Laser Guided Bombs
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 of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guided Bombs
A guided bomb (also known as a smart bomb, guided bomb unit, or GBU) is a precision-guided munition designed to achieve a smaller circular error probable (CEP). The creation of precision-guided munitions resulted in the retroactive renaming of older bombs as unguided bombs or "dumb bombs". Guidance Guided bombs carry a guidance system which is usually monitored and controlled from an external device. A guided bomb of a given weight must carry fewer explosives to accommodate the guidance mechanisms. Radio The Germans were first to introduce Precision Guided Munitions (PGMs) in combat, using the 1,400-kg (3,100 lb) MCLOS-guidance Fritz X to successfully attack the Italian battleship ''Roma'' in September 1943. The closest Allied equivalents were the 1,000-lb (454 kg) AZON (AZimuth ONly), used in both Europe and the CBI Theater, and the US Navy's Bat, primarily used in the Pacific Theater of World War II which used autonomous, on-board radar guidance.

Missile Guidance
Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg). These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active", "passive", and "preset" guidance. Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion. History The concept of unmanned guidance originated at least as early as World War I, with the idea of remotely guiding an airplane bomb onto a target, such as the systems developed for the R.F.C. World War I Drone Weapons, first powered drones by Archibald Low (The Father of Radio Guidance). In World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

KAB-500L
The KAB-500L is a laser-guided bomb developed by the Soviet Air Force, entering service in 1975. It remains in service with the CIS and post-Soviet Russian Air Force. The KAB-500L is a standard FAB-500 general-purpose bomb, which has a nominal weight of , fitted with a semi-active laser seeker and guidance fins, turning it into an unpowered guided bomb. The KAB-500L is long and weighs . Its warhead makes up of the total weight, of which roughly 50% is blast-effect high explosive. Russian sources credit it with a CEP of . The technology of KAB-500L is also used for larger bombs, such as the KAB-1500L family. It is also deployed by the Indian Air Force. The primary launch platform is Su-30MKI. This bomb is also used by Royal Malaysian Air Force on its Sukhoi Su-30MKM. KAB-500S-E KAB-500S-E is a Precision-Guided Munition (PGM) whose guidance system is based on GLONASS. The weapon can be dropped from aircraft flying at an altitude from 500 meters to 5000 meters and with an air ... [...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 ...

Bombe Guidée Laser
Bombe Guidée Laser (BGL) laser-guided bombs were developed by Matra (now MBDA) starting in 1978. The guidance system had to work using the same principles as the US Paveway guided bombs. The guidance kits were intended as modifications to existing free fall bombs that were in service with the French Air Force. The semi active laser homing (SALH) guidance system was developed starting from the AS-30 laser-guided missile sensor. The guidance system allowed for in-flight target illumination by the aircraft-mounted ATLIS 2 (Automatic Tracking Laser Illumination System) or with ground-based laser designator targeting pod. The BGL targeting system are attached to 250, 400 and 1,000 kg free-fall general-purpose bombs. The French Air Force discontinued the purchases due to the higher cost compared to the US Paveway family bombs that were adopted as an interim solution while waiting for the French-made AASM AASM may refer to: * Armement Air-Sol Modulaire, a French precision guided mun ...

Inertial Navigation System
An inertial navigation system (INS) is a navigation device that uses motion sensors (accelerometers), rotation sensors ( gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references. Often the inertial sensors are supplemented by a barometric altimeter and sometimes by magnetic sensors ( magnetometers) and/or speed measuring devices. INSs are used on mobile robots and on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft. Other terms used to refer to inertial navigation systems or closely related devices include inertial guidance system, inertial instrument, inertial measurement unit (IMU) and many other variations. Older INS systems generally used an inertial platform as their mounting point to the vehicle and the terms are sometimes considered synonymous. Overview Inertial navigation is a self-cont ...

Sudarshan Laser-guided Bomb
Sudarshan (Hindi: सुदर्शन, "good-looking", also Krishna's Chakra) is an Indian laser-guided bomb kit, developed by Aeronautical Development Establishment (ADE), a DRDO lab with technological support from another DRDO lab Instruments Research and Development Establishment (IRDE), for the Indian Air Force (IAF). Background Laser guided bombs were first developed by United States in 1960s. Later, Russia, France, and Britain also developed them. Laser-guided bombs are called "smart bombs" because they can follow a non-ballistic trajectory when laser designation of the intended target is done. A laser-guided bomb can hit its target with greater accuracy that ordinary dumb bombs. LGBs are manoeuvrable, free-fall weapons requiring no electronic interconnection to the aircraft. The bomb, once released by the aircraft, will seek the target and glide towards it using laser beam riding. The Sudarshan is India's first indigenous laser-guided bomb kit. It is designed to improve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
