BLU-116
The BLU-116 is a United States Air Force Gravity bomb, bomb, designed as an enhanced bunker buster penetration weapon, designed to penetrate deep into rock or concrete and destroy hard targets.BLU-116 Advanced Unitary Penetrator (AUP) GBU-24 C/B (USAF) / GBU-24 D/B (Navy) accessed Oct 2, 2007 The BLU-116 is the same shape, size, and weight (1,927 lb / 874 kg) and twice the penetration as the BLU-109 penetration bomb first deployed in the 1980s. The BLU-116 has a lightweight outer shell around a dense, heavy metal penetrator core. The shape and size mean that the BLU-116 could be used by unmodified existing aircraft and bomb guidance units such as the GPS guided Joint Direct Attack Munition, GBU-31 Joint Direct Attack Munition an ...

BLU-109
The BLU-109/B is a hardened penetration bomb used by the United States Air Force (BLU is an acronym for Bomb Live Unit). 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. Design The BLU-109/B has a steel casing about thick, filled with of Tritonal. It has a delayed-action tail- fuze. The BLU-109 entered service in 1985. It is also used as the warhead of some marks of the GBU-15 electro-optically guided bomb, the GBU-27 Paveway III laser-guided bomb, and the AGM-130 rocket-boosted weapon. This weapon can penetrate of reinforced concrete, which is greater than the capability of the Small Diameter Bomb. Variants The BLU-118 is reportedly a thermobaric explosive filler ...

Bunker Buster
A bunker buster is a type of munition that is designed to penetrate hardened targets or targets buried deep underground, such as military bunkers. Armor piercing shells Germany Röchling shells were bunker-busting artillery shells, developed by the German engineer August Cönders, based on the theory of increasing sectional density to improve penetration. They were tested in 1942 and 1943 against the Belgian Fort d'Aubin-Neufchâteau. Aircraft delivered bombs World War II Germany In World War II the Luftwaffe developed a series of unguided rocket-propelled armor-piercing bombs for use against shipping and fortifications. United Kingdom In World War II, the British designer Barnes Wallis, already famous for inventing the bouncing bomb, designed two bombs that would become the conceptual predecessors of modern bunker busters: the five tonne Tallboy and the ten tonne Grand Slam. These were "Earthquake" bombs—a concept he had first proposed in 1939. The designs were ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GBU-24 Paveway III
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. Warhead options consist of: * Mk. 84 – General Purpose * BLU-109 – Penetrator * BLU-116 – Advanced Unitary Penetrator * CPE-800 – Used in the BPG-2000, a similar, indigenous Spanish weapon Compared to the GBU-10 family, or the Paveway II family, the GBU-24 glides farther as a result of more efficient guidance technology. The Paveway III guidance kit is more expensive, however, making the GBU-24 suitable against well-defended, high-value targets. It was introduced into service c. 1983. This weapon is in service with the USAF, US Navy, US Marine Corps, and various NATO air forces. The bomb requires a spot of pulse-coded laser energy to home on; this can be supplied by ...

United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravity Bomb
An unguided bomb, also known as a free-fall bomb, gravity bomb, dumb bomb, or iron bomb, is a conventional or nuclear aircraft-delivered bomb that does not contain a guidance system and hence simply follows a ballistic trajectory. This described all aircraft bombs in general service until the latter half of World War II, and the vast majority until the late 1980s. Then, with the dramatically increased use of precision-guided munitions, a retronym was needed to separate "smart bombs" from free-fall bombs. "Dumb bomb" was used for a time, but many military circles felt it sounded too trite, and eventually "gravity bomb" gained popularity. Bomb casings for unguided bombs are typically aerodynamic in shape, often with fins at the tail section, which reduce drag and increase stability after release, both of which serve to improve accuracy and consistency of trajectory. Unguided bombs typically use a contact fuze for detonation upon impact, or some milliseconds after if a penetration ... [...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. 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] |
Polymer-bonded Explosive
Polymer-bonded explosives, also called PBX or plastic-bonded explosives, are explosive materials in which explosive powder is bound together in a matrix using small quantities (typically 5–10% by weight) of a synthetic polymer. PBXs are normally used for explosive materials that are not easily melted into a casting, or are otherwise difficult to form. PBX was first developed in 1952 at Los Alamos National Laboratory, as RDX embedded in polystyrene with dioctyl phthalate plasticizer. HMX compositions with teflon-based binders were developed in 1960s and 1970s for gun shells and for Apollo Lunar Surface Experiments Package (ALSEP) seismic experiments, although the latter experiments are usually cited as using hexanitrostilbene (HNS). Potential advantages Polymer-bonded explosives have several potential advantages: * If the polymer matrix is an elastomer (rubbery material), it tends to absorb shocks, making the PBX very insensitive to accidental detonation, and thus ideal for ...
