二次世界大戰資料庫 (WW2DB)

ww2dbaseLieutenant Iwasa Naoji was a submarine officer. At the attack on Pearl Harbor, his midget submarine, crewed by Naokichi Sasaki, was launched from I-22 nine miles from the American base. Originally the midget submarines were to provide intelligence before and during the attack, and they were only to launch their torpedoes after the attack after sundown. However, at the last moment, Lieutenant Naoji Iwasa who commanded the submarines asked for the permission to launch the attack during the actual aerial raid, which was accepted by his superiors, therefore essentially changing the role of the midget submarines into suicidal weapons.
