North Korean Missile Threat Prompts Trilateral Missile Tracking Exercise

For the next two days, the United States, Japan, and South Korea will conduct a joint missile tracking exercise in the Sea of Japan. The exercise will include Aegis-equipped destroyers conducting computer-simulated training for submarine missile launches by North Korea, according to South Korean military officials. The drill comes as experts speculate that North Korea may conduct another test of its KN-11 sub-launched ballistic missile (SLBM) and shortly after North Korea conducted its third intercontinental ballistic missile (ICBM) test, the first of the Hwasong-15. Last week, the United States and South Korea conducted joint drills, including flyovers by B-1 Lancer bombers.
