Sorry but never could get in to the premised of raising a sunk Japanese ww2 battleship and making it a spaceship
1. It’s science fiction
2. “Yamato 2199” explains this
3. It’s a cultural thing
4. In the late 1990’s, Disney bought the movies rights to “Space Battleship Yamato” with a storyline of the USS Arizona (either parts of it or a replica) being resurrected as a rally cry for humanity. However, when Michael Eisner left Disney in 2005, the project was shelved and the movie rights expired. Toho picked it up in 2006.
