Superfortresses
The Boeing B-29 Superfortress is an American four-engined Propeller (aeronautics), propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the Boeing B-17 Flying Fortress, B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bomber, strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan.

Atomic Bombings Of Hiroshima And Nagasaki
The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August 1945, respectively. The two bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in armed conflict so far. In the final year of World War II, the Allies prepared for a costly invasion of the Japanese mainland. This undertaking was preceded by a conventional and firebombing campaign that devastated 64 Japanese cities. The war in the European theatre concluded when Germany surrendered on 8 May 1945, and the Allies turned their full attention to the Pacific War. By July 1945, the Allies' Manhattan Project had produced two types of atomic bombs: "Fat Man", a plutonium implosion-type nuclear weapon; and "Little Boy", an enriched uranium gun-type fission weapon. The 509th Composite Group of the United States Army Air Forces was trained and equipped with the specialized Silverplate version of the ...

Marianas
The Mariana Islands (; also the Marianas; in Chamorro: ''Manislan Mariånas'') 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.

Combined Chiefs Of Staff
The Combined Chiefs of Staff (CCS) was the supreme military staff for the United States and Britain during World War II. It set all the major policy decisions for the two nations, subject to the approvals of British Prime Minister Winston Churchill and U.S. President Franklin D. Roosevelt. History It emerged from the meetings of the Arcadia Conference in Washington, from December 22, 1941 to January 14, 1942. Shortly after Pearl Harbor, Prime Minister Churchill and his senior military staff used Arcadia as an opportunity to lay out the general strategy for the war. The American Army Chief of Staff George Marshall came up with the idea of a combined board, and sold it to Roosevelt and together the two sold the idea to Churchill. Churchill's military aides were much less favorable, and General Alan Brooke, the chief of the British Armed Forces, was strongly opposed. Brooke believed that if the Western Allies were placed under international unified commands the United States would bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steel Mills
A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap. History Since the invention of the Bessemer process, steel mills have replaced ironworks, based on Puddling (metallurgy), puddling or Finery forge, fining methods. New ways to produce steel appeared later: from scrap melted in an electric arc furnace and, more recently, from direct reduced iron processes. In the late 19th and early 20th centuries the world's largest steel mill was the Barrow Hematite Steel Company, Barrow Hematite Steel Company steelworks located in Barrow-in-Furness, United Kingdom. Today, the world's largest steel mill is in Gwangyang, South Korea. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
