A glide bomb or stand-off bomb is a standoff weapon with flight control surfaces to give it a flatter, gliding flight path than that of a conventional bomb without such surfaces. This allows it to be released at a distance from the target rather than right over it, allowing a successful attack without exposing the launching aircraft to anti-aircraft defenses near the target. Glide bombs can accurately deliver warheads in a manner comparable to cruise missiles at a fraction of the cost—sometimes by installing flight control kits on simple unguided bombs—and they are very difficult for surface-to-air missiles to intercept due to their tiny radar signatures and short flight times. The only effective countermeasure in most cases is to shoot down enemy aircraft before they approach within launching range, making glide bombs very potent weapons where wartime exigencies prevent this.
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.
Fritz X was a German guided anti-ship glide bomb used during World War II. Fritz X was the world's first precision guided weapon deployed in combat and the first to sink a ship in combat. Fritz X was a nickname used both by Allied and Luftwaffe personnel. Alternative names include Ruhrstahl SD 1400 X, Kramer X-1, PC 1400X or FX 1400.
The Kawasaki Ki-100 (キ100) is a single-seat single-engine monoplane fighter aircraft used by the Imperial Japanese Army Air Service (IJAAS) during World War II. The Japanese Army designation was "Type 5 Fighter". It was not assigned an Allied code name.
The Mitsubishi Ki-67Hiryū was a twin-engine bomber produced by Mitsubishi Aircraft Company and used by the Imperial Japanese Army Air Service and Imperial Japanese Navy Air Service in World War II. While its original official designation was "Army Type 4 Heavy Bomber", in all of its key parameters, the Ki-67 was similar to the contemporaneous medium bombers of other countries. Japanese Navy variants included the P2M and Q2M.
The Texas Instruments BOLT-117, retrospectively redesignated as the GBU-1/B was the world's first laser-guided bomb (LGB). It consisted of a standard M117 750-pound (340 kg) bomb case with a KMU-342 laser guidance and control kit. This consisted of a gimballed laser seeker on the front of the bomb and tail and control fins to guide the bomb to the target. The latter used the bang-bang method of control where each control surface was either straight or fully deflected. This was inefficient aerodynamically, but reduced costs and minimized demands on the primitive onboard electronics.
AZON, from "azimuth only", was one of the world's first guided weapons, deployed by the Allies and contemporary with the German Fritz X.
The ASM-N-2 Bat was a United States Navy World War II radar-guided glide bomb which was used in combat beginning in April 1945. It was developed and overseen by a unit within the National Bureau of Standards with assistance from the Navy's Bureau of Ordnance, the Massachusetts Institute of Technology, and Bell Telephone Laboratories. It is considered to be the first fully automated guided missile used in combat.
A guided bomb is a precision-guided munition designed to achieve a smaller circular error probable (CEP).
The Henschel Hs 294 was a guided air-to-sea missile developed by Henschel Flugzeug-Werke in Germany during World War II.
The Kawasaki Ki-48, was a Japanese twin-engine light bomber that was used during World War II. Its Allied reporting name was "Lily".
The Mitsubishi I-Gо̄ Model 1 Kо̄, otherwise known as Ki-147 was a radio-guided air to surface missile developed by Japan in World War II. The Imperial Japanese Army's main envisioned role for the platform was for strikes against U.S. and allied ships. The Ki-147 was planned to be installed on Ki-67 heavy bombers which would act as the control platform. The Ki-147 was developed during 1944-1945 along with its sister project of the smaller Kawasaki I-Gо̄ Model 1 Otsu (Ki-148) radio-guided air-to-surface missile and the later Tokyo Imperial University designed I-Gо̄ Model 1 Hei.
Lei Ting, abbreviated as LT, is a series of precision-guided munitions (PGM) developed by Luoyang Optoelectro Technology Development Center (LOTDC), a subsidiary of Aviation Industry Corporation of China (AVIC). The first variant, LT-2, was one of the most produced laser-guided bombs in the Chinese military. The role and performance of the Lei Ting series are roughly equivalent to the Paveway.
A precision-guided munition (PGM), also called a smart weapon, smart munition, or smart bomb, is a guided munition intended to hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the Persian 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 SAM-N-2 Lark project was a solid-fuel boosted, liquid-fueled surface-to-air missile developed by the United States Navy to meet the kamikaze threat. It was developed as a crash program to introduce a medium-range defensive layer that would attack targets between the long-range combat air patrols and short-range anti-aircraft artillery. This produced a design with roughly 30 miles (48 km) maximum range and subsonic performance, suitable for attacks against Japanese aircraft.
Optical contrast seekers, or simply contrast seekers, are a type of missile guidance system using a television camera as its primary input. The camera is initially pointed at a target and then locked on, allowing the missile to fly to its target by keeping the image stable within the camera's field of view.
Television guidance (TGM) is a type of missile guidance system using a television camera in the missile or glide bomb that sends its signal back to the launch platform. There, a weapons officer or bomb aimer watches the image on a television screen and sends corrections to the missile, typically over a radio control link. Television guidance is not a seeker because it is not automated, although semi-automated systems with autopilots to smooth out the motion are known. They should not be confused with contrast seekers, which also use a television camera but are true automated seeker systems.
Funryu were a series of surface-to-air anti-aircraft missiles developed in Japan at the end of the Second World War. The missile's development in the late stages of the war was plagued by organizational problems and cancelled before becoming operational.
The GB-1, also known as the "Grapefruit bomb" and as XM-108, was a glide bomb produced by Aeronca Aircraft for the United States Army Air Forces during World War II. Intended to allow bombers to release bombs from outside the range of enemy defenses, over one thousand GB-1s were used in combat before the end of the war.
