Watertown, Massachusetts
Watertown is a city in Middlesex County, Massachusetts, and is part of Greater Boston. The population was 35,329 in the 2020 census. Its neighborhoods include Bemis, Coolidge Square, East Watertown, Watertown Square, and the West End. Watertown was one of the first Massachusetts Bay Colony settlements organized by Puritan settlers in 1630. The city is home to the Perkins School for the Blind, the Armenian Library and Museum of America, and the historic Watertown Arsenal, which produced military armaments from 1816 through World War II. History Archeological evidence suggests that Watertown was inhabited for thousands of years before colonization. In the 1600s, two groups of Massachusett, the Pequossette and the Nonantum, had settlements on the banks of the river later called the Charles, and a contemporary source lists "Pigsgusset" as the native name of "Water towne." The Pequossette built a fishing weir to trap herring at the site of the current Watertown Dam. The an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machinist
A machinist is a tradesperson or trained professional who not only operates machine tools, but also has the knowledge of tooling and materials required to create set ups on machine tools such as milling machines, grinders, lathes, and drilling machines. A competent machinist should have a well-developed mechanical aptitude, the ability to correctly use precision measuring instruments, and a working knowledge of the proper speeds and feeds required for successfully utilizing the various work and tool materials commonly used in most machining operations. Nature of work Mass-produced parts of machines are more common today, but still require machinists and millwrights to calibrate and install machine parts to manufacture other parts. In many parts of the economy, however, custom-made parts are required for various uses. A machinist may work on manufacturing something simple like a motorcycle frame part, a piece of an internal combustion motor, or something extraordinarily complex, ...

Big Week
Big Week or Operation Argument was a sequence of raids by the United States Army Air Forces and RAF Bomber Command from 20 to 25 February 1944, as part of the European strategic bombing campaign against Nazi Germany. The planners intended to attack the German aircraft industry to lure the ''Luftwaffe'' into a decisive battle where the Luftwaffe could be damaged so badly that the Allies would achieve air superiority which would ensure success of the invasion of continental Europe. The joint daylight bombing campaign was also supported by RAF Bomber Command operating against the same targets at night. Arthur "Bomber" Harris resisted contributing RAF Bomber Command so as not to dilute the British "area bombing" offensive. It took an order from Air Chief Marshal Sir Charles Portal, Chief of the Air Staff, to force Harris to comply. RAF Fighter Command also provided escort for USAAF bomber formations, just at the time that the Eighth Air Force had started introducing the P-51 ...

Messerschmitt Bf 109
The Messerschmitt Bf 109 is a German World War II fighter aircraft that was, along with the Focke-Wulf Fw 190, the backbone of the Luftwaffe's fighter force. The Bf 109 first saw operational service in 1937 during the Spanish Civil War and was still in service at the end of World War II in 1945. It was one of the most advanced fighters when it first appeared, with an all-metal monocoque construction, a closed canopy, and retractable landing gear. It was powered by a liquid-cooled, inverted-V12 aero engine. It was called the Me 109 by Allied aircrew and some German aces, even though this was not the official German designation. It was designed by Willy Messerschmitt and Robert Lusser who worked at Bayerische Flugzeugwerke during the early to mid-1930s. It was conceived as an interceptor, although later models were developed to fulfill multiple tasks, serving as bomber escort, fighter-bomber, day-, night-, all-weather fighter, ground-attack aircraft, and reconnais ...

Papenburg
Papenburg (; East Frisian Low Saxon: ''Papenbörg'') is a city in the district of Emsland, Lower Saxony, Germany, situated at the river Ems. It is known for its large shipyard, the Meyer-Werft, which specializes in building cruise liners. Geography Districts Papenburg is subdivided into 6 urban districts, Papenburg-Untenende, Papenburg-Obenende, Herbrum, Tunxdorf-Nenndorf, Aschendorf and Bokel. History In the ''Chronicle of the Frisians'', written in the 16th century by the East-Frisian council Eggerik Benninga, the Papenburg (at that time a manor) is mentioned for the first time. In 1458, Hayo von Haren, called "von der Papenburch", confessed to be leaned with the Papenburg. The contract that was made because of this is the earliest verifiably documented mention of Papenburg. On 2 December 1630, the district administrator Dietrich von Velen purchased the manor for 1500 Reichsthaler from Friedrich von Schwarzenberg in order to found a settlement in the fen-surrounded regi ...

Messerschmitt Bf 110
The Messerschmitt Bf 110, often known unofficially as the Me 110,Because it was built before ''Bayerische Flugzeugwerke'' became Messerschmitt AG in July 1938, the Bf 110 was never officially given the designation Me 110. is a twin-engine (Destroyer, heavy fighter), fighter-bomber (''Jagdbomber'' or ''Jabo''), and night fighter (''Nachtjäger'') developed in Nazi Germany in the 1930s and used by the Luftwaffe during World War II. Hermann Göring was a proponent of the Bf 110, believing its heavy armament, speed, and range would make the Bf 110 the Luftwaffe’s premier offensive fighter. Early variants were armed with two MG FF 20 mm cannon, four 7.92 mm (.312 in) MG 17 machine guns, and one 7.92 mm (.312 in) MG 15 machine gun for defence (later variants would replace the MG FFs with MG 151s and the rear gunner station would be armed with the twin-barreled MG 81Z). Development work on an improved type to replace the Bf 110 - the Messerschmitt Me 210 - bega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

P-47 Thunderbolt
The Republic P-47 Thunderbolt is a World War II-era fighter aircraft produced by the American company Republic Aviation from 1941 through 1945. It was a successful high-altitude fighter and it also served as the foremost American fighter-bomber in the ground-attack role. Its primary armament was eight .50-caliber machine guns, and it could carry 5-inch rockets or a bomb load of . When fully loaded, the P-47 weighed up to 8 tons, making it one of the heaviest fighters of the war. The Thunderbolt was effective as a short-to medium-range escort fighter in high-altitude air-to-air combat and ground attack in both the European and Pacific theaters. The P-47 was designed around the powerful Pratt & Whitney R-2800 Double Wasp 18-cylinder radial engine, which also powered two U.S. Navy/U.S. Marine Corps fighters, the Grumman F6F Hellcat and the Vought F4U Corsair. An advanced turbosupercharger system ensured the aircraft's eventual dominance at high altitudes, while also inf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
