Mark 84 Bomb
The Mark 84 or BLU-117 is a American general-purpose bomb, general purpose aircraft 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. At the time, it was the third largest bomb by weight in the US inventory behind the BLU-82 "Daisy Cutter" and the Mark 118 bomb, 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, GBU-57A/B Massive Ordnance Penetrator (MOP). Development and use 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 can form a crater wide and deep. It can penetrate up to of metal or of concrete, depending on the height from which it is dropped, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General-purpose Bomb
A general-purpose bomb is an air-dropped bomb intended as a compromise between blast damage, penetration, and fragmentation in explosive effect. They are designed to be effective against enemy troops, vehicles, and buildings. Characteristics General-purpose (GP) bombs use a thick-walled metal casing with explosive filler (typically TNT, Composition B, or Tritonal in NATO or United States service) comprising about 30% to 40% of the bomb's total weight. The British term for a bomb of this type is "medium case" or "medium capacity" (MC). The GP bomb is a common weapon of fighter bomber and attack aircraft because it is useful for a variety of tactical applications and relatively cheap. General-purpose bombs are often identified by their weight (e.g., ). In many cases this is strictly a ''nominal weight'' (the counterpart to the ''caliber'' of a firearm), and the actual weight of each individual weapon may vary depending on its retardation, fusing, carriage, and guidance syste ...

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] |
Fuze
In military munitions, a fuze (sometimes fuse) is the part of the device that initiates its function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams. A fuze is a device that detonates a munition's explosive material under specified conditions. In addition, a fuze will have safety and arming mechanisms that protect users from premature or accidental detonation. For example, an artillery fuze's battery is activated by the high acceleration of cannon launch, and the fuze must be spinning rapidly before it will function. "Complete bore safety" can be achieved with mechanical shutters that isolate the detonator from the main charge until the shell is fired. A fuze may contain only the electronic or mechanical elements necessary to signal or actuate the detonator, but some fuzes contain a small amount of primary explosive to initiate the deton ...

Massive Ordnance Penetrator
The GBU-57 series MOP (Massive Ordnance Penetrator) is a class, precision-guided munition "bunker buster" bomb developed by Boeing for the United States Air Force (USAF). Composed of a BLU-127 bomb body and an integrated GPS/INS guidance package, there are seven GBU-57 variants. Due to its size and weight, the GBU-57 MOP can only be carried by the Northrop B-2 Spirit strategic bomber, although initial tests were conducted with the Boeing B-52 Stratofortress. The first combat use of the GBU-57 MOP came on 22 June 2025, when seven Northrop B-2 Spirit stealth bombers dropped a total of fourteen GBU-57 bombs on Iran's Fordow Uranium Enrichment Plant and Natanz Nuclear Facility. The bomb is much larger than earlier USAF bunker busters such as the GBU-28 and GBU-37. Development and production Bunker-busting bombs were used in the 2003 invasion of Iraq, but failed to penetrate deeply or achieve the desired destruction. This renewed interest in a larger bunker buster, so the De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GBU-43/B Massive Ordnance Air Blast Bomb
The GBU-43/B Massive Ordnance Air Blast (MOAB, , colloquially explained as "mother of all bombs") is a large-yield bomb, developed for the United States military by Albert L. Weimorts, Jr. of the Air Force Research Laboratory. It was first tested in 2003. At the time of development, it was said to be the most powerful non-nuclear weapon in the American arsenal. The bomb is designed to be delivered by a C-130 Hercules, primarily the MC-130E Combat Talon I or MC-130H Combat Talon II variants. The bomb's name and nickname were inspired by Iraqi president Saddam Hussein's invocation of the "mother of all battles" (''Umm al-Ma'arik'') during the 1991 Gulf War. The MOAB was first deployed in combat on the 13 April 2017 airstrike against an Islamic State – Khorasan Province tunnel complex in Achin District, Afghanistan. Design and development The basic principle resembles that of the BLU-82 ''Daisy Cutter'', which was used to clear heavily wooded areas in the Vietnam War. Deca ...

GBU-28
The GBU-28 (Guided Bomb Unit‐28) is a class laser-guided " bunker busting" bomb produced originally by the Watervliet Arsenal, Watervliet, New York. It was designed, manufactured, and deployed in less than three weeks due to an urgent need during Operation Desert Storm to penetrate hardened Iraqi command centers located deep underground. Only two of the weapons were dropped in Desert Storm, both by F-111Fs. One GBU-28 was dropped during Operation Iraqi Freedom. It was designed by Albert L. Weimorts. The Enhanced GBU-28 augments the laser-guidance with inertial navigation and GPS guidance systems. Design and development In August 1990, the U.S. military began planning an air offensive campaign against Iraq. Planners noticed that a few command and control bunkers in Baghdad were located deep underground to withstand heavy fire. Doubts were raised about the ability of the BLU-109/B to penetrate such fortified structures, so the US Air Force Air Armament Division at Eg ...

Mark 118 Bomb
The M118 is an air-dropped general-purpose or demolition bomb used by United States military forces. It dates back to the time of the Korean War of the early 1950s. Although it has a nominal weight of , its actual weight, depending on fuse and retardation options, is somewhat higher. A typical non-retarded configuration has a total weight of with an explosive content of of tritonal. This is a much higher percentage than in the more recent American Mark 80 series bombs thus the designation as a demolition bomb. In the late 1950s through the early 1970s it was a standard aircraft weapon, carried by the F-100 Super Sabre, F-111 Aardvark, F-104 Starfighter, F-105 Thunderchief, and F-4 Phantom. Some apparently remain in the USAF inventory, although they are rarely used today. It was a component of the GBU-9/B version of the Rockwell electro-optically guided Homing Bomb System (HOBOS). This weapon consisted of an M118 fitted with a KMU-390/B guidance kit with an image contrast se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BLU-82
The BLU-82B/C-130 weapon system, known under program "Commando Vault" and nicknamed " Daisy Cutter" in Vietnam for its ability to flatten a section of forest into a helicopter landing zone, was an American conventional bomb, delivered from either a C-130 or MC-130 transport aircraft or a CH-54 Tarhe heavy-lift helicopter from the 1st Air Cavalry. A total of 225 were constructed. It was successfully used during military operations in Vietnam, the Gulf War and Afghanistan. The BLU-82 was retired in 2008 and replaced with the more powerful GBU-43/B MOAB. Overview The designation "BLU" stands for Bomb Live Unit, as opposed to "BDU" (Bomb Dummy Units) used for practice. Originally designed to create an instant clearing in the jungles of Vietnam, the BLU-82B/C-130 was test-dropped there from a CH-54 Tarhe "Flying crane" helicopter. Later it was used in Afghanistan as an anti-personnel weapon and as an intimidation weapon because of its very large blast radius (variously repor ...
