What it is

HA. 19 is a historic Imperial Japanese Navy Type A Kō-hyōteki-class midget submarine that was part of the Japanese Attack on Pearl Harbor on 7 December 1941. The submarine's crew was ordered to enter Pearl Harbor, attack the moored American warships with its two torpedoes and then scuttle her with explosives. However, the crew was unable to enter the harbor due to navigational difficulties, and the submarine ran aground and was captured by American forces.

Wilderness Atlas publishes a centroid and an acreage for each unit, not a boundary line. Distance here is measured to a circle of the same area drawn around that centroid, so treat it as roughly right rather than surveyed.
