A fire control tower is a structure located near the coastline, used to detect and locate enemy vessels offshore, direct fire upon them from coastal batteries, or adjust the aim of guns by spotting shell splashes. Fire control towers came into general use in coastal defence systems in the late 19th century, as rapid development significantly increased the range of both naval guns and coastal artillery. This made fire control more complex. These towers were used in a number of countries' coastal defence systems through 1945, much later in a few cases such as Sweden. The Atlantic Wall in German-occupied Europe during World War II included fire control towers.
Fort Wetherill is a former coast artillery fort that occupies the southern portion of the eastern tip of Conanicut Island in Jamestown, Rhode Island.

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.

Fort Saulsbury was named for Willard Saulsbury, Sr., a former US Senator from Delaware.
The Harbor Defenses of the Delaware was a United States Army Coast Artillery Corps harbor defense command. It coordinated the coast defenses of the Delaware River estuary from 1897 to 1950, beginning with the Endicott program. These included both coast artillery forts and underwater minefields. The areas protected included the cities of Philadelphia, Camden, and Wilmington along with the Chesapeake & Delaware Canal. The command originated circa 1896 as an Artillery District and became the Coast Defenses of the Delaware in 1913, with defenses initially at and near Fort Delaware on Pea Patch Island near Delaware City. In 1925 the command was renamed as a Harbor Defense Command. During World War II the defenses were relocated to Fort Miles on Cape Henlopen at the mouth of the Delaware Bay.
