Some of these include the Grand Slam and T12 earthquake bombs of late World War II, and more currently, the Russian Air Force FOAB and USAF GBU-43/B Massive Ordnance Air Blast bomb, and the Massive Ordnance Penetrator. The fuse itself is a long probe affixed to the weapon's nose, which detonates the bomb if it touches the ground or any solid object. There were 225 constructed.

After the concept proved itself useful it was made famous by being used for the largest conventional bomb in the U.S. military's arsenal at the time, the BLU-82. The welded pipe versions had several adverse effects, such as vibration, pipe weld separation or breakage while in flight, and wind drag, due to impossibility of aligning the pipes correctly with the nose of the weapon, so that phase of development eventually gave way to threaded steel water pipes screwed into the nose cavity of the bombs, leaving only the tail fuse for detonation. Primary aircrew considerations include accurate ballistic and wind computations provided by the navigator, and precision instrument flying with strict adherence to controller instructions. A bomb with a conventional fuse will often be driven deeply into the ground by the force of its impact, limiting the range of its blast. It is one of t…

Sa charge explosive a une puissance équivalente à onze tonnes de TNT et un rayon d'effet de souffle de 150 m. La bombe détone juste avant de heurter le sol, créant une onde de choc destructrice[8]. WDSE WRPT - PBS 72,180 views.

The type depicted in the leaflets, and also used in Afghanistan, is the BLU-82B Commando Vault or Big Blue 82, also known as the Daisy Cutter. This results in a maximum destruction at ground level without digging a crater. C'est la plus puissante bombe non nucléaire de l'arsenal des Forces armées des États-Unis[3]. BLU-82 Daisy Cutter The BLU-82 was a 6800kg bomb originally designed to create jungle clearance during the Vietnam War.

The purpose for a daisy-cutter fuse is primarily to maximize blast damage on the surface of a target. RAF Museum: J.F.C.

A thermobaric weapon, aerosol bomb, or vacuum bomb is a type of explosive that uses oxygen from the surrounding air to generate a high-temperature explosion.

Elle est guidée par GPS[1] et sa trajectoire de chute est contrôlée par une centrale inertielle[7]. Making an FAE the size of a Daisy Cutter would be difficult because the correct uniform mixture of the flammable agent with the ambient air would be difficult to maintain if the agent were so widely dispersed. The BLU-82 was a 6800kg bomb originally designed to create jungle clearance during the Vietnam War.

La MOAB n'est pas la plus lourde bombe existante. The first reference to a "daisy-cutter type of bomb" is found in the memoir of Lieutenant Jack Wilkinson in describing the 1918 attack on the Royal Air Force airfield at Bertangles.
They were used in the Vietnam War for creating instant helicopter landing sites in dense jungle. These weapons were used in the "shock and awe" phase of the Iraq War. [4] The initial drop tested the ability of the bomb to clear or breach mine fields;[5] however, no reliable assessments of mine clearing effectiveness are publicly available. The Air Force could drop a Daisy Cutter to create an instant helicopter landing site.

La MOAB a été testée pour la première fois le 11 mars 2003[12]. The concept for the fuse is attributed to an Air America employee who grasped the idea during a night of drinking. JASSM To Fly With New Explosive Formulation, Ghost Tape No. MOAB is the most powerful conventional bomb in America's arsenal, and is an evolutionary follow-un to the 15,000lb BLU-82 "Daisy Cutters… La GBU-43/B Massive Ordnance Air Blast Bomb (en français : « Bombe à effet de souffle massif »)[2], abrégée par le sigle MOAB, est une bombe guidée à effet de souffle américaine de 10,3 tonnes. D'après des sources officielles afghanes relayées par l'armée américaine, cette frappe aérienne sur Nangarhâr (en) aurait tué 94 militants de l'EI-K dont quatre dirigeants[14].
