South Korea and the United States will begin their annual Freedom Shield (FS) military exercise. This is the first major joint drill since the start of Donald Trump’s second administration. The exercise, which will run until March 20, will focus on strengthening the readiness and interoperability of the two nations’ armed forces.
The exercise will include 16 combined field training operations across multiple domains: land, sea, air, cyber, and space. This marks an increase from last year’s 10 exercises. The drills will incorporate scenarios reflecting recent geopolitical developments, including North Korea’s troop deployment to Russia and its escalating nuclear threats, which have raised concerns in the region.
South Korea’s Joint Chiefs of Staff (JCS) emphasized that the primary objective of this exercise is to improve the interoperability of U.S. and South Korean forces. However, they stressed that it remains a defensive exercise conducted under the supervision of the Neutral Nations Supervisory Commission, a group established after the Korean War to monitor military activities in the region.
Pyongyang is expected to respond strongly to the FS exercise. On Saturday, North Korea’s state-run Korean Central News Agency (KCNA) reported that Kim Jong Un visited a nuclear-powered submarine construction site and unveiled related nuclear facilities for the first time. Analysts believe this move is a deliberate countermeasure aimed at warning the U.S. and South Korea ahead of the drills.
In previous years, North Korea has condemned the U.S. military presence in the region. For instance, before the 2025 FS exercise, the regime criticized the entry of the U.S. nuclear-powered aircraft carrier, USS Carl Vinson, into the naval base in Busan, South Korea. The growing tensions surrounding these military activities continue to fuel concerns about the stability of the Korean Peninsula.
