The **Japanese destroyer *Warabi*** (蕨) was one of 21 [*Momi*-class](/source/Momi-class_destroyer) [destroyers](/source/Destroyer) built for the [Imperial Japanese Navy](/source/Imperial_Japanese_Navy) (IJN) in the late 1910s. The ship was sunk on August 24, 1927 in a collision with the cruiser [*Jintsū*](/source/Japanese_cruiser_Jints%C5%AB) off [Miho Bay](/source/Miho_Bay), and was struck from the naval list on September 15, 1927.

## Design and description

The *Momi* class was designed with higher speed and better [seakeeping](/source/Seakeeping) than the preceding [*Enoki*-class](/source/Enoki-class_destroyer) second-class destroyers.[1] The ships had an [overall length](/source/Length_overall) of 280 feet (85.3 m) and were 275 feet (83.8 m) [between perpendiculars](/source/Between_perpendiculars). They had a [beam](/source/Beam_(nautical)) of 26 feet (7.9 m), and a mean [draft](/source/Draft_(hull)) of 8 feet (2.4 m). The *Momi*-class ships displaced 850 [long tons](/source/Long_ton) (864 [t](/source/Tonne)) at [standard load](/source/Displacement_(ship)#Standard_displacement) and 1,020 long tons (1,036 t) at [deep load](/source/Deep_load).[2] *Warabi* was powered by two [Parsons](/source/Parsons_Marine_Steam_Turbine_Company) geared [steam turbines](/source/Steam_turbine), each driving one [propeller shaft](/source/Propeller_shaft) using steam provided by three [Kampon](/source/Kampon) [water-tube boilers](/source/Water-tube_boiler).[3] The turbines were designed to produce 21,500 [shaft horsepower](/source/Horsepower#Shaft_horsepower) (16,000 [kW](/source/Kilowatt)) to give the ships a speed of 36 [knots](/source/Knot_(unit)) (67 km/h; 41 mph). The ships carried a maximum of 275 long tons (279 t) of [fuel oil](/source/Fuel_oil) which gave them a range of 3,000 [nautical miles](/source/Nautical_mile) (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](/source/Type_3_120_mm_45_caliber_naval_gun) in single mounts; one gun forward of the [well deck](/source/Well_deck), one between the two [funnels](/source/Funnel_(ship)), and the last gun atop the aft [superstructure](/source/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](/source/Torpedo_tube); 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]

## Construction and career

*Warabi*, built at the [Fujinagata Shipyards](/source/Fujinagata_Shipyards) in [Osaka](/source/Osaka), was laid down on October 12, 1920, [launched](/source/Ceremonial_ship_launching) on September 28, 1921 and completed on December 19, 1921. The ship was sunk on August 24, 1927 in a collision with the cruiser [*Jintsū*](/source/Japanese_cruiser_Jints%C5%AB) off [Miho Bay](/source/Miho_Bay), and was struck from the naval list on September 15, 1927. In the collision and sinking, 119 people died.[5]

## Wreck

In September 2020 researchers discovered what they concluded is the forward section of *Warabi* 33 kilometres (21 mi; 18 nmi) to the northeast of the Mihonoseki Lighthouse, [Shimane Prefecture](/source/Shimane_Prefecture), noting that the ship had broken in two in the collision,. The aft part was located in July 2021, 10 kilometres (6.2 mi; 5.4 nmi) north of the bow.[5]
