ÅŒtori-class Torpedo Boat
The were a class of eight fast torpedo boats of the Imperial Japanese Navy built before and operated during World War II. Development To circumvent the terms of the 1930 London Naval Treaty, which limited its total destroyer tonnage the Imperial Japanese Navy designed the torpedo boat, but planned to arm it with half the armament of a destroyer. The resultant design was top-heavy and unstable, resulting in the 1934 ''Tomozuru'' Incident, in which one of the ''Chidori''-class vessels capsized. The subsequent investigation revealed the fundamental design flaw, and the four vessels in the class which had been completed were extensively rebuilt, and the remaining sixteen vessels projected were cancelled in favor of a new design which would address these design issues from the beginning. Sixteen ''ÅŒtori''-class vessels were ordered in the 1934 2nd Naval Armaments Supplement Programme, of which eight were completed between 1936 and 1937. The remaining eight were cancelled in favo ...

Torpedo Boat
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes. These were inshore craft created to counter both the threat of battleships and other slow and heavily armed ships by using speed, agility, and powerful torpedoes, and the overwhelming expense of building a like number of capital ships to counter an enemy. A swarm of expendable torpedo boats attacking en masse could overwhelm a larger ship's ability to fight them off using its large but cumbersome guns. A fleet of torpedo boats could pose a similar threat to an adversary's capital ships, albeit only in the coastal areas to which their small size and limited fuel load restricted them. The introduction of fast torpedo boats in the late 19th century was a serious concern to the era's naval strategists, i ...

12 Cm/45 3rd Year Type Naval Gun
12 cm/45 3rd Year Type naval gun was a Japanese naval gun and coast defense gun used on destroyers, and torpedo boats of the Imperial Japanese Navy during World War II. Design and development The 12 cm/45 gun designed in 1895 was an indigenous variant of an Elswick Ordnance Company export design known as the Pattern Y. The Japanese designation was the "Type 41". Later in 1921 the 12 cm/45 gun was used as the basis for a high-angle anti-aircraft gun, designated the 12 cm/45 10th Year Type. The "Third Year Type" refers to the Welin breech block used and this should not be confused with the later Type 3 12 cm AA Gun developed by the Imperial Japanese Army in 1943. In the Japanese Army artillery naming system, "Type 3" refers to the year of introduction, rather than the type of breech block used. When used in naval applications, it was mounted in a shielded barbette, as shown. A redesign in 1922 called the 12 cm 11th Year Type naval gun (Model 1922) with a shorter g ...

Mitsui Engineering & Shipbuilding
() is a Japanese heavy industries company. Despite its name, it no longer builds ships and now focuses mainly on production of high-value ship equipment such as Marine propulsion, engines and automated gantry cranes. Mitsui E&S is the largest supplier of gantry cranes in Japan with a market share of nearly 90 per cent, and its products are used at major ports such as Port of Long Beach, Long Beach, Port of Los Angeles, Los Angeles, Port of Mombasa, Mombasa, Saigon Port, Ho Chi Minh, and Port Klang, Klang. History Mitsui E&S was established in 1917 as the Shipbuilding Division of Mitsui & Co. with the first shipyard at Tamano, Okayama, Tamano. It built the first Japan-built diesel-propelled merchant ship, ''Akagisan Maru'' (:ja:赤城山丸, 赤城山丸) in 1924. With its success, it began manufacturing diesel engines under a license agreement with Burmeister & Wain in Denmark. In 1937, the shipyards became a separate entity within the Mitsui zaibatsu, Tama Shipyard. The com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Hitachi Zosen Corporation
, formerly , is a major Japanese industrial and engineering corporation. It produces waste treatment plants, industrial plants, precision machinery, industrial machinery, steel mill process equipment, steel structures, construction machinery, tunnel boring machines, and power plants. Despite its former name, Hitachi Zosen, of which the last word literally means shipbuilding, no longer builds ships, having spun off the business to Universal Shipbuilding Corporation in 2002, nor is it a '' keiretsu'' company of Hitachi any longer. Reflecting this, the company changed its name to Kanadevia in October 2024. History Kanadevia's origins go back to April 1, 1881, when British entrepreneur Edward H. Hunter established in Osaka to develop the Japanese steel-making and shipbuilding industry. Hunter had come to Japan in 1865 and had established the Onohama Shipyard in Kobe before moving to Osaka and establishing a new shipyard at the junction of the Nakatsu and Aki rivers which coul ...
