What's the point of this? Sunken warships are cemeteries. There are well over 100 U.S. Navy ships on the bottom of the Pacific that were sunk by the Japanese. Let them all be.
I’ve done 9 dives in Truk lagoon..impossible to describe..
Merely visiting a sunken warship is no different, IMO, to visiting a cemetery and paying respects to those who are buried there. Trying to raise such a ship, OTOH, to me would be akin to exhuming a dead body.
