![]() At one point the British Ministry of Defence studied "up-gunning" the Royal Navy's 4.5 inch Mark 8 naval guns to give increased firepower and a common caliber between the Royal Navy and the British Army. Since the end of WWII, 155 mm has not found any use among naval forces despite its ubiquity on land, with most NATO and aligned navies using 76 mm (3 in), 100 mm (3.9 in), 114 mm (4.5 in), or 127 mm (5 in) guns on modern warships. Russian guns and those of former Soviet bloc countries tend to use 122 mm (4.8 in),ġ30 mm (5.1 in) and 152 mm (6.0 in) weapons in similar roles. ![]() ![]() This has led to the obsolescence of larger caliber artillery weapons such as the 175 mm (6.9 in) and 203 mm (8 in), although some militaries retain 105 mm (4.1 in) weapons for their light weight and portability. They are seen as striking a good compromise between range and destructive power, while using only a single caliber simplifies logistics. ![]() Since the early 21st century, most NATO armies have adopted 155 mm weapons as an all-purpose standard. After several meetings, on 16 April 1874 the committee settled on the 15.5 cm caliber (in the subsequent program-letter of the committee, dating from 21 April 1874, the caliber was for the first time expressed as 155 mm). The caliber originated in France after its defeat in the Franco-Prussian War of 1870-1871, when an artillery committee met on 2 February 1874 to discuss new models for the French fortress and siege artillery, among which there was a piece in the 14 to 16 cm caliber range (later became De Bange 155 mm cannon).

It is marked as a standard chemical artillery munition, being gray with two green, horizontal bands. It weighs 94.81 pounds (43.0 kg) in total and is filled with 11.7 lb (5.3 kg) of distilled mustard (HD). This version of the shell was designed as a chemical weapon delivery system.

It is a 26.8 inches (68.1 cm) steel shell with a rotating band near the base, and a burster well that goes down the center of the shell. The M104 (along with the M110, which it shares many design elements with) was designed as a 155 mm artillery shell for use in the M114 howitzer. In the United States, the military began focusing on replacing the European-made 75 mm artillery shells with 105 mm and 155 mm shells. ![]()
