Fort William and Mary was a colonial fortification in Britain's worldwide system of defenses, defended by soldiers of the Province of New Hampshire who reported directly to the royal governor. The fort, originally known as "The Castle," was situated on the island of New Castle, New Hampshire, at the mouth of the Piscataqua River estuary. It was renamed Fort William and Mary circa 1692, after the accession of the monarchs William III and Mary II to the British throne. It was captured by Patriot forces, recaptured, and later abandoned by the British in the Revolutionary War. The fort was renamed Fort Constitution in 1808 following rebuilding. The fort was further rebuilt and expanded through 1899 and served actively through World War II.

The fort was renamed for the U.S. patriot commander in the Battle of Sullivan's Island, General William Moultrie. During British occupation, in 1780–1782, the fort was known as Fort Arbuthnot.

The 12-inch coastal defense gun M1895 (305 mm) and its variants the M1888 and M1900 were large coastal artillery pieces installed to defend major American seaports between 1895 and 1945. 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.
Battery Steele is a United States military fortification on Peaks Island, Portland, Maine in Casco Bay. Completed in 1942 as part of World War II, it is located on 14 acres (5.7 ha) on the oceanside area of the island, formerly part of the Peaks Island Military Reservation. It is named for Harry L. Steele, who was a Coast Artillery officer during World War I. It was armed with two 16-inch MkIIMI guns and, with a 12-inch gun battery at Fort Levett on Cushing Island, replaced all previous heavy guns in the Harbor Defenses of Portland. It was built to protect Casco Bay, particularly Portland harbor, from Kennebunk to Popham Beach in Phippsburg. According to Kim MacIsaac and historian Joel Eastman in An Island at War, “Battery Steele is not only the largest gun battery built on Peaks Island, but also an example of the largest battery ever built anywhere in the United States.” In 1995, after decades of non-use, the Peaks Island Land Preserve, a community land preservation group, formed to purchase the area and forever preserve it as a public space. On October 20, 2005, the property was listed on the National Register of Historic Places. Other coast defense structures on the island include fire control towers and the counterweight for a disappearing searchlight tower.

They were installed on balanced pillar or pedestal mountings; generally the M1897 was on the balanced pillar mounting and the M1900 was on the pedestal mounting. All of these weapons were scrapped within a few years after World War I.
