Seoul, South Korea( CNN) At a day of growing concern about North Korea's missile program, South Korea, Japan, and the United States will hold their first-ever joint anti-missile workout next month, South Korea's Defense Ministry told CNN Monday.
“It will involve one Aegis-levelvessel from each country, ” said the ministry, referring to warships that can shoot down enemy ballistic missiles.
The three countries will practice “detecting and tracing a hypothetical North Korean missile, ” said a ministry official. But the drill will not involve firing an actual weapon to practice interception. Instead, the drill will be focused on the exchange of information among the units involved.
