A U.S. guided-missile nuclear submarine arrived in South Korea on Tuesday — the 85th anniversary of North Korea's founding of its military — in the latest show of force by the United States amid surging tensions on the Korean Peninsula.

The USS Michigan arrived at Busan "for a routine visit during a regularly scheduled deployment to the Western Pacific," U.S. Forces Korea said in a statement.

USS Michigan — one of the longest submarines in the world — began service as a ballistic missile sub, but was converted to a land-based attack vessel in the early 2000s. Measuring more than 170 meters long, the Michigan can carry up to 154 Tomahawk cruise missiles and embark up to 66 special operations personnel.
