@donaldtoo , not far from where I grew up in MA, was a Nike Ajax B-55 site on top of a hill (fenced off, guarded, restricted area). Nike Ajax 30 / 10 per launcher section; 12 mounted on launchers (4 per section). 3 Magazines; 1 type B, 2 Ajax. Dates of operation were from 1955 through 1963. I think the Army is in charge of that site.
Incidentally, even when they shut it down, the locals in the area were convinced that they never removed the weapons; that they are still underground there, and could be used if needed.
