The Japanese destroyer Hagi (萩) 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 seakeeping than the preceding Enoki-class second-class destroyers.^[1] The ships had an overall length of 280 feet (85.3 m) and were 275 feet (83.8 m) between perpendiculars. They had a beam of 26 feet (7.9 m), and a mean draft of 8 feet (2.4 m). The Momi-class ships displaced 850 long tons (864 t) at standard load and 1,020 long tons (1,036 t) at deep load.^[2] Hagi was powered by two Parsons geared steam turbines, each driving one propeller shaft using steam provided by three Kampon water-tube boilers.^[3] The turbines were designed to produce 21,500 shaft horsepower (16,000 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, Hagi 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 (1 in) Type 96 light AA guns and 60 depth charges. In addition one boiler was removed, which reduced her speed to 18 knots (33 km/h; 21 mph) from 12,000 shp (8,900 kW). These changes made her top heavy and ballast had to be added which increased her displacement to 950 metric tons (935 long tons).^[5]^[6]

Construction and career

Hagi, built at the Uraga Dock Company shipyard in Uraga, was laid down on February 28, 1920, launched on October 29, 1920, and completed on April 20, 1921. During 1940, she was converted into a patrol boat and was renamed Patrol Boat No. 33 on April 1. The ship was deliberately run aground on 23 December 1941 during the second Battle of Wake Island at coordinates 19°17′N 166°37′E / 19.283°N 166.617°E / 19.283; 166.617 to allow her Special Naval Landing Force troops to disembark. Nearby Marine anti-aircraft guns then set her on fire. Patrol Boat No. 33 was struck from the Navy List on 15 January 1942.^[5]
