(2) Over the last few years, North Korea has made deliberate and rapid progress in developing their medium-range ballistic missiles (MRBMs), intermediate-range ballistic missiles (IRBM), submarine-launched ballistic missiles (SLBM), and intercontinental ballistic missiles (ICBM), including the first-ever launches of two different intercontinental-range ballistic missiles (ICBM) and six launches of an intermediate-range ballistic missile (IRBM).
