I posted a question asking if the expedition will explore Kirishima or Hiei, no response yet. The wrecks have been explore before, but its interesting to see the affects of Adm Lee and Washington's 16inch gunnery. http://www.navweaps.com/index_lundgren/Kirishima_Wreck_Analysis.pdf
Another study of the wreck by Robert Lundgren, he estimates Kirishima was hit by twenty 16 inch and numerous 5 inch shells, its not wonder she went down so quickly. Washington's shooting was good that night.
