South Korea, USA and Japan they will perform today joint naval defense exercises with missiles as they increase their security cooperation in order to better address North Korea’s missile threats; as announced by the Seoul Navy.

The announcement comes a few days after the three countries agreed in their tripartite talks in Washington to conduct regular anti-missile defense and anti-submarine warfare exercises as part of efforts to strengthen cooperation at the diplomatic and military levels.

Today’s drills, in international waters between Korea and Japan, will involve the South Korean destroyer Yulgok Yi I, the US destroyer USS Benfold and the Japanese Atago, all equipped with Aegis systems.

The three countries will focus on perfecting response procedures from detection to tracking and information sharing, against a virtual target based on the scenario of a North Korean ballistic missile challenge, the North Korean navy explained.

“It is an opportunity to strengthen trilateral security cooperation against North Korea’s escalating nuclear and missile threats and to strengthen our navy’s capability and readiness to respond to ballistic missiles,” Captain Kim Ki-young of the South Korean destroyer said in a statement.

Tensions have been high in recent weeks as North Korea has stepped up military activities, testing a new solid-fuel intercontinental ballistic missile on Friday that experts say will make it easier to launch missiles with little or no warning.
