A 97,000-tonne United States aircraft carrier with an escort of three warships were sent towards the Korean peninsula after North Korea missile tests on April 5, according to a video by CNN.
The aircraft carrier, USS Carl Vinson, travelled northwest with an escort of a guided-missile cruiser and two destroyers from Singapore's Changi Naval Base.
This was after the US aircraft carrier strike group's arrival in Singapore for a scheduled port visit on April 4.
