I-512L Advance Parole Authorization For DACA Recipient (2014)
, previously ''Project S22'' and ''Submarine No. 44'', was a submarine in commission in the Imperial Japanese Navy from 1924 to 1938. Although not a successful design, she was the lead vessel and prototype of the Japanese s which served in World War II. The Japanese also used her for early experiments in the development of submarine aircraft carriers. Background Following World War I, the Imperial Japanese Navy General Staff began to re-consider submarine warfare as an element of fleet strategy. Before the war, the Imperial Japanese Navy regarded submarines as useful only for short-range coastal point defense. However, based on the success of the Imperial German Navy in deploying long-range cruiser submarines for commerce raiding during World War I, Japanese strategists came to realize the potential for using submarines for long-range reconnaissance, as well as in a war of attrition against an enemy fleet approaching Japan.Peattie, Evans, ''Kaigun'', p.114, 212-214 Procurement of a ...

Kure Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy. History The Kure Naval District was established at Kure, Hiroshima in 1889, as the second of the naval districts responsible for the defense of the Japanese home islands. Along with the establishment of the navy base, a ship repair facility was also constructed, initially by moving the equipment from the Onohama shipyards near Kobe. Construction was supervised by the French engineer Louis-Émile Bertin. The first warship constructed at Kure, '' Miyako'', was launched in 1897. The "Kure Shipyards" were officially renamed the "Kure Naval Arsenal" in 1903. Kure developed into one of the largest shipbuilding facilities in the Empire of Japan, capable of working with the largest vessels. The Arsenal included a major steel works (built with British assistance), and also facilities for producing naval artillery and projectiles. The battleships ''Yamato'' and '' Nagato'' were designed and con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Vessel
The lead ship, name ship, or class leader is the first of a series or class of ships all constructed according to the same general design. The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take as many as five to ten years to build. Improvements based on experience with building and operating the lead ship are likely to be incorporated into the design or construction of later ships in the class, so it is rare to have vessels that are identical. The second and later ships are often started before the first one is completed, launched and tested. Nevertheless, building copies is still more efficient and cost-effective than building prototypes, and the lead ship will usually be followed by copies with some improvements rather than radically different versions. The improvements will sometimes be retrofitted to the lead ship. Occasionally, the lead ship will be launched and commissioned for shakedown testing before following ship ...

Anglo-Japanese Alliance
The first was an alliance between Britain and Japan, signed in January 1902. The alliance was signed in London at Lansdowne House on 30 January 1902 by Lord Lansdowne, British Foreign Secretary, and Hayashi Tadasu, Japanese diplomat. A diplomatic milestone that saw an end to Britain's "Splendid isolation" (a policy of avoiding permanent alliances), the Anglo-Japanese alliance was renewed and expanded in scope twice, in 1905 and 1911, playing a major role in World War I before the alliance's demise in 1921 and termination in 1923. The main threat for both sides was from Russia. France was concerned about war with Britain and, in cooperation with Britain, abandoned its ally, Russia, to avoid the Russo-Japanese War of 1904. However, Britain siding with Japan angered the United States and some British dominions, whose opinion of the Empire of Japan worsened and gradually became hostile.

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles.

Eight-eight Fleet
The was a Japanese naval strategy formulated for the development of the Imperial Japanese Navy in the first quarter of the 20th century, which stipulated that the navy should include eight first-class battleships and eight armoured cruisers or battlecruisers. History and development The concept of the "Eight-Eight Fleet" originated in the aftermath of the Russo-Japanese War with the 1907 Imperial Defense Policy between the Japanese government and the competing services of the Army and Navy. The policy called for the construction of a battle fleet of eight modern battleships of 20,000 tons each and eight modern armored cruisers of 18,000 tons each. These were to be complemented by the construction of several lesser warship types, including cruisers and destroyers. The plan was inspired by the Mahanian doctrine of Satō Tetsutarō who advocated that Japanese security could only be guaranteed by a strong navy. Satō argued that to ensure security, Japan should be capable of defea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiscal Year
A fiscal year (or financial year, or sometimes budget year) is used in government accounting, which varies between countries, and for budget purposes. It is also used for financial reporting by businesses and other organizations. Laws in many jurisdictions require company financial reports to be prepared and published on an annual basis but generally not the reporting period to align with the calendar year (1 January to 31 December). Taxation laws generally require accounting records to be maintained and taxes calculated on an annual basis, which usually corresponds to the fiscal year used for government purposes. The calculation of tax on an annual basis is especially relevant for direct taxes, such as income tax. Many annual government fees—such as council tax and license fees, are also levied on a fiscal year basis, but others are charged on an anniversary basis. Some companies, such as Cisco Systems, end their fiscal year on the same day of the week each year: the day ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War Of Attrition
The War of Attrition ( ar, حرب الاستنزاف, Ḥarb al-Istinzāf; he, מלחמת ההתשה, Milhemet haHatashah) involved fighting between Israel and Egypt, Jordan, the Palestine Liberation Organisation (PLO) and their allies from 1967 to 1970. Following the 1967 Six-Day War, no serious diplomatic efforts tried to resolve the issues at the heart of the Arab–Israeli conflict. The 1967 Arab League summit formulated in September the " three no's" policy: barring peace, recognition or negotiations with Israel. The Egyptian President Gamal Abdel Nasser believed that only military initiative would compel Israel or the international community to facilitate a full Israeli withdrawal from Sinai, and hostilities soon resumed along the Suez Canal. These initially took the form of limited artillery duels and small-scale incursions into Sinai, but by 1969, the Egyptian Army judged itself prepared for larger-scale operations. On March 8, 1969, Nasser proclaimed the official ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commerce Raiding
Commerce raiding (french: guerre de course, "war of the chase"; german: Handelskrieg, "trade war") is a form of naval warfare used to destroy or disrupt logistics of the enemy on the open sea by attacking its merchant shipping, rather than engaging its combatants or enforcing a blockade against them. Privateering The first sort of commerce raiding was for nations to commission privateers. Early instances of this type of warfare were by the English and Dutch against the Spanish treasure fleets of the 16th century, which resulted in financial gain for both captain and crew upon capture of enemy vessels ("Prize (law), prizes"). 17th and 18th centuries Privateers formed a large part of the total military force at sea during the 17th and 18th centuries. In the First Anglo-Dutch War, English privateers attacked the trade on which the United Provinces of the Netherlands, United Provinces entirely depended, capturing over 1,000 Dutch merchant ships. During the subsequent Anglo-Spanish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruiser Submarine
A cruiser submarine was a very large submarine designed to remain at sea for extended periods in areas distant from base facilities. Their role was analogous to surface cruisers, cruising distant waters, commerce raiding, and scouting for the battle fleet. Cruiser submarines were successful for a brief period of World War I, but were less successful than smaller submarines during World War II. Large submarines remained vulnerable to damage from defensively equipped merchant ships (DEMS), were slow to dive if found by aircraft, offered a large sonar echo surface, and were less able to defensively maneuver during depth charge attacks.Blair, p.501 History The cruiser submarine concept originated during the unrestricted submarine warfare Unrestricted submarine warfare (February 1917), campaign of 1917. Three German Type U 139 submarines and seven former German Type U 151 submarine, merchant submarines, each armed with two guns, patrolled areas distant from their North Sea bases to sin ...

Imperial German Navy
The Imperial German Navy or the Imperial Navy () was the navy of the German Empire, which existed between 1871 and 1919. It grew out of the small Prussian Navy (from 1867 the North German Federal Navy), which was mainly for coast defence. Wilhelm II, German Emperor, Kaiser Wilhelm II greatly expanded the navy. The key leader was Admiral Alfred von Tirpitz, who greatly expanded the size and quality of the navy, while adopting the sea power theories of American strategist Alfred Thayer Mahan. The result was a Anglo-German naval arms race, naval arms race with Britain, as the German navy grew to become one of the greatest maritime forces in the world, second only to the Royal Navy. The German surface navy proved ineffective during the First World War; its only major engagement, the Battle of Jutland, was a draw, but it kept the surface fleet largely in port for the rest of the war. The submarine fleet was greatly expanded and threatened the British supply system during the Atlantic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Warfare
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, mine warfare and mine countermeasures. Submarine warfare consists primarily of diesel and nuclear submarines using torpedoes, missiles or nuclear weapons, as well as advanced sensing equipment, to attack other submarines, ships, or land targets. Submarines may also be used for reconnaissance and landing of special forces as well as deterrence. In some navies they may be used for task force screening. The effectiveness of submarine warfare partly depends on the anti-submarine warfare carried out in response. American Civil War The age of submarine warfare began during the American Civil War. The 1860s was a time of many turning points in terms of how naval warfare was fought. Many new types of warships were being developed for use in the United States and Confederate States Navies. Submarine watercraft were among the newly created vessels. The first sinking of an enemy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Japanese Navy General Staff
The was the highest organ within the Imperial Japanese Navy. In charge of planning and operations, it was headed by an Admiral headquartered in Tokyo. History Created in 1893, the Navy General Staff took over operational (as opposed to administrative) authority over the Imperial Japanese Navy from the Navy Ministry. It was responsible for the planning and execution of national defense strategy. Through the Imperial General Headquarters it reported directly to the Emperor, not to the Prime Minister, National Diet or even the Navy Ministry. It was always headed by an admiral on active duty, and was based in Tokyo. "The ministry was responsible for the naval budget, ship construction, weapons procurement, personnel, relations with the Diet and the cabinet and broad matters of naval policy. The General Staff directed the operations of the fleet and the preparation of war plans".Spector After the Washington Naval Conference of 1921–22, where Japan agreed to keep the size of its ...
