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 ... [...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. 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 ...

Task Force 58
The Fast Carrier Task Force (TF 38 when assigned to Third Fleet, TF 58 when assigned to Fifth Fleet) was a group of ships in World War II. It was the main striking force of the United States Navy in the Pacific War from January 1944 through the end of the war in September 1945. The task force was made up of several separate task groups, each typically built around three to four aircraft carriers and their supporting vessels. The support vessels were screening destroyers, cruisers, and the newly built fast battleships. Carrier-based naval warfare With the arrival of the fleet carriers the primary striking power of the navy was no longer in its battleship force, but with the aircraft that could be brought to battle by the carriers. The means by which the US Navy operated these carriers was developed principally by Admiral Marc Mitscher. Mitscher determined that the best defense for a carrier was its own air groups, and that carriers were more easily defended if they operated t ...

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 ...
