Early 60s, with a R-7/SS-6 or R-16/SS-7 with 5Mt warhead, it would, however, have caught fire (along with the reat of the town)
And with a CEP of 2NM, a "miss" on NYC in the wrong direction may have moved it close enough for the blast to have brought down buildings as well.
Your CEP comment is exactly correct - the danger at 12 miles was not from a hit, it was from a miss.
The technical details and capabilities of russian missiles/bombs are subjuct to more than a little dispute.

OB, thanks for the info.
Patton, my original contention was that at 12 miles radius, we would have been incinerated—which is like what happens when your whole town catches fire at once.
Anyway, at 5MT to 10 MT, a not unthinkable yield for hydrogen air blast detonation over NYC, the results at 12 miles radius were most likely not survivable.
Even if you were in a basement and somehow missed the initial blast effects, the radiation would have gotten you with a fatal exposure in as little as 25 minutes.
I didn’t realize that their CEP was that tight in the 60s.
