South Korea will hold a joint anti-missile exercise with the United States and Japan on Monday and Tuesday in response to North Korea's threats.
 
The Joint Chiefs of Staff(JCS) said on Monday that the joint ballistic missile tracking exercise will take place in waters near the Korean Peninsula and Japan. The test comes as speculation grows that North Korea may soon test a submarine-launched ballistic missile(SLBM)
 
The JCS said that the drill is not a live-fire exercise, but a computer-simulated training exercise to detect and track ballistic missiles fired from North Korea. 
 
The exercise involves South Korea's Seoae Ryu Seong Ryong Aegis destroyer, the U.S. Aegis destroyers -- Stethem and Decatur -- and Japan's Chokai Aegis ship.
 
South Korea and the U.S will conduct the exercise in Korean waters, while the U.S and Japan will hold the drill in Japanese waters. The three nations will reportedly share related information through U.S. satellites during the training exercises.
