Japanese Aircraft Carrier Ryūjō
''Ryūjō'' ( "Prancing Dragon") was a light aircraft carrier built for the Imperial Japanese Navy (IJN) during the early 1930s. Small and lightly built in an attempt to exploit a loophole in the Washington Naval Treaty of 1922, she proved to be top-heavy and only marginally stable and was back in the shipyard for modifications to address those issues within a year of completion. With her stability improved, ''Ryūjō'' returned to service and was employed in operations during the Second Sino-Japanese War. During World War II, she provided air support for operations in the Philippines, Malaya, and the Dutch East Indies, where her aircraft participated in the Second Battle of the Java Sea. During the Indian Ocean raid in April 1942, the carrier attacked British merchant shipping with her guns and aircraft. ''Ryūjō'' next participated in the Battle of Dutch Harbor, the opening battle of the Aleutian Islands campaign, in June 1942. She was sunk by American carrier-based air ...

Japanese Aircraft Carrier Ryūhō
was a light aircraft carrier of the Imperial Japanese Navy. She was converted from the submarine tender , which had been used in the Second Sino-Japanese War. One of the least successful of the light aircraft carrier conversions due to her small size, slow speed and weak construction, during World War II, ''Ryūhō'' was used primarily as an aircraft transport and for training purposes, although she was also involved in a number of combat missions, including the Battle of the Philippine Sea. Background The London Naval Treaty imposed limitations on new construction of major capital warships for the major world powers. The Imperial Japanese Navy responded in part by the construction of auxiliary vessels, such as fleet oilers and submarine tenders, designed so that they could be converted quickly into aircraft carriers in time of conflict. ''Taigei'' was ordered as part of the 1st Naval Armaments Supplement Programme of 1932. Design Although ''Taigei'' was designed from the onse ...

Length Overall
Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often reported. T ...

Background The Japanese planned to occupy islands in the Aleutians in order to extend their defensive perimeter in the North Pacific to make it more difficult for the U.S. to attack Japan from that area. The air raid on Dutch Harbor was conducted to support the invasions on Kiska Island and Attu Island by the Japanese military under Operation AL. Dutch Harbor was ringed with anti-aircraft artillery batteries from the 206th Coast Artillery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dutch East Indies Campaign
The Dutch East Indies campaign of 1941–1942 was the conquest of the Dutch East Indies (present-day Indonesia) by forces of the Empire of Japan in the early days of the Pacific campaign of World War II. Allied forces attempted unsuccessfully to defend the islands. The East Indies were targeted by the Japanese for their rich oil resources which would become a vital asset during the war. The campaign and subsequent three-and-a-half-year Japanese occupation was also a major factor in the end of Dutch colonial rule in the region. Background The East Indies was one of Japan's primary targets if and when it went to war because the colony possessed abundant valuable resources, the most important of which were its rubber plantations and oil fields; the colony was the fourth-largest exporter of oil in the world, behind the U.S., Iran, and Romania. The oil made the islands enormously important to the Japanese, so they sought to secure the supply for themselves. They sent four fleet ca ...
