Year Developed: 1987 Range: 500km Warheads: 600kg This is an improved (longer-range) version of the Scud-B. The longer range was achieved by increasing body length to accommodate 25% more fuel while reducing the total weight of the missile, including the weight of the warhead. The first successful test-launch was held in 1986. The estimated year of operational deployment is 1987, but estimates of the year its development was completed vary from 1988 to 1989. The DPRK has apparently exported the Scud-C and related technologies to Iran and Syria, leading to their acquisition of the missile. It is being exported to nations in the Middle East and Africa. At a price-per-unit of $4 million, it is a key source of foreign currency for the DPRK.
