Analysts who studied photographs of the North?s leader, Kim Jong-un, inspecting the new rocket motors concluded that they derive from designs that once powered the Soviet Union?s missile fleet. The engines were so powerful that a single missile could hurl 10 thermonuclear warheads between continents.
Those engines were linked to only a few former Soviet sites. Government investigators and experts have focused their inquiries on a missile factory in Dnipro, Ukraine. During the Cold War, the factory made the deadliest missiles in the Soviet arsenal, including the giant SS-18. It remained one of Russia?s primary producers of missiles even after Ukraine gained independence.
?It?s likely that these engines came from Ukraine ? probably illicitly,? Mr. Elleman said in an interview. ?The big question is how many they have and whether the Ukrainians are helping them now. I?m very worried.?
