PACIFIC OCEAN (Aug. 21, 2020) The guided-missile cruiser USS Lake Erie (CG 70), front, transits the Pacific Ocean with multinational navy ships during a group sail off the coast of Hawaii during Exercise Rim of the Pacific (RIMPAC) 2020, Aug. 21, 2020. With Hopper are the Royal Canadian Navy Halifax-class frigate HMCS Regina (FFH 334), the Republic of Singapore Navy frigate RSS Supreme (73) and a Republic of Korea Sejong the Great-class destroyer. Ten nations, 22 ships, 1 submarine, and more than 5,300 personnel are participating in Exercise Rim of the Pacific (RIMPAC) from August 17 to 31 at sea in the waters surrounding Hawaii. RIMPAC is a biennial exercise designed to foster and sustain cooperative relationships, critical to ensuring the safety of sea lanes and security in support of a free and open Indo-Pacific region. The exercise is a unique training platform designed to enhance interoperability and strategic maritime partnerships. RIMPAC 2020 is the 27th exercise in the series that began in 1971.

On May 24, officials in Seoul announced that a one-star navy officer would accompany South Korea’s largest-ever fleet to the biannual U.S.-led maritime military exercise, known as the Rim of Pacific Exercise (RIMPAC). The exercise intends to “ensure the safety of major sea lines of communications and improve combined capabilities” of U.S. partners in the Pacific Ocean.

South Korea’s increased role reflects a shift in Seoul’s posture, which traditionally placed greater emphasis on its bilateral security alliance with the United States than multilateral security cooperation. The change in noticeable when comparing the resources the country had committed to RIMPAC in the past. South Korea had dispatched mid-ranking officers to lead small-to-medium-sized destroyers and submarines at the exercise between 2008 and 2020. By contrast, South Korea is sending a more senior officer to lead a larger force in this year’s exercise that includes an amphibious assault ship capable of operating a sizable landing force with 6 tanks and up to 15 helicopters. In addition, it will take a more significant role in commanding the landing force during the exercise.

The South Korean navy’s ambition to increase its operational range has driven the acquisition of new ships since the 2000s. But the increased participation of these new assets in the upcoming multilateral military drill suggests a conscious effort by Seoul to establish a stronger alignment with the United States. This is consistent with President Yoon Suk Yeol’s statements in his inauguration speech and the Biden-Yoon Joint Statement, which highlighted South Korea’s goal of expanding its role as a promoter of universal values and rules-based norms.
