The front foyer of the armory has doors on the left and right leading to various offices. The buildings act as a buffer between the mainland and the Fort Strong armory on the southern tip of the archipelago. Outside of the base are over half a dozen bombed out buildings, infested with super mutants.

As of 2287 the military facility was occupied by super mutants, until the Battle of Fort Strong. Most notably, the M42 Fat Man and its nuclear payloads were developed here. Live weapons testing began in the 2070s, after they tore down the historic barracks and constructed modern civilian buildings at the base of the armory. It was quietly reoccupied by the military in the 2050s as a top-secret weapons research facility the interior was retrofitted and a basement level was dug to house the new laboratories and a sizable armory. It was declared surplus in 1947 and abandoned since the 1950s. During World War II however all its big guns and all but two of its small gun batteries – that defended channel minefields – were decommissioned. When a large station for handling submarine mines and an anti-aircraft battery was added to the fort's defenses, and manned by over one thousand soldiers. The fort was modernized as part of the Endicott period, however its peak was before World War I. The site of Fort Strong was used by the American patriots during the Revolution as an artillery battery and the fort itself dates back to the American Civil War.
