Scud

The Scud missile is a tactical ballistic missile developed by the Soviet Union during the Cold War, with the term coming from the NATO reporting name attached to the missile by Western intelligence agencies. The Scud has been used in combat since the 1970s, mostly in wars in the Middle East, and has been widely exported to both Second and Third World countries. The Russian names for the missile are the R-11 and the R-17, and it has been replaced in Russian service by the 9K720 Iskander. The Scud has undergone several developments, including the R-17 Elbrus, which was developed in 1961, and the SS-1e Scud-D variant, which was developed in the 1980s and can deliver a terminally guided warhead capable of greater precision. The Scud missile is 11.35m long and 0.88m in diameter, and is propelled by a single liquid-fuel rocket engine burning kerosene and nitric acid.learn more on wikipedia
