Nike Missile Philadelphia Defense Area
Nike batteries built in the mid-1950s to defend the eastern approaches to Philadelphia were: (PH-25) Lumberton, (PH-32) Marlton, (PH-41) Berlin/Clementon, (PH-49) Pittman, and (PH-58) Swedesboro. Headquarters facilities were located at Fort Dix and Fort Mott.
The Philadelphia District of the Army Corps of Engineers oversaw the construction of these sites. Initially, Regular Army troops manned the batteries, then many were shifted to the National Guard. Sites PH-25, PH-41, and PH-58 were upgraded to launch Nike Hercules missiles and remained active until 1974.
