The Qassam rocket ( 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. These rockets cannot be fired to target specific military objectives in or near civilian areas, and are "indiscriminate when used against targets in population centers".
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.
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
Name
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.
Manufacture and deployment
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. The first Qassam produced was the Qassam-1, with a maximum range of .
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. 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. 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).
Rocket, design and cost
Rocket
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. 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".
Design
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.
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.
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.
Cost
The cost of the materials used for manufacturing each Qassam is up to $800 or €500 (in 2008–2009) per rocket.
