Momi Class Destroyer - As Patrol Boats

As Patrol Boats

Beginning in 1939, nine Momi-class vessels were re-classified as patrol boats and converted for escort duty, having one boiler removed (dropping their power to 12,000 ihp (8,900 kW) and speed to just 18 knots (21 mph; 33 km/h). and their torpedo tubes, minesweeping gear, and one gun mount replaced by six Type 96 25 mm AT/AA Guns, 36 depth charges, and depth charge throwers. As well, their names were dropped and they were simply numbered.

During 1941-42, these vessels were modified again, to carry and launch a Toku Daihatsu class landing craft, by having the aft smoke stack removed and the stern modified with a sloping deck to the waterline, as well as providing accommodation for 150 naval infantry troops. All of these vessels except ex-Fuji (as Patrol Boat #36) were sunk during the course of the Pacific War.
