Scud missile

A Scud missile is one of a series of tactical ballistic missiles developed by the Soviet Union during the Cold War. It was exported widely to both Second and Third World countries. The term comes from the NATO reporting name attached to the missile by Western intelligence agencies. The Russian names for the missile are the R-11, and the R-17 Elbrus. The name Scud has been widely used to refer to these missiles and the wide variety of derivative variants developed in other countries based on the Soviet design.

(2007) The first use of the term Scud was in the NATO name SS-1b Scud-A, applied to the R-11 Zemlya ballistic missile. The earlier R-1 missile had carried the NATO name SS-1 Scunner, but was of a very different design, almost directly a copy of the German V-2 rocket. The R-11 used technology gained from the V-2 as well, but was a new design, smaller and differently shaped than the V-2 and R-1 weapons. The R-11 was developed by the Korolyev OKB and entered service in 1957. The most revolutionary innovation in the R-11 was the engine, designed by A. M. Isaev. Far simpler than the V-2's multi-chamber design, and employing an anti-oscillation baffle to prevent chugging, it was a forerunner to the larger engines used in Soviet launch vehicles. Further developed variants were the R-17 (later R-300) Elbrus / SS-1c Scud-B in 1961 and the SS-1d Scud-C in 1965, both of which could carry either a conventional high-explosive, a 5- to 80-kiloton thermonuclear, or a chemical (thickened VX) warhead. The SS-1e Scud-D variant developed in the 1980s can deliver a terminally guided warhead capable of greater precision. All models are long (except Scud-A, which is shorter) and in diameter. They are propelled by a single liquid-fuel rocket engine burning kerosene and corrosion-inhibited red fuming nitric acid (IRFNA) with a mixture of 50% triethylamine and 50% xylidine (Russian TG-02 like German Tonka 250) as liquid igniter (self-ignition with IRFNA) in all models. The missile reaches a maximum speed of Mach 5. ==Variants==
Variants
Scud-A The first of the "Scud" series, designated R-11 (SS-1B Scud-A) originated in a 1951 requirement for a ballistic missile with similar performance to the German V-2 rocket. The R-11 was developed by engineer Viktor Makeev, who was then working in the OKB-1, headed by Sergey Korolev. It first flew on 18 April 1953, was fitted with an Isayev engine using kerosene and nitric acid as propellant. On 13 December 1953, a production order was passed with SKB-385 in Zlatoust, a factory dedicated to producing long-range rockets. In June 1955, Makeev was appointed chief designer of the SKB-385 to oversee the program and, in July, the R-11 was formally accepted into military service. The definitive R-11M, designed to carry a nuclear warhead, was accepted officially into service on 1 April 1958. The launch system was placed on an IS-2 chassis and received the GRAU designation 8K11; only 100 Scud-A launchers were built. The R-11M had a maximum range of 270 km, but when carrying a nuclear warhead, this was reduced to 150 km. Its purpose was strictly as a mobile nuclear strike vector, giving the Soviet Army the ability to hit European targets from forward areas, armed with a nuclear warhead with an estimated yield of 50 kilotons. A naval variant, the R-11FM (SS-N-1 Scud-A) was first tested in February 1955, and was first launched from a converted Project 611 (Zulu class) submarine in September of the same year. While the initial design was done by Korolev's OKB-1, the program was transferred to Makeev's SKB-385 in August 1955.

The fixed fins and the graphite vanes that control the missile's path can be seen The successor to the R-11, the R-17 (SS-1C Scud-B), renamed R-300 in the 1970s, was the most prolific of the series, with a production run estimated at 7,000. It served in 32 countries and four countries besides the Soviet Union manufactured copied versions. The new MAZ-543 vehicle was officially designated 9P117 Uragan. The launch sequence could be conducted autonomously, but was usually directed from a separate command vehicle. The missile is raised to a vertical position by means of hydraulically powered cranes, which usually takes four minutes, while the total sequence lasts about one hour. Scud-D The R-17 VTO (SS-1e Scud-D) project was an attempt to enhance the accuracy of the R-17. The Central Scientific Research Institute for Automation and Hydraulics (TsNIAAG) began work on the project in 1967, using an optical guidance system where a photograph of the target (provided through air reconnaissance) was inserted into a holder. This method was impractical, as the system was only effective in clear weather and it was difficult to take the proper photographs under field conditions. The Soviet artillery troops were not favorable towards the concept due to those limitations. In 1974, the VTO programme was revisited to take advantage of miniaturized computer hardware, where the guidance system would rely on a digitized image (DSMAC). This also made it possible to reassign targets from the missile warhead's computer library. The warhead was tested on an Su-17 in 1975 and the first test launch was conducted on 29 September 1979, where the missile hit within a few meters of the target. Development continued through the 1980s, and the design was modified to have a separating warhead and to have it make terminal corrections before impact. The first two test launches of this version in 1984 failed; the optical lens' inner surface on the missile's nose suffered from dust buildup and this was corrected after redesign work. However, by this time, more advanced weapons were in use, such as the OTR-21 Tochka (SS-21) and the R-400 Oka (SS-23), and the Scud-D was not acquired by the Soviet Armed Forces. Instead it was proposed for export as an upgrade for Scud-B users, in the 1990s. These missiles were reverse engineered, and reproduced using North Korean infrastructure, including the 125 factory at Pyongyang, a research and development institute at Sanum-dong and the Musudan-ri Launch Facility. The first prototypes were completed in 1984, and designated Hwasong-5. They were exact replicas of the R-17Es obtained from Egypt. The first test flights occurred in April 1984, but the first version saw only limited production, and no operational deployment, as its purpose was only to validate the production process. Production of the definitive version began at a slow rate in 1985. The type incorporated several minor improvements over the original Soviet design. The range was increased by 10 to 15 percent and it could carry High Explosive (HE) or cluster chemical warheads. Throughout the production cycle, until it was phased out in favour of the Hwasong-6 in 1989, the DPRK manufacturers are thought to have carried out small enhancements, in particular to the guidance system. The Hwasong-6 was exported to Iran where it is known as the Shahab-2, and to Syria, where it is manufactured under license with Chinese assistance. Hwasong-7/Shahab-3 The Nodong (also referred as RoDong, Hwasong-7), was the first North Korean missile to feature important modifications from the Scud design. Development began in 1988, and the first missile was launched in 1990, but it apparently exploded on its launch pad. A second test was carried out in May 1993 successfully. The missile is substantially larger than the Hwasong series, and its Isayev 9D21 engine was upgraded with help from Makeyev OKB. Some assistance came also from China and Ukraine while a new TEL was designed using an Italian Iveco truck chassis and an Austrian crane. The rapidity with which the Rodong was designed and exported after just two tests came as a surprise for many Western observers, and led to some speculation that it was in fact based on a cancelled Soviet project from the Cold War period, but this has not been proven. Iran is known to have financed much of the Rodong program, and in return is allowed to produce the missile, as the Shahab-3. While the first prototypes may have been acquired as early as 1992, production began only in 2001, with assistance from Russia. The Rodong has also been exported to Egypt and Libya. Hwasong-9/Scud-ER The Hwasong-9, also called as Scud-ER (Scud Extended Range), is essentially a North Korean modification of the Hwasong-6 that can exchange payload for greater range. Hwasong-9 demonstrated range of with 500 kg payload. Qiam 1 Iran began development of the indigenous Qiam missile prior to 2010, when it was first publicly tested. It is developed from the Shahab-2/Hwasong-6. The Qiam 1 has a range of and (CEP) accuracy. Removing fins from a missile also reduces the structural mass, so the payload weight or missile range can be increased. Deliveries began in either 2010 or 2011. The missile's first combat use was against ISIS militants on 18 June 2017. The Burkan 2-H used by the Houthis in Yemen is potentially related, or the Qiam 1 has potentially been used by that group. Burkan-1 The Houthi forces in Yemen unveiled the Burkan-1 (also spelled as Borkan 1 and Burqan 1) on 2 September 2016 when it was fired toward King Fahd International Airport. The missile's range is , greater than the Soviet-made Scud-B missiles the Houthi forces took control of in 2015. Missiles shot down mid-flight in October 2016 and July 2017 were claimed to target the holy city of Mecca by Saudi Arabia, while the Houthis claimed the targets were airports in the region. Burkan 2-H The Houthi forces in Yemen unveiled the Burkan 2-H (also spelled as Borkan H2 and Burqan 2H Analysts identify it as based on the Iranian Qiam 1/Scud-C, or Scud-D It has been launched in July 2017, and a second launch was claimed on 4 November 2017, with the missile shot down over the Saudi Arabian capital, Riyadh. The Golan-1 missile is simply a licensed copy of the Scud-C missile without major changes. The Golan-2 missile is a modernization of the Scud-D, with an increased range of up to 850 km (compared to 700 km for the basic version). Syrian engineers have also converted various versions of Scud missiles (possibly including Golan missiles) to use cluster munitions. It was developed and produced in Syria by the Syrian Scientific Studies and Research Center. The number of missiles produced is unknown. Used in the Syrian Civil War. ==Operational use==
Operational use
tractor, Tolyatti Technical Museum, Tolyatti, Russia (2010) The Scud missile family is one of the few ballistic missiles to be extensively used in actual warfare by different forces, second only to the V-2 in terms of combat launches. The first recorded combat use of the Scud was at the end of the Yom Kippur War in 1973, when three missiles were fired by Egypt against Israeli-held Arish and bridgehead on the western bank of the Suez canal. Seven Israeli soldiers were killed. Libya responded to U.S. airstrikes in 1986 by firing two Scud missiles at a U.S. Coast Guard navigation station on the nearby Italian island of Lampedusa, which missed their target. Scud missiles were used in several regional conflicts that included use by Soviet and Afghan Communist forces in Afghanistan, and Iranians and Iraqis against one another in the so-called "War of the cities" during the Iran–Iraq War. Scuds were used by Iraq during the Gulf War against Israel and coalition targets in Saudi Arabia. More than a dozen Scuds were fired from Afghanistan at targets in Pakistan in 1988, and against targets within Afghanistan in March 1991. There were also a small number of Scud missiles used in the 1994 civil war in Yemen, as well as by Russian forces in Chechnya in 1996 and onwards. The missiles saw some minor use by forces loyal to Muammar Gaddafi in the Libyan Civil War. They have reportedly been used recently in the ongoing Syrian civil war by the Syrian Army. Iran–Iraq War Iraq was the first to use ballistic missiles during the Iran–Iraq War, firing limited numbers of Frog-7 rockets at the towns of Dezful and Ahvaz. On 27 October 1982, Iraq launched its first Scud-Bs at Dezful killing 21 civilians and wounding 100. Scud strikes continued during the following years, intensifying sharply in 1985, with more than 100 missiles falling inside Iran. In response, the Iranians searched for a source of ballistic weapons, finally meeting success in 1985, when they obtained a small number of Scud-Bs from Libya and Syria: in addition to supplying these missiles, Syria also taught Iran the technology to produce them. These weapons were assigned to a special unit, the Khatam Al-Anbya force, attached to the Pasdaran. On 12 March, the first Iranian Scuds fell in Baghdad and Kirkuk. The strikes infuriated Saddam Hussein, but the Iraqi response was limited by the range of their Scuds, that could not reach Tehran. After a request for TR-1 Temp (SS-12 Scaleboard) missiles was refused by the Soviets, Iraq turned to developing its own long-range version of the Scud missile, that became known as the Al Hussein. In the meantime, both sides quickly ran out of missiles, and had to contact their international partners for resupply. In 1986, Iraq ordered 300 Scud-Bs from the Soviet Union, while Iran turned to North Korea for missile deliveries and for assistance in developing a domestic missile industry. By 1988 the fighting along the border had reached a stalemate, and both belligerents began employing terror tactics in order to break the deadlock. Lasting from 29 February to 20 April, this conflict became known as the war of the cities and saw an intensive use of Scud missiles in what became known as the "Scud duel". The first rounds were fired by Iraq, when seven Al-Husseins landed in Tehran on 29 February. In all, Iraq fired 189 missiles, mostly of the Al-Hussein type, of which 135 landed in Tehran, 23 in Qom, 22 in Isfahan, four in Tabriz, three in Shiraz and two in Karaj. The Iranian response included launching 75 to 77 Hwasong-5s, a North Korean Scud variant, at targets in Iraq, mostly in Baghdad. Civil war in Afghanistan The most intensive – and less well-known – use of Scud missiles occurred during the civil war in Afghanistan between 1989 and 1992. As compensation for the withdrawal of Soviet troops in 1989, the USSR agreed to deliver sophisticated weapons to the Democratic Republic of Afghanistan (DRA), among which were large quantities of Scud-Bs, and possibly some Scud-Cs as well. During the mujahideen attack against Jalalabad, between March and June 1989, three firing batteries manned by Afghan crews advised by Soviets fired approximately 438 missiles in defense of the embattled garrison. Soon all the heavily contested areas of Afghanistan, such as the Salang Pass and the city of Kandahar, were under attack by Scud missiles. Due to its imprecision, the Scud was used as an area bombing weapon, and its effect was psychological as well as physical: the missiles would explode without warning, as they travelled faster than the sound they produced in-flight. At the time, reports indicated that Scud attacks had devastating consequences on the morale of the Afghan rebels, who eventually learned that by applying guerilla tactics, and keeping their forces dispersed and hidden, they could minimize casualties from Scud attacks. The explosions destroyed the headquarters of Islamic leader Jamil al-Rahman, and killed a number of his followers. In all, between October 1988 and February 1992, with 1,700 to 2,000 Scud launches, After January 1992, the Soviet advisors were withdrawn, reducing the Afghan army's ability to use their ballistic missiles. On 24 April 1992, the mujahideen forces of Ahmad Shah Massoud captured the main Scud stockpile at Afshur but members of the 99th Missile Brigade had ditched their uniforms leaving Massoud's men with no way of operating such weapons. As the communist government collapsed, the few remaining Scuds and their TELs were divided among the rival factions fighting for power. Due to the lack of knowledge on such weapons, between April 1992 and 1996, only 44 Scuds were fired in Afghanistan. When the Taliban arrived in power in 1996, they captured a few of the remaining Scuds, but lack of maintenance had reduced the state of the missile force to such an extent that there were only five Scud firings, until 2001. After the U.S. invasion of Afghanistan, the last four surviving Scud launchers were destroyed in 2005. Gulf War Scud attacks , Israel, during the first Gulf War (26 January 1991) At the outbreak of the Gulf War, Iraq had an effective, if limited, ballistic missile force. Besides the original Scud-B, several local variants had been developed. These included the Al-Hussein, developed during the Iran–Iraq War, the Al-Hijarah, a shortened Al-Hussein, and the Al-Abbas, an extended-range Scud fired from fixed launching sites, that was never used. The Soviet-built MAZ-543 vehicle was the prime launcher, along with a few locally designed TELs, the Al Nida and the Al Waleed. Scuds were responsible for most of the coalition deaths outside Iraq and Kuwait. Of a total 88 Scud missiles, 46 were fired into Saudi Arabia and 42 into Israel. Twenty-eight members of the Pennsylvania National Guard were killed when a Scud struck a United States Army barracks in Dhahran, Saudi Arabia. Scud hunting The United States Air Force organized air patrols over areas where Scud launchers were suspected to operate, namely western Iraq near the Jordanian border, where the Scuds were fired at Israel, and southern Iraq, where they were aimed at Saudi Arabia. A-10 strike aircraft flew over these zones during the day, and F-15Es fitted with LANTIRN pods and synthetic aperture radars patrolled at night. However, the infrared signatures and radar signatures of the Iraqi TELSs were almost impossible to distinguish from ordinary trucks and from the surrounding electromagnetic clutter. During the war, while patrolling, strike aircraft managed to sight mobile TELs on 42 occasions, but only eight times the aircraft were able to locate the targets well enough to release their ordnance. In addition, the Iraqi missile units dispersed their Scud TELs and hid them in culverts, wadis, or under highway bridges. They also practiced "shoot-and-scoot" tactics, withdrawing the launcher to a hidden location immediately after it had fired, while the launch sequence that usually took 90 minutes was reduced to half an hour. This enabled them to preserve their forces, despite optimistic claims by the coalition. A post-war Pentagon study concluded that relatively few launchers had been destroyed by coalition aircraft. Chechen Wars A small number of Scuds were used by Russian forces in 1996 during the First Chechen War and in late 1999/early 2000 during the Second Chechen War, including during the Battle of Grozny (1999–2000). Although frequently reported by media as Scuds, the majority of the 60–100 SRBMs fired in the Chechen Wars were the OTR-21 Tochka (SS-21 Scarab-B). The first confirmed use happened several months later, when on 15 August 2011, as anti-Gaddafi forces encircled the Gaddafi-controlled capital of Tripoli, Libyan Army forces near Gaddafi's hometown of Sirte fired a Scud missile toward anti-Gaddafi positions in Cyrenaica, well over 100 kilometers away. The missile struck the desert near Ajdabiya, causing no casualties. On 22 August 2011, a second Scud-B also fired by Gaddafi forces in Sirte. On 23 August, opposition forces in Misrata reported that four Scud-B missiles were fired against the city from Sirte, but had caused no damage. Initial claims that an Aegis Ballistic Missile Defense System-equipped US Navy cruiser shot down the missiles over the Gulf of Sidra were later denied by US DoD officials. Syrian Civil War On 12 December 2012, it was reported by various outlets that the Syrian Army has begun using short-range ballistic missiles against rebels in the Syrian civil war. According to NATO officials, "allied intelligence, surveillance and reconnaissance assets" had detected the launch of a number (later reports said at least 6) of unguided, short-range ballistic missiles inside Syria. The trajectory and distance travelled indicated that they were Scud-type missiles, although no information on the type of Scud being used was provided at the time. An American intelligence official, who asked not to be identified, confirmed that missiles had been fired from the Damascus area at targets in northern Syria, where the majority of the rebels' bases and facilities are located. Three districts in the rebel-held eastern part of Aleppo and the nearby city of Tel Rifat were hit by ballistic missiles on 22 February 2013, flattening up to 20 houses in each of the places hit. Human Rights Watch inspector Ole Solvang toured the areas targeted by Scuds on 25 February, saying that he "has never seen such destruction" during his past visits to the country. According to the New York-based organization at least 141 people were killed in the attacks, including 71 children. The statement added that there was no sign of rebel presence in the areas hit, meaning that the attacks were unlawful. Syrian Information Minister Omran al-Zoabi denied the government was using ballistic weapons, even as opposition activists claimed more than 30 had been launched since December 2012. Yemeni Civil War (2015–present) Houthis possessed 300 Scud missiles as of June 2015, although Saudi-led air strikes allegedly damaged or destroyed "most of them." Between 2015 and November 2017, Houthi forces fired more than 170 ballistic missiles at Saudi Arabia, including Scud, Scarab, and modified SA-2 missiles. As of October 2016, there were 85 confirmed interceptions using Patriot missiles. Local versions of Scud missiles, known as the Burkan 1 and Burkan 2-H, have also been displayed and used by the Houthis beginning in September 2016. On 16 October 2020, Armenian Armed Forces in Nagorno-Karabakh fired another Scud missile at Ganja. Officials in Azerbaijan announced that at least 13 people, including two infants, had been killed, with more than 50 others injured. Azerbaijan destroyed at least one Scud missile launcher during the course of the war. ==Operators==
