Northrop Aircraft
Northrop Corporation was an American aircraft manufacturer from its formation in 1939 until its 1994 merger with Grumman to form Northrop Grumman. The company is known for its development of the flying wing design, most successfully the B-2 Spirit stealth bomber.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 93-106, Cypress, CA, 2013. . History Jack Northrop founded 3 companies using his name. The first was the Avion Corporation in 1928, which was absorbed in 1929 by the United Aircraft and Transport Corporation as a subsidiary named "Northrop Aircraft Corporation" (and later became part of Boeing). The parent company moved its operations to Kansas in 1931, and so Jack, along with Donald Douglas, established a "Northrop Corporation" located in El Segundo, California, which produced several successful designs, including the Northrop Gamma and Northrop Delta. However, labor difficulties led to the dissolution of the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Re ...

El Segundo, California
El Segundo ( , ; ) is a city in Los Angeles County, California, United States. Located on Santa Monica Bay, it was incorporated on January 18, 1917, and is part of the South Bay Cities Council of Governments. The population was 16,731 as of the 2020 census, a 0.5% increase from 16,654 in the 2010 census. History The El Segundo and Los Angeles coastal area was first settled by the Tongva (or Gabrieleños) Native American tribes thousands of years ago. The area was once a part of ''Rancho Sausal Redondo'' ("Round Willow Patch Ranch"). Rancho Sausal Redondo extended from Playa Del Rey in the north to Redondo Beach in the south. Originally a Mexican land grant owned by Antonio Ygnacio Avila, the rancho was later purchased by a Scottish baronet named Sir Robert Burnett. After his return to Scotland, the property was purchased by then-manager of the rancho, Daniel Freeman. Daniel Freeman sold portions of the rancho to several persons. George H. Peck owned the of land where the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop F-89 Scorpion
The Northrop F-89 Scorpion was an American all-weather, twin-engined interceptor aircraft built during the 1950s, the first jet-powered aircraft designed for that role from the outset to enter service. Though its straight wings limited its performance, it was among the first United States Air Force (USAF) jet fighters equipped with guided missiles and notably the first combat aircraft armed with air-to-air nuclear weapons (the unguided Genie rocket). Design and development The Scorpion stemmed from a United States Army Air Forces (USAAF) Air Technical Service Command specification ("Military Characteristics for All-Weather Fighting Aircraft") for a night fighter to replace the P-61 Black Widow. The preliminary specification, sent to aircraft manufacturers on 28 August 1945, required two engines and an armament of six guns, either machine guns or autocannon. The revised specification was issued on 23 November; it did not specify jet propulsion, but the desired maximum speed of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop YB-49
The Northrop YB-49 was an American prototype jet-powered heavy bomber developed by Northrop Corporation shortly after World War II for service with the United States Air Force. The YB-49 featured a flying wing design and was a turbojet-powered development of the earlier, piston-engined Northrop XB-35 and YB-35. The two YB-49s actually built were both converted YB-35 test aircraft. The YB-49 never entered production, being passed over in favor of the more conventional Convair B-36 piston-driven design. Design work performed in the development of the YB-35 and YB-49 nonetheless proved to be valuable to Northrop decades later in the eventual development of the B-2 stealth bomber, which entered service in the early 1990s. Design and development With the XB-35 program seriously behind schedule by 1944, and the end of piston-engined combat aircraft in sight, the production contract for this propeller-driven type was cancelled in May of that year. Nevertheless, the Flying Wing des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop YB-35
The Northrop YB-35, Northrop designation N-9 or NS-9, were experimental heavy bomber aircraft developed by the Northrop Corporation for the United States Army Air Forces during and shortly after World War II. The airplane used the radical and potentially very efficient flying wing design, in which the tail section and fuselage are eliminated and all payload is carried in a thick wing. Only prototypes and pre-production aircraft were built, although interest remained strong enough to warrant further development of the design as a jet bomber, under the designation Northrop YB-49, YB-49.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 93, 95, 103–6, Cypress, CA, 2013. . Design and development The B-35 was the brainchild of John Knudsen Northrop, Jack Northrop, who made the flying wing the focus of his work during the 1930s. In 1941 before the USA entered World War II, Northrop and Consolidated Vultee Corporation had been c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Night Fighter
A night fighter (also known as all-weather fighter or all-weather interceptor for a period of time after the Second World War) is a fighter aircraft adapted for use at night or in other times of bad visibility. Night fighters began to be used in World War I and included types that were specifically modified to operate at night. During the Second World War, night fighters were either purpose-built night fighter designs, or more commonly, heavy fighters or light bombers adapted for the mission, often employing radar or other systems for providing some sort of detection capability in low visibility. Many night fighters of the conflict also included instrument landing systems for landing at night, as turning on the runway lights made runways into an easy target for opposing intruders. Some experiments tested the use of day fighters on night missions, but these tended to work only under very favourable circumstances and were not widely successful. Avionics systems were greatly mini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop P-61 Black Widow
The Northrop P-61 Black Widow is a twin-engine United States Army Air Forces fighter aircraft of World War II. It was the first operational U.S. warplane designed as a night fighter, and the first aircraft designed specifically as a night fighter. Named for the North American spider ''Latrodectus mactans'', it was an all-metal, twin-engine, twin-boom design armed with four forward-firing 20 mm (.79 in) Hispano M2 autocannon in the lower fuselage, and four M2 Browning machine guns in a dorsal gun turret. Developed during the war, the first test flight was made on May 26, 1942, with the first production aircraft rolling off the assembly line in October 1943. Although not produced in the large numbers of its contemporaries, the Black Widow was operated effectively as a night fighter by United States Army Air Forces squadrons in the European Theater, Pacific Theater, China Burma India Theater, and Mediterranean Theater during World War II. It replaced earlier British ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whiz Kids (Department Of Defense)
Whiz Kids was a name given to a group of experts from RAND Corporation with which Robert McNamara surrounded himself in order to turn around the management of the United States Department of Defense (DoD) in the 1960s. The purpose was to shape a modern defense strategy in the Nuclear Age by bringing in economic analysis, operations research, game theory, computing, as well as implementing modern management systems to coordinate the huge dimension of operations of the DoD with methods such as the Planning, Programming, and Budgeting System (PPBS). They were called the Whiz Kids recalling the group at Ford Motor Company that McNamara was part of a decade earlier.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
