Mk 84
The Mark 84 or BLU-117 is an American general-purpose bomb. It is the largest of the Mark 80 series of weapons. Entering service during the Vietnam War, it became a commonly used US heavy unguided bomb (due to the amount of high-explosive content packed inside) to be dropped. At the time, it was the third largest bomb by weight in the US inventory behind the BLU-82 "Daisy Cutter" and the M118 "demolition" bomb. It is currently sixth in size due to the addition of the GBU-28 in 1991, the GBU-43/B Massive Ordnance Air Blast bomb (MOAB) in 2003, and the Massive Ordnance Penetrator. Development The Mark 84 has a nominal weight of , but its actual weight varies depending on its fin, fuze options, and retardation configuration, from . It is a streamlined steel casing filled with of Tritonal high explosive. The Mark 84 is capable of forming a crater wide and deep.

Cooking Off
Cooking off (or thermally induced firing) is unfired weapon ammunition 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 Swedish leather cannons led to the 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 shells in the G5 howitzer ... [...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 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 its commander and retired an admiral. The disaster prompted the Navy to revise its fire fighting practices. It also modified its weapon handling procedures and installed a deck wash down system on all carriers. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weapon System Safety
The United States Navy formed the Weapon System Explosives Safety Review Board (WSESRB) in 1968 as a result of the tragic fire Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. At a certain point in the combustion reaction, called the ignition ... on the USS ''Forrestal'' (CV-59). The subsequent investigation recommended an independent review process be established. The report highlighted the need to ensure explosives safety requirements are met for all munitions introduced to the Fleet. As a result, the WSESRB was established. WSESRB participate in numerous weapons system safety-related meetings, technical reviews, and working groups. The US Air Force and US Army have parallel boards to the Navy's WSESRB: the AF Nonnuclear Munitions Safety Board (NNMSB) and the Army Weapon Systems Safety Review Board (AWSSRB) Areas reviewed by weapon boards incl ...

Sea Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individuals ...

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. 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 precision-guided munitions (PGMs). The key components of the system consist of a tail section with aerodynamic control surfaces, a (body) Strake (aeronautics), strake kit, and a combined inertial guidance s ...

Laser-guided Bomb
A laser-guided bomb (LGB) is a guided bomb that uses semi-active laser guidance to strike a designated target with greater accuracy than an unguided bomb. First developed by the United States during the Vietnam War, laser-guided bombs quickly proved their value in precision strikes of difficult point targets. These weapons use on-board electronics to track targets that are designated by laser, typically in the infrared spectrum, and adjust their glide path to accurately strike the target. Since the weapon is tracking a light signature, not the object itself, the target must be illuminated from a separate source, either by ground forces, by a pod on the attacking aircraft, or by a separate support aircraft. Data from the 28,000 laser guided bombs dropped in Vietnam showed that laser-guided bombs achieved direct hits nearly 50% of the time, despite the laser having to be aimed out the side window of the back seat of another aircraft in flight. Unguided bombs had an accuracy rate o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
