Operation Z (1944)
Operation Z was a defensive plan put into place by the Japanese during World War II to defend the Marianas Islands, and in particular, Saipan. Background Early in 1944, the United States military set their eyes on the Marshall Islands after landing on Kwajalein Atoll. To help with the attack, on February 17, 1944, they bombarded Truk, Caroline Islands, due to its proximity to the Marshall Islands. During this bombardment, the Japanese lost 300 aircraft and some 200,000 tons of merchant shipping. Defense of Marianas With the impending invasion of the Marianas Islands, Admiral Mineichi Koga, on March 8, sponsored Operation Z, as a defense against the American attack. This plan was approved by the Imperial Japanese Navy General Staff, with a formal title of ''Combined Fleet Secret Operations Order No. 73''. The operation called for the utilization of the remaining land-based aircraft numbering approximately 1055 in the Marianas, the Caroline Islands, and in western New Guinea. Th ...

Imperial Japanese 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.

Filipino People
Filipinos ( tl, Mga Pilipino) are the people who are citizens of or native to the Philippines. The majority of Filipinos today come from various Austronesian ethnolinguistic groups, all typically speaking either Filipino, English and/or other Philippine languages. Currently, there are more than 185 ethnolinguistic groups in the Philippines; each with its own language, identity, culture and history. Names The name ''Filipino'', as a demonym, was derived from the term ''Las Islas Filipinas'' ("the Philippine Islands"), the name given to the archipelago in 1543 by the Spanish explorer and Dominican priest Ruy López de Villalobos, in honor of Philip II of Spain (Spanish: ''Felipe II''). During the Spanish colonial period, natives of the Philippine islands were usually known by the generic terms ''indio'' ("Indian") or ''indigenta'' ("indigents"). However, during the early Spanish colonial period the term ''Filipinos'' or ''Philipinos'' was sometimes used by Spanish writers ...

Operation A-Go
The Battle of the Philippine Sea (June 19–20, 1944) was a major naval battle of World War II that eliminated the Imperial Japanese Navy's ability to conduct large-scale carrier actions. It took place during the United States' amphibious invasion of the Mariana Islands during the Pacific War. The battle was the last of five major "carrier-versus-carrier" engagements between American and Japanese naval forces, and pitted elements of the United States Navy's Fifth Fleet against ships and aircraft of the Imperial Japanese Navy's Mobile Fleet and nearby island garrisons. This was the largest carrier-to-carrier battle in history, involving 24 aircraft carriers, deploying roughly 1,350 carrier-based aircraft. The aerial part of the battle was nicknamed the Great Marianas Turkey Shoot by American aviators for the severely disproportional loss ratio inflicted upon Japanese aircraft by American pilots and anti-aircraft gunners. During a debriefing after the first two air battles, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chester Nimitz
Chester William Nimitz (; February 24, 1885 – February 20, 1966) was a fleet admiral in the United States Navy. He played a major role in the naval history of World War II as Commander in Chief, US Pacific Fleet, and Commander in Chief, Pacific Ocean Areas, commanding Allied air, land, and sea forces during World War II. Nimitz was the leading US Navy authority on submarines. Qualified in submarines during his early years, he later oversaw the conversion of these vessels' propulsion from gasoline to diesel, and then later was key in acquiring approval to build the world's first nuclear-powered submarine, , whose propulsion system later completely superseded diesel-powered submarines in the US. He also, beginning in 1917, was the Navy's leading developer of underway replenishment techniques, the tool which during the Pacific war would allow the US fleet to operate away from port almost indefinitely.

Allied Translator And Interpreter Section
The Allied Translator and Interpreter Section (ATIS), also known as the Allied Translator and Interpreter Service or Allied Translator and Intelligence Service, was a joint Australian/ American World War II intelligence agency which served as a centralized allied intelligence unit for the translation of intercepted Japanese communications, interrogations and negotiations in the Pacific Theater of Operations between September 1942 – December 1945.

Military Intelligence Service (United States)
The Military Intelligence Service ( ja, アメリカ陸軍情報部, ''America Rikugun Jōhōbu'') was a World War II U.S. military unit consisting of two branches, the Japanese American unit (described here) and the German-Austrian unit based at Camp Ritchie, best known as the "Ritchie Boys". The unit described here was primarily composed of ''Nisei'' (second-generation Japanese Americans) who were trained as linguists. Graduates of the MIS language school (MISLS) were attached to other military units to provide translation, interpretation, and interrogation services. Major General Charles Willoughby said, “The ''Nisei'' shortened the Pacific War by two years and saved possibly a million American lives.” They served with the United States Army, Navy, and Marine Corps, as well as with British, Australian, New Zealand, Canadian, Chinese, and Indian combat units fighting the Japanese.

Plain Text
In computing, plain text is a loose term for data (e.g. file contents) that represent only characters of readable material but not its graphical representation nor other objects (floating-point numbers, images, etc.). It may also include a limited number of "whitespace" characters that affect simple arrangement of text, such as spaces, line breaks, or tabulation characters (although tab characters can "mean" many different things, so are hardly "plain"). Plain text is different from formatted text, where style information is included; from structured text, where structural parts of the document such as paragraphs, sections, and the like are identified; and from binary files in which some portions must be interpreted as binary objects (encoded integers, real numbers, images, etc.). The term is sometimes used quite loosely, to mean files that contain ''only'' "readable" content (or just files with nothing that the speaker doesn't prefer). For example, that could exclude any indic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depth Charging
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive hydraulic shock. Most depth charges use high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a surface ship, or another ...
