It looks like a fat target to me.
***Those old ships were heavy, steel hulls. Antiship missiles might be far less effective, plus it’s not carrying ammunition to blow up.
Most modern warships still have steel hulls. The Moskva did.
Some newer ships, rather notoriously, had aluminum superstructures, which proved to be a bad idea (Falklands).
The real problem with really old ships is poor compartmentalisation, to limit flooding, and poor damage control.
Then there is armor, which might have saved the Moskva. Its gone out of fashion. This recovery ship though, being a Naval Auxiliary, is almost certainly not armored either.
