The arrival of the USS Carl Vinson and its strike group at the South Korean port of Busan was meant to display a solid U.S.-South Korean military alliance in the face of persistent North Korean threats, and boost interoperability of the allies' combined assets, the South Korean navy said in a statement.

The U.S. aircraft carrier USS Carl Vinson arrived in South Korea on Sunday just days after North Korea test-launched cruise missiles. The first such move since June was intended to demonstrate the solid U.S-South Korean military alliance in the face of repeated North Korean threats, the South Korean navy said in a statement.
