B-29 Superfortress
The Boeing B-29 Superfortress is an American four-engined 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 B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets. The $3 billion cost of design and production (equivalent to $ billion today), far exceeding the $1.9 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
702nd Tactical Air Support Squadron
The 702d Tactical Air Support Squadron is an inactive United States Air Force unit. It was part of the 601st Tactical Air Control Wing at Bergstrom Air Force Base, Texas, from 1969 until it was inactivated on 30 November 1975. The earliest predecessor of the squadron was organized during the expansion of the armed forces of the United States prior to its entry into World War II as the 12th Reconnaissance Squadron. The squadron was redesignated the 402d Bombardment Squadron in the spring of 1942, and became an Operational Training Unit and later a Replacement Training Unit until 1944, when it was inactivated in a reorganization of Army Air Forces training units. The squadron was reactivated the same day as a Boeing B-29 Superfortress unit, but inactivated shortly thereafter as B-29 units reorganized from four to three squadrons. It was then activated as a component of a different group. It served in combat in the Pacific Theater, where it was awarded the Distinguished Unit C ...

Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Oil Refinery
An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemicals feedstock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha. The crude oil feedstock has typically been processed by an oil production plant. There is usually an oil depot at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products. In 2020, the total capacity of global refineries for crude oil was about 101.2 million barrels per day. Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units, such as distillation colu ...

Rota (island)
Rota (Chamorro: Luta), also known as the "Friendly Island", is the southernmost island of the United States Commonwealth of the Northern Mariana Islands (CNMI) and the second southernmost of the Marianas Archipelago. In early Spanish records it is called "Zarpana"; the name Rota may have come from the Spaniards possibly naming the island after the municipality of Rota, Spain. It lies approximately north-northeast of the United States territory of Guam. Sinapalo village is the largest and most populated, followed by Songsong village (Songsong). Rota also functions as one of the four municipalities of the CNMI. History In 1521, the first European to see Rota was the lookout on Ferdinand Magellan's ship ''Victoria'', Lope Navarro. However, Magellan's armada of three ships did not stop until they reached Guam, so the first European to arrive in Rota (in 1524), was the Spanish navigator Juan Sebastián Elcano, who annexed it together with the rest of the Mariana Islands on behalf o ...

Quonset Hut
A Quonset hut is a lightweight prefabricated structure of corrugated galvanized steel having a semi cylindrical cross-section. The design was developed in the United States, based on the Nissen hut introduced by the British during World War I. Hundreds of thousands were produced during World War II and military surplus was sold to the public. The name comes from the site of their first deployment at Quonset Point at the Davisville Naval Construction Battalion Center in Davisville, Rhode Island. Design and history The first Quonset huts were manufactured in 1941 when the United States Navy needed an all-purpose, lightweight building that could be shipped anywhere and assembled without skilled labor. The George A. Fuller construction company manufactured them, and the first was produced within 60 days of signing the contract. In 1946, the Great Lakes Steel Corporation claimed "the term 'Quonset,' as applied to builders and building materials, is a trade mark owned by the Grea ...
