Pagoda Mast
A pagoda mast was a type of superstructure erected on a tripod mast that was common on Japanese capital ships that were reconstructed during the 1930s in a bid to improve their fighting performance. These modifications were deemed to be necessary by the Imperial Japanese Navy as a result of the "Battleships Holiday" that was imposed by the Washington Naval Treaty, which strictly limited the construction of new battleships. Development Pagoda masts were built on existing tripod masts by adding searchlight and other platforms, lookouts and shelters upon each other, the result resembling a pagoda temple. The superstructures were constructed on the majority of the ships that were rebuilt by the Japanese during the 1930s, including the s and the , , and -class battleships. The additional platforms were supported on the ships' original tripod foremasts (a design also extensively used by the Royal Navy), which were suitably strengthened to bear the extra weight. As completed, the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shipbuilding
Shipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. History Pre-history The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia. They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf. 4th millennium BC Ancient Egypt Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC.

World War II Naval Ships Of Japan
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and those of the United States. Over the course of seven hours there were coordinated Japanese attacks on the US-held Philippines, Guam, and Wake Island and on the British Empire ...

Standard-type Battleship
The Standard-type battleship was a series of twelve battleships across five classes ordered for the United States Navy between 1911 and 1916 and commissioned between 1916 and 1923. These were considered super-dreadnoughts, with the ships of the final two classes incorporating many lessons from the Battle of Jutland. Each vessel was produced with a series of progressive innovations, which contributed to the pre–World War I arms race. The twelve vessels constituted the US Navy's main battle line in the interwar period, while many of the ten earlier dreadnoughts were scrapped or relegated to secondary duties. Restrictions under the 1922 Washington Naval Treaty limited total numbers and size of battleships and had required some under construction to be cancelled, so it was not until the onset of World War II that new battleships were constructed. On December 7, 1941, eight were at Pearl Harbor, one at Bremerton, Washington, and three were assigned to the Atlantic Fleet. Doctri ...

Lattice Mast
Lattice masts, or cage masts, or basket masts, are a type of observation mast common on United States Navy major warships in the early 20th century. They are a type of hyperboloid structure, whose weight-saving design was invented by the Russian engineer Vladimir Shukhov. They were used most prominently on American dreadnought battleships and armored cruisers of the World War I era. In the age of sail, masts were required to support the sails, and lookouts were posted on them; with the advent of engine-powered warships, masts were retained and used for observation and to spot fall of shot. The purpose of the lattice structure was to make the posts less vulnerable to shells from enemy ships, and to better absorb the shock caused by firing heavy guns, isolating the delicate fire control equipment (rangefinders, etc.) mounted on the mast tops. However, the masts were found to be easily damaged by the inclement weather experienced at sea by naval ships during typhoons and hurricanes: ...

Nelson-class Battleship
The ''Nelson'' class was a class of two battleships ( and ) of the British Royal Navy, built shortly after, and under the terms of, the Washington Naval Treaty of 1922. They were the only British battleships built between the (ordered in 1913) and the , ordered in 1936. The ships were named after famous British admirals: George Brydges Rodney, 1st Baron Rodney, victor of the Battle of Cape St. Vincent and the Battle of the Saintes, and Horatio Nelson, 1st Viscount Nelson, who won the Battles of the Nile and Trafalgar. To comply with the limitations of the Washington Treaty, these ships were of an unusual design with many novel features. They are often referred to as the first treaty battleships. The ''Nelson''s were unique in British battleship construction, being the only ships to carry a main armament of nine guns. The most unusual feature however, and one that is immediately noticeable, is that these were all carried forward of the bridge. Commissioned in 1927–29, th ...

Christmas Tree
A Christmas tree is a decorated tree, usually an evergreen conifer, such as a spruce, pine or fir, or an artificial tree of similar appearance, associated with the celebration of Christmas. The custom was further developed in early modern Germany where German Protestant Christians brought decorated trees into their homes. It acquired popularity beyond the Lutheran areas of Germany and the Baltic governorates during the second half of the 19th century, at first among the upper classes. The tree was traditionally decorated with "roses made of colored paper, apples, wafers, tinsel, ndsweetmeats". Moravian Christians began to illuminate Christmas trees with candles, which were often replaced by Christmas lights after the advent of electrification. Today, there is a wide variety of traditional and modern ornaments, such as garlands, baubles, tinsel, and candy canes. An angel or star might be placed at the top of the tree to represent the Angel Gabriel or the Star of Bethle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Architecture
Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation of marine vessels and structures. Naval architecture involves basic and applied research, design, development, design evaluation (classification) and calculations during all stages of the life of a marine vehicle. Preliminary design of the vessel, its detailed design, construction, trials, operation and maintenance, launching and dry-docking are the main activities involved. Ship design calculations are also required for ships being modified (by means of conversion, rebuilding, modernization, or repair). Naval architecture also involves formulation of safety regulations and damage-control rules and the approval and certification of ship designs to meet statutory and non-statutory requirements. Main subjects The word "vessel" in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
