Ōtori-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 ''Ōtori''-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 favor o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chidori-class Torpedo Boat
The was an Imperial Japanese Navy class of torpedo boats that were built before and served during the Second World War. The design initially proved to have too much armament for its small displacement, and the capsizing of shortly after completion in heavy weather resulted in a scandal which called into question the basic design of many Japanese warships of the time. After extensive modification, the class became satisfactory sea-boats and saw service in the Battle of the Philippines and the Dutch East Indies campaign as escorts and continued in that role for the rest of the war. Three were sunk during the war and the fourth was seized by the British at Hong Kong after the end of the war, where it was scrapped later. Background Per the terms of the 1930 London Naval Treaty, the Imperial Japanese Navy was constricted on the total tonnage of destroyers it was allowed to construct. In response, Japanese naval planners designed a 600-ton class vessel (which was small enough not to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. A re-design in 1922 called the 12 cm 11th Year Type naval gun (Model 1922) with a shorter gun barrel and a horizontal sliding breech-block was used on submarines and torpe ...

Maizuru Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy. History The Maizuru Naval District was established at Maizuru, Kyoto Prefecture in 1889, as the fourth of the naval districts responsible for the defense of the Japanese home islands. After the establishment of the navy base, a ship repair facility was established in 1901 with a dry dock. With the addition of equipment and facilities for ship production by 1903, the Maizuru Naval Arsenal was officially established. Additional dry docks were completed in 1904 and 1914. When the No. 3 dry dock was completed in 1914, it was the largest in Japan at the time. In 1923, after the Washington Naval Treaty, there were discussions within the Navy Ministry about closing the facility, and it was largely mothballed until 1936. Afterwards, it reopened and expanded, building ships, aircraft and weapons for the military. It specialized mostly in destroyer-size and smaller vessels. Post WW II In the pos ...
