1965 Searcy Missile Silo Fire
The 1965 Searcy missile silo fire was an uncontrolled fire inside a Titan II missile silo near Searcy, Arkansas on August 9, 1965. The fire broke out while the missile silo was being renovated and improved; the missile was installed and fueled at the time, although the nuclear warhead had been removed.Eric Schlosser, "Command and Control." London: Penguin Books, 2014. Only two of the 55 workers who were inside the silo at the time survived. Description Missile silo 373-4 was one of 18 Titan II nuclear missile launch silos in Arkansas, located north of Searcy. The nine-story underground silo was completed on July 31, 1962 and brought online on May 16, 1963. In addition to the silo itself, the launch site included an underground command center connected to the silo by a passageway on underground level 2. In August 1965, non-military contractors were strengthening the silo against potential nuclear attack as part of a broader initiative called Project Yard Fence. As a part of thi ...

Intercontinental Ballistic Missile
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1980 Damascus Titan Missile Explosion
The Damascus Titan missile explosion (also called the Damascus accident) was a 1980 U.S. nuclear weapons incident involving a Titan II Intercontinental Ballistic Missile (ICBM). The incident occurred on September 18–19, 1980, at Missile Complex 374-7 in rural Arkansas when a U.S. Air Force LGM-25C Titan II ICBM loaded with a 9 megaton W-53 Nuclear Warhead had a liquid fuel explosion inside its silo. The incident began with a fuel leak at on September 18, and culminated with the explosion at around on September 19, ejecting the warhead from its silo. The warhead landed a short distance away and no radioactive material was lost. Launch complex Launch Complex 374-7 was located in Bradley Township, Van Buren County farmland just 3.3 miles (5.3 km) NNE of Damascus, and approximately north of Little Rock. The Strategic Air Command facility of Little Rock Air Force Base was one of eighteen silos in the command of the 308th Strategic Missile Wing (308th SMW), spec ...

Fires In Arkansas
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and property, atmospheric pollution, and water contamination. If fire re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Missile Launch Facility
A missile launch facility, also known as an underground missile silo, launch facility (LF), or nuclear silo, is a vertical cylindrical structure constructed underground, for the storage and launching of intercontinental ballistic missiles (ICBMs), intermediate-range ballistic missiles (IRBMs), medium-range ballistic missiles (MRBMs). Similar facilities can be used for anti-ballistic missiles (ABMs). The structures typically have the missile some distance below ground, protected by a large "blast door" on top. They are usually connected, physically and/or electronically, to a missile launch control center. With the introduction of the Soviet UR-100 and the U.S. Titan II missile series, underground silos changed in the 1960s. Both missile series introduced the use of hypergolic propellant, which could be stored in the missiles, allowing for rapid launches. Both countries' liquid-fueled missile systems were moved into underground silos. The introduction of solid fuel systems, in th ...
