US sends another submarine to S Korea, adding to show of force against North

The USS Annapolis arrived at a port on Jeju Island about a week after the USS Kentucky docked at the mainland port of Busan. The Kentucky was the first US nuclear-armed submarine to come to South Korea since the 1980s. North Korea reacted to its arrival by test-firing ballistic and cruise missiles in apparent demonstrations that it could make nuclear strikes against South Korea and deployed US naval vessels.
