6-inch gun M1897

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.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.To quickly arm some works a few weapons were purchased from the United Kingdom including nine 6-inch Armstrong guns, two of which survive at Fort DeSoto near St. Petersburg, Florida.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.Many 6-inch weapons (most of them stored since World War I) were remounted on M1 through M4 shielded barbette carriages at new locations in two-gun batteries to complement the 16-inch guns.[13] Some additional 6"/50 caliber ex-Navy guns were mounted in the year after Pearl Harbor to provide some defense while the new batteries were under construction; locations included Alaska, American Samoa, and Suriname (formerly Dutch Guiana) among others.
