Here is a close up of the Cape Povorotnyy area for the squints out there. Bring your own light table:
A closer look at the facilities:
I'm no imagery analyst, but these look like bermed firing positions for mobile coastal defense missiles. Or they could be reveted helo pads/parking positions, who knows.
The big open field in the north of the photo looks like antennas or lightning arresters to me. What all the vehicles are doing in the south of the photo is a mystery to me.
Wikimapia identifies this facility as the Cape Povorotnyy lighthouse.
The closure is a little less than 20NM long. That would be a good range for a coastal defense cruise missile shot or maybe even a SAM vs. Drone.
We'll see if anything pops up later in the week to confirm that this closure was actually used.
