north-korea-submarineNorth Korea has launched a submarine capable of firing ballistic missiles, according to South Korean military sources quoted in state media Sunday. According to a report from Yonhap, South Korean sources said that North Korea had “imported a Soviet-era Golf-class diesel submarine and modified it.” South Korean military officials however, said that Pyongyang has not yet acquired technology to deploy submarine-launched ballistic missiles. The news comes after U.S.-based North Korea experts revealed that they believed the the reclusive Stalinist state may be testing submarine-based missiles. 38 North, the website of the U.S.-Korea Institute at the Johns Hopkins School of Advanced International Studies, posted satellite images on their website which purport to show a test stand for sea-based ballistic missiles.
