Qassam rocket
View on WikipediaThis article needs to be updated. (October 2025) |
The Qassam rocket (Arabic: صاروخ القسام Ṣārūkh al-Qassām; also Kassam) is a simple, steel artillery rocket developed and deployed by the Izz ad-Din al-Qassam Brigades, the military arm of Hamas.
Key Information
Since the rocket was first manufactured in 2001 by Tito Masoud and Nidal Farhat, three models of the Qassam rocket have been produced and used. More generally, all types of Palestinian rockets fired into southern Israel, for example the Palestinian Islamic Jihad Al Quds rockets, are called Qassams by the Israeli media, and often by foreign media.[3]
Leading international human rights organizations have called Palestinian armed groups' use of Qassam rockets against civilian and civilian targets a war crime and a violation of international law.
Many of the rocket's components are made of common materials such as sugar, fertilizer, firearms cartridges, springs, nails, and steel cylinders.
History
[edit]Name
[edit]Qassam rockets are named after the Izz ad-Din al-Qassam Brigades, the armed branch of Hamas, itself named for Izz ad-Din al-Qassam, a Syrian Muslim preacher whose death during a guerrilla raid against British Mandatory authorities in 1935 was one of the catalysts for the 1936–39 Arab revolt in Palestine.[citation needed]
Manufacture and deployment
[edit]Tito Masoud and Nidal Farhat manufactured the first Qassam-1 rocket, with a 2,500m range, in June 2001. This development in rocket manufacturing and development was a turning point in the war between Palestinian armed factions and Israel.[4] The first Qassam produced was the Qassam-1, with a maximum range of 3 to 4.5 kilometers (1.9 to 2.8 mi).[citation needed]
Hamas launched the first Qassam-1 rocket attack in October 2001, during the Second Intifada. The first time Palestinians launched rockets into Israel, rather than at an Israeli settlement in the Gaza Strip, occurred on February 10, 2002. One of the rockets landed in Kibbutz Saad.[5] Two Qassam rockets landed in the southern Israeli city of Sderot, the first city hit, on March 5, 2002. Some rockets have hit as far as the edge of Ashkelon. By the end of December 2008, a total of 15 people had been killed by Palestinian rockets since attacks began in 2001.[6] Since 2000, Palestinian rockets, which include the Qassam, alongside others such as the Grad rocket, have been used to kill 22 Israeli citizens and one Thai national (as of January 9, 2009).[7][8]
Description
[edit]
The Qassam rocket is the best-known type of rocket deployed by Palestinian militants, mainly against Israeli civilians, but also some military targets during the Second Intifada of the Israeli–Palestinian conflict.[9][10] According to Human Rights Watch, Qassam rockets are too inaccurate and prone to malfunction to be used against specific military targets in or near civilian areas, and are mainly launched for the purpose of "harming civilians".[10]
The utility of the Qassam rocket design is assumed to be ease and speed of manufacture, using common tools and components. To this end, the rockets are propelled by a solid mixture of sugar and potassium nitrate, a common fertilizer. The warhead is filled with smuggled or scavenged TNT and urea nitrate, another common fertilizer. The warhead's explosive material is similar to the civilian explosive ammonite.[11]
The rocket consists of a steel cylinder, containing a rectangular block of the propellant. A steel plate which forms and supports the nozzles is then spot-welded to the base of the cylinder. The warhead consists of a simple metal shell surrounding the explosives, and is triggered by a fuse constructed using a simple firearm cartridge, spring and a nail.[11]
Early designs used a single nozzle which screwed into the base; later rockets use a seven-nozzle design, with the nozzles drilled directly into the rocket baseplate. This alteration both increases the tolerance of the rocket to small nozzle design defects, and makes manufacture easier by allowing the use of a drill rather than a lathe during manufacture (because of the smaller nozzle size). Unlike many other rockets, the nozzles are not canted, which means the rocket does not spin about its longitudinal axis during flight. While this results in a significant decrease in accuracy, it greatly simplifies manufacture and the launch systems required.[11]
The cost of the materials used for manufacturing each Qassam was up to $800 or €500 per rocket in 2009.[12][13]
Reactions
[edit]Israeli
[edit]
The introduction of the Qassam rocket was unexpected by Israeli politicians and military experts,[14] and reactions have been mixed.[15] In 2006, the Israeli Ministry of Defense viewed the Qassams as "more a psychological than physical threat."[16] A 2008 study found that over half of Sderot's residents have been hurt, either physically or psychologically, by the use of Qassams.[17] The Israel Defense Forces has reacted to the deployment of the Qassam rockets by deploying the Red Color early warning system in Sderot, Ashkelon, and other potential targets placed at risk. The system consists of an advanced radar that detects rockets as they are being launched, and loudspeakers warn civilians to take cover between 15 and 45 seconds before impact[18] in an attempt to minimize the threat posed by the rockets. A system called Iron Dome, designed to intercept[19] the rockets before they can hit their targets, has been in use since March 2011. A system based on lasers (Nautilus) was researched in a joint Israeli-American project in the early 2000s, but was discontinued.[citation needed]
An online clock timer,[20] developed by Aaron Friedman and Yehonatan Tsirolnik, that automatically resets when Palestinian rocket attacks on Israel occur uses information from the IDF Home Front Command system and counts time up from the last Palestinian rocket attack on Israel. It displays how long Israel has been rocket-free and shows the summed-up total numbers of Palestinian rocket attacks on Israel.[20][21] "Israel has been under non-stop rocket attacks for years (..) Whenever a rocket is fired, it restarts. Sadly, this counter never really gets above an hour", Friedman said on July 18, 2014, during the 2014 Israel–Gaza conflict.[22][23] An amateur YouTube video, showing the Israeli Iron Dome defense system at a military checkpoint near a crossing into Gaza taking out multiple Qassam rockets was uploaded in 2014.[19][24]
Palestinian
[edit]In 2012, Palestinian president Mahmoud Abbas stated "There is no justification for rockets from Gaza or anywhere else," adding that "Rocket attacks are in vain because they do not bring peace any closer."[25]
Ibrahim Khreisheh, the Palestinian envoy to the United Nations Human Rights Council (UNHRC), stated in an PA TV interview on July 9, 2014 (translated by MEMRI) that indiscriminate Hamas rockets from densely populated residential areas are "crimes against humanity", while Israeli strikes are legal responses.[26][27]
Human rights groups
[edit]Amnesty International labeled Palestinian groups' use of rockets during the 2014 Gaza war as a "war crime", stating that "Palestinian armed groups operating in the Gaza Strip fired thousands of indiscriminate rockets and mortars into Israel; firing munitions which cannot be aimed accurately into civilian areas is a war crime, and statements by Hamas and Palestinian armed groups also indicates that some attacks were intended to kill or injure civilians."[28]
Amnesty additionally "has documented that Palestinian armed groups have stored munitions in and fired indiscriminate rockets from residential areas in the Gaza Strip, and available evidence indicates that they continue to do both during the current hostilities, in violation of international humanitarian law (..) Under international humanitarian law, (..) Parties to the conflict must also take necessary precautions to protect civilians in their power from the effects of attack. This includes avoiding, to the maximum extent feasible, co-locating military objectives in the vicinity of densely populated civilian neighbourhoods. This means the parties should avoid endangering civilians by storing ammunition in, and launching attacks from, populated civilian areas."[29]
Human Rights Watch has called the use of Qassam rockets by Hamas against civilians and civilian targets illegal under international law. In a 2005 statement, the group said that "such weapons are therefore indiscriminate when used against targets in population centers. The absence of Israeli military forces in the areas where rockets have hit, as well as statements by leaders of Palestinian armed groups that population centers were being targeted, indicate that the armed groups deliberately attacked Israeli civilians and civilian objects."[30] In another 2005 statement, the group noted that as the ruling authority of Gaza, Hamas was obligated to uphold the laws of war and should appropriately punish those responsible for serious violations".[10] The international community considers indiscriminate attacks on civilians and civilian structures that do not discriminate between civilians and military targets as illegal under international law.[29][30]

Qassam rocket
View on GrokipediaOrigins and Development
Invention and Naming
The Qassam rocket was developed by the Izz ad-Din al-Qassam Brigades, the military wing of Hamas, as an improvised, unguided steel artillery rocket intended for short-range attacks from the Gaza Strip.[2] [3] The initial variant, designated Qassam-1, emerged in makeshift workshops using scavenged materials like steel pipes and homemade propellant, with the first launches occurring in October 2001 amid the Second Intifada.[2] [3] This crude design allowed production in garages and small laboratories, circumventing import restrictions on conventional arms, though early models suffered from limited range (3-4.5 kilometers) and inaccuracy due to the absence of guidance systems.[2] The name "Qassam" honors Izz ad-Din al-Qassam, a Syrian Muslim Brotherhood preacher who led guerrilla operations against British colonial forces and Jewish settlements in Mandatory Palestine until his death in a 1935 ambush.[2] The Brigades, formed in the late 1980s as Hamas's armed faction, adopted his surname to evoke his legacy of Islamist insurgency, framing the rocket as a continuation of asymmetric warfare against Israeli targets.[6] This nomenclature underscores the weapon's ideological roots in jihadist narratives of resistance, distinct from technical designations of imported munitions.[2]Early Testing and Variants
The Qassam-1, the initial variant of the rocket, was developed by Hamas's Izz ad-Din al-Qassam Brigades in the Gaza Strip using rudimentary materials and improvised designs modeled partly on commercial fireworks and historical artillery concepts. Early testing involved prototype launches in the late 1990s, but the first documented operational test firing targeted the Israeli town of Sderot on October 26, 2001, during the Second Intifada, achieving a range of approximately 3 kilometers with a 0.5-kilogram warhead filled with explosives. This launch demonstrated basic functionality despite inaccuracies and low reliability, serving as a proof-of-concept for unguided, solid-fuel rocketry produced without advanced machinery.[7][2] Subsequent variants emerged through iterative improvements based on field testing via combat launches, focusing on extending range and payload capacity. The Qassam-2, introduced around 2002, featured a longer body and enhanced propellant, yielding a range of 8-10 kilometers and a warhead of up to 3 kilograms, with launches increasing in frequency to refine stability and trajectory. By 2004, the Qassam-3 variant further optimized aerodynamics and fuel composition, attaining ranges of 10-12 kilometers or more and warheads weighing 5-10 kilograms, as evidenced by attacks reaching deeper into southern Israel. These evolutions relied on empirical adjustments from launch data rather than formal engineering, with production scaling in makeshift workshops amid resource constraints.[7][8] Early testing highlighted inherent limitations, including high failure rates—estimated at 50% or more in initial batches due to inconsistent propellant mixing—and minimal guidance, rendering most impacts random within a broad error cone. Variants like the Qassam-4, tested by mid-2000s, incorporated minor stabilizers for slight accuracy gains but retained the core steel-tube construction and black powder-based fuel, prioritizing quantity over precision in asymmetric warfare contexts. Israeli intelligence assessments noted that these developments accelerated post-2001, correlating with over 200 launches by 2003, which provided real-world data for refinements despite interception challenges from nascent defenses like the Iron Dome precursors.[2]Manufacturing Processes
Qassam rockets are produced in decentralized workshops throughout the Gaza Strip, often utilizing basic civilian infrastructure and improvised techniques to evade detection. Manufacturing relies on readily available materials sourced from local industries, smuggling tunnels, or diversion from agricultural and construction supplies, enabling Hamas's Izz ad-Din al-Qassam Brigades to maintain output despite blockades.[2][9] The process emphasizes simplicity, with production equipment limited to lathes, welding tools, and mixing vats that do not require specialized industrial facilities.[2] The core body of the rocket consists of steel or iron pipes, typically 2-4 inches in diameter and 1-3 meters in length depending on the variant, sourced from plumbing or industrial scrap. These tubes are cut, welded, and reinforced to form the casing, which houses the propellant and warhead sections. Stabilizing fins, constructed from sheet metal or rods, are attached to the rear via welding or bolting for rudimentary guidance. Warheads, weighing 5-10 kg, are fabricated by packing the nose cone with improvised explosives such as urea-formaldehyde mixtures or scavenged TNT, often combined with shrapnel like nails or ball bearings to enhance fragmentation effects.[2][3][4] Propellant, the critical propulsion element, is a solid-fuel composite prepared by melting and mixing sugar (as the fuel binder) with potassium nitrate (an oxidizer derived from fertilizer) in approximate ratios of 60:40 by weight, then casting the viscous slurry into solid grains or slugs within the pipe body. This "rocket candy" formulation, ignited by a simple electrical fuse connected to batteries, provides thrust for ranges of 3-16 km across Qassam variants, though inconsistencies in mixing lead to variable burn rates and frequent failures. Some raw chemicals, including refined potassium nitrate, are smuggled or stolen from external suppliers to supplement local production, allowing scalability to hundreds of units monthly during escalations.[2][9][3] Assembly concludes with sealing the warhead and integrating a basic nozzle from machined metal, followed by testing in isolated areas; the entire process for a single rocket can be completed by small teams in hours using non-specialized labor.[10][11]Technical Design
Construction and Materials
The fuselage of the Qassam rocket is fabricated from standard steel pipes, typically sourced from local markets or repurposed from civilian infrastructure such as sewage systems, providing a simple and accessible structural core.[2][12] These pipes are cut and welded to form the rocket body, with stabilizing fins attached using basic metalworking techniques, enabling production in makeshift workshops without specialized industrial equipment.[2] The propellant system employs a rudimentary solid fuel composed of sugar mixed with potassium nitrate, an agricultural fertilizer serving as the oxidizer, which is cast into the rocket's motor section after melting and combining the ingredients.[5][2] This low-grade mixture, akin to amateur rocketry formulations, yields inconsistent burn rates and thrust, contributing to the weapon's limited range and accuracy.[5] Warheads are packed with improvised explosives, including smuggled trinitrotoluene (TNT) or homemade urea nitrate derived from fertilizer, often supplemented with scrap metal for shrapnel effects upon detonation.[3] The assembly process relies on scavenged or commercially available components, underscoring the design's emphasis on low-cost, clandestine manufacturing adaptable to resource constraints in Gaza.[2]Specifications and Performance
The Qassam rocket is an improvised, unguided solid-fuel artillery rocket, constructed primarily from readily available materials such as steel pipes for the body, homemade propellant consisting of potassium nitrate and sugar, and warheads filled with urea nitrate explosive mixed with TNT and augmented by metal shrapnel.[13] Its design prioritizes simplicity and low cost over precision, enabling production in small workshops with minimal industrial infrastructure.[4] Specifications vary across variants, which evolved to extend range and payload capacity. The Qassam-1, the earliest model introduced around 2001, has a length of approximately 1.8 meters, diameter of 115 mm, total weight of about 35 kg, maximum range of 3 km, and warhead of roughly 8 kg.[4] Subsequent iterations improved performance: the Qassam-2 maintains similar dimensions but achieves up to 7 km range with a lighter warhead of around 4 kg; the Qassam-3 extends length to 2.4 meters and range to 10 km with an 8 kg warhead; while the Qassam-4 reaches 14.5 km with a 10 kg warhead.[4] Later developments, such as the Qassam-3 reported in 2005, incorporated warheads up to 20 kg, though actual payloads often range from 5-9 kg in second-generation models.[13]| Variant | Length (m) | Diameter (mm) | Weight (kg) | Max Range (km) | Warhead (kg) |
|---|---|---|---|---|---|
| Qassam-1 | 1.8 | 115 | 35 | 3 | 8 |
| Qassam-2 | 1.8 | 115 | 40 | 7 | 4 |
| Qassam-3 | 2.4 | 115 | 50 | 10 | 8 |
| Qassam-4 | 2.6 | 115 | 50 | 14.5 | 10 |
