Fire Control Towers (FCT's) were constructed along the coasts of Delaware and New Jersey to serve as the "eyes" of Fort Miles which was part of the Harbor Defense of the Delaware during WWII.
The FCT's were equipped with Azimuth Scope's (M1910A1) used to determine the range from a baseline (created by two FCT's). An additional scope in the tower would plot splashes from missed shots and give corrected azimuth and range information so adjustments could be made.
A time interval bell would ring every 15 to 30 seconds (depending on the battery reload times) at which time a new reading would be taken by the FCT crews. This would allow the plotting rooms to track and triangulate a target's course and to better direct fire.
