Stuart light tank chassis.
