Fort Ruckman was a U.S. Coast Artillery fort located in Nahant, Massachusetts. Originally called the Nahant Military Reservation, the fort was laid out in 1904-1907 and covered an area of about 45 acres just northwest of Bass Point, on the southwest side of the Nahant peninsula.Nahant was also the site of two other World War II-era gun batteries, Battery Murphy (2 16-inch guns) and Battery 206 (2 6-inch guns). These batteries, along with three tall fire control towers, were located in the area called the East Point Military Reservation, at the extreme southeast end of the Nahant peninsula.

John Wilson Ruckman, a former Colonel in the Coast Artillery.Ruckman was an engineer in the late 1890s who argued against the "Abbot Quad" method of locating coast defense mortars and then firing them in 16-mortar salvos. He urged that mortars be aimed and fired individually, if fire control systems were up to this task. After 1910 or so, Ruckman's model became the norm. Read more on Wikipedia
