The strike group, including the 97,000-ton carrier and its 60-plus aircraft, the guided-missile destroyers USS Wayne E. Meyer and USS Michael Murphy and the guided-missile cruiser USS Lake Champlain, will arrive off the Korean Peninsula by the end of April, multiple United States defense officials told CNN.
By conducting joint exercises with the Maritime Self-Defense Force and through other means, the US aircraft carrier strike group is poised to increase military pressure on North Korea and urge Pyongyang to engage in restraint.
Initially, U.S. Pacific Command said it "ordered the Carl Vinson Strike Group north [from Singapore] as a prudent measure to maintain readiness and presence in the Western Pacific".
The U.S.is trying to ratchet up pressure on North Korea to abandon its nuclear weapons and ballistic missile programmes.

Administration officials described to the Times what the newspaper called a "glitch-ridden sequence of events" surrounding the strike group.
"She's stationed there in the western Pacific for a reason. It ensures our - we have the strategic capabilities, and it gives the President options in the region", Spicer said on April 11.

"If the U.S.is planning a military attack against us, we will react with a nuclear pre-emptive strike by our own style and method".
"North Korea is the most risky and urgent threat to peace and security in the Asia-Pacific", Mr Pence said.
"Obviously, it's an intimidatory tactic adopted by the Trump administration to push Kim Jong-un to yield to Washington's carrier threats", Li said.
