I think you are right/ that might be “original” whereas the one on the bottom has many bomb hits. It was scuttled by the Japanese DDs, but bombers from the Enterprise savaged it.
I thought the KAGA was found in 1999 or so
A Japanese submarine was patrolling the area at the time. The American fleet had just passed. They could have radioed Tokyo had they seen it earlier. The outcome of the war could have been different.
