Mark 83
The Mark 83 is a bomb, part of the Mark 80 series of low-drag general-purpose bombs in United States service. Development and deployment The nominal weight of the bomb is , although its actual weight varies between and , depending on fuze options, and fin configuration. The Mk 83 is a streamlined steel casing containing of tritonal high explosive. When filled with PBXN-109 thermally insensitive explosive, the bomb is designated BLU-110. The Mk 83/BLU-110 is used as the warhead for a variety of precision-guided weapons, including the GBU-16 Paveway laser-guided bombs, the GBU-32 JDAM and Quickstrike sea mines. The Mk 83 is also used as the warhead in a variety of Pakistani smart bombs made by GIDS.

Tritonal
Tritonal is a mixture of 80% TNT and 20% aluminium powder, used in several types of ordnance such as air-dropped bombs. The aluminium increases the total heat output and hence impulse of the TNT – the length of time during which the blast wave is positive. Tritonal is approximately 18% more powerful than TNT alone. The 87 kg of tritonal in a Mark 82 bomb has the potential to produce approximately 863 MJ of energy when detonated. This implies a specific energy of approximately 9 MJ/kg, compared to ~4 MJ/kg for TNT. History TNT was first prepared by Julius Wilbrand in 1863. Germany began manufacturing TNT in 1891 and aluminium was first mixed with TNT in 1899 to produce an explosive compound. In 1902, the German Army began to use TNT, replacing picric acid, and in 1912, the US Army also started to use TNT. TNT production was limited by the availability of toluene which came from coal tar. Therefore, mixtures of TNT with other compounds became w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smart Bombs
A guided bomb (also known as a smart bomb, guided bomb unit, or GBU) is a precision-guided munition designed to achieve a smaller circular error probable (CEP). The creation of precision-guided munitions resulted in the retroactive renaming of older bombs as unguided bombs or "dumb bombs". Guidance Guided bombs carry a guidance system which is usually monitored and controlled from an external device. A guided bomb of a given weight must carry fewer explosives to accommodate the guidance mechanisms. Radio The Germans were first to introduce precision guided munitions (PGMs) in combat, using the 1,400-kg (3,100 lb) MCLOS-guidance Fritz X to successfully attack the Italian battleship ''Roma'' in September 1943. The closest Allied equivalents were the 1,000-lb (454 kg) AZON (AZimuth ONly), used in both Europe and the CBI Theater, and the US Navy's Bat, primarily used in the Pacific Theater of World War II which used autonomous, on-board radar guidance.

Mark 81 Bomb
The Mark 81 is a general-purpose bomb (nicknamed "Firecracker"). It's the smallest of the General-purpose bomb#Modern American GP bombs: the Mark 80 series, Mark 80 series of low-drag (physics), drag general-purpose bombs. Development and deployment Developed for United States military forces in the 1950s, it was first used during the Vietnam War. The bomb consists of a forged steel case with of Composition H6, Minol (explosive), Minol or Tritonal explosive. The power of the Mk 81 was found to be inadequate for U.S. military tactical use, and it was quickly discontinued, although license-built copies or duplicates of this weapon remain in service with various other nations. Development of a precision guided variant of the Mk 81 bomb (GBU-29) was started due to its potential to reduce collateral damage compared to larger bombs, but this program has now been cancelled in favor of the Small Diameter Bomb.

Cooking Off
Cooking off (or thermally induced firing) is unfired weapon ammunition explosion, exploding prematurely due to heat in the surrounding environment. The term is used both for detonation of ammunition not loaded into a weapon, and unintended firing of a loaded weapon due to heating. A fast cook-off is a cook-off caused by fire. A slow cook-off is caused by a sustained thermal event less intense than fire. A cooked-off round may cause a sympathetic detonation of adjacent rounds. Insensitive munitions are designed to be less vulnerable to accidental firing induced by external heat. Artillery Inherent design flaws in early 17th century Sweden, Swedish leather cannons led to the gun barrel, gun tube overheating which prematurely ignited the gunpowder, injuring the loader. Muzzle-loading cannon on merchant and naval vessels of the Age of Sail would fire if the vessels caught fire while the guns were loaded. Examples include the merchantman and . After the cooking off of artillery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1967 USS Forrestal Fire
On 29 July 1967, a fire broke out on board the aircraft carrier USS ''Forrestal'' after an electrical anomaly caused a Zuni rocket on an F-4B Phantom to fire, striking an external fuel tank of an A-4 Skyhawk. The flammable jet fuel spilled across the flight deck, ignited, and triggered a chain reaction of explosions that killed 134 sailors and injured 161. At the time, ''Forrestal'' was engaged in combat operations in the Gulf of Tonkin, during the Vietnam War. The ship survived, but with damage exceeding US$72 million, not including the damage to aircraft. Future United States Senator John McCain and future four-star admiral and U.S. Pacific Fleet Commander Ronald J. Zlatoper were among the survivors. Another on-board officer, Lieutenant Tom Treanore, later returned to the ship as her commander and retired an admiral. The incident was the second of three serious fires to strike American carriers in the 1960s. A 1966 fire aboard USS ''Oriskany'' killed 44 and injured 138 ...

Weapon System Safety
The system safety concept calls for a risk management strategy based on identification, analysis of hazards and application of remedial controls using a systems-based approach. This is different from traditional safety strategies which rely on control of conditions and causes of an accident based either on the epidemiological analysis or as a result of investigation of individual past accidents. The concept of system safety is useful in demonstrating adequacy of technologies when difficulties are faced with probabilistic risk analysis. The underlying principle is one of synergy: a whole is more than sum of its parts. Systems-based approach to safety requires the application of scientific, technical and managerial skills to hazard identification, hazard analysis, and elimination, control, or management of hazards throughout the life-cycle of a system, program, project or an activity or a product. "Hazop" is one of several techniques available for identification of hazards. System a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Direct Attack Munition
The Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs, or "dumb bombs", into all-weather precision-guided munitions (PGMs). JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to . JDAM-equipped bombs range from . The JDAM's guidance system was jointly developed by the United States Air Force and United States Navy, hence the "joint" in JDAM. When installed on a bomb, the JDAM kit is given a GBU (Guided Bomb Unit) identifier, superseding the Mark 80 or BLU (Bomb, Live Unit) nomenclature of the bomb to which it is attached. The JDAM is not a stand-alone weapon; rather it is a "bolt-on" guidance package that converts unguided gravity bombs into PGMs. The key components of the system are a tail section with aerodynamic control surfaces, a (body) strake kit, and a combined inertial guidance system and GPS guidance control unit. The JDAM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
