The USS Ronald Reagan sailed into the port of Busan in southern South Korea on Saturday (October 21) in a regular visit to the country as tensions stemming from North Korea’s missile and nuclear provocations simmer.

The 100,000-tonne nuclear-powered aircraft carrier, the U.S. Navy’s biggest warship in Asia with about 5,000 sailors, entered port after patrolling waters east of the Korean peninsula earlier in the week.
