North Korean Missiles

Hwasong 5 / Scud-B

The Pyongyang government received Frog-7s and 60-km range Frog-5 tactical rockets from the Soviet Union in 1969. When the Soviets furnished the North with rockets, they also provided high-explosive shell warheads, but North Korea developed chemical projectile warheads for the Frog-5 and Frog-7A. Reportedly, Scud-B missiles were received from Egypt in mid-1976, in return for North Korean assistance to Egypt in the Yom Kippur War. North Korea is now thought to be producing Scuds indigenously and to have exported their own version to Iran during the Gulf War. North Korea provided some assistance to Egypt in establishing indigenous production of a Scud clone. Chemical and bacteriological missile warhead development is also being pursued in the Scud-B missile [production] program. The DPRK arsenal is believed to have at least 12-15 Scud launchers.
