The USS Michigan, a guided-missile submarine, made a port call in South Korea on Tuesday and is set to join an incoming group of US Navy warships led by aircraft carrier Carl Vinson.
The US Navy submarine docked in the southeast port city of Busan, on the same day that the DPRK celebrates the 85th anniversary of the founding of the Korean People's Army.
The move was a "show of force" amid tensions between the US and the DPRK, reported CNN citing a US defense official.

The deployment comes days after Pyongyang threatened to sink the American aircraft carrier USS Carl Vinson, which is beginning joint drills with two Japanese destroyers in the western Pacific Ocean.
However, Lieutenant commander Matt Knight with the US Pacific Fleet told Fox News that the submarine was on "routine deployment."
