Ōtori-class torpedo boat
The Ōtori-class torpedo boat (鴻型水雷艇, Ōtori-gata suiraitei) were a class of eight fast torpedo boats of the Imperial Japanese Navy built before and operated during World War II. == Development == To circumvent the terms of the 1930 London Naval Treaty, which limited its total destroyer tonnage the Imperial Japanese Navy designed the Chidori class torpedo boat, but planned to arm it with half the armament of a Fubuki class destroyer. The resultant design was top-heavy and unstable, resulting in the 1934 Tomozuru Incident, in which one of the Chidori-class vessels capsized.
