Indeed! Much in the way that Hood was upgraded over the years. The Yamato's were the only really modern ships and to large too risk. A ship not worth risking is of no value at all. That Nimitz sent "Ching" Lee into the tight waters off Guadalcanal was certainly a calculated risk, the kind you might use when you need the Hail Mary pass.
Indeed it was.
I had long wondered why they were so concerned about the channel (slot) up the Solomons, and Savo Sound next to Guadalcanal.
Until I began working on a supplement for a Wargame (
Advanced Squad Leader) that required buying some actual Maps of the Islands and the Oceans surrounding them that dated from Pre-WWII to 1945.
And I was shocked to see the Oceanographic Maps of that Area, both the “Pre-1941” Maps, AND the “Accurate” Post-War maps of the same waters.
The Pre-1941 Maps showed a LOT of water hazards in Savo Sound, AND in the rest of the Solomon Island Chain, where you might have a bottom that is 50 fathoms, only to have some gigantic outcropping of rock that shoots-up to a depth of 18’, before dropping back into an abyss.
And many of these could be a mile or more offshore.
I learned that the way rock erodes in water is very different than on land, and that you are more likely to get these rock massifs than you are on land. ESPECIALLY anywhere that Coral Grows, as the Coral tends to build-up on the harder Rock, thus creating a positive/negative-feedback effect upon the geological strata underwater (the Coral tends to remain on the harder rocks, as that on the softer rocks is more likely to have the rock beneath it fall off. Thus the harder rocks at track more coral, making them even harder in the process, and making them grow toward the surface).
Seeing the Pre-WWII Maps (most of which Dated to the 19th Century, if not earlier in the 18th Century) was scary enough looking.
But when I saw the Modern, accurate Oceanographic Survey Maps, I wondered how they managed to loose so few ships to collisions with submerged coral heads, or other navigational hazards that were not marked on the earlier maps (Oh! And then there is the “We are three miles inland” problem with many of the Maps. They had some Islands located several minutes away from the Lat-Long position. So while the coast of an Island in the chain might run SE to NW beginning at 8° 26' 43.1154" S, 157° 53' 48.984" E, the Maps will have it at 8° 20' 43.1154" S, 157° 55' 48.984" E.
Meaning you could run into it as it would be about 6 miles closer, if you were traveling SW from the NE, than the Map indicated.
That was a very risky move to send ships that were not just “Fat” in terms of their turning radius, but also that sat so deep in the water.
The Japanese ships tended to sit even deeper, given how overweight many were.
