That’s a sorry looking (former?) airbase in the picture.
Isn’t it?
That area was the HQ and training center for the Soviet Amphibious forces. You can see the hovercraft landing docks if you look along the shore near the Ukrainian Naval port. (You can’t really call it a “Base”. There is no heavy equipment, just a (floating drydock.)
You can see that both sides of the entrance were at one time covered with launchers, as well as a large number of SAM sites.
Between here, and the Balaklava Sub Base, one wonders how many western intelligence operators died trying to find out what was there, only to find it open and abandoned now.
