U.S. Approves $300M Sale for KDX-II Class Destroyer Upgrades to South Korea

The U.S. State Department has authorized a possible Foreign Military Sale (FMS) to the Republic of Korea (ROK) for a $300 million upgrade program for the KDX-II Class Destroyers.

The Defense Security Cooperation Agency (DSCA) has delivered the necessary certification to Congress, outlining the potential sale of modified MK 99 fire control system (FCS) cabinets, updated Weapon Directing System (WDS) software, and related logistics and technical support.

The Republic of Korea Navy's KDX-II destroyers, built in the early 2000s, are crucial to South Korea's defense but now face obsolescence. The proposed $300 million upgrade will address these issues without adding new weapons, ensuring the ships remain effective against surface and aerial threats. The modernization includes updates to the MK 99 fire control system and Weapon Directing System (WDS) software, maintaining the fleet's ability to perform anti-surface and anti-air missions.

Equipped with SM-2 Standard Missiles, Goalkeeper CIWS, Harpoon Block II missiles, advanced sonar, and torpedoes, the KDX-II also operates the S-70B Seahawk helicopter for anti-submarine and reconnaissance missions. Despite their age, these multi-role ships are vital to countering regional adversaries and maintaining a strong Indo-Pacific presence. The upgrades ensure the destroyers continue to support South Korea's maritime defense.
