When acceleration ceased shortly after the shell left the gun barrel, the hammer and fuze body were travelling at the same speed and the hammer ceased to "set back", freeing the tape. The shell's rotation then caused a weight on the end of the tape to unwind the tape through centrifugal force, hence activating the fuze. Because of this, usage ...
A mixture of designations were in use for land artillery from the First World War (such as the BL 60-pounder gun, RML 2.5 inch Mountain Gun, 4 inch gun, 4.5 inch howitzer) through to the end of World War II (5.5 inch medium gun, 25-pounder gun-howitzer, 17-pounder tank gun), but the majority of naval guns were by caliber. After the end of World ...
Most engagements using guns in this size range used direct fire at enemy from 1,500 yards (1,400 m) to 3,000 yards (2,700 m) distant, at which ranges the residual shell velocity was correspondingly higher, as in the table – at least in the earlier stages of World War 1. Trajectory and pattern of US 3-inch (76 mm) Shrapnel shell of WWI era.
The 37 mm Infantry Gun Model 1917 was a light artillery piece produced in the United States during World War I for the French Army. It was adopted by the US Army when it entered the war on the side of the Allies .
While the light artillery remained in use, it was supplemented by heavy artillery installed in fixed positions. Because of the need for heavy artillery, many older guns from the 19th century were used. While these guns lacked the capabilities of newer artillery, they could still fire large shells over long distances. [3]
When the United States entered the First World War it had a need for long-range heavy artillery, so guns produced for the US Army were given the designation 6-inch gun M1917. In some US sources the Mark XIX designation was also used. 100 weapons were acquired from the British by the US Army beginning in 1917, along with 50 "gun bodies ...
For the opening barrage at the Battle of Menin Road on 20 September, the ratio of medium/heavy artillery to field artillery reached 1 : 1.5 for the first time, reflecting more heavy guns rather than fewer field guns. 18-pounders were to fire 50%-50% shrapnel and HE with 25% of the HE fuzes set to delay.

Shells for the 42-centimetre guns were generally 1.5 m (4 ft 11 in) long, weighed between 400 and 1,160 kg (880 and 2,560 lb), and were propelled via primer loaded into the gun with a brass casing. Siege artillery shells were produced in limited runs of varying quality.
