VB-3 Razon
The VB-3 Razon was a high-angle freefall guided bomb developed by the United States Army Air Force during the 1940s. Razon (for Range and AZimuth Only) was a standard AN-M65 1,000-pound general-purpose bomb, the same basic ordnance unit used for its AZimuth-ONly guided predecessor, the VB-1 Azon guided ordnance, with the Razon concept fitted with flight control surfaces that also enabled adjustment in the vertical plane, like the Luftwaffe's heavier Fritz X armored anti-ship guided ordnance. Development of the Razon began in 1942, but it did not see use during World War II although it was combat ready in the summer of 1945. The VB-4 used a 2,000-pound bomb.

Air Technical Service Command
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in ...

ASM-A-1 Tarzon
The ASM-A-1 Tarzon, also known as VB-13, was a guided bomb developed by the United States Army Air Forces during the late 1940s. Mating the guidance system of the earlier VB-3 Razon, Razon radio-controlled weapon with a British Tallboy (bomb), Tallboy bomb, the ASM-A-1 saw brief operational service in the Korean War before being withdrawn from service in 1951. Design and development Development of the VB-13 Tarzon began in February 1945, with Bell Aircraft being awarded a contract by the United States Army Air Forces for the development of a very large guided bomb.Parsch 2003Stumpf 1998, p.13. The VB-13 was a combination of a radio-command guidance system as used on the smaller VB-3 Razon ('Range And azimuth only') guided bomb with the British-developed Tallboy "earthquake" bomb,Schmitt 2002, p.45. known to the USAAF as M112.Gillespie 2006, p.54.

1st Experimental Guided Missiles Group
The 1st Experimental Guided Missiles Group is an inactive United States Air Force unit. It was last assigned to the Air Proving Ground Command and stationed at Eglin Air Force Base, Florida. It was inactivated on 22 July 1949. The 1st EGMG was the initial United States Army Air Forces (later United States Air Force) dedicated missile unit. History Formed a result of the Air Materiel Command's Engineering Division at Wright-Patterson Air Force Base looking for a location to allow its contractors to launch missiles.Mindling and Bolton (2009), U.S. Air Force Tactical Missiles, Missile technologies Initial mission of unit was to determine Air Force missile requirements and review missile propulsion, guidance, and launching technologies. Also matrixed contractors to technologies: * The Glenn L. Martin Company became the primary contractor in short-range, surface-to-surface missiles (e.g., the MX-771 Matador) * Boeing got the surface-to-air business with the MX-606 Bomarc inte ...

Tallboy Bomb
Tallboy or Bomb, Medium Capacity, 12,000 lb was an earthquake bomb developed by the British aeronautical engineer Barnes Wallis and used by the Royal Air Force (RAF) during the Second World War."Medium capacity" refers to the ratio of bomb case to explosive filling; in the case of the Tallboy, this was less than 50 per cent explosive by weight, in contrast to "high capacity" bombs like the Blockbuster bombs, in which up to three-quarters of their weight was the explosive. At , it could be carried only by a modified model of the Avro Lancaster heavy bomber. It proved to be effective against large, fortified structures against which conventional bombing had proved ineffective. History Wallis presented his ideas for a 10-ton bomb in his 1941 paper "A Note on a Method of Attacking the Axis Powers", which showed that a very large bomb exploding deep underground next to a target would transmit the shock into the foundations of the target, particularly since shock waves are tra ...

Mojave Desert
The Mojave Desert ( ; mov, Hayikwiir Mat'aar; es, Desierto de Mojave) is a desert in the rain shadow of the Sierra Nevada mountains in the Southwestern United States. It is named for the indigenous Mojave people. It is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah. The Mojave Desert, together with the Sonoran, Chihuahuan, and Great Basin deserts, forms a larger North American Desert. Of these, the Mojave is the smallest and driest. The Mojave Desert displays typical basin and range topography, generally having a pattern of a series of parallel mountain ranges and valleys. It is also the site of Death Valley, which is the lowest elevation in North America. The Mojave Desert is often colloquially called the "high desert", as most of it lies between . It supports a diversity of flora and fauna. The desert supports a number of human activities, including recreation, ranching, and military training ...

Air Materiel Command
Air Materiel Command (AMC) was a United States Army Air Forces and United States Air Force command. Its headquarters was located at Wright-Patterson Air Force Base, Ohio. In 1961, the command was redesignated the Air Force Logistics Command with some of its functions transferred to the new Air Force Systems Command. History The logistics function can be traced before the earliest days of the Air Service, when the Equipment Division of the U.S. Army Signal Corps established a headquarters for its new Airplane Engineering Department at McCook Field, Dayton, Ohio. Airplane Engineering Department The Airplane Engineering Department was established by the Equipment Division of the U.S. Army Signal Corps in 1917 for World War I experimental engineering. The department had a 1917 Foreign Data Section, and the Airplane Engineering Department was on McCook Field at Dayton, Ohio. McCook Field established the Air School of Application in 1919 and after WW I, the department was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
