1968 Kadena Air Base B-52 Crash
On 19 November 1968, a B-52 crashed at Kadena Air Base, on the island of Okinawa, Japan. Aborted takeoff The United States Air Force (USAF) Strategic Air Command (SAC) B-52D Stratofortress (serial number 55-0103) of the 4252d Strategic Wing had a full bomb load and broke up and caught fire after the aircraft aborted takeoff at Kadena Air Base while it was conducting an Operation Arc Light bombing mission to South Vietnam during the Vietnam War. Resultant fire and explosion The fire resulting from the aborted takeoff ignited the aircraft's fuel and detonated the bomb load of twenty-four bombs, (twelve under each wing) and forty two bombs inside the bomb bay and caused a blast so powerful that it created an immense crater under the burning aircraft some deep and across. The blast blew out the windows in the dispensary at Naha Air Base (now Naha Airport), away and damaged 139 houses. Recovery and investigation The aircraft was reduced "to a black spot on the runway" The bla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kadena Air Base
(IATA: DNA, ICAO: RODN) is a highly strategic United States Air Force base in the towns of Kadena and Chatan and the city of Okinawa, in Okinawa Prefecture, Japan. It is often referred to as the "Keystone of the Pacific" because of its highly strategic and geographic location. It is located just 650 km off the coast of China and at a distance of just 770 km from Shanghai, a major economic hub. It is home to the USAF's 18th Wing, the 353rd Special Operations Group, reconnaissance units, 1st Battalion, 1st Air Defense Artillery Regiment, and a variety of associated units. Over 20,000 American servicemembers, family members, and Japanese employees live or work aboard Kadena Air Base. It is the largest and most active U.S. Air Force base in East Asia. History Kadena Air Base's history dates back to just before the Battle of Okinawa in April 1945, when a local construction firm completed a small airfield named Yara Hikojo near the village of Kadena. The airfield, used by the Im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Entendre
A double entendre (plural double entendres) is a figure of speech or a particular way of wording that is devised to have a double meaning, of which one is typically obvious, whereas the other often conveys a message that would be too socially awkward, sexually suggestive, or offensive to state directly. A double entendre may exploit puns or word play to convey the second meaning. Double entendres generally rely on multiple meanings of words, or different interpretations of the same primary meaning. They often exploit ambiguity and may be used to introduce it deliberately in a text. Sometimes a homophone can be used as a pun. When three or more meanings have been constructed, this is known as a "triple entendre", etc. Etymology According to the Merriam-Webster Unabridged Dictionary and the Oxford English Dictionary, the expression comes from the rare and obsolete French expression, which literally meant "double meaning" and was used in the senses of "double understanding ...

Project 112
Project 112 was a biological and chemical weapon experimentation project conducted by the United States Department of Defense from 1962 to 1973. The project started under John F. Kennedy's administration, and was authorized by his Secretary of Defense Robert McNamara, as part of a total review of the US military. The name "Project 112" refers to this project's number in the 150 project review process authorized by McNamara. Funding and staff were contributed by every branch of the U.S. armed services and intelligence agencies—a euphemism for the Office of Technical Services of the Central Intelligence Agency's Directorate of Science & Technology. Canada and the United Kingdom also participated in some Project 112 activities. Project 112 primarily concerned the use of aerosols to disseminate biological and chemical agents that could produce "controlled temporary incapacitation" (CTI). The test program would be conducted on a large scale at "extracontinental test sites" i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Weapons
A chemical weapon (CW) is a specialized Ammunition, munition that uses chemicals chemical engineering, formulated to inflict death or harm on humans. According to the Organisation for the Prohibition of Chemical Weapons (OPCW), this can be any chemical compound intended as a weapon "or its Precursor (chemistry), precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action. Munitions or other delivery devices designed to deliver chemical weapons, whether filled or unfilled, are also considered weapons themselves." Chemical weapons are classified as weapons of mass destruction (WMD), though they are distinct from nuclear weapons, biological warfare, biological weapons, and radiological weapons. All may be used in warfare and are known by the military acronym NBC (for nuclear, biological, and chemical warfare). Weapons of mass destruction are distinct from conventional weapons, which are primarily effective due to their explos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Red Hat
Operation Red Hat was a United States Department of Defense movement of chemical warfare munitions from Okinawa, Japan to Johnston Atoll in the North Pacific Ocean, which occurred in 1971. Background U.S. chemical weapons were brought into Okinawa in 1962 based on the recommendation of Secretary of Defense Robert McNamara, according to declassified documents. In 1970, U.S. Defense Secretary Melvin Laird met Japan Defense Agency chief Yasuhiro Nakasone, and said that the United States had received information that North Korea had a supply of chemical weapons. The move of U.S. chemical weapons to Okinawa in 1962 was meant to serve as a deterrent. The Red Hat code name was assigned by the Assistant Chief of Staff for Intelligence, Department of the Army, on November 12, 1962, during the planning to deploy chemical agents to the 267th Chemical Platoon on Okinawa. The 267th Chemical Platoon (Service) was activated on Okinawa on December 1, 1962 at Chibana Ammunition Depot. The depot wa ...

MIM-14 Nike-Hercules
The Nike Hercules, initially designated SAM-A-25 and later MIM-14, was a surface-to-air missile (SAM) used by U.S. and NATO armed forces for medium- and high-altitude long-range air defense. It was normally armed with the W31 nuclear warhead, but could also be fitted with a conventional warhead for export use. Its warhead also allowed it to be used in a secondary surface-to-surface role, and the system also demonstrated its ability to hit other short-range missiles in flight. Hercules was originally developed as a simple upgrade to the earlier MIM-3 Nike Ajax, allowing it to carry a nuclear warhead in order to defeat entire formations of high-altitude supersonic targets. It evolved into a much larger missile with two solid fuel stages that provided three times the range of the Ajax. Deployment began in 1958, initially at new bases, but it eventually took over many Ajax bases as well. At its peak, it was deployed at over 130 bases in the US alone. Hercules was officially referred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MGR-1 Honest John
The MGR-1 Honest John rocket was the first nuclear-capable surface-to-surface rocket in the United States arsenal.The first nuclear-authorized ''guided'' missile was the MGM-5 Corporal. Originally designated Artillery Rocket XM31, the first unit was tested on 29 June 1951, with the first production rounds delivered in January 1953. Its designation was changed to M31 in September 1953. The first Army units received their rockets by year's end and Honest John battalions were deployed in Europe in early 1954. Alternatively, the rocket was capable of carrying an ordinary high-explosive warhead weighing . History and development Developed at Redstone Arsenal, Alabama, the Honest John was a large but simple fin-stabilized, unguided artillery rocket weighing in its initial M31 nuclear-armed version. Mounted on the back of a truck, the rocket was aimed in much the same way as a cannon and then fired up an elevated ramp, igniting four small spin rockets as it cleared the end of the ...

MGM-13 Mace
The Martin Mace was a ground-launched cruise missile developed from the earlier Martin TM-61 Matador. It used a new self-contained navigation system that eliminated the need to get updates from ground-based radio stations, and thereby allowed it to fly further beyond the front lines. To take advantage of this longer practical range, Mace was larger than Matador and could travel a longer total distance. The original A model used a ground-mapping radar system which required the missile to fly at low to medium altitudes. In 1959 a new inertial navigation system was introduced that offered similar accuracy but had no altitude limitation. By flying at higher altitudes the missile's range almost doubled with no other changes. This led to the B model of 1961, which was limited to fixed launching sites, unlike the A model's mobile trailers. Mace was replaced by the MGM-31 Pershing missile by then Secretary of Defence Robert McNamara, and later in its role as a cruise missile for West ...

Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: * Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. ***Blast: A strong shock wave is provided by the detonation of the explosive. *** Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. *** Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag-shape ...
