Michoud Assembly Facility
The Michoud Assembly Facility (MAF) is an manufacturing complex owned by NASA in New Orleans East, a district within New Orleans, Louisiana, in the United States. Organizationally it is part of NASA's Marshall Space Flight Center, and is currently a multi-tenant complex to allow commercial and government contractors, as well as government agencies, to use the site. MAF is one of the largest manufacturing plants in the world with 43 environmentally controlled acres——under one roof, and it employs more than 4,200 people. From September 1961 to the end of the Apollo program in December 1972 the site was utilized by Chrysler Corporation to build the first stages of the Saturn I and Saturn IB, later joined by Boeing Corporation to build the first stage of the Saturn V rockets. From September 5, 1973, to September 20, 2010, the factory was used for the construction of the Space Shuttle's external fuel tanks by Martin Marietta Corporation. In 2012, the parts of the facil ...

Artemis 1
Artemis 1, officially Artemis I and formerly Exploration Mission-1 (EM-1), was an uncrewed Moon-orbiting mission. As the first major spaceflight of NASA's Artemis program, Artemis 1 marked the return of the agency to lunar exploration originally begun as the Apollo program decades earlier. It was the first integrated flight test of the Orion spacecraft and Space Launch System (SLS) rocket. Its main objective was to test the Orion spacecraft, especially its heat shield, in preparation for subsequent Artemis missions. These missions seek to reestablish a human presence on the Moon and demonstrate technologies and business approaches needed for future scientific studies, including exploration of Mars. The Orion spacecraft for Artemis 1 was stacked on October 20, 2021, marking the first time a super-heavy-lift vehicle has been stacked inside NASA's Vehicle Assembly Building (VAB) since the final Saturn V in 1973. On August 17, 2022, the fully stacked vehicle was rolled out fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saturn C-8
The Saturn C-8 was the largest member of the Saturn series of rockets to be designed. It was a potential alternative to the Nova rocket, should NASA have chosen a direct ascent method of lunar exploration for the Apollo program. The first stage was an increased-diameter version of the S-IC. The second stage was an increased-diameter version of the S-II. Both of these stages had eight engines, as opposed to the standard five. The third stage was a stretched S-IVB stage, which retained its original diameter and engine. NASA announced on September 7, 1961, that the government-owned Michoud Ordnance Plant near New Orleans, Louisiana, would be the site for fabrication and assembly of the Saturn first stages as well as larger vehicles in the Saturn program. Finalists were two government-owned plants in St. Louis and New Orleans. The height of the factory roof at Michoud meant that a launch vehicle with eight F-1 engines (Saturn C-8, Nova class) could not be built; four or five en ...

Saturn IB
The Saturn IB (also known as the uprated Saturn I) was an American launch vehicle commissioned by the NASA, National Aeronautics and Space Administration (NASA) for the Apollo program. It uprated the Saturn I by replacing the S-IV second stage (, 43,380,000 lb-sec total impulse), with the S-IVB (, 96,000,000 lb-sec total impulse). The S-IB first stage also increased the S-I baseline's thrust from to and propellant load by 3.1%. This increased the Saturn I's low Earth orbit payload capability from to , enough for early flight tests of a half-fueled Apollo command and service module (CSM) or a fully fueled Apollo Lunar Module (LM), before the larger Saturn V needed for lunar flight was ready. By sharing the S-IVB upper stage, the Saturn IB and Saturn V provided a common interface to the Apollo spacecraft. The only major difference was that the S-IVB on the Saturn V burned only part of its propellant to achieve Earth orbit, so it could be restarted for trans-lunar injec ...

S-IB
The S-IB stage was the first stage of the Saturn IB launch vehicle, which was used for Earth orbital missions. It was composed of nine propellant containers, eight fins, a thrust structure assembly, eight H-1 rocket engines, and many other components. It also contained the ODOP transponder. The propellant containers consisted of eight Redstone-derived tanks (four holding liquid oxygen (LOX) and four holding RP-1) clustered around a Jupiter rocket-derived tank containing LOX. The four outboard engines gimballed to steer the rocket in flight, which required a few more engine components. The S-IB burned for nearly 2.5 minutes before separating at an altitude of .

S-IC
The S-IC (pronounced S-one-C) was the first stage of the American Saturn V rocket. The S-IC stage was manufactured by the Boeing Company. Like the first stages of most rockets, most of its mass of more than at launch was propellant, in this case RP-1 rocket fuel and liquid oxygen (LOX) oxidizer. It was tall and in diameter, and provided of thrust to get the rocket through the first of ascent. The stage had five F-1 engines in a quincunx arrangement. The center engine was fixed in position, while the four outer engines could be hydraulically gimballed to control the rocket. Manufacturing The Boeing Co. was awarded the contract to manufacture the S-IC on December 15, 1961. By this time the general design of the stage had been decided on by the engineers at the Marshall Space Flight Center (MSFC). The main place of manufacture was the Michoud Assembly Facility, New Orleans. Wind tunnel testing took place in Seattle and the machining of the tools needed to build the stages at W ...

M46 Patton
The M46 Patton is an American medium tank designed to replace the M26 Pershing and M4 Sherman. It was one of the U.S Army's principal medium tanks of the early Cold War, with models in service from 1949 until the mid-1950s. It was not widely used by U.S. Cold War allies, being exported only to Belgium, and only in small numbers to train crews on the upcoming M47 Patton. The M46 was the first tank to be named after General George S. Patton Jr., commander of the U.S. Third Army during World War II and one of the earliest American advocates for the use of tanks in battle. History After World War II, most U.S. Army armored units were equipped with a mix of M4 Sherman and M26 Pershing tanks. Designed initially as a heavy tank, the M26 Pershing tank was reclassified as a medium tank after the war. The M26 was a significant improvement over the M4 Sherman in firepower and protection. Its mobility, however, was deemed unsatisfactory for a medium tank, as it used the same engine as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M4 Sherman
} The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the Military history of the United States during World War II, United States and Allies of World War II, Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other Armoured_fighting_vehicle, armored fighting vehicles including self-propelled artillery, Tank_destroyer, tank destroyers, and Armoured_recovery_vehicle, armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Empire#Second World War, British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman evolved from the M3 Lee, M3 Medium Tank, which for speed of development had its main armament in a side sponson mount. The M4 retained much of the previous mechanical design, but moved the 75_mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Curtiss C-46 Commando
The Curtiss C-46 Commando is a twin-engine transport aircraft derived from the Curtiss CW-20 pressurised high-altitude airliner design. Early press reports used the name "Condor III" but the Commando name was in use by early 1942 in company publicity. It was used as a military transport during World War II by the United States Army Air Forces and also the U.S. Navy/Marine Corps, which called it R5C. The C-46 served in a similar role to its Douglas-built counterpart, the C-47 Skytrain, but it was not as extensively produced as the latter. After World War II, a few surplus C-46 aircraft were briefly used in their original role as passenger airliners but the glut of surplus C-47s dominated the marketplace and the C-46 was soon relegated to cargo duty. The type continued in U.S. Air Force service in a secondary role until 1968. The C-46 continues in operation as a rugged cargo transport for arctic and remote locations with its service life extended into the 21st century. Design and ...

Landing Craft
Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force (infantry and vehicles) from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States. Because of the need to run up onto a suitable beach, World War II landing craft were flat-bottomed, and many designs had a flat front, often with a lowerable ramp, rather than a normal bow. This made them difficult to control and very uncomfortable in rough seas. The control point (too rudimentary to call a bridge on LCA and similar craft) was normally at the extreme rear of the vessel, as were the engines. In all cases, they were known by an abbreviation derived from the official name rather than by the full title. History In the days of sail, the ship's boats were us ...

Curtiss-Wright C-76 Caravan
The Curtiss-Wright C-76 Caravan (company designation CW-27) was an American all-wood military transport aircraft. The C-76 was intended as a substitute standard aircraft in the event of expected wartime shortages of light alloys.Dreher, Carl, ''Wood Is A War Weapon'', Popular Science, Vol. 141 No.3 (September 1942), pp. 48–74 However, both prototype and production aircraft failed several critical flight and static tests, and after U.S. aluminum production proved sufficient for wartime defense requirements, orders for the C-76 were cancelled and production terminated.Kleber, John E., ''The Encyclopedia of Louisville'', University Press of Kentucky (2001) , , pp. xxvii, 235–236 Design and development In 1941, Curtiss-Wright was contracted by the United States Army Air Forces to design and construct an all-wood military transport aircraft, with performance specifications meeting or exceeding that of the Douglas C-47 Skytrain then in service.Dorrell, David (ed.), ''Curtiss Ca ...
