Pretty optimistic, isn't it ?

Yamato had plenty of aircraft guns after the Japanese were educated by their ships sinking via planes. She went from having 24 AA guns to 150 across her decks, but they didn't have any sort of radar assistance aiming them, so it was kind of moot when you couldn't coordinate your fields of fire to shoot down planes. She reportedly only took out 10 planes during her final moments despite the increased presence of the AA guns. It still took the presence of 200-300 planes to down her, but the AA was mostly underwhelming overall.
