The mid conning tower section from Ha 14. This element shows evidence of the explosive charge used by the crew to destroy their submarine. The submarine's hull is constructed of 6.4 mm steel plate. The operational equipment within this component originally consisted of 1 gyro compass, 1 magnetic compass, 1 radio receiver, 1 radio transmitter and underwater listening gear.
This is the mid section from HA-14, one of the three Type A midget submarines which entered Sydney Harbour in 1942. These submarines were produced for the Japanese Navy between 1938 and 1942, and were designed to be launched from warships during major fleet actions and were carried by Chitose class seaplane tenders and C1 Type submarines. No generators were fitted to these midgets, so that recharged batteries could only be fitted by a dockyard or a mothership. During the war many additions were made to individual craft in the form of jumping wires, propeller guards, net cutters etc., which gradually reduced their serviceable speed.
The most notable actions undertaken by these submarines were at Sydney Harbour, Pearl Harbour and Diego Saurez.
