An anti-aircraft spotting station and an SCR-271 early-warning radar were located on Mount Agamenticus, adjacent to the old US Forest Service fire-spotting tower. Although not officially under the command of the Portsmouth Harbor Defenses, the site was manned by 25 soldiers of the 551st Battalion, U.S. Army Signal Corps. No visible remains, except for the radar tower's concrete footings. The last remaining buildings were demolished in the 1980's.
Located at Mount Agamenticus, York, Maine.
