NKorea prepares submarine missile launch in international waters

US and South Korean analysts suspect that the 1,800-ton diesel vessel, travelling more than 100km into international waters, may have prepared to carry out a series of successful "ejection tests" of submarine-launched ballistic missiles. They say that these tests are a “critical step forward” for Pyo0ngyang’s missile capabilities. Until now such ejection tests were carried out in North Korean waters. According to these analysts, North Korea is "most likely preparing for a test in the near future of an updated Pukguksong-1 submarine-launched ballistic missile or a potentially newer system" after two successful ICBM missile tests.
