Hwasong-5 [SEP] service entry
only to validate the production process.
Production of the definitive version of the Hwasong-5 ("Scud Mod. B" or "Scud-B") began at a slow rate in 1985. The type incorporated several minor improvements over the original Soviet design. The range with a 1000 kilogram warhead was increased from 300 to 340 kilometres, and the Isayev engine was slightly modified. An array of payloads was developed, including high explosive (HE), cluster, chemical, and possibly biological warheads. Throughout the production cycle
have noted that the re-entry vehicle has a blunter nose than previous designs, which can accommodate a larger diameter warhead and reduces re-entry stress and heating at the cost of accuracy. Some analysts think it may have been designed with multiple warheads or decoys in mind.
