I was reading the other day that one of the missiles hit the compartment where damage control and power distribution was managed for the whole ship. No power, no propulsion, no way to fight the fire.
excerpt, diagrams in the link:
1) Two missiles, possibly three, hit the cruiser dang near amidships.
2) The missile that struck near the waterline on the port side either exploded in the forward engine room that housed the cruising gas turbines and steam turbines (#47) or it detonated in a compartment that is their main damage control space (#45). This compartment also is a major node in the ship's electrical distribution system. The worst case would be if the missile exploded in #45 as this would have taken out both engine rooms and the central damage control with a single hit.
3) The second missile appears to have struck the ship a bit higher and could have detonated in the 30mm AK-630 magazines. If rounds started cooking off, they could have caused considerable secondary damage and casualties.
4) It's possible one of the three electrical generating compartments was also damaged (#48).
5) It is probable that the lower missile hit caused a complete loss of propulsion and electrical power and disabled their damage control capability. Basically, this ship suffered an immediate mission kill. With the loss of all electrical power and DC central in severe disarray the fire wasn't contained and it spread aft. Not sure how far back the fire boundary went, but smoke clearly propagated aft along what looks like passageways outboard of the S-300 [SA-N-6] magazine. Flooding also occurred in at least the forward engine room. With the damage control space severely damaged, the ≈15° list to port could not be easily corrected and this only allowed more water into the ship. Regardless of whether or not she sank, Moskva would need to be towed back to port.
6) I toured Moskva's sister ship, Marshal Ustinov, back in 1989 and I was amazed with the lack of damage control gear I saw on the main deck and immediately inside the ship's superstructure. I vividly recall seeing few fire fighting connections. I only found three double hose connections on each side and they were smaller than our standard 2.5-inch hose. There may have been another double connection further forward, I couldn't go very far past the 130mm gun mount. One double hose connection was under the second set of P-1000 [SS-N-12 Mod 1] launch tubes!
