Notable for me in the photo above:
1. The 3R41 Volna (NATO Top Dome) fire control radar for the S-300F Fort (NATO SA-N-6a Grumble) air defence system in its usual, standby position, rather than appearing to have been in the process of engaging anything.
2. The Osa-2M (NATO SA-N-4b Gecko) air defence systems, on either side of the hangar, are still in their retracted positions inside their cylindrical enclosures, rather than appearing to have been in the process of engaging anything.
This seems to be strongly suggestive of a ship that was caught entirely by surprise.
The area of the apparent damage/fire -- just aft of the P-1000 Vulkan (NATO SS-N-12 Sandbox mod 2) antiship missile launchers, and just ahead of the funnels -- makes sense for a missile(s) hit. Given that active radar guided antiship missiles (like Neptun) would ordinarily home on the centroid of the radar return.
Notably, there are a pair of AK-630M CIWS in this area, lending more credence to the idea that the air defences of Moskva were completely surprised.
