Ha-1-class submarine
The was an early class of submarines of the Imperial Japanese Navy, and were essentially British C-class submarines, which had been imported for evaluation and reverse engineering.
==Background==
Following its experiment during and after the Russo-Japanese War with modified versions of the ''Holland''-class vessels designed in the United States, the Imperial Japanese Navy turned to the United Kingdom, which had continued development of the Holland design with 13 vessels in its A-class, 11 vessels in its B-class and 38 vessels in its C-class. The Japanese government contracted Vickers at Barrow-in-Furness for two vessels, which were laid down just after towards the end of the C-class production run for the Royal Navy. The completed vessels were shipped to Japan on a specially modified cargo vessel.
With limited endurance and only a ten percent reserve of buoyancy over their surface displacement, The Ha-1 class were poor surface vessels, but their spindle shaped hull made for good underwater performance compared to their contemporaries. They also had three times the displacement of their predecessors in the Imperial Japanese Navy, and were the first submarines considered usable as combat vessels by the Japanese.
