A U.S. nuclear-powered submarine docked in the South Korean port city of Busan on Saturday after North Korea conducted a “strategic” cruise missile drill last week.

The U.S. Navy Korea announced in a Facebook post on Feb. 25 that the USS Springfield arrived in Busan for a scheduled port visit but did not elaborate on the duration of its stay.
