Wakatake-class Destroyer

The were a class of eight second-class destroyers of the Imperial Japanese Navy.

Background

The medium-sized ''Wakatake''-class destroyers were a follow-on to the as part of the Imperial Japanese Navy's 8-6 Fleet Program from fiscal 1921 as a lower cost accompaniment to the larger s. The class was originally planned to consist of thirteen vessels, but due to the Washington Naval Treaty, as well as budgetary limitations, the orders for the last four were cancelled in 1922, with the final number being reduced to eight when ''No.14'' was also cancelled. The ''Wakatake'' class was the last class to be rated "second class" and all future destroyers were designed larger. It was planned that the ''Wakatake''-class ships should have names, but upon completion they were given numbers. This proved to be extremely unpopular with the crews and was a constant source of confusion in communications, so in 1928, names were assigned.

Design

The ''Wakatake''-class destroyers were essentially slightly modified ''Momi''-class ships with 50 tons additional displacement and a deeper draft to improve handling characteristics in heavy seas, particularly against rolling. Weaponry layout (with the exception of added AA armaments), general arrangement and silhouette were all identical with the ''Momi'' class.

As with the ''Momi'' class, a number of types of steam turbines were used for propulsion. ''Asagao'' was built with Parsons impulse turbines, ''Yūgao'' with Escher Wyss & Cie Zoelly turbines, and the remaining vessels with Brown-Curtis turbines.

The armament for the ''Wakatake''-class was identical to that of the ''Momi'' class. The main battery consisted of three Type 3 120 mm 45 caliber naval guns in single mounts, with two twin Type 6 torpedo launchers. Anti-aircraft protection was provided by two 7.7mm machine guns. After the start of the Pacific War, one of the Type 3 guns was replaced by two triple-mount Type 96 25-mm cannons, although some vessels had three twin-mounts and two single-mounts instead. The minesweeping gear was replaced by 36 to 48 depth charges with four launchers. Some of the vessels also were fitted with a Type 13 radar.

Operational history

The small displacement of the ''Wakatake''-class limited their utility as fleet escorts, and as with the ''Momi''-class, they were mainly used in Chinese coastal waters, where their shallow draft made them suitable for operations in rivers and coastal waters.

On 15 September 1932, capsized due to poor stability and sank north of Keelung near Taiwan. In April 1940 was re-rated as ''Patrol Boat No. 46'', with considerably reduced armament and the removal of one boiler, which reduced her speed to only 18 knots.

Of the remaining six units, three (''Wakatake'', ''Kuretake'', and ''Sanae'') were assigned to Destroyer Division 13 under the Kure Naval District, and patrolled the Seto Inland Sea and the Bungo Strait on antisubmarine patrols. The other three (''Asagao'', ''Fuyō'' and ''Karukaya'') were assigned to Destroyer Division 32 under the Chinkai Guard District, which was assigned to patrol the Tsushima Strait screening maritime traffic in the Tsushima Straits. From 10 April 1942, the 1st Surface Escort Division of the Southwest Area Fleet was created, and Desdivs 13 and 32 were assigned to it to provide protection for convoys against Allied submarine activity. The convoy routes were initially those between Moji, Taiwan, and the Philippines. Later, these routes extended to Singapore, French Indochina, the Netherlands East Indies, and Palau. In the course of this service, set a record by successfully completing 54 convoy escorts before her loss. Of the six destroyers, four were lost to American submarines, and one to an air attack. Only survived the war and was finally broken up in 1948.Nevitt, Combined Fleet.com

List of Ships

The five cancelled units were initially to be named ''Shian'' (from Kawasaki, Kobe)(later ''No.14''), ''Omodaka'' (also from Kawasaki, Kobe)(later ''No.20''), ''Nadeshiko'' (from Fujinagata Zosensho, Osaka)(later ''No.22''), ''Botan'' (from Uraga Dock Co, Tokyo)(later ''No.24'') and ''Basho'' (from Ishikawajima Zosensho, Tokyo)(later ''No.26'').

Naming history

The IJN originally planned that the ''Wakatake''-class ships should have names, but upon completion they were given numbers due to the projected large number of warships the IJN expected to build through the Eight-eight fleet plan. This proved to be extremely unpopular with the crews and was a constant source of confusion in communications. In August 1928, names were assigned, but not the original names that were planned.
