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 (from "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
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage. The current composition o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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with a British Tallboy (bomb), Tallboy bomb, the ASM-A-1 saw brief operational service in the Korean War before being withdrawn from service in 1951.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 int ...

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 where 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 transmitted ...
