For most of their history they were operated by the United States Army Coast Artillery Corps. Most were installed on disappearing carriages, with early installations on low-angle barbette mountings. From 1919, 19 long-range two-gun batteries were built using the M1895 on an M1917 long-range barbette carriage. Almost all of the weapons not in the Philippines were scrapped during and after World War II. History In 1885, William C. Endicott, President Grover Cleveland's secretary of war, was tasked with creating the Board of Fortifications to review seacoast defenses. The findings of the board illustrated a grim picture of existing defenses, and in its 1886 report recommended a massive $127 million construction program of breech-loading cannons, mortars, floating batteries, and submarine mines for some 29 locations on the US coastline. Most of the board's recommendations were implemented. Coast artillery fortifications built between 1885 and 1905 are often referred to as "Endicott Period" fortifications. thumb|left|M1895 coastal defense 12-inch gun on M1896 disappearing carriage. thumb|left|A coastal defense 12-inch gun on an M1895 disappearing carriage, showing raised and lowered positions. Watervliet Arsenal designed the gun and built the barrels. For several years, difficulties were encountered in building a disappearing carriage for the 12-inch gun. One alternative was the M1891 gun lift carriage, with the gun mounted on a large steam-powered elevator. Only one battery of this type was built, Battery Potter at Fort Hancock, New Jersey. When this proved to be too complex, guns were mounted on low-angle M1892 or M1897 barbette carriages. The M1897 carriage was actually an "altered gun lift" carriage, functionally equivalent to the barbette carriage. Eventually, the guns were mounted on M1896, M1897, or M1901 disappearing carriages designed by Bethlehem Steel; when the gun was fired, it dropped behind a concrete or earthen wall for protection from counter-battery fire.FM 4-80 Seacoast Artillery: Service of the Piece – 12-Inch and 14-Inch Guns (Disappearing Carriage) Bethlehem later built barrels as well. Detailed descriptions of the M1888 weapon, disappearing carriage, and gun lift carriage are in the US Army's Artillery circular 1893, pp. 195–207. Detailed parts lists for the M1888 weapon and supporting equipment are in the Ordnance supply manual by George L. Lohrer, United States Army, Ordnance Dept, 1904, pp. 115–211. After the Spanish–American War, the government wanted to protect American seaports in the event of war, and also protect newly gained territory, such as the Philippines and Cuba, from enemy attack. A new Board of Fortifications, under President Theodore Roosevelt's secretary of war, William Taft, was convened in 1905. Taft recommended technical changes, such as more searchlights, electrification, and, in some cases, less guns in particular fortifications. The seacoast forts were funded under the Spooner Act of 1902 and construction began within a few years and lasted into the 1920s. The defenses of the Philippines on islands in Manila Bay were built under this program.Berhow, Mark A. and McGovern, Terrance C., American Defenses of Corregidor and Manila Bay 1898–1945, Osprey Publishing Ltd.; 1st edition, 2003; pages 7–8. Railway mounting thumb|left|A 12-inch M1895 railway gun. After the American entry into World War I, the army recognized the need for large-caliber railway guns for use on the Western Front. Among the weapons available were 45 12-inch guns, to be removed from fixed defenses or taken from spares. Twelve M1895 weapons were mounted on M1918 railway carriages (based on the French Batignolles mount) by mid-1919; it is unclear if any more were eventually mounted.America's Munitions 1917-1918, pp. 96–98 Hogg Ian V.

In 1941 they were declared "limited standard", and all but one were scrapped during the war. The survivor was used for experimental purposes at the Naval Surface Warfare Center Dahlgren Division until it was transferred to the U.S. Army Ordnance Training and Heritage Center at Fort Lee, Virginia in the 2000s.

Fourteen two-gun and two one-gun batteries were constructed with M1895 guns on the new M1917 long-range barbette carriage,Instructions for mounting, using and caring for Barbette carriage, model of 1917 for 12-inch gun, model of 1895 MI (1917) which allowed an elevation of 35 degrees, compared to 15 degrees for the disappearing carriages. This increased the range from 18400 yd m to 30100 yd m.Berhow, p. 61 Eleven of these batteries were in the continental United States, with two in Panama, one in Hawaii, and two one-gun batteries at Fort Mills on Corregidor in the Philippines.Coast Defense Study Group fort and battery listBerhow, pp. 224–226 The guns were originally in open mounts with protected magazines, but most were casemated against air attack, beginning in 1940 as World War II approached the United States. However, the batteries in the Philippines were not casemated, as the 1923 Washington Naval Treaty prohibited further fortification of US and Japanese Pacific-area possessions, and in 1940–41 there was a lack of resources to do so. In some cases, an M1916 75 mm gun was mounted atop a 12-inch gun for subcaliber training.Williford, pp. 80-83 World War II Along with other coast artillery weapons, the 12-inch guns in the Philippines saw action in the Japanese invasion in World War II. Since they were positioned against a naval attack, they were poorly sited to engage the Japanese (although the long-range batteries had 360° fire due to lack of casemates, the disappearing batteries had about 170° fire). Other limiting factors were that they had mostly armor-piercing ammunition, and the open mountings were vulnerable to air and high-angle artillery attack. thumb|300px|right|Victorious Japanese troops atop Battery Hearn on 6 May 1942 Three additional long-range casemated batteries were constructed during the war, at Fort Miles, Delaware, San Juan, Puerto Rico, and on Sullivan's Island near Fort Moultrie in the Harbor Defenses of Charleston, South Carolina. With the additional construction of 16-inch gun batteries at most harbor defenses, all guns on disappearing carriages were scrapped in 1943–44. The long-range batteries' guns were scrapped soon after the war ended.

The projectile weight for all M1895 guns was 1,046 pounds. Each shell used 318 pounds of powder, but this was varied depending on range. The projectile achieved a muzzle velocity of 2,250 feet per second. The M1901 disappearing carriage could elevate 15 degrees maximum; earlier models could not elevate that much until the rear mounting bracket was changed from a centerline to an upper position in the M1901. The M1901 could traverse 170 degrees, but some M1895MII emplacements could traverse 210 degrees. The M1895MII had a range of over 29,000 yards (26 kilometers).Berhow, Mark A. and McGovern, Terrance C.
