A U.S. aircraft carrier has arrived in South Korea in a show of force, days after North Korea test-launched cruise missiles to demonstrate its counterattack capabilities.

The San Diego-based aircraft carrier USS Carl Vinson has pulled into Busan, South Korea, at what is roughly the midway point of its latest deployment.

The Carl Vinson is the first U.S. carrier to visit Busan since the USS Theodore Roosevelt docked there on June 24. Days later, the Theodore Roosevelt and its strike group took part in Freedom Edge, the first major trilateral maritime and aerial exercise involving the United States, South Korea and Japan.

A visit by a U.S. aircraft carrier to South Korea prompted a warning from the sister of North Korea’s leader that Washington and Seoul “should not test” the communist regime.

North Korea issued a warning to Seoul on Friday, threatening the “toughest response” should the annual joint military exercises between South Korea and the United States proceed in the coming weeks.

USS Carl Vinson (CVN-70) pulled in to Busan Naval Base, South Korea on Sunday for a scheduled port visit, marking the first visit of a U.S. carrier to a foreign port during the second Trump administration.

Following Washington’s “American First” approach on diplomacy, South Koreans are expected to show more support for nuclear development.

South Korea will beef up a “dark web investigation unit” as it steps up its long-running fight against crypto-powered drug crime.
