Island-hopping
Leapfrogging, also known as island hopping, was a military strategy employed by the Allies in the Pacific War against the Empire of Japan during World War II. The key idea is to bypass heavily fortified enemy islands instead of trying to capture every island in sequence en route to a final target. The reasoning is that those islands can simply be cut off from their supply chains (leading to their eventual capitulation) rather than needing to be overwhelmed by superior force, thus speeding up progress and reducing losses of troops and materiel. Background By the late 19th century, the U.S. had several interests in the western Pacific to defend; namely, access to the Chinese market, and its colonies – the Philippines and Guam – which the U.S. had gained as a result of the Spanish–American War (1898). After Japan's victories in the Sino-Japanese War (1894–95) and the Russo-Japanese War of 1904, the U.S. began to regard Japan as a potential threat to its interests ...

Earl Hancock Ellis
Lieutenant Colonel Earl Hancock "Pete" Ellis (December 19, 1880 – May 12, 1923) was a United States Marine Corps Intelligence Officer, and author of , which became the basis for the American campaign of amphibious assault that defeated the Japanese in World War II. During World War I, Ellis established his reputation as a superior administrator and trainer when he played a large role in the creation of Marine Corps Base Quantico and operation of the Marine Corps' first Officer Candidate School. He also earned accolades for his work as an organizer when he served as one of the lead staff officers responsible for planning the St. Mihiel and Meuse-Argonne Offensives. Ellis was an alcoholic, and frequently alternated between bouts of excessive drinking and hospitalization to receive treatment for the illnesses and complications it caused. In 1922 and 1923, he carried out a covert spying mission to obtain information on Japanese activities on the islands of the Pacific Ocean. ...

Pacific War
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War. The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more widely accepted that the Pacific War itself began on 7 December (8 December Japanese time) 1941, when the Japanese simultaneously invaded Thailand, attacked the British colonies of Malaya, Singapore, and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island, Guam, and the Philippines. The Pacific War saw the Allies pitted against Japan, the latter ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War Plan Orange
War Plan Orange (commonly known as Plan Orange or just Orange) is a series of United States Joint Chiefs of Staff, Joint Army and Navy Board war plans for dealing with a possible war with Empire of Japan, Japan during the interwar years, years between the First and Second World Wars. It failed to foresee the significance of the technological changes to naval warfare, including the submarine, air support and aircraft carriers, and although the Battle of Midway was important, and the US Navy did "Leapfrogging (strategy), island-hop" to regain lost territory, there was no culminating "showdown" battle as anticipated by Plan Orange. Development Informal studies as early as 1906 covered a number of possibilities, from basing at Gibraltar or Singapore in the Straits Settlements, Singapore (an idea revived by the British before World War II) to "a quick trans-Atlantic dash" to the Pacific.Holwitt, p.131. The plan eventually adopted was conceived by Rear Admiral Raymond P. Rodgers in 1911 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Japanese Imperial Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery.

The Great Pacific War
''The Great Pacific War'' was a 1925 novel by British author Hector Charles Bywater which discussed a hypothetical future war between Japan and the United States. The novel accurately predicted a number of details about the Pacific Campaign of World War II. Bywater was a naval correspondent for the ''London Daily Telegraph''. Plot In ''The Great Pacific War'', the war begins with a Japanese invasion of Manchuria, Formosa and Korea. Japan then stages a surprise attack which results in the nearly complete destruction of the Panama Canal, by exploding a freighter full of explosives in the Gaillard Cut. Legacy In ''Infamy: Pearl Harbor and Its Aftermath'', John Toland states that Isoroku Yamamoto was in the US in 1925 and might have read the New York newspapers' reviews of "The Great Pacific War," which was translated into Japanese and read by senior officers of the Japanese Imperial Navy.William H.

The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Marshall Islands
The Marshall Islands ( mh, Ṃajeḷ), officially the Republic of the Marshall Islands ( mh, Aolepān Aorōkin Ṃajeḷ),'' () is an independent island country and microstate near the Equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the larger island group of Micronesia. The country's population of 58,413 people (at the 2018 World Bank Census) is spread out over five islands and 29 coral atolls, comprising 1,156 individual islands and islets. The capital and largest city is Majuro. It has the largest portion of its territory composed of water of any sovereign state, at 97.87%. The islands share maritime boundaries with Wake Island to the north, Kiribati to the southeast, Nauru to the south, and Federated States of Micronesia to the west. About 52.3% of Marshall Islanders (27,797 at the 2011 Census) live on Majuro. In 2016, 73.3% of the population were defined as being "urban". The UN also indicates a population d ...

Blockade
A blockade is the act of actively preventing a country or region from receiving or sending out food, supplies, weapons, or communications, and sometimes people, by military force. A blockade differs from an embargo or sanction, which are legal barriers to trade rather than physical barriers. It is also distinct from a siege in that a blockade is usually directed at an entire country or region, rather than a fortress or city and the objective may not always be to conquer the area. While most blockades historically took place at sea, blockades are also used on land to prevent entrance of an area. For example, Armenia is a landlocked country that Turkey and Azerbaijan blockade. Thus, Armenia cannot conduct international trade through those countries, and mainly trades through Georgia. This restricts the country's economic development. A blockading power can seek to cut off all maritime transport from and to the blockaded country; although stopping all land transport to an ...
