Real World Information[]
Mutsu (陸奥), named after the eponymous province, was the second and last Nagato-class dreadnought battleship built for the Imperial Japanese Navy (IJN) at the end of World War I. In 1923, a year after commissioning, she carried supplies for the survivors of the Great Kantō earthquake. The ship was modernized in 1934–36 with improvements to her armor and machinery, and a rebuilt superstructure in the pagoda mast style.
