A cluster munition is a form of air-dropped or ground-launched explosive weapon that releases or ejects smaller submunitions. Commonly, this is a cluster bomb that ejects explosive bomblets that are designed to kill personnel and destroy vehicles. Other cluster munitions are designed to destroy runways or electric power transmission lines.
The GATOR mine system is a United States military system of air-dropped anti-tank and anti-personnel mines developed in the 1980s to be compatible with existing cluster dispensers. It is used with two dispenser systems—the Navy 230 kg (500 lb) CBU-78/B and the Air Force 450 kg (1,000 lb) CBU-89/B. Additionally the mines are used with the land- and helicopter-based Volcano mine system.
Incendiary weapons, incendiary devices, incendiary munitions, or incendiary bombs are weapons designed to start fires. They may destroy structures or sensitive equipment using fire, and sometimes operate as anti-personnel weaponry. Incendiaries utilize materials such as napalm, thermite, magnesium powder, chlorine trifluoride, or white phosphorus. Though colloquially often called "bombs", they are not explosives but in fact operate to slow the process of chemical reactions and use ignition rather than detonation to start or maintain the reaction. Napalm, for example, is petroleum especially thickened with certain chemicals into a gel to slow, but not stop, combustion, releasing energy over a longer time than an explosive device. In the case of napalm, the gel adheres to surfaces and resists suppression.
Unexploded ordnance, unexploded bombs (UXBs), and explosive remnants of war are explosive weapons that did not explode when they were employed and still pose a risk of detonation, sometimes many decades after they were used or discarded. When unwanted munitions are found, they are sometimes destroyed in controlled explosions, but accidental detonation of even very old explosives also occurs, sometimes with fatal results. A dud is an unexploded projectile fired in anger against an enemy, but which has failed to explode. A projectile not fired in anger but which has failed to explode is called a 'blind'.
The AGM-154 Joint Standoff Weapon (JSOW) is a glide bomb that resulted from a joint venture between the United States Navy and Air Force to deploy a standardized medium range precision guided weapon, especially for engagement of defended targets from outside the range of standard anti-aircraft defenses, thereby increasing aircraft survivability and minimizing friendly losses. It is intended to be used against soft targets such as parked aircraft, trucks, armored personnel carriers (APCs), and surface-to-air missile sites (SAMs). Prior to launch, it is given a destination through either a predesignated waypoint or a point marked through a targeting pod. It glides, using two wings that pop out for added lift, to the marked destination and dispenses submunitions in a short, roughly linear pattern. The designation of the Joint Standoff Weapon as an "air-to-ground missile" is a misnomer, as it is an unpowered bomb with guidance avionics, similar to the older GBU-15.
The Butterfly Bomb was a German 2-kilogram (4.4 lb) anti-personnel submunition used by the Luftwaffe during the Second World War. It was so named because the thin cylindrical metal outer shell which hinged open when the bomblet deployed gave it the superficial appearance of a large butterfly. The design was very distinctive and easy to recognise. SD 2 bomblets were not dropped individually, but were packed into containers holding between 6 and 108 submunitions e.g. the AB 23 SD 2 and AB 250-3 submunition dispensers. The SD 2 submunitions were released after the container was released from the aircraft and had burst open. Because SD 2s were always dropped in groups the discovery of one unexploded SD 2 was a reliable indication that others had been dropped nearby. This bomb type was one of the first cluster bombs ever used in combat and it proved to be a highly effective weapon. The bomb containers that carried the SD 2 bomblets and released them in the air were nicknamed the "Devil's Eggs" by Luftwaffe air and ground crew.
Anti-runway penetration bombs are explosive weapons involving bombs or bomblets designed to damage or destroy runways, or otherwise render them unusable for aircraft.
The CBU-97 Sensor Fuzed Weapon is a United States Air Force 1,000-pound (450 kg)-class freefall Cluster Bomb Unit. It was developed and produced by Textron Defense Systems. A CBU-97 used in conjunction with the Wind Corrected Munitions Dispenser guidance tail kit is converted to a precision-guided weapon, and the combination is designated CBU-105.
The Mk 20 Rockeye II, CBU-99 Rockeye II, and CBU-100 Rockeye II comprise an American cluster bomb family which are employed primarily in an anti-tank mode against armored vehicles.
The CBU-24 is an unguided, aircraft delivered anti-personnel and anti-materiel weapon developed by the United States. Because it is an unguided weapon, the CBU-24 can be carried and dropped by any aircraft capable of carrying standard "dumb" or "iron" bombs.
A dual-purpose improved conventional munition (DPICM) is an artillery or surface-to-surface missile warhead designed to burst into submunitions at an optimum altitude and distance from the desired target for dense area coverage. The submunitions use both shaped charges for the anti-armor role, and fragmentation for the antipersonnel role, hence the nomenclature "dual-purpose". Some submunitions may be designed for delayed reaction or mobility denial (mines). The air-to-surface variety of this kind of munition is better known as a cluster bomb. They are banned by more than 100 countries under the Convention on Cluster Munitions.
The AGM-124 Wasp is a missile developed by the United States. The Wasp grew out of the 1975 WAAM program initiated by the US Air Force in order to develop a series of new air-to-ground anti-armour weapons for close-support aircraft. The three-pronged program led to the CBU-92/B ERAM, the CBU-90/B ACM, and the Wasp anti-armour missile. The Wasp is regarded as the most advanced of these weapons.
BLU-43/B and BLU-44/B "Dragontooth" were air-dropped cluster-type land mines used by the United States during the Vietnam War. It is chemically activated and has a relatively low explosive content, typically maiming rather than killing.
The CBU-87 Combined Effects Munition (CEM) is a cluster bomb used by the United States Air Force, developed by Aerojet General/Honeywell and introduced in 1986 to replace the earlier cluster bombs used in the Vietnam War. CBU stands for Cluster Bomb Unit. When the CBU-87 is used in conjunction with the Wind Corrected Munitions Dispenser guidance tail kit, it becomes much more accurate, and is designated CBU-103.
The BLU-108 is an air-delivered submunition, containing four further smart "Skeet" warheads. The system is manufactured by Textron Systems Weapon & Sensor Systems since 1992. The BLU-108 is released from a munitions dispenser, with a parachute being used to slow its descent. It then fires the four rapidly rotating skeets, which use multi-mode optical sensors to identify a variety of targets ranging from tanks and missile launchers to railway locomotives and stationary aircraft. When the skeet passes over what it considers a high priority target, it fires a 0.9 kg explosively formed penetrator providing armor-piercing and incendiary effects, as well as a fragmentation ring meant to damage any soft targets, primarily enemy personnel, in the immediate vicinity of the target.
The CBU-55 was a cluster bomb fuel–air explosive that was developed during the Vietnam War by the United States Air Force, and was used only infrequently in that conflict. Unlike most incendiaries, which contained napalm or phosphorus, the 750-pound (340 kg) CBU-55 was fueled primarily by propane. Described as "the most powerful non-nuclear weapon in the U.S. arsenal," the device was one of the more powerful conventional weapons designed for warfare.
The CBU-72 was a 550-pound (250 kg) American fuel-air cluster bomb used by the United States Military until 1996. It was very effective against armored vehicles, aircraft parked in the open, bunkers, and minefields.
The Convention on Cluster Munitions (CCM) is an international treaty that prohibits all use, transfer, production, and stockpiling of cluster munitions, a type of explosive weapon which scatters submunitions ("bomblets") over an area. Additionally, the convention establishes a framework to support victim assistance, clearance of contaminated sites, risk reduction education, and stockpile destruction. The convention was adopted on 30 May 2008 in Dublin, and was opened for signature on 3 December 2008 in Oslo. It entered into force on 1 August 2010, six months after it was ratified by 30 states. As of December 2023, a total of 124 states are committed to the goal of the convention, with 112 states that have ratified it, and 12 states that have signed the convention but not yet ratified it.a
The E14 munition was a cardboard sub-munition developed by the United States biological weapons program as an anti-crop weapon. In a series of field tests in 1955, the E14 was loaded with fleas and air-dropped.
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.
