The Japanese destroyer Aoi (葵) was one of 21 Momi-class destroyers built for the Imperial Japanese Navy (IJN) in the late 1910s. She was converted into a patrol boat in 1940 and was lost during the Battle of Wake Island shortly after the beginning of the Pacific War in December 1941.

Design and description

The Momi class was designed with higher speed and better

kW) to give the ships a speed of 36 knots (67 km/h; 41 mph). The ships carried a maximum of 275 long tons (279 t) of fuel oil which gave them a range of 3,000 nautical miles (5,600 km; 3,500 mi) at 15 knots (28 km/h; 17 mph). Their crew consisted of 110 officers and crewmen.^[4]

The main armament of the Momi-class ships consisted of three

12-centimeter (4.7 in) 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 superstructure. The guns were numbered '1' to '3' from front to rear. The ships carried two above-water twin sets of 533-millimeter (21 in) 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.^[2]

In 1940, Aoi was converted into a patrol boat. Her torpedo tubes,

ballast had to be added which increased her displacement to 950 metric tons (935 long tons).^[5]^[6]
