Shiranui (DD-120) is a modern Japanese destroyer, the keel of which was laid in May 2016, launched in October 2017, and commissioned in February 2019. The total length of the ship is 151 meters and 18.3 meters wide. Full displacement is about 6,800 tons, and the maximum speed is around 30 knots. The destroyer is armed with: a single 127 mm Mark 45 cannon, 8 single Type 90 anti-ship missile launchers, a single 32-rail VLS Mk. 41 or two 20mm Vulcan Phalanx Block 1B sets. The ship can also take on board a single SH-60 helicopter.
Shiranui (DD-120) is the second-highest Asahi-class destroyer. Design work on destroyers of this type started in 2013, and their main goal was: on the one hand, to supplement the Akizuki-class units in the JMSDF teams, and on the other - to complete replacement of the Hatsuyuki-class ships, which began entering service at the beginning of the years 80s of the twentieth century. When designing Asahi-class destroyers, particular emphasis was placed on the ZOP (anti-submarine) capabilities, and efforts were made to provide them with the greatest possible modernization potential. They also received very modern radar equipment - including GaN-AESA class radars, i.e. radars with active electronic scanning based on gallium nitride technology. It is worth adding that these are the first destroyers in the JMSDF that use a COGLAG power plant, i.e. a power plant "composed" of gas turbines and an advanced electric drive. As a result, they are characterized by low fuel consumption, and thus achieve a good cruising range without refueling at sea. Shiranui (DD-120) was built at the Mitsubishi Heavy Industries shipyard in Nagasaki and its home base is Ominato. Shiranui (DD-120) has the same name as the two Japanese destroyers from the late 19th century and the Second World War.
