Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical (usually gasoline or diesel fuel). The name is a portmanteau of two of the constituents of the original thickening and gelling agents: coprecipitated aluminium salts of naphthenic acid and palmitic acid. [1] A team led by chemist Louis Fieser originally developed napalm for the US Chemical Warfare Service in 1942 in a secret laboratory at Harvard University. [2] Of immediate first interest was its viability as an incendiary device to be used in fire bombing campaigns during World War II; its potential to be coherently projected into a solid stream that would carry for distance (instead of the bloomy fireball of pure gasoline) resulted in widespread adoption in infantry and tank/boat mounted flamethrowers as well.

Napalm burns at temperatures ranging from 800 to 1,200 °C (1,470 to 2,190 °F). [3] [4] It burns longer than gasoline, is more easily dispersed, and adheres to its targets. These traits make it both effective and controversial. It has been widely used from the air and from the ground, the largest use having been via airdropped bombs in World War II in the incendiary attacks on Japanese cities in 1945. It was used also for close air support roles in the Korean War, the Vietnam War, and various others. Napalm has also fueled most of the flamethrowers (tank-, ship-, and infantry-based) used since World War II, giving them much greater range.

Development

The development of napalm was precipitated by the use of jellied gasoline mixtures by the Allied forces during World War II. [5] Latex, used in these early forms of incendiary devices, became scarce, since natural rubber was almost impossible to obtain after the Japanese army captured the rubber plantations in Malaya, Indonesia, Vietnam, and Thailand.

This shortage of natural rubber prompted chemists at US companies such as DuPont and Standard Oil of New Jersey, and researchers at Harvard University, to develop factory-made alternatives: artificial rubber for all uses, including vehicle tires, tank tracks, gaskets, hoses, medical supplies and rain clothing. A team of chemists led by Louis Fieser at Harvard University was the first to develop synthetic napalm during 1942. [6] "The production of napalm was first entrusted to Nuodex Products, and by the middle of April 1942 they had developed a brown, dry powder that was not sticky by itself, but when mixed with gasoline turned into an extremely sticky and flammable substance." One of Fieser's colleagues suggested adding phosphorus to the mix which increased the "ability to penetrate deeply [...] into the musculature, where it would continue to burn day after day." [7]

On 4 July 1942, the first test occurred on the football field near the Harvard Business School. [7] Tests under operational conditions were carried out at Jefferson Proving Ground on condemned farm buildings and subsequently at Dugway Proving Ground on buildings designed and constructed to represent those to be found in German and Japanese towns. [8] This new mixture of chemicals was first approved for use on the front lines in 1943. [9]

Military use

World War II

The first use of napalm in combat was in August 1943 during the Allied invasion of Sicily, when American troops, using napalm-fueled flamethrowers, burned down a wheat field where German forces were believed to be hiding. [10] Napalm incendiary bombs were first used the following year, although the exact date and battle are disputed. [a]

Two-thirds of napalm bombs produced during WWII were used in the Pacific War. Napalm was often deployed against Japanese fortifications on Saipan, Iwo Jima, the Philippines, and Okinawa, where deeply dug-in Japanese troops refused to surrender. [11] Following a shortage of conventional thermite bombs, General Curtis LeMay, among other high-ranking servicemen, ordered air raids on Japan to start using napalm instead. [14] A 1946 report by the National Defense Research Council claims that 40,000 tons of M69s were dropped on Japan throughout the war, [15] [16] damaging 64 cities and causing more deaths than the atomic bombings of Hiroshima and Nagasaki. [17]

German fortifications and transportation hubs were targeted with napalm during both Operation Overlord and the Battle of the Bulge, sometimes in conjunction with artillery. [11] During the Allied siege of La Rochelle, napalm was dropped on the outskirts of the Royan pocket, inadvertently killing French civilians. [18]

The Royal Air Force (RAF) used napalm to a limited extent in both the Pacific War and the European Theater. [19] [20]

Korean War

Napalm was widely used by the US during the Korean War. [10] [21] [22] The ground forces in North Korea holding defensive positions were often outnumbered by Chinese and North Koreans, but US Air Force and Navy aviators had control of the air over nearly all of the Korean Peninsula. Hence, the American and other UN aviators used napalm for close air support of the ground troops. [21] Napalm was used most notably at the beginning of the Battle of Outpost Harry. [23] [24]

Eighth Army chemical officer Donald Bode reported that, on an "average good day", UN pilots used 260,000 liters (70,000 US gal; 58,000 imp gal) of napalm, with approximately 230,000 liters (60,000 US gal; 50,000 imp gal) of this thrown by US forces. [10] The New York Herald Tribune hailed "Napalm, the No. 1 Weapon in Korea". [22] British Prime Minister Winston Churchill privately criticized the use of napalm in Korea, writing that it was "very cruel", as US/UN forces, he wrote, were "splashing it all over the civilian population", "tortur[ing] great masses of people". He conveyed these sentiments to U.S. Chairman of the Joint Chiefs of Staff Omar Bradley, who "never published the statement". Publicly, Churchill allowed Bradley "to issue a statement that confirmed U.K. support for U.S. napalm attacks". [10]

Vietnam War

Napalm 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. [9] [25] Reportedly about 352,000 tonnes (388,000 short tons; 346,000 long tons) of US napalm bombs were dropped in the region between 1963 and 1973. [10] The US Air Force and US Navy used napalm with great effect against all kinds of targets, such as troops, tanks, buildings, jungles, and even railroad tunnels. The effect was not always purely physical as napalm had psychological effects on the enemy as well. [26]

Others

During the Greek Civil War, after the capture of Mount Vitsi during Operation Pyrsos, the Hellenic Air Force bombed Mount Grammos—a stronghold for the opposing Democratic Army of Greece—with US-supplied napalm. [27] [28]

The French Air Force regularly used napalm for close air support of ground operations in both the First Indochina War [29] [30] and the Algerian War. [31] [32] At first, the canisters were simply pushed out the cargo doors of transport planes, such as the Amiot AAC.1; [33] later mostly B-26 bombers were used.[ citation needed ]

Peruvian forces employed napalm throughout the 1960s against both communist insurgents and the Matsés indigenous group; four prominent Matsés villages were bombed during the 1964 Matsés massacres  [ es ]. [34]

From 1968–1978, Rhodesia produced a variant of napalm for use in the Rhodesian Bush War, [35] nicknamed Frantan (short for "frangible tank"). [36] Around the same time, its ally South Africa targeted guerrilla bases in Angola with napalm during the South African Border War. [37] [38]

In 2018, Turkey was accused of using napalm in Operation Olive Branch against Kurdish nationalist groups. [39]

Antipersonnel effects

When used as a part of an incendiary weapon, napalm causes severe burns. During combustion, napalm deoxygenates the available air and generates carbon monoxide and carbon dioxide, so asphyxiation, unconsciousness, and death are also possible. [40]

Napalm is lethal even for dug-in enemy personnel, as it flows into foxholes, tunnels, and bunkers, and drainage and irrigation ditches and other improvised troop shelters. Even people in undamaged shelters can be killed by hyperthermia, radiant heat, dehydration, asphyxiation, smoke exposure, or carbon monoxide poisoning. [40] Crews of armored fighting vehicles are also vulnerable, due to the intense heat conducted through the armor. Even in the case of a near miss, the heat can be enough to disable a vehicle. [41]

One firebomb released from a low-flying plane can damage an area of 2,100 square meters (2,500 sq yd). [40]

International law

International law does not specifically prohibit the use of napalm or other incendiaries against military targets, but use against civilian populations was banned under Protocol III of the United Nations Convention on Certain Conventional Weapons in 1980, which entered into force as international law in December 1983. [9] [42] [43] As of January 2023, 126 countries have ratified Protocol III. [44]

The killing of civilians and non-combatants in bombed cities has variously been a deliberate goal of strategic bombing, or unavoidable collateral damage resulting from intent and technology. A number of multilateral efforts have been made to restrict the use of aerial bombardment so as to protect non-combatants and other civilians.

<span class="mw-page-title-main">Incendiary device</span> Weapons intended to start fires

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.

Fritz Johann Hansgirg (1891–1949) was an Austrian electrochemist and metallurgist who in 1928 invented a carbothermic magnesium reduction process. In 1934, he left Austria for the Empire of Japan where he worked with industrialist Shitagau Noguchi to set up a magnesium plant, and then helped build a pilot plant to produce heavy water using a combined electrolysis catalytic exchange process he had invented. He moved to the United States in 1940, where he worked with industrialist Henry J. Kaiser to design a magnesium plant in California. In 1941, Hansgirg was arrested by the FBI on a presidential warrant and interned for "the duration of the war". After the war, the Soviet Union captured Hansgirg's plants in northern Korea, using the plants' processes and equipment for their atomic bomb project.
