How did the US Navy intend to use nuclear shells carried by Des Moines-class cruisers?
Short answerPrimarily against shore targets, with massed enemy shipping as a possible secondary target.
NotesCoastal targets are the more likely mission for nuclear eight-inch ammunition. A large concentration of enemy ships could also become a secondary target. The shells would give a Des Moines-class cruiser a nuclear shore-strike role alongside a possible anti-fleet mission. No more detailed employment plan appears in this passage.
