Aircraft Repair Ship
Aircraft repair ship is a naval auxiliary ship designed to provide maintenance support to aircraft. Aircraft repair ships provide similar services to seaplane tenders, that also cared for the crew. Aircraft repair ships had their own stores of spare parts, like a depot ship. Aircraft repair ships had repair personnel and equipment to repair failures or battle damage on aircraft. Aircraft repair ship also did regular aircraft maintenance.Lenton & Colledge, p.333 United States Navy During World War II there was a great demand for aircraft repair ships. The United States Navy aircraft repair ship were manned by repair units, called Carrier Aircraft Service Units. If needed a Carrier Aircraft Service Unit could be redesignated into a Combat Aircraft Service Unit, Scout Observation Service unit or Patrol Service units. These units could also be land-based or on an aircraft repair ship. Some cargo ships were converted into aircraft repair ships to aid in the repair needs of the Worl ...

Blimp
A blimp, or non-rigid airship, is an airship (dirigible) without an internal structural framework or a keel. Unlike semi-rigid and rigid airships (e.g. Zeppelins), blimps rely on the pressure of the lifting gas (usually helium, rather than hydrogen) inside the envelope and the strength of the envelope itself to maintain their shape. Principle Since blimps keep their shape with internal overpressure, typically the only solid parts are the passenger car (gondola) and the tail fins. A non-rigid airship that uses heated air instead of a light gas (such as helium) as a lifting medium is called a hot-air airship (sometimes there are battens near the bow, which assist with higher forces there from a mooring attachment or from the greater aerodynamic pressures there). Volume changes of the lifting gas due to temperature changes or to changes of altitude are compensated for by pumping air into internal ballonets (air bags) to maintain the overpressure. Without sufficient overpressur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing 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] |
Liberty Ship
Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. Their production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types during World War I. The immensity of the effort, the number of ships built, the role of female workers in their construction, and the survival of some far longer than their original five-year design life combine to make them th ...

Operation Ivory Soap
Operation Ivory Soap was a classified United States military project to provide forward theatre support for aircraft repair and maintenance during World War II in the Pacific Theatre of Operations. Six Liberty ships were converted into floating shops to repair aircraft. They were designated Aircraft Repair Units (Floating). The Liberty ships were retrofitted to repair B-29 bombers. Eighteen smaller long auxiliary vessels were designated as Aircraft Maintenance Units. The smaller vessels were intended to repair fighter aircraft like the P-51 Mustang, Lockheed P-38, Sikorsky R-4 helicopters, and amphibious vehicles. The island-hopping strategy employed in campaigns like Operation Cartwheel necessitated more flexibility to support aircraft operations at rapidly shifting, far-flung island airfields. Once an island was taken it was used as a forward airfield for aircraft returning from long range missions where they were repaired, rearmed, and made ready for the next vital mission. T ...

Pacific War
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War. The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more widely accepted that the Pacific War itself began on 7 December (8 December Japanese time) 1941, when the Japanese simultaneously invaded Thailand, attacked the British colonies of Malaya, Singapore, and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island, Guam, and the Philippines. The Pacific War saw the Allies pitted against Japan, the latter ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Army Air Forces
The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II (1941–1945). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six United States Armed Forces, armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Chief of Staff of the United States Army, Army Chief of Staff. The AAF administered all parts of military aviation formerly distributed am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vietnam War
The Vietnam War (also known by #Names, other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was United States in the Vietnam War, supported by the United States and other anti-communism, anti-communist Free World Military Forces, allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French 1954 Geneva Conference, military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh to ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Mechanic
A mechanic is an artisan, skilled tradesperson, or technician who uses tools to build, maintain, or repair machinery, especially cars. Duties Most mechanics specialize in a particular field, such as auto body mechanics, air conditioning and refrigeration mechanics, auto mechanics, bicycle mechanics, boiler mechanics, and other areas. A mechanic is typically certified by a trade association or regional government power. Mechanics may be separated into two classes based on the type of machines they work on, heavyweight and lightweight. Heavyweight work is on larger machines or heavy equipment, such as tractors and trailers, while lightweight work is on smaller items, such as automotive engines. Automotive mechanics/automotive technicians Automotive technicians (the modern term of reference) have many trades within. Some may specialize in the electrical diagnosis, while others may specialize in the mechanical aspects. Other mechanical areas include: brakes and steering, sus ...

Barracks
Barracks are usually a group of long buildings built to house military personnel or laborers. The English word originates from the 17th century via French and Italian from an old Spanish word "barraca" ("soldier's tent"), but today barracks are usually permanent buildings for military accommodation. The word may apply to separate housing blocks or to complete complexes, and the plural form often refers to a single structure and may be singular in construction. The main object of barracks is to separate soldiers from the civilian population and reinforce discipline, training, and ''esprit de corps''. They have been called "discipline factories for soldiers". Like industrial factories, some are considered to be shoddy or dull buildings, although others are known for their magnificent architecture such as Collins Barracks in Dublin and others in Paris, Berlin, Madrid, Vienna, or London. From the rough barracks of 19th-century conscript armies, filled with hazing and illness and bare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
