Attack on Sydney Harbour [SEP] Flaws in Japanese tactics
The main flaw in the Japanese plans was the use of midget submarines for the primary attack. Midget submarines were originally intended to operate during fleet actions: they would be released from modified seaplane carriers to run amok through the enemy fleet. This concept went out of favour as changing Japanese naval thinking and experience led to recognition that naval warfare would centre around carrier-supported aerial combat. As a result, the midget program's focus changed to the infiltration of enemy harbours, where they would attack vessels at anchor. This concept failed completely during the attack on Pearl Harbor, where the midgets had no effect, and tying up 11 large submarines for six weeks in support of further midget submarine attacks on Sydney and Diego Suarez proved a waste of resources.
