Nagato as of 1941:
Extensively refitted Like Mutsu Nagato can be distinguished from her sister because of her completely different aft superstructure, also many other small differences around the bridge and pagoda mast further made the sips look quite unique from one to the other.
Under command of Admiral Isoroku Yamamoto IJN Nagato was the flaghsip of the combined fleet until february 1942; it was from this battleship that, on december 2nd 1941, admiral Yamamoto ordered the Kido Butai (carrier strike force), by signaling
"Niitaka yama nobore" (Climb Mount Niitaka), to attack Pearl Harbour.
