Indeed, I was using all steel construction as the "best" case scenario here (survivability etc given its superior strength and overall material properties). Moskva would be of that traditional generation as well.
Everything doubly and triply applies etc for aluminium being used in significant parts or even the superstructure basis...not sure if any hulls are made (at this relative size class i.e frigates, destroyers, cruisers etc.) out of Al alloy, @Anmdt would be in better position to know
Useful reference for interested members regd steel vs aluminium in warships:
By the by, and freakishly coincidentally.... acquaintance of mine served on USS Belknap (mentioned in this paper a few times given its aluminium superstructure and accident's effect on it as case study)
Seeing what happened with Moskva, he told me this earlier:
Part of me has a slight twinge of sorrow seeing that particular ship go down because we (Belknap) and then-Slava were together at Malta in 1989 for the Presidential Summit.
A nice looking ship then and we had some limited exchanges on board each ship.
Obviously none of either crew is still in service.
Now both ships are reefs.
In closing - good shooting Ukrainians!!
In 2017 i got a chance to visit her sister, Varyag, honestly i am impressed by her. Well with what happened to her sister Moskva, what i can said is, all is fair during the war especially the Russian who started the mess first.
I just hope the war can be ended soon. And all of Russia know how grave their collective mistake this time
