In the Murasame class, the hull design was completely renovated from first-generation destroyers. In addition to increasing the size in order to reduce the underwater radiation noise, both the superstructure and hull were inclined to reduce

36-550: A unique long forecastle style called "Oranda-zaka". The engine arrangement is COGAG , same as in the Asagiri class, but a pair of engines were updated to Spey SM1Cs , and the remaining pair were replaced by LM2500s , as used in the Kongō class. Samidare was laid down on 11 September 1997, by Ishikawajima Harima Heavy Industries at Tokyo as part of the 1995 plan and launched on 24 September 1998. Commissioned on 21 March 2000,

54-623: Is to operate helicopters . It has a large flight deck that occupies a substantial part of the deck, which can extend the full length of the ship like HMS  Ocean of the Royal Navy (RN), or extend only partway, usually aft, as in the Soviet Navy 's Moskva class or in the Chinese Navy 's Type 0891A . It often also has a hangar deck for the storage and maintenance of rotorwing aircraft. Pure helicopter carriers are difficult to define in

72-451: The Wasp class, are also capable of embarking troops such as marines and landing them ashore; they are classified as amphibious assault ships . Helicopter carriers have been used as anti-submarine warfare carriers and amphibious assault ships. HMS  Hermes and two of her sisters were 22,000 ton fleet carriers converted to "commando carriers" only able to operate helicopters. Hermes

90-591: The radar cross-section . However, there is no angled tripod mainmast as on American Arleigh Burke -class destroyers because of the heavy weather of the Sea of Japan in winter. The aft was designed like a "mini- Oranda-zaka " as with the Kongō class to avoid interference between helicopters and mooring devices. Destroyers built under the First Defense Build-up Plan, including the former Murasame class , adopted

108-730: The 21st century. The advent of STOVL aircraft such as the Harrier jump jet , and now the F-35 , have complicated the classification; the United States Navy 's Wasp class , for instance, carries six to eight Harriers as well as over 20 helicopters. Only smaller carriers unable to operate the Harrier, and older, pre-Harrier-era carriers, can be regarded as true helicopter carriers. In many cases, other carriers, able to operate STOVL aircraft, are classified as " light aircraft carriers ". Other vessels, such as

126-533: The JMSDF started construction of general-purpose destroyers ( 汎用護衛艦 , Hanyou-goei-kan ) under the eight ships / eight helicopters concept. In this concept, each flotillas would be composed of one helicopter destroyer (DDH) , five general-purpose destroyers (DD), and two guided-missile destroyers (DDG). By FY1986, construction of twenty first-generation DDs (twelve Hatsuyuki class and eight Asagiri class ) required for all four flotillas had been completed. In

144-541: The NOLQ-3 electronic warfare suite and OQS-5 bow-mounted sonar. To enhance the low-observability and combat readiness capability, vertical launching systems were adopted on its missile systems: Mk 41 for VL-ASROC and Mk 48 for Sea Sparrow replace the traditional swivel octuple launchers. And the surface-to-surface missile system is alternated by the SSM-1B of Japanese make. Currently, ships of this class have been switching

162-549: The class are named after Imperial Japanese Navy destroyers in World War II. The hull design was completely renovated from first-generation DDs. In addition to increasing the size in order to reduce the underwater radiation noise, both superstructure and hull were inclined to reduce the radar cross-section . There is however no angled tripod mainmast like the one of the American Arleigh Burke -class destroyer because of

180-428: The equipment is the same as first-generation DDs, but they are updated and enhanced throughout. Concepts of its combat system were partly based on those of Kongō class. Two large-screen displays and OJ-663 consoles are introduced in its OYQ-9 combat direction system as Aegis Weapon System (AWS) . And OYQ-103 ASW combat systems, based on OYQ-102 of Kongō class and indirectly AN/SQQ-89 , present an integrated picture of

198-414: The heavy weather of the Sea of Japan in winter. The aft was designed like a "mini- Oranda-zaka " as with the Kongō class to avoid interference between helicopters and mooring devices. The engine arrangement is COGAG as same as Asagiri class, but a pair of engines are updated to Spey SM1C . And the remaining one pair are replaced by LM2500 , same as Kongō class. The basic configuration of

216-434: The original plan, it was supposed to shift to destroyer escorts for local District Forces afterwards. However, if the use of these first-generation DDs was continued to the full extent of ships' life, the relative performance obsolescence was concerned. Thus the JMSDF decided to advance the construction of the new generation DDs. And this was the first class of the second-generation DDs. Except for Kirisame , all ships of

234-472: The point defense missile system from the traditional Sea Sparrow (RIM-7M) to the Evolved Sea Sparrow by FY2012. The aircraft facility is expanded to accommodate two shipboard helicopters . One Mitsubishi SH-60J/K is a basic load, and another can be accommodated in case of overseas operation. Helicopter carrier A helicopter carrier is a type of aircraft carrier whose primary purpose

252-637: The same year, Samidare conducted communication training using radio with the Chinese Navy destroyer Taiyun (which was scheduled to participate in the JMSDF Fleet review on 14 October, but canceled due to Typhoon Hagibis ) in the Pacific Ocean south of Kanto region. This was the third Japan-China goodwill training for the JMSDF, the previous being in December 2011. On 4 May 2022, Samidare deployed to Djibouti for anti-piracy operations. In late May, Samidare
