Iran manufactures a 1,300 kilometer range missile, the Shehab-3, as well as several others with shorter ranges. Iran has offered them for sale, but has found few prospective buyers. North Korea already has the outlaw missile market cornered. Iran has been under an arms embargo (for most major weapons exporters) since the Islamic revolution of 1979. China and North Korea have broken the embargo, but quietly.
North Korea has taken the basic Russian SCUD missile (which was developed, with the help of captured German scientists, from the German World War II V-2 ballistic missile) and improved it as the longer range (1,300 kilometers) Nodong missile. The basic SCUD design was also enhanced to produce longer range (up to 600 kilometers) SCUDs. All of these have been sold to foreign buyers like Yemen, Iran and Pakistan.
