Yūgumo-class destroyer

The Yūgumo-class destroyers (夕雲型駆逐艦, Yūgumo-gata kuchikukan) were a group of 19 destroyers built for the Imperial Japanese Navy during World War II. The IJN called them Destroyer Type-A (甲型駆逐艦,, Kō-gata Kuchikukan) from their plan name. No ships of the class survived the war.

Background

The Yūgumo class was a repeat of the preceding Kagerō class with minor improvements that increased their anti-aircraft capabilities. The first 11 ships of the class were ordered as part of the 1939 4th Naval Armaments Supplement Programme. Another 16 ships (the Hayanami sub-class) were ordered as ships #340 to #355 as part of the 1941 Rapid Naval Armaments Supplement Programme, but of these eight were canceled before being laid down. Another eight ships (the Kai-Yūgumo sub-class) were planned as ships #5041 to #5048 under the 1942 Modified 5th Naval Armaments Supplement Programme, but these were also canceled.[1]

Design and description

The Yūgumo class was 45 tons heavier and a few feet longer than the Kagerō class, distinguishable in silhouette primarily by the shape of the bridge. The Yūgumo class had a forward slope on the bridge, which was intended to reduce wind resistance and improve stability. Another difference was that the Yūgumo-class vessels were built by three different shipyards, and there were minor differences between individual ships, depending on the builder and when the ship was built.[1]

The general specifications for the Yūgumo class was a 119.17-meter (391 ft 0 in) overall length, with a beam of 10.8 meters (35 ft 5 in) and a draft of 3.76 meters (12 ft 4 in).[2] They displaced 2,110 metric tons (2,080 long tons) at standard load and 2,560 metric tons (2,520 long tons) at deep load.[3] Their crew numbered 228 officers and enlisted men.

The ships had two Kampon geared steam turbines, each driving one propeller shaft, using steam provided by three Kampon water-tube boilers. The turbines were rated at a total of 52,000 shaft horsepower (39,000 kW) for a designed speed of 35 knots (65 km/h; 40 mph).[4]

The main battery of the Yūgumo class consisted of six Type 3 127-millimeter (5.0 in) guns in three twin-gun turrets, one superfiring pair aft and one turret forward of the superstructure.[3] The guns were in a new type of mount (known as the "D" mount) which was able to elevate up to 75° to increase their performance against aircraft; however, their slow rate of fire, slow traversing speed, and the lack of any sort of high-angle fire-control system meant that they were virtually useless as anti-aircraft guns.[5] The ships were also armed with eight 610-millimeter (24.0 in) torpedo tubes in a two quadruple traversing mounts; one reload was carried for each tube. Their anti-submarine weapons comprised two depth charge throwers for which 36 depth charges were carried.[3]

As built, the Yūgumo class had four Type 96 25-millimeter (1.0 in) anti-aircraft guns in two twin-mounts forward of the aft smokestack. as with other destroyer classes, as the Pacific War progressed, anti-aircraft armaments were increased. Later, two triple-mount and one twin-mount Type 96 were added forward of the bridge and a Type 22 radar. Units surviving into 1944 had a second triple-mount added on a platform behind the forward smokestack. The six units surviving into 1944 received up to twelve additional single-mount Type 96s and a Type 13 radar. Kiyoshimo also received a number of Type 93 13mm machine guns.[1]

Operational history

The Yūgumo class were considered elite units and always assigned to escort primary fleet units. They were all lost during the Pacific War.
