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

Development and use in World War I

The first incendiary devices to be dropped during World War I fell on coastal towns in the east of England on the night of 18–19 January 1915. The small number of German bombs, also known as firebombs, were finned containers filled with

. On 8 September 1915, Zeppelin L-13 dropped a large number of firebombs, but even then the results were poor and they were generally ineffective in terms of the damage inflicted. They did have a considerable effect on the morale of the civilian population of the United Kingdom. After further experiments with 5-litre barrels of benzol, in 1918, the B-1E Elektron fire bomb (German: ''Elektronbrandbombe'') was developed by scientists and engineers at the Griesheim-Elektron chemical works. The bomb was ignited by a thermite charge, but the main incendiary effect was from the

and aluminium alloy casing, which ignited at 650 °C, burned at 1,100 °C and emitted vapour that burned at 1,800 °C. A further advantage of the alloy casing was its lightness, being a quarter of the density of steel, which meant that each bomber could carry a considerable number. The German High Command devised an operation called "The Fire Plan" (German: ''Der Feuerplan''), which involved the use of the whole German heavy bomber fleet, flying in waves over London and Paris and dropping all the incendiary bombs that they could carry, until they were either all shot down or the crews were too exhausted to fly. The hope was that the two capitals would be engulfed in an inextinguishable blaze, causing the Allies to sue for peace. Thousands of Elektron bombs were stockpiled at forward bomber bases and the operation was scheduled for August and again in early September 1918, but on both occasions, the order to take off was countermanded at the last moment, perhaps because of the fear of Allied reprisals against German cities. The

had already used their own "Baby" incendiary bomb (BIB) which also contained a thermite charge. A plan to fire bomb New York with new long range Zeppelins of the L70 class was proposed by the naval airship fleet commander Peter Strasser in July 1918, but it was vetoed by Admiral Reinhard Scheer.


Development and use in World War II

Incendiary bombs were used extensively in

as an effective bombing weapon, often in a conjunction with high-explosive bombs. Probably the most famous incendiary attacks are the bombing of Dresden and the bombing of Tokyo on 10 March 1945. Many different configurations of incendiary bombs and a wide range of filling materials such as isobutyl methacrylate (IM) polymer, napalm, and similar jellied-petroleum formulas were used, many of them developed by the US

. Different methods of delivery, e.g. small bombs, bomblet clusters and large bombs, were tested and implemented. For example, a large bomb casing was filled with small sticks of incendiary ( bomblets); the casing was designed to open at altitude, scattering the bomblets in order to cover a wide area. An explosive charge would then ignite the incendiary material, often starting a raging fire. The fire would burn at extreme temperatures that could destroy most buildings made of wood or other combustible materials (buildings constructed of stone tend to resist incendiary destruction unless they are first blown open by high explosives). The German ''

'' started the war using the 1918-designed one-kilogram magnesium alloy B-1E ''Elektronbrandbombe''; later modifications included the addition of a small explosive charge intended to penetrate the roof of any building which it landed on. Racks holding 36 of these bombs were developed, four of which could, in turn, be fitted to an electrically triggered dispenser so that a single He 111 bomber could carry 1,152 incendiary bombs, or more usually a mixed load. Less successful was the ''Flammenbombe'', a 250 kg or 500 kg high explosive bomb case filled with an inflammable oil mixture, which often failed to detonate and was withdrawn in January 1941. In World War II, incendiaries were principally developed in order to destroy the many small, decentralised war industries located (often intentionally) throughout vast tracts of city land in an effort to escape destruction by conventionally aimed high-explosive bombs. Nevertheless, the civilian destruction caused by such weapons quickly earned them a reputation as terror weapons with the targeted populations.

with a cast iron/steel nose, and filled with thermite incendiary pellets. It was capable of burning for up to ten minutes. There was also a high explosive version and delayed high explosive versions (2–4 minutes) which were designed to kill rescuers and firefighters. It was normal for a proportion of high explosive bombs to be dropped during incendiary attacks in order to expose combustible material and to fill the streets with craters and rubble, hindering rescue services. Towards the end of World War Two, the British introduced a much improved incendiary bomb, whose fall was retarded by a small parachute and on impact sent out an extremely hot flame for ; This, the "Incendiary Bomb, 30-lb., Type J, Mk I", burned for approximately two minutes. Articles in late 1944 claimed that the flame was so hot it could crumble a brick wall. For propaganda purposes the RAF dubbed the new incendiary bomb the "Superflamer".

Incendiary weapons after World War II

Napalm was widely used by the United States during the
Korean War The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was s ...

Napalm however, became an intrinsic element of US military action during the Vietnam War as forces made increasing use of it for its tactical and psychological effects.

Signatory states are bound by Protocol III of the UN Convention on Conventional Weapons which governs the use of incendiary weapons: * prohibits the use of incendiary weapons against civilians (effectively a reaffirmation of the general prohibition on attacks against civilians in Additional Protocol I to the
Geneva Conventions upright=1.15, The original document in single pages, 1864 The Geneva Conventions are international humanitarian laws consisting of four treaties and three additional protocols that establish international legal standards for humanitarian t ...
) * prohibits the use of air-delivered incendiary weapons against military targets located within concentrations of civilians and loosely regulates the use of other types of incendiary weapons in such circumstances.although the 4th Geneva Convention, Part 3, Article 1, Section 28 states ''"The presence of a protected person(s) may not be used to render certain points or areas immune from military operations."'' Protocol III states though that incendiary weapons do not include: * Munitions which may have incidental incendiary effects, such as illuminates, tracers, smoke or signaling systems; * Munitions designed to combine penetration, blast or fragmentation effects with an additional incendiary effect, such as armor-piercing projectiles, fragmentation shells, explosive bombs and similar combined-effects munitions in which the incendiary effect is not specifically designed to cause burn injury to persons, but to be used against military objectives, such as armoured vehicles, aircraft and installations or facilities.
