Japan’s Maritime Self-Defense Force (JMSDF)

 

The Japan’s Maritime Self-Defense Force is a well-equipped and modern military navy. The the Chief of the Maritime Staff is Katsutoshi Kawano. Its structure consists of five regional district commands:

District Tasks

In each district, it is located a major JMSDF base, and contains one or two regional escort squadrons, composed of two to three destroyers or destroyer escorts (DE). These destroyers are not the newest ones and tend to be of older classes, mainly former escort force ships. The destroyer escorts, on the other hand, tend to be purpose built vessels.

The Self-Defense Fleet, headquartered at Yokosuka, consists of the JMSDF’s military shipping. It is composed of four Escort Flotillas (based in Yokosuka, Sasebo, Maizuru, Ominato and Kure), the Fleet Air Force headquartered at Atsugi, two Submarine Flotillas based at Kure and Yokosuka.

The composition of forces in each escort flotilla has some reminiscences of the old style in the Japanese Imperial Navy. At that time, the fleet was composed by 8 battleships and 8 cruisers. Now they have similar structure as an 8-8 fleet of 8 DD and 8 on-board helicopters.

In addition, in each force the 8 DD are distributed as follows: one helicopter destroyer (DDH) acting as a command ship, two guided-missile destroyers (DDG) and 5 standard or ASW destroyers (DD). Future plans include the reorganization of the Escort Flotillas into a DDH group and DDG group, enabling faster overseas deployments.

As of 2014, the JMSDF operates a total of 124 ships (excluding minor auxiliary vessels), including:

 

  • 4 helicopter carriers DDH (called helicopter destroyers)
  • 26 destroyers DD
  • 11 small destroyers FDD (or frigates)
  • 6 destroyer escorts DE (or corvettes)
  • 16 attack submarines
  • 29 mine countermeasure vessels
  • 6 patrol vessels
  • 3 landing ship tanks
  • 8 training vessels.

The fleet has a total displacement of approximately 450,000 tonnes (including auxiliary vessels).

On the other hand, this fleet is supported  a naval aviation that maintains a large naval air force,  including 201 fixed-wing aircraft and 145 helicopters. Most of these aircraft are used in anti-submarine warfare operations.
