Submarines of the Imperial Japanese Navy
Imperial Japanese Navy submarines originated with the purchase of five Holland type submarines from the United States in 1904. Japanese submarine forces progressively built up strength and expertise, becoming by the beginning of World War II one of the world's most varied and powerful submarine fleets.
Japanese submarine I-41
I-41 was a Japanese B2 type submarine. She was completed at Kure Navy Yard on 18 September 1943, whereupon she entered into service with the Imperial Japanese Navy Yokosuka Naval District, SubRon 11, and sailed to Yokosuka for final trials under the command of Lt. Commander Tamori Yoshimatsu. This was completed by 15 December 1943 and command was transferred to Lt. Commander Itakura Mitsuma. "I-41" was reassigned to the Sixth Fleet in SubRon 1's Sub Division 15.
