Scud

Scud was primary deployed by the Soviets in the mid-1960s. The missile was originally intended to carry a 100-kiloton nuclear warhead or a 2,000 pound conventional warhead, with ranges from 100 to 180 miles. The nuclear warhead is a big major threat because it has potential to hold chemical or biological agents.
It is in a straight line descend from the German V-2. Its warhead is permanently attach to the missile body and thus has a high velocity impact. The first combat use of the Scud occurred in 1973 in the Arab-Israeli Yom Kippur War. It was later on it is used in the Iran-Iraq war of the 1980s.
The Iraqis customized Scuds for better range, largely by reducing warhead weight, enlarge their fuel tank and burning all of the fuel during the early phase of flight (rather than continuously). Such a Scud therefore came down with a relatively heavy warhead and a heavy motor, divided by the light empty fuel tank. It was structurally unstable and often broke up in the upper atmosphere. That endorse reduced its already poor accuracy, but it also made the missile hard to intercept, since its flight path was changeable.
The Iraqis had four versions: Scud itself (180-km range), longer-range Scud (half warhead weight, extra range attained by burning all propellant immediately rather than steadily through the flight of the missile), Al Hussein (650-km, attained by reducing warhead weight to 250 kg and increasing the fuel load by 15 percent), and the Al Abbas (800-km, achieved by reducing warhead weight to 125 kg, with 30 percent more fuel). It called Al Abbas because it could be fired only from static launchers; all of the others could be fired from mobile or static sites. Only the original Scud and the minimally modified version were particularly successful.
