DE Abukuma Class

The Abakuma class escort ship was planned for missions such as antisubmarine patrol operations and attack of surface vessels in the coast sea area. Specific improvements include improved characteristics and improvement of habitability. The hull form is inclined to "V" shape in order to make the radar cross section decrease at an inclination to the side. However, the upper areas are like the former escort ships, which probably means that the stealth characteristics are limited. If the anti-aircraft missile and the helicopter are excluded, it is a match to other escort ships, since for the first time it has the air search radar on a DE type ship.

In 1991, the 3rd and 4th ship of 'Abukuma' type DE vessel 'Oyodo' and 'Sendai' were constructed at Mitsui Engineering and Shipbuilding CO., Ltd (MES) and Sumitomo Heavy Industries, Ltd.(SHI). The propulsion system was CODOG type with each two of Spey gas turbine and diesel engine. The gas turbines were manufactured by KHI, the diesel engines by Mitsubishi Heavy Industries, Ltd. (MHI).

As to the MIA gas turbine Auxiliary Generating Engine which was originally developed by KHI, one set of MIA-02 type gas turbine (1,000kW) is installed on each "Hatsuyuki" type DD vessel (total 12 ships), two sets are installed on each "Asagiri" type DD vessel (total 8 ships), and one set is installed on each "Abukuma" type DE vessel (total 6 ships).


Jintsu, a 5595-ton Sendai class light cruiser, was built at Kobe, Japan. She was completed at the end of July 1925 and for the next three years mainly served with other light cruisers. Soon after the commencement of the Pacific War in December 1941, Jintsu and her destroyers took part in the invasion of the southern Philippines. On 12-13 July 1943, while escorting destroyer transports taking troops to Vila, on Kolombangara, she encountered a superior force of Allied cruisers and destroyers. Hit hard by gunfire from the cruisers USS Honolulu, USS St. Louis and HMNZS Leander, and by a destroyer's torpedo, Jintsu broke in two amidships and sank with the loss of nearly 500 of her crew.
