List of active ships of the Japan Maritime Self-Defense Force is a list of ships in active service with the Japan Maritime Self-Defense Force. The JMSDF is one of the world's largest navies and the second largest navy in Asia in terms of fleet tonnage.[1] As of 2016, the JMSDF operates a total of 155 vessels (including minor auxiliary vessels), including; four helicopter destroyers (or helicopter carriers), 26 destroyers, 10 small destroyers (or frigates), six destroyer escorts (or corvettes), 19 attack submarines, 30 mine countermeasure vessels, six patrol vessels, three landing ship tanks, 8 training vessels and a fleet of various auxiliary ships.[2][3]

As of 2013, a procurement list added to the current National Defense Program Guidelines has revealed that, among other things, an additional 48 escort vessels of various classes are planned to be added to the MSDF fleet in the coming decade.[4] In addition, as of 7 July 2013, it was being reported that plans were under way to procure two more Aegis equipped destroyers in order to bolster ongoing BMD efforts, the first to be contracted for in fiscal year 2015 and the other in fiscal year 2016.[5]

Future JMSDF vessels[edit]

  • Asahi-class destroyer (25DD, New 5,000-ton destroyer program first revealed in the MoD's FY2013 budget request, JS Asahi (DD-119)[9] and a second in FY2014, DD-120.[10] Seemingly an ASW optimised development of the Akizuki class likely intended for Sea lines of communication duties rather than the escort of Aegis destroyers as in the case of the Akizuki. Planned to cost even less to operate and maintain than the already low cost Akizuki class, partly through the use of COGLAG [Combined Gas turbine Electric And Gas turbine] propulsion. ¥72.3 billion has been requested for the construction of the first unit in the class, and to respond to a reduction of Hatsuyuki-class destroyers)
  • DDR Destroyer Revolution (5400 tonnes Light Escort Destroyer project, also referred to as 'the next generation escort ship'. Program in existence since 2009, current plans are to start construction on the first of class by 2021 at the latest. Full scale R&D activities scheduled from 2011 onwards.)
  • In 2013 plans for an additional 2-4 AEGIS destroyers was presented. The first pair should be in service by 2018.[11]
  • Also in late 2013, it was being reported that a new high speed small destroyer (frigate) class was to be procured. Full displacement would be in the 3,000-ton range. No other details such as development history were immediately available, though it was implied that the vessels would be optimised for Anti-surface warfare. Peacetime roles would be primarily outer island warning and surveillance. In accordance with current MSDF/MOD practice, these vessels would likely be referred to as escort ships despite their actual role/s.[12]
  • The Japanese government is reported to be considering the procurement of a LCS (corvette) type vessel. In March 2014, Japan and the U.S. agreed to undertake studies concerning joint development between the two countries of a high-speed littoral combat ship. Exact details are unknown, but press reports indicate it may be a trimaran, similar to the Independence-class LCS.[13]
  • In 2014, Japanese Defense Minister Itsunori Onodera expressed the intention of buying one amphibious assault ship from the United States to provide more amphibious capabilities than the current Osumi class landing ships. The Wasp class amphibious assault ship is most likely candidate for acquisition.[14]
  • In August 2015, a new subclass of the Atago-class, dubbed the 27DDG Destroyer, was announced. With an empty displacement of 8,200 tons and utilising COGLAG propulsion, the new class is intended to be equipped with both a laser based point defense system (developed by the Technical Research & Development Institute) and provision to be fitted with a naval railgun also currently under development by Japan. The first two ships of the new class are expected to enter service in 2020 and 2021 respectively.
