6-inch gun M1897

The 6-inch gun M1897 (152 mm) and its variants the M1900, M1903, M1905, M1908, and M1 (aka T2) were coastal artillery pieces installed to defend major American seaports between 1897 and 1945. For most of their history they were operated by the United States Army Coast Artillery Corps. They were installed on disappearing carriages or pedestal (aka barbette) mountings, and during World War II many were remounted on shielded barbette carriages.〔(Coast Defense Study Group fort and battery list )〕 Most of the weapons not in the Philippines were scrapped within a few years 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 in its 1886 report and 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. The 6-inch caliber was chosen, as in many applications, for combining a relatively heavy shell with rapid hand loading. In the overall system, it was an intermediate caliber between the heavy 8-inch, 10-inch, and 12-inch weapons and the small 3-inch guns intended to defend minefields against minesweepers. The Watervliet Arsenal designed the guns and built the barrels. Initially, most of the guns were mounted on disappearing carriages; when the gun was fired, it dropped behind a concrete and/or earthen wall for protection from counter-battery fire. Within a few years, it was realized that operating the disappearing carriage negatively impacted the rate of fire, and the M1900 low-profile pedestal mount was designed.
On the outbreak of the Spanish–American War in 1898 most of the Endicott fortifications were still under construction. To quickly arm some works a few weapons were purchased from the United Kingdom including 13 6-inch Armstrong guns, two of which survive at Fort DeSoto near St. Petersburg, Florida. These appear to have been withdrawn from service by 1925.
Between the Endicott program and the 1905–15 Taft Board fortifications, approximately 200 6-inch guns were emplaced in the United States and its possessions, around 150 of which were on disappearing carriages.
