Asahi-class Destroyer
The ''Asahi'' class of destroyers of the Japan Maritime Self-Defense Force is optimized for undersea warfare. The class was initially designated "25DD", referring to a date on the Japanese calendar, specifically the 25th fiscal year of the Heisei period (2013). The lead ship, ''Asahi'', is the third ship to hold the name after the ''Asahi''-class destroyer escort lent from the United States Navy in 1955, and the Imperial Japanese battleship. The second ship of the class, ''Shiranui'', is the third ship to hold the name after the ''Murakumo'' and ''Kagerō''-class destroyers. Development The procurement of the destroyer began in 2013 in response to the reduction in the number of destroyers (namely the ) within the JMSDF. The two major characteristics of this destroyer is its bigger emphasis on anti-submarine warfare and the adoption of the COGLAG (combined gas turbine electric and gas turbine: a modification of the combined gas and gas propulsion system employing electri ...

RIM-162 ESSM
The RIM-162 Evolved SeaSparrow Missile (ESSM) is a development of the RIM-7 Sea Sparrow missile used to protect ships from attacking missiles and aircraft. ESSM is designed to counter supersonic maneuvering anti-ship missiles. ESSM also has the ability to be "quad-packed" in the Mark 41 Vertical Launch System, allowing up to four ESSMs to be carried in a single cell. Design The original Sea Sparrow was an expedient design intended to provide short-range defensive fire in a system that could be deployed as rapidly as possible. The AIM-7 Sparrow was the simplest solution as its radar guidance allowed it to be fired head-on at targets and this guidance was easily provided by mounting an aircraft radar on a trainable platform. In the years after its introduction, it was upgraded to follow improvements being made in the air-to-air Sparrow models used by the US Navy and US Air Force. The ultimate version in this line of weapons was the R model, which introduced a new dual-seeker homing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Destroyer Shiranui (1938)
was the second vessel to be commissioned in the 19-vessel destroyers built for the Imperial Japanese Navy in the late 1930s under the Circle Three Supplementary Naval Expansion Program (''Maru San Keikaku''). Background The ''Kagerō''-class destroyers were outwardly almost identical to the preceding light cruiser-sized , with improvements made by Japanese naval architects to improve stability and to take advantage of Japan’s lead in torpedo technology. They were designed to accompany the Japanese main striking force and in both day and night attacks against the United States Navy as it advanced across the Pacific Ocean, according to Japanese naval strategic projections. Despite being one of the most powerful classes of destroyers in the world at the time of their completion, only one survived the Pacific War. ''Shiranui'', built at the Uraga Dock Company, was laid down on 30 August 1937, launched on 28 June 1938 and commissioned on 20 December 1939. Operational histor ...

Murakumo-class Destroyer
The ("Gathering Clouds") were a class of six torpedo boat destroyers (TBDs) of the Imperial Japanese Navy, built in Britain in 1897–99. The class is also sometimes referred to as the ("Daybreak"). All were named after celestial phenomena. Background In the First Sino-Japanese War, the Japanese navy came to understand the combat effectiveness of small, fast torpedo equipped warships over larger, slower ships equipped with slow-loading and often inaccurate naval artillery. The ''Murakumo''-class vessels were the first class of destroyers to be procured by the Imperial Japanese Navy, but were purchased almost simultaneously with the , whose lead ship ''Ikazuchi'' was the first to be laid down and launched. Four ships were ordered under the 1896 fiscal year budget (''Murakumo'' and ''Shinonome'' on 15 January 1897, and ''Yūgiri'' and ''Shiranui'' on 7 May), and an additional two under the 1897 budget (''Kagerō'' and ''Usugumo'' on 6 May 1898). All were ordered from John I. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Battleship Asahi
was a pre-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the late 1890s. As Japan lacked the industrial capacity to build such warships itself, the ship was designed and built in the United Kingdom. Shortly after her arrival in Japan, she became flagship of the Standing Fleet, the IJN's primary combat fleet. She participated in every major naval battle of the Russo-Japanese War of 1904–1905 and was lightly damaged during the Battle of the Yellow Sea and the Battle of Tsushima. ''Asahi'' saw no combat during World War I, although the ship participated in the Siberian Intervention in 1918. Reclassified as a coastal defence ship in 1921, ''Asahi'' was disarmed two years later to meet the terms of the Washington Naval Treaty, after which she served as a training and submarine depot ship. She was modified into a submarine salvage and rescue ship before being placed in reserve in 1928. ''Asahi'' was recommissioned in late 1937, after the start of the Second ...

USS Amick
USS ''Amick'' (DE-168) was a built for the United States Navy during World War II. She served in the Atlantic Ocean and then the Pacific Ocean and provided escort service against submarine and air attack for Navy vessels and convoys. She was laid down on 30 November 1942 by the Federal Shipbuilding & Drydock Co., Newark, New Jersey; launched on 27 May 1943; sponsored by Mrs. Mary R. Amick, widow of Ens.

Heisei Period
The is the period of Japanese history corresponding to the reign of Emperor Emeritus Akihito from 8 January 1989 until his abdication on 30 April 2019. The Heisei era started on 8 January 1989, the day after the death of the Emperor Hirohito, when his son, Akihito, acceded to the throne as the 125th Emperor. In accordance with Japanese customs, Hirohito was posthumously renamed "Emperor Shōwa" on 31 January 1989. Thus, 1989 corresponds to Shōwa 64 until 7 January, and from 8 January. The Heisei era ended on 30 April 2019 (Heisei 31), with the abdication of Akihito from the Chrysanthemum Throne.

Japanese Calendar
Japanese calendar types have included a range of official and unofficial systems. At present, Japan uses the Gregorian calendar together with year designations stating the year of the reign of the current Emperor. The written form starts with the year, then the month and finally the day, coinciding with the ISO 8601 standard. For example, February 16, 2003 can be written as either 2003年2月16日 or 平成15年2月16日 (the latter following the regnal year system). 年 reads ''nen'' and means "year", 月 reads ''gatsu'' or 「がつ」and means "month" and finally 日 (usually) reads ''nichi'' (its pronunciation depends on the number that precedes it, see below) and means "day". Prior to the introduction of the Gregorian calendar in 1873, the reference calendar was based on the lunisolar Chinese calendar. History The lunisolar Chinese calendar was introduced to Japan via Korea in the middle of the sixth century. After that, Japan calculated its calendar using various Chine ...

Japan Maritime Self-Defense Force
, abbreviated , also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships, 346 aircraft and 50,800 personnel. History Origin Following Japan's defeat in World War II, the Imperial Japanese Navy was dissolved by the Potsdam Declaration acceptance. Ships were disarmed, and some of them, such as the battleship , were taken by the Allied Powers as reparation. The remaining ships were used for repatriation of the Japanese soldiers from abroad and also for minesweeping in the area around Japan, initially under the control of the ''Second Bureau of the Demobilization Ministry''. The minesweeping fleet was eventually transferred to the newly formed Maritime Safety Agency, which helped maintain the resources and expertise of the navy. Japan's 1947 Constitution w ...

Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
