Allied Naval Bombardments Of Japan During World War II
The allied naval bombardments of Japan took place during the last weeks of the Pacific War in 1945, in which warships of the United States Navy, the Royal Navy and the Royal New Zealand Navy bombarded industrial and military facilities in Japan. Most of these bombardments were conducted by battleships and cruisers, and caused heavy damage to several of the targeted factories, as well as nearby civilian areas. A major goal of the attacks was to provoke the Japanese military into committing some of its reserve force of aircraft into battle. However, the Japanese did not attempt to attack the Allied bombardment forces, and none of the involved warships suffered any damage. The major bombardments began on 14 and 15 July 1945, when US Navy warships attacked the cities of Kamaishi and Muroran. The next attack was made by a joint American and British force against the city of Hitachi during the night of 17/18 July. Groups of cruisers and destroyers subsequently shelled the Nojima Sa ...

Japan Campaign
The Japan campaign was a series of battles and engagements fought in and around the Japanese archipelago, Japanese home islands, between Allies of World War II, Allied forces and the forces of Empire of Japan, Imperial Japan during the last stages of the Pacific War, Pacific campaign of World War II. The Japan campaign lasted from around June 1944 to the end of the Pacific War in August 1945. Air war Periodic air raids on Japan were the first attacks undertaken by Allied forces against the Japanese mainland. In late 1944, these raids were followed by a major strategic bombing against cities, factories, and other war infrastructure throughout Japan, most notably: * The Bombing of Tokyo (10 March 1945), Operation Meetinghouse raid on Tokyo (9-10 March 1945): 100,000 Japanese were killed, mostly civilians, including in the conflagration that followed the firebombing. * The Bombing of Kure (July 1945), Bombing of Kure (24-28 July 1945): Most of the surviving large Japanese warships ...

United States Pacific Fleet
The United States Pacific Fleet (USPACFLT) is a theater-level component command of the United States Navy, located in the Pacific Ocean. It provides naval forces to the Indo-Pacific Command. Fleet headquarters is at Joint Base Pearl Harbor–Hickam, Hawaii, with large secondary facilities at Naval Air Station North Island, California. Origins A Pacific Fleet was created in 1907 when the Asiatic Squadron and the Pacific Squadron were combined. In 1910, the ships of the First Squadron were organized back into a separate Asiatic Fleet. The General Order 94 of 6 December 1922 organized the United States Fleet, with the Battle Force as the Pacific presence. Until May 1940, the Battle Force was stationed on the West Coast of the United States. Headquarters, battleships, aircraft carriers and heavy cruisers were stationed at San Pedro close to the Long Beach Naval Shipyard. Light cruisers, destroyers and submarines were stationed at San Diego. During the summer of 1940, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering carrier-based aircraft, shipborne aircraft. Typically it is the capital ship of a naval fleet, fleet (known as a carrier battle group), as it allows a naval force to power projection, project seaborne naval aviation, air power far from homeland without depending on local airfields for staging area, staging aerial warfare, aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear marine propulsion, nuclear-powered supercarriers that carry dozens of fighter aircraft, fighters, strike aircraft, military helicopters, airborne early warning and control, AEW&Cs and other types of aircraft such as unmanned combat aerial vehicle, UCAVs. While heavier fixed-wing aircraft such as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fast Battleship
A fast battleship was a battleship which in concept emphasised speed without undue compromise of either armor or armament. Most of the early World War I-era dreadnought battleships were typically built with low design speeds, so the term "fast battleship" is applied to a design which is considerably faster. The extra speed of a fast battleship was normally required to allow the vessel to carry out additional roles besides taking part in the line of battle, such as escorting aircraft carriers. A fast battleship was distinguished from a battlecruiser in that it would have been expected to be able to engage hostile battleships in sustained combat on at least equal terms. The requirement to deliver increased speed without compromising fighting ability or protection was the principal challenge of fast battleship design. While increasing length-to-beam ratio was the most direct method of attaining a higher speed, this meant a bigger ship that was considerably more costly and/or could e ...

Caliber (artillery)
In artillery, caliber or calibre''Caliber'' is the American English spelling, while ''calibre'' is used in British English. is the internal diameter of a gun barrel, or, by extension, a relative measure of the barrel length. Rifled barrels Rifled barrels introduce ambiguity to measurement of caliber. A rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land. Projectiles fired from rifled barrels must be of the full groove-to-groove diameter to be effectively rotated by the rifling, but the caliber has sometimes been specified as the land-to-land diameter before rifling grooves were cut. The depth of rifling grooves (and the consequent ambiguity) increases in larger calibers. Steel artillery projectiles may have a forward bourrelet section machined to a diameter slightly smaller than the original land-to-land dimension of the barrel and a copper driving band somewhat larger than ...

Coastal Artillery
Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications. From the Middle Ages until World War II, coastal artillery and naval artillery in the form of cannons were highly important to military affairs and generally represented the areas of highest technology and capital cost among materiel. The advent of 20th-century technologies, especially military aviation, naval aviation, jet aircraft, and guided missiles, reduced the primacy of cannons, battleships, and coastal artillery. In countries where coastal artillery has not been disbanded, these forces have acquired amphibious capabilities. In littoral warfare, mobile coastal artillery armed with surface-to-surface missiles can still be used to deny the use of sea lanes. It was long held as a rule of thumb that one shore-based gun equaled three naval guns of the same caliber, due to the steadiness of the coastal gun which allowed ...

Operation Downfall
Operation Downfall was the proposed Allied plan for the invasion of the Japanese home islands near the end of World War II. The planned operation was canceled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the invasion of Manchuria. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in November 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island, Kyūshū, with the recently captured island of Okinawa to be used as a staging area. In early 1946 would come Operation Coronet, the planned invasion of the Kantō Plain, near Tokyo, on the main Japanese island of Honshu. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet. If Downfall had taken place, it would have been the largest amphibious operation in history, surpassing D-Day. Japan's geography made this inva ...

Imperial Japanese Army Air Service
The Imperial Japanese Army Air Service (IJAAS) or Imperial Japanese Army Air Force (IJAAF; ) was the Military aviation, aviation force of the Imperial Japanese Army (IJA). Its primary mission was to provide tactical close air support for ground forces, as well as a limited air interdiction capability. The IJAAS also provided aerial reconnaissance to other branches of the IJA. While the IJAAS engaged in Strategic bombing during World War II, strategic bombing of cities such as Shanghai, Battle of Nanking#Aerial bombardment of Nanking, Nanjing, Guangzhou, Canton, Bombing of Chongqing, Chongqing, Bombing of Rangoon in World War II, Rangoon, and Bombing of Mandalay (1942), Mandalay, this was not the primary mission of the IJAAS, and it lacked a heavy bomber force. It did not usually control artillery spotter/observer aircraft; artillery battalions controlled the light aircraft and observation balloon, balloons that operated in these roles. The Imperial Japanese Navy Air Service was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, Potsdam Declaration, when it was dissolved following surrender of Japan, Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952 and 1954 after the dissolution of the IJN. The IJN 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 reconnaissance and airstrike operations from the fleet. It was the primary opponent of the Allies of World War II, Western Allies in the Pacific War. The IJN additionally fielded Imperial Japanese Navy land forces, limited land-based forces, including Special Naval Landing Forces, professional marines, Japanese marine paratroopers of World War II, marine paratrooper units, anti-aircraft defense units ...

Allied Submarines In The Pacific War
Allied submarines were used extensively during the Pacific War and were a key contributor to the defeat of the Empire of Japan. During the war, submarines of the United States Navy were responsible for 56% of Japan's merchant marine losses; other Allied navies added to the toll. The war against shipping was the single most decisive factor in the collapse of the Japanese economy. Allied submarines also sank a large number of Imperial Japanese Army (IJA) troop transports, killing many thousands of Japanese soldiers and hampering the deployment of IJA reinforcements during the battles on the Pacific islands. They also conducted reconnaissance patrols, landed special forces and guerrilla troops and performed search and rescue tasks. The majority of the submarines involved were from the U.S. Navy, with the British Royal Navy committing the second largest number of boats and the Royal Netherlands Navy contributing smaller numbers of boats. The Allied submarine campaign is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mariana Islands
The Mariana Islands ( ; ), also simply the Marianas, are a crescent-shaped archipelago comprising the summits of fifteen longitudinally oriented, mostly dormant volcanic mountains in the northwestern Pacific Ocean, between the 12th and 21st parallels north and along the 145th meridian east. They lie south-southeast of Japan, west-southwest of Hawaii, north of New Guinea, and east of the Philippines, demarcating the Philippine Sea's eastern limit. They are found in the northern part of the western Oceanic sub-region of Micronesia, and are politically divided into two jurisdictions of the United States: the Commonwealth of the Northern Mariana Islands and, at the southern end of the chain, the territory of Guam. The islands were named after the influential Spanish queen Mariana of Austria following their colonization in the 17th century. The indigenous inhabitants are the Chamorro people. Archaeologists in 2013 reported findings which indicated that the people who first settl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
