Japanese Escort Shimushu
was the lead ship of her class of four escort ships built for the Imperial Japanese Navy during World War II. Background and description The Japanese called these ships ''Kaibōkan'', "ocean defence ships", (''Kai'' = sea, ocean, ''Bo'' = defence, ''Kan'' = ship), to denote a multi-purpose vessel. They were initially intended for patrol and fishery protection, minesweeping and as convoy escorts. The ships measured overall, with a beam of and a draft of .Chesneau, p. 205 They displaced at standard load and at deep load. The ships had two diesel engines, each driving one propeller shaft, which were rated at a total of for a speed of . The ships had a range of at a speed of .Jentschura, Jung & Mickel, p. 186 The main armament of the ''Shimushu'' class consisted of three Type 3 guns in single mounts, one superfiring pair aft and one mount forward of the superstructure. They were built with four Type 96 anti-aircraft guns in two twin-gun mounts, but the total was increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

Leyte (island)
Leyte ( ) is an island in the Visayas group of islands in the Philippines. It is eighth-largest and sixth-most populous island in the Philippines, with a total population of 2,626,970 as of 2020 census. Since the accessibility of land has been depleted, Leyte has provided countless number of migrants to Mindanao. Most inhabitants are farmers. Fishing is a supplementary activity. Rice and corn (maize) are the main food crops; cash crops include coconuts, abaca, tobacco, bananas, and sugarcane. There are some manganese deposits, and sandstone and limestone are quarried in the northwest. Politically, the island is divided into two Provinces of the Philippines, provinces: Leyte (province), (Northern) Leyte and Southern Leyte.

Hi Convoys
were a numbered series of World War II trade convoys between Japan and Singapore. Merchant ships from Moji-ku, Kitakyūshū, Moji and Kaibōkan from Sasebo Naval Arsenal, Sasebo formed southbound convoys in Imari, Saga, Imari Bay to carry supplies for the Burma Campaign. Northbound convoys transported food, petroleum, and raw materials to Japan from the captured European colonies of the Dutch East Indies, French Indochina, and British Malaya and British rule in Burma, Burma. These convoys were initiated in mid-1943 to protect fast, high-value Tanker (ship), tankers and troopships from the improved effectiveness of Mark 14 torpedoes carried by United States submarines. Convoy routing was through the East China Sea, Formosa Strait, and South China Sea. Ships often joined or left convoys at the Formosan ports of Kaohsiung, Takao and Keelung, at the Mako Guard District, Mako naval base in the Pescadores, and at the Vietnamese ports of Cape Saint Jacques and Cam Ranh Bay. Some convoys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battlecruiser
The battlecruiser (also written as battle cruiser or battle-cruiser) was a type of capital ship of the first half of the 20th century. These were similar in displacement, armament and cost to battleships, but differed in form and balance of attributes. Battlecruisers typically had thinner armour (to a varying degree) and a somewhat lighter main gun battery than contemporary battleships, installed on a longer hull with much higher engine power in order to attain greater speeds. The first battlecruisers were designed in the United Kingdom, as a development of the armoured cruiser, at the same time as the dreadnought succeeded the pre-dreadnought battleship. The goal of the design was to outrun any ship with similar armament, and chase down any ship with lesser armament; they were intended to hunt down slower, older armoured cruisers and destroy them with heavy gunfire while avoiding combat with the more powerful but slower battleships. However, as more and more battlecruisers were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palembang
Palembang () is the capital city of the Indonesian province of South Sumatra. The city proper covers on both banks of the Musi River on the eastern lowland of southern Sumatra.

Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...

British Malaya
The term "British Malaya" (; ms, Tanah Melayu British) loosely describes a set of states on the Malay Peninsula and the island of Singapore that were brought under British hegemony or control between the late 18th and the mid-20th century. Unlike the term "British India", which excludes the Indian princely states, British Malaya is often used to refer to the Federated and Unfederated Malay States, which were British protectorates with their own local rulers, as well as the Straits Settlements, which were under the sovereignty and direct rule of the British Crown, after a period of control by the East India Company. Before the formation of the Malayan Union in 1946, the territories were not placed under a single unified administration, with the exception of the immediate post-war period when a British military officer became the temporary administrator of Malaya. Instead, British Malaya comprised the Straits Settlements, the Federated Malay States, and the Unfederated Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
55th Division (Imperial Japanese Army)
The was an infantry division of the Imperial Japanese Army during World War II. Its call sign was the . It was formed on 10 July 1940 at Zentsūji, simultaneously with 51st, 52nd, 54th, 56th, and 57th divisions. The formation nucleus was the headquarters of the 11th Division. Its manpower came primarily from the four prefectures of Shikoku Island. The 55th Division was initially assigned to the Central District Army. In 1941, the division was assigned to the 15th Army and participated in the Japanese conquest of Burma. The division had the 143rd Regiment detached to separately capture Dawei (Tavoy) and Myeik (Mergui), while the main troop had captured Mawlamyine (Moulmein) on 31 January 1942. In March 1942 the division fought for 14 days around the city of Taungoo against the weakened Chinese 200th Division. The fight ended when the Chinese broke through and disengaged. On 18 April 1942, the 55th Division had encircled the Chinese 55th Division, eventually wiping it ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

Superfiring
Superfiring armament is a naval military building technique in which two (or more) turrets are located in a line, one behind the other, with the second turret located above ("super") the one in front so that the second turret can fire over the first. This configuration meant that both forward or aft turrets could fire at any target within their sector, even when the target was in the same vertical plane as the turrets. History The history of large surface warships follow generic labels as battleships, and a further distinction between pre-dreadnoughts and dreadnoughts. The era of technical evolution occurred roughly from 1900 to 1945. Part of the technical evolution was driven by the need to compress as much large-gun firepower into the smallest space possible. In early designs, the large-caliber turrets were all located on the same plane firing to one side or the other. In firing ahead or to the rear, usually only the forward-most or rearmost turret could fire, especially a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
