It was designed to be fast and heavily armed with the lightest displacement possible. However, its normal displacement was 419 tons above the design figures, which affected its speed. During a one-mile run in 1923, it reached a top speed of 34.786 kt with 61,336 hp at 409.87 rpm, but with 75 percent of fuel on board, its draft increased by 61 cm, resulting in a drop in speed below the expected 35.5 kt. \u003c\/blockquote\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFormat\u003c\/strong\u003e: Paperback \/ softback\u003cbr\u003e\u003cstrong\u003eLength\u003c\/strong\u003e: 80 pages\u003cbr\u003e\u003cstrong\u003ePublication date\u003c\/strong\u003e: 28 May 2022\u003cbr\u003e\u003cstrong\u003ePublisher\u003c\/strong\u003e: Kagero Oficyna Wydawnicza\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003eYubari, the smallest of the Japanese cruisers constructed following World War I, was in reality an experimental design. The ship was designed to serve as a testing ground for innovative technologies that would be used in the construction of the future Furutaka-class heavy cruisers. The ship's principal designer, Fujimoto Kikuo, worked under the direction of the Imperial Navy's chief naval architect, Hiraga Yuzuru, to design a swift and heavily armed cruiser with the lightest displacement feasible. What resulted was a vessel capable of matching the speed, range, and broadside weight of 5,500-ton ships, but with a significantly lower displacement. The cruiser's construction was initially authorized under the 1917 8-4 Fleet Program, but funding was not available until the launch of the 1921 8-6 Fleet Program, where the ship was listed under the name Ayase. The blueprints were formally approved in October 1921, and on December 23, 1921, the ship was renamed Yubari, a reference to the Yubarigawa River in Hokkaido. Sea trials of the cruiser confirmed her expected sea-keeping characteristics, but also revealed that she was overweight, a common feature in Japanese designs. After her completion, Yubari's normal displacement (with a 25 percent fuel reserve) was 419 tons (14 percent) above the design figures, which had a detrimental effect on her speed. During a one-mile run conducted on July 5, 1923, Yubari (displacing 3,463 tons) reached a top speed of 34.786 kt with the machinery producing 61,336 hp at 409.87 rpm. With 75 percent of fuel on board, the cruiser's draft increased by 61 cm, which increased drag and resulted in a drop in speed below the expected 35.5 kt.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e: 370g\u003cbr\u003e\u003cstrong\u003eDimension\u003c\/strong\u003e: 299 x 207 x 13 (mm)\u003cbr\u003e\u003cstrong\u003eISBN-13\u003c\/strong\u003e: 9788366673908\u003c\/p\u003e","brand":"Aliaksandr Sukhanevich","offers":[{"title":"Paperback \/ softback","offer_id":44095252529402,"sku":"9788366673908","price":17.84,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0522\/4297\/2845\/products\/1660932036773_book.jpg?v=1661253870","url":"https:\/\/shulphink.com\/products\/the-japanese-light-cruiser-yubari-9788366673908","provider":"Shulph Ink","version":"1.0","type":"link"}
