I was in a whaleboat rescuing survivors the night of the Belknap fire (Boat Engineer, A-gang, USS Ricketts DDG5).
I remember seeing the superstructure the morning after and noting the extreme amount of damage from the aluminum melting. The forward smoke stack had actually melted and folded down upon a loaded ASROCK launcher. Had it been steel, some of the fire might have been contained and been easier to fight.
