“North Korea said Monday it test-fired two cruise missiles from a submarine off its east coast, the latest in the country’s series of weapons tests. The test on Sunday came a day before the U.S. and South Korean militaries begin large-scale joint military drills that North Korea views as a rehearsal for invasion. The official Korean Central News Agency said Monday that the missile launches were meant to confirm the reliability of the weapons system and gauge underwater-to-surface offensive operations of the country’s submarine units. … North Korea has been pushing hard for years to acquire the ability to fire nuclear-armed missiles from submarines, the next key piece in an arsenal that includes a variety of weapons with the potential range to reach the U.S. mainland.” (03/12/23)
