"Exclusive: Inside South Korea's US Ballistic Missile Submarine"

A nuclear-capable U.S. Navy submarine, the USS Kentucky, has made a rare port of call in Busan, South Korea, marking the first time a submarine capable of carrying up to 20 nuclear-tipped ballistic missiles has visited the country. The visit is intended to demonstrate America's security commitment to South Korea and deter North Korea. The USS Kentucky is one of 14 Ohio Class submarines capable of launching Trident 2 D5 missiles with multiple warheads. The deployments of these submarines are highly classified, and it is extremely rare for them to make a port of call. The visit comes amid heightened tensions with North Korea, which launched two short-range ballistic missiles in response.
