Did the G3, N3, and K3 designs influence Japan's navy in the 1930s?
Short answerProbably not directly, because Britain did not share those design studies; Nelson is a more plausible influence.
NotesNelson is considered a possible influence on Japanese naval thinking in the 1930s. Direct influence from the G3, N3, or K3 studies is judged unlikely because Britain did not share those designs. Japanese access to the British work is the deciding issue.
