Japanese destroyer Yomogi

The Japanese destroyer Yomogi (薄) was one of 21 Momi-class destroyers built for the Imperial Japanese Navy (IJN) in the late 1910s. In 1940, she was converted to Patrol Boat No. 38. The ship was torpedoed in the Bashi Strait by USS Atule on November 25, 1944, and stricken from the navy list on March 10, 1945.

Design and description
The Momi class was designed with higher speed and better seakeeping than the preceding Enoki-class destroyer second-class destroyers. The ships had an overall length of 280 ft and were 275 ft between perpendiculars. They had a beam of 26 ft, and a mean draft of 8 ft. The Momi-class ships displaced 850 LT at standard load and 1020 LT at deep load. Yomogi was powered by two Zoelly geared steam turbines, each driving one propeller shaft using steam provided by three Kampon water-tube boilers. The turbines were designed to produce 21500 shp to give the ships a speed of 36 kn. The ships carried a maximum of 275 LT of fuel oil which gave them a range of 3000 nmi at 15 kn. Their crew consisted of 110 officers and crewmen.

The main armament of the Momi-class ships consisted of three 12 cm 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 mm 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.

In 1940, Yomogi was converted into a patrol boat. Her torpedo tubes, minesweeping gear, and aft 12 cm gun were removed in exchange for two triple mounts for license-built 25 mm Type 96 light AA guns and 60 depth charges. In addition one boiler was removed, which reduced her speed to 18 kn from 12000 shp. These changes made her top heavy and ballast had to be added which increased her displacement to 935 LT.

Construction and career
Yomogi, built at the Ishikawajima shipyard in Tokyo, was laid down on 26 February 1921, launched on 14 March 1922, and completed on 19 August 1922. In 1940, she was converted into patrol boat and she was renamed Patrol Boat No. 38 (第三十八号哨戒艇, Dai-38-Gō shōkaitei) on 1 April 1940: She was torpedoed in the Bashi Channel by the United States Navy submarine USS Atule on 25 November 1944 and was struck from the navy list on 10 March 1945.
