In the normal battery configuration, there were thirty Nike Hercules missiles in three different launcher locations, each battery location was support by a separate sensor area (this consist of the acquisition and tracking radars plus the Command and Control).
The three launcher locations, all within about a 1 kilometer area, each had an individual missile barn, holding ten missiles, with usually three missiles on the launcher rails that extended from the barn. One barn/launcher location had all conventional warheaded missiles, and in the other two barn locations, internal to the barn were two (2) each nuclear equipped missiles.
Those two missiles each (4 per battery) stay in the barn always, unless they were disassembled from the missiles and moved to the "warhead assembly building", for maintenance. The yield configuration of the "high order" missiles was decided at the (Commander in Chief, European Command) CINCEUCOM level, or probably the NORAD level, stateside. Actually, I am theorizing the US configurations based on the European and Korean experiences. You all know that Department of the Army operates on standards that are duplicated across the force. Several of you are correct, at one time Nike Hercules sites were distributed all over this nation. A great site that can answer a number of your questions is at

I appreciate your listening to me as I reminiscing about the 80s.
