Sisters' Point Base-End / Radar Station - Location 149

B9/2 S9/2 and B5/1 S5/1 Fort Dearborn - B4/6 S4/6 Fort Foster

This five-story concrete tower was completed in July 1942 on a government-owned 4.71 acre site as a combined Base-End Station for Fort Foster and Fort Dearborn. The Army barracks was not attached to the tower. The fifth-story observation level was intended for Battery 205 (B4 S4), the fourth-story level was for Battery 204 (B5 S5), and the third-story level was for Battery 103/Seaman (B9 S9). The fifth level was later changed to the HD OPS 3 station for the Portsmouth Harbor Defense Operations Command. The roof deck/balcony was used for the anti-aircraft intelligence service (AAIS OP 8). Searchlight positions #13 and #14 were located southwest and southeast of the tower. An SCR-296A fire-control radar on a 100-foot tall steel-frame tower, with an adjoining concrete-block operating room, was located on the north-side of the concrete tower. An SCR-268 mobile radar unit was set up in 1944 southeast of the concrete tower, adjacent to searchlight #14. The concrete tower, located at the end of Goodwin Road, was demolished by the new landowners in May 2004. There are no visible remains today.
