A car bomb, bus bomb, van bomb, lorry bomb, or truck bomb, also known as a vehicle-borne improvised explosive device (VBIED),Template:Sfn is an improvised explosive device designed to be detonated in an automobile or other vehicles.

Car bombs can be roughly divided into two main categories: those used primarily to kill the occupants of the vehicle (often as an assassination) and those used as a means to kill, injure or damage people and buildings outside the vehicle. The latter type may be parked (the vehicle disguising the bomb and allowing the bomber to get away), or the vehicle might be used to deliver the bomb (often as part of a suicide bombing).

It is commonly used as a weapon of terrorism or guerrilla warfare to kill people near the blast site or to damage buildings or other property.<ref>Template:Cite news</ref> Car bombs act as their own delivery mechanisms and can carry a relatively large amount of explosives without attracting suspicion. In larger vehicles and trucks, weights of around Template:Convert or more have been used, for example, in the Oklahoma City bombing.<ref>Template:Cite web</ref> Car bombs are activated in a variety of ways, including opening the vehicle's doors, starting the engine, remote detonation, depressing the accelerator or brake pedals, or simply lighting a fuse or setting a timing device.<ref name="technology"/> The gasoline in the vehicle's fuel tank may make the explosion of the bomb more powerful by dispersing and igniting the fuel.

History

Template:Further Template:See also Car bombs have been used for attacks motivated by a wide variety of grievances and ideologies, by people and groups from a wide variety of cultural and religious backgrounds: left wing, right wing, Jewish, Catholic, Shia, Sunni, and others.<ref name="Davis The First Car Bomb"/><ref name="talks with IRA"/><ref name="Inquest Winchester"/>Template:Additional citation needed

Car bombs are preceded by the 16th century hellburners, explosive-laden ships which were used to deadly effect by the besieged Dutch forces in Antwerp against the besieging Spanish. Though using a less refined technology, the basic principle of the hellburner is similar to that of the car bomb.Template:According to whom

The first car bomb may have been the one used for the assassination attempt on Ottoman Sultan Abdul Hamid II in 1905 in Istanbul by Armenian separatists in the command of Papken Siuni belonging to the Armenian Revolutionary Federation.Template:According to whom

Car bombs were also preceded by animal bombs using horses and cows, then eventually emerging into car use.<ref name="Davis The First Car Bomb"/> Prior to the 20th century, bombs planted in horse carts had been used in assassination plots, notably the unsuccessful "machine infernale" attempt to kill Napoleon on 24 December 1800.Template:According to whom Mario Buda's improvised wagon used in the 1920 Wall Street bombing is considered a prototype of the car bomb.<ref name="Davis The First Car Bomb"/>

The first reported car bombing was the Bath School bombings in Michigan, USA in 1927. Multiple separate explosions on the same day killed 45 people, including the bomber, and half of a school was destroyed.Template:According to whom The bombings were all carried out by Andrew Kehoe, motivated by a personal grievance. His death was possibly an intentional suicide, but the cause of the explosion was a gun shot that might not have been intended to set off the load. The explosion itself did not seem to form part of a suicide attack on a specific planned target other than possibly himself and his truck. The explosives in his truck detonated when he saw two men nearby had a gun, after he set off multiple other bombs.<ref name="Inquest Page 326"/><ref name="Inquest Page 352"/> The explosion may have been set off indirectly by him firing his own gun at the men.<ref name="Inquest Winchester"/><ref name="Jones PhD Dissertation Page 1"/> Most of the deaths were caused by the earlier bombs.<ref name="ellsworth ch 2"/><ref name="Burcar"/>

Some groups in Palestine have used both cars and donkeysTemplate:Broken anchor.<ref name="972 donkey"/><ref name="MEMO 1937"/><ref name="Donkey human shield"/> The Irgun, a Zionist militant group in British controlled Palestine, abused donkeys as suicide bombers in two attacks on Haifa vegetable market in 1939.

While not an adaptation of a people-carrying vehicle, the WW2 German Goliath remote control mine shares many parallels with a vehicle-based IED. It approached a target (often a tank or another armoured vehicle) at speed before exploding, destroying itself and the target. It was armoured so that it could not be destroyed en route. However, it was not driven by a person, instead operated by remote control from a safe distance.Template:Sfn

The first non-suicide car bombing "fully conceptualized as a weapon of urban warfare" came on 12 January 1947 when the Lehi (also known as Stern Gang), a Zionist paramilitary organization, bombed the Haifa police station.<ref name="Davis The First Car Bomb"/> On 4 January 1948, a Lehi car bomb in Jaffa killed 70 Palestinian Arabs.<ref name="Haaretz Dare Compare"/>

Car bombing was a significant part of the Provisional Irish Republican Army (PIRA) campaign during The Troubles in Northern Ireland.

From a tactical point of view, it ties down a large number of security forces and troops around the main urban areas of the region in conflict.<ref name="Revolutionary in Ireland"/>

A notable suicide car bombing was the 1983 Beirut barracks bombing, when two simultaneous attacks killed 241 U.S. and 58 French peacekeepers.

As a delivery system

Car bombs are effective weapons as they are an easy way to transport a large number of explosives to a target. A car bomb also produces copious shrapnel, or flying debris, and secondary damage to bystanders and buildings. In recent years, car bombs have become widely used by suicide bombers.<ref>Template:Cite web</ref><ref>Template:Cite news</ref><ref>Template:Cite web</ref>

Countermeasures

Defending against a car bomb involves keeping vehicles at a distance from vulnerable targets by using roadblocks and checkpoints, Jersey barriers, concrete blocks or bollards, metal barriers, or by hardening buildings to withstand explosions. The entrance to Downing Street in London has been closed since 1991 in reaction to the Provisional Irish Republican Army campaign, preventing the public from approaching Number 10. Where major public roads pass near buildings, road closures may be the only option (thus, for instance, in Washington, D.C. the portion of Pennsylvania Avenue immediately in front of the White House is closed to traffic). Historically these tactics have encouraged potential bombers to target "soft" or unprotected targets, such as markets.<ref>See Davis.Template:Full citation needed</ref>

Suicide usage

In the Iraqi and Syrian Civil War, the car bomb concept was modified so that it could be driven and detonated by a driver but armoured to withstand incoming fire. The vehicle would be driven to its target area, in a similar fashion to a kamikaze plane of WW2.Template:Sfn These were known by the acronym SVBIED (from Suicide Vehicle Borne Improvised Explosive Device) or VBIEDs. Ordinary civilian cars were outfitted with armour plating intended to protect the VBIED as it approached its target.Template:Sfn Such SVBIEDs were driven into enemy troop areas or incoming enemy columns.Template:Sfn Most often, the SVBIEDs were used by ISIL against Government forces, but also used by Syrian rebels (FSA and allied militias, especially the Al-Nusra Front) against government troops.Template:Sfn

The vehicles have become more sophisticated, with armour plating on the vehicle, protected vision slits, armour plating over the wheels so they would withstand being shot at and occasionally additional metal grating over the front of the vehicle designed to crush or destroy incoming shaped charges such as those used on rocket propelled grenades.<ref>Trends Institution "Daeshis-armored-vehicle-borne IED" Template:Cite web</ref>

Trucks were sometimes used to start an assault, and benefitted from their greater storage space that could contain very heavy explosives.Template:Sfn Animal drawn carts, typically pulled by horse or mule, have also been used.Template:Sfn<ref>Template:Cite news</ref> Tactically, a single vehicle may be used, or an initial "breakthrough" vehicle, then followed by another vehicle.Template:Sfn

While many car bombs are disguised as ordinary vehicles,<ref>Template:Cite book p.166</ref> some that are used against military forces have improvised vehicle armour attached to prevent the driver from being shot when attacking a fortified outpost.<ref>Template:Cite web</ref>

Operation

Template:More citations needed

TSA officers view the post-blast remains of a Dodge Neon after an explosive was detonated inside it during training.

Car bombs and detonators function in a diverse manner of ways and there are numerous variables in the operation and placement of the bomb within the vehicle. Earlier and less advanced car bombs were often wired to the car's ignition system, but this practice is now considered more laborious and less effective than other more recent methods, as it requires a greater amount of work for a system that can often be quite easily defused. While it is more common nowadays for car bombs to be fixed magnetically to the underside of the car, underneath the passenger or driver's seat, or inside of the mudguard, detonators triggered by the opening of the vehicle door or by pressure applied to the brakes or accelerating pedals are also used.<ref name="technology"/>

Bombs operating by the former method of fixation to the underside of the car more often than not make use of a device called a tilt fuse. A small tube made of glass or plastic, the tilt fuse is similar in operation to a mercury switch or medical tablet tube. One end of the fuse will be filled with mercury, while the other open end is wired with the ends of an open circuit to an electrical firing system. When the tilt fuse moves or is jerked, the supply of mercury will flow to the top of the tube and close the circuit. Thus, as the vehicle goes through the regular bumping and dipping that comes with driving over a terrain, the circuit is completed, and the explosive is detonated.<ref name="technology"/>

Car bombs are effective as booby traps because they also leave very little evidence. When an explosion happens, it is difficult for forensics to find any evidence because things either denigrate or become charred.<ref name="Davis The First Car Bomb"/>

As a safety mechanism to protect the bomber, the placer of the bomb may rig a timing device incorporated with the circuit to activate the circuit only after a certain time period, therefore ensuring the bomber will not accidentally activate the bomb before they are able to get clear of the blast radius.<ref name="technology"/>
