The ROK is one of the closest allies in the INDOPACOM Theater. The proposed sale will support U.S. foreign policy and national security objectives by enhancing Korea’s naval capabilities to provide national defense and significantly contribute to coalition operations.

The ROK procured and has operated U.S.-produced P-3 Maritime Surveillance Aircraft (MSA) for over 25 years, providing interoperability and critical capabilities to coalition maritime operations. The ROK has maintained a close MSA acquisition and sustainment relationship with the U.S. Navy over that period. The proposed sale will allow the ROK to modernize and sustain its MSA capability for the next 30 years. As a long-time P-3 operator, the ROK will have no difficulty transitioning its MSA force to P-8A.

The proposed sale of this equipment and support does not alter the basic military balance in the region.
