Trivia

This gun's basic structure was based on the British QF 4.7in. Mk.IV gun, which was later produced domestically in Japan. The barrel of this gun was later mated to a high-angle mounting and served as AA guns for early Japanese heavy cruisers (ie. Furutaka-class to Takao-class. Both classes had their AA guns exchanged for 12.7cm twin afterward, but Chokai alone was equipped with 12cm singles throughout her career).
