The wreck of the USS Indianapolis HAS been found!
Paul Allen billionaire cofounder of Microsoft and 'amateur' hobbyist explorer found it today.
His last big find was the Musashi. Finding Indianapolis is more impressive from a technical perspective, because its a smaller ship found at a greater depth then Musashi was found, though still only half the depth of Titanic.
The livestreamed for Musashi had more views then this one, and got more news coverage for that (though still not that much news on big news sites), and more talk on warship forums.
I think only really hobbyist people were that super interested in Musashi, so even less are probably super interested in Indie. And even alot of those hobbyists probably aren't as interested in a cruiser as much as a battleship.
The Yamato class also has a sort of memetic legendary reputation in their idea of them, especially with the respect lots of anime give them. A cruiser wouldn't bring that much awe and respect. It's considered smaller, less powerful, and less significant and grand.
Especially one associate with nukes, which many find distasteful, and most famous in wider modern fad pop culture for sharks in the film JAWS instead of actual accomplishments.
It's a shame that Indianapolis doesn't have a popular personification. Lots of animesque fanart was made for Musashi finding to commemorate that, showing her with Paul Allen and others.
There are less popular personifications of Indianapolis, but the fact they're from less popular series, or a less popular ship, means probably little to no content or discussion of the event.
Though I have found a small group of western artists did draw the warship itself in a sketch collaboration project.
