I'm not certain of the size
It's kind of hard to judge the size by looking at it. I'd guess it was somewhere from 40 to 60 feet in diameter. There weren't any bullet holes that I could see (which, given the location, IS kind of surprising). There was a panel missing but the owner probably has it. I don't know about the condition or availablity of any of the electronics, but that stuff may be too old to be useful.
