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 (the first version), and the R-17 (later R-300) Elbrus (later developments). 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. Development 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 11.35 m (37.2 ft) long (except Scud-A, which is 1 m (3 ft 3 in) shorter) and 0.88 m (2 ft 11 in) in diameter. They are propelled by a single liquid-fuel rocket engine burning kerosene and corrosion-inhibited red fuming nitric acid (IRFNA) with unsymmetrical dimethylhydrazine (UDMH, 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. R-17 Elbrus The R-17 Elbrus, GRAU index 9K72 is a tactical ballistic missile, initially developed by the Soviet Union. It is also known by its NATO reporting name SS-1C Scud-B. It is one of several Soviet missiles to carry the reporting name Scud; the most prolifically launched of the series, with a production run estimated at 7,000 (1960–1987). Also designated R-300 during the 1970s, the R-17 was derived from the R-11 Zemlya. It has been operated by 32 countries and manufactured in four countries outside the Soviet Union. It is still in service with some. History The first mock-up was designed and built by Makeyev in 1958–1959, before the programme was transferred to the Votkinsk Machine Building Plant in 1959 for mass production. The first launch was conducted in 1961, and it entered service in 1964. Design The R-17 featured important improvements over the R-11. The Isayev RD-21 engine used a combination of inhibited red fuming nitric acid (IRFNA) oxidiser and unsymmetrical dimethylhydrazine (UDMH) fuel, fed into the combustion chamber by fuel pumps that ensured a more consistent thrust. The guidance system, active only during the boosted phase, uses three gyroscopes, that give it a Circular error probable (CEP) of 450 m (900 m according to western sources). A nuclear warhead was designed for the R-17, with a selectable yield, from 5 to 70 kilotons. However it could also carry a chemical warhead, containing 555 kg of viscous VX; a conventional weapon, with a single high explosive warhead; or a series of fragmentation payloads, using either high explosive, anti-tank or anti-runway munitions. At first, the R-17 was carried on a tracked TEL similar to that of the R-11, designated 2P19, but this was not very successful, as the vibration of the tracks had a tendency to interfere with the launch electronics. Production of this model was halted after Khrushchev cancelled the production of heavy tanks in 1962, and a wheeled launcher was designed by the Titan Central Design Bureau, becoming operational in 1967. The new MAZ-543 vehicle was officially designated 9P117 Uragan, and its Russian crews nicknamed it Kashalot (sperm whale), because of its size. The eight-wheeled MAZ-543 has a loaded weight of 37,400 kg, a road speed of 55 km/h and a range of 650 km. It can carry out the launch sequence autonomously, but this is 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.
