Actually, Chief, I was taken back to the 60's when I served almost three years on Herc bases, one was LA-55 near Point Vicente, California. That one was, I think Btry D, 3rd msl bn, 47th Artillery, later Air Defense Artillery. When we turned that one over to the NG, I was sent to Btry A, 1st msl bn, 56th Artillery, which moved to Fort Bliss as Headquarters. I think that site was LA-94 at Newhall, Calif up in the mountains. It was still going strong when I left the service in `65.
I was in IFC all of my tour as Acquisition Radar operator as well as the Computer. I locked onto and queried aircraft with the IFF system. After an aircraft was considered hostile, the TTR locked on with a smaller, more powerful signal. Then when the pits had a bird on the launch rails and reported to the BCO, the MTR locked onto the missile and sent and received flight instructions via the computer.
In 1963, we had a few high yield warheads installed on some of the missiles. One way to tell one of those was the nose probe which was a barometric arming device with a shield over it which was removed during launch preparations. As they say, I can't confirm that any nukes were ever on a Nike site. Different Arm Plugs were installed depending on the mission.
Few people know that a Herc knocked down another missile at White Sands, I believe it was a Corporal.
This is a good site for info and history.
