The Mark 82 is a 500 pound (227 kg) unguided, low-drag general-purpose bomb, part of the United States Mark 80 series. The explosive filling is usually tritonal, though other compositions have sometimes been used.
With a nominal weight of 500 lb (230 kg), it is one of the smallest bombs in current service, and one of the most common air-dropped weapons in the world. Although the Mk82's nominal weight is 500 lb (230 kg), its actual weight varies depending on its configuration, from 510 to 570 lb (230 to 260 kg). It is a streamlined steel casing containing 192 lb (87 kg) of Tritonal high explosive. The Mk82 is offered with a variety of fin kits, fuzes, and retarders for different purposes.
The Mk82 is the warhead for the GBU-12 laser-guided bombs and for the GBU-38 JDAM.
Currently only the General Dynamics plant in Garland, Texas and Nitro-Chem in Bydgoszcz, Poland are Department of Defense-certified to manufacture bombs for the US Armed Forces.[ citation needed ]
The Mk82 is currently undergoing a minor redesign to allow it to meet the insensitive munitions requirements set by Congress.
According to a test report conducted by the United States Navy's Weapon Systems Explosives Safety Review Board established in the wake of the 1967 USS Forrestal fire, the cooking off time for a Mk82 is approximately 2 minutes30 seconds.
More than 4,500 GBU-12/Mk82 laser-guided bombs were dropped on Iraq during the Persian Gulf War. [7] France requested 1,200 Mk82s in 2010 to Société des Ateliers Mécaniques de Pont-sur-Sambre (SAMP) which builds Mk82s under license. [8] Saudi Arabia requested 8,000 Mk82s in 2015, along with guidance kits and other weapons. [9]
In August, 2018, a Mark 82 bomb was used for the Dahyan air strike. Munitions experts confirmed that the numbers on it identified Lockheed Martin as its maker and that this particular Mk 82 was a Paveway, a laser-guided bomb. [10]
Along with the heavier Mark 84 bombs, Mark 82 bombs were also supplied for the Israel-Hamas war. [11]
In low-level bombing, it is possible for the delivering aircraft to sustain damage from the blast and fragmentation effects of its own munitions since the aircraft and ordnance arrive at the target almost simultaneously. To address this issue, the standard Mk82 General-Purpose bomb can be fitted with a special high-drag tail fin unit. In this configuration, it is referred to as the Mk82 Snake Eye. [12] The tail unit has four folded fins that spring open into a cruciform shape when the bomb is released, slowing the bomb by increasing drag, thus allowing the delivery aircraft to safely pass over the target before the bomb hits it.
A bunker buster is a type of munition that is designed to penetrate hardened targets or targets buried deep underground, such as military bunkers.
The GBU-10 Paveway II is an American Paveway-series laser-guided bomb, based on the Mk 84 general-purpose bomb, but with laser seeking capabilities and wings for guidance. Introduced into service c. 1976, it is used today by USAF, US Navy, US Marine Corps, Royal Australian Air Force and various NATO air forces.
The GBU-12 Paveway II is an American aerial laser-guided bomb, based on the Mk 82 500-pound (227 kg) general-purpose bomb, but with the addition of a nose-mounted laser seeker and fins for guidance. A member of the Paveway series of weapons, Paveway II entered into service c. 1976. It is currently in service with the U.S. Air Force, U.S. Navy, U.S. Marine Corps, and various other air forces.
The GBU-28 is a 4,000-pound (1814.3 kg) 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.
The Mark 84 or BLU-117 is a 2,000-pound (900 kg) 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 to be dropped. At the time, it was the third largest bomb by weight in the US inventory behind the 15,000-pound (6,800 kg) BLU-82 "Daisy Cutter" and the 3,000-pound (1,400 kg) M118 "demolition" bomb. It is currently sixth in size due to the addition of the 5,000 lb (2,300 kg) GBU-28 in 1991, the 22,600 lb (10,300 kg) GBU-43/B Massive Ordnance Air Blast bomb (MOAB) in 2003, and the 30,000 lb (14,000 kg) Massive Ordnance Penetrator.
The Mark 83 is a 1,000 pounds bomb, part of the Mark 80 series of low-drag general-purpose bombs in United States service.
GBU-24 Paveway III or simply GBU-24 is a family of laser-guided bombs, a sub-group of the larger Raytheon Paveway III family of weapons. The Paveway guidance package consists of a seeker package attached to the nose of the weapon, and a wing kit attached to the rear to provide stability and greater range.
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 15 nautical miles (28 km). JDAM-equipped bombs range from 500 to 2,000 pounds. 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 identifier, superseding the Mark 80 or BLU nomenclature of the bomb to which it is attached.
Paveway is a series of laser-guided bombs (LGBs).
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.
The M117 is an air-dropped demolition bomb used by United States military forces. The weapon dates back to the Korean War of the early 1950s. Although it has a nominal weight of 750 pounds (340 kg) its actual weight, depending on fuze and retardation options, can be around 820 pounds (372 kg). The bomb's explosive content is typically 386 pounds (175 kg) of Tritonal or 377 pounds (171 kg) of Minol in the case of the M117A1E2 due to their higher density and detonation velocity compared to TNT. Demolition bombs rely on time delayed fuzes which allow the bomb to burrow into a building or other structure before detonating. The M117 can be configured with a conical low-drag tail for medium and high altitude deliveries or a high-drag tail fin for low-altitude drops, delaying the bombs hitting their targets ensuring bombers are out of the blast zone before detonation. The M117 was the basis for the BOLT-117, the world's first laser-guided bomb.
The Mark 81 is a general-purpose 250-pound (110 kg) bomb. It's the smallest of the Mark 80 series of low-drag general-purpose bombs.
The BLU-109/B is a hardened penetration bomb used by the United States Air Force. As with other "bunker busters", it is intended to penetrate concrete shelters and other hardened structures before exploding. In addition to the US, it is part of the armament of the air forces of Australia, Belgium, Canada, Denmark, France, Germany, Greece, Italy, Israel, Netherlands, Norway, Pakistan, Saudi Arabia, United Kingdom and United Arab Emirates.
The GBU-57A/BMassive Ordnance Penetrator (MOP) is a precision-guided, 30,000-pound (14,000 kg) "bunker buster" bomb used by the United States Air Force. It is substantially larger than the deepest-penetrating bunker busters previously available, the 5,000-pound (2,300 kg) GBU-28 and GBU-37.
Mark 7 "Thor" was the First tactical fission bomb adopted by US armed forces. It was also the first weapon to be delivered using the toss method with the help of the low-altitude bombing system (LABS). The weapon was tested in Operation Buster-Jangle. To facilitate external carry by fighter-bomber aircraft, Mark 7 was fitted with retractable stabilizer fins. The Mark 7 warhead (W7) also formed the basis of the 30.5 inches (775 mm) BOAR rocket, the Mark 90 Betty nuclear depth charge, MGR-1 Honest John rocket, and MGM-5 Corporal ballistic missile. It was also supplied for delivery by Royal Air Force Canberra aircraft assigned to NATO in Germany under the command of SACEUR. This was done under the auspices of Project E, an agreement between the United States and the UK on the RAF carriage of US nuclear weapons. In UK use it was designated 1,650 lb. H.E. M.C. The Mark 7 was in service from 1952 to 1967(8) with 1700–1800 having been built.
A guided bomb is a precision-guided munition designed to achieve a smaller circular error probable (CEP).
The BLU-116 is a United States Air Force bomb, designed as an enhanced bunker buster penetration weapon, designed to penetrate deep into rock or concrete and destroy hard targets.
A precision-guided munition is a guided munition intended to precisely hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the First Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped.
The GBU-39/B Small Diameter Bomb (SDB) is a 250-pound (110 kg) precision-guided glide bomb that is intended to provide aircraft with the ability to carry a higher number of more accurate bombs. Most US Air Force aircraft will be able to carry a pack of four SDBs in place of a single 2,000-pound (910 kg) bomb. It first entered service in 2006. The Ground Launched Small Diameter Bomb (GLSDB) was later developed to enable the SDB to be launched from a variety of ground launchers and configurations.
The M549 is a high-explosive rocket-assisted (HERA) 155 mm howitzer round developed for use by the US military in order to add additional range to standard howitzers, with a maximum range 30.1 km (18.7 mi) from a M198 howitzer. The projectile has two distinctive pre-assembled components—the high explosive (HE) warhead and the rocket motor, making it a form of rocket-assisted projectile. The warhead is fabricated from high fragmentation steel for increased effectiveness in terms of damage caused to target and contains a bulk-filled explosive.
The new arms packages include more than 1,800 MK84 2,000-pound bombs and 500 MK82 500-pound bombs, said the sources, who confirmed a report in the Washington Post.
