The Japanese destroyer was one of 21 s built for the
Imperial Japanese Navy (IJN) in the late 1910s. In 1940, she was converted into a
No.31-class patrol boat
The were a class of patrol boats of the Imperial Japanese Navy (IJN), serving during World War II. 9 vessels were converted from s and 1 vessel was converted from a in 1940.
Background
In 1939, the IJN was liberated from London Naval Treaty, an ...
and renamed ''Patrol Boat No.34'' (第三十四号哨戒艇, Dai-34-Gō shōkaitei). She was sunk by American aircraft in July 1944.
Design and description
The ''Momi'' class was designed with higher speed and better
seakeeping than the preceding second-class destroyers. The ships had an
overall length of and were
between perpendiculars. They had a

standard load and at
deep load.

[Watts & Gordon, p. 260]
The main armament of the ''Momi''-class ships consisted of three
Type 3 guns in single mounts; one gun forward of the
well deck, one between the two
funnels, and the last gun atop the aft

. The guns were numbered '1' to '3' from front to rear. The ships carried two above-water twin sets of
torpedo tubes; one mount was in the well deck between the forward superstructure and the bow gun and the other between the aft funnel and aft superstructure.
