The Momi class was designed with higher speed and better seakeeping than the preceding second-class destroyers.[1] The ships had an overall length of 280feet and were 275feet between perpendiculars. They had a beam of 26feet, and a mean draft of 8feet. The Momi-class ships displaced 850lk=onNaNlk=on at standard load and 1020LT at deep load.[2] Momi was powered by two Brown-Curtis geared steam turbines, each driving one propeller shaft using steam provided by three Kampon water-tube boilers.[3] The turbines were designed to produce 21500shp to give the ships a speed of 36kn. The ships carried a maximum of 275LT of fuel oil which gave them a range of 3000nmi at . Their crew consisted of 110 officers and crewmen.[4]
The main armament of the Momi-class ships consisted of three 12adj=onNaNadj=on 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 533adj=onNaNadj=on 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]
Momi, built at the Yokosuka Naval Arsenal, was launched on 10 June 1919 and completed on 27 December. She was stricken from the Navy List on 1 April 1932 and became an experimental hulk at Yokosuka before being broken up at an unknown date.[3]
