The US military's Pacific Command said the Carl Vinson strike group first had to complete a period of training with Australia.
Contrary to US President Donald Trump's remarks about sending USS carrier Carl Vinson (CVN 70) to the East Sea ten days ago, Has taken "an opposite direction to participate in joint exercises with the Australian Navy in the Indian Ocean", according to a report published by the New York Times (NYT) on Monday (local time). "That's a fact, it happened".
In a press briefing last week, Press Secretary Sean Spicer explained the move to send the ships to North Korea.
"Every time I have seen that map that shows where our naval assets are, believe me, the Pentagon knows exactly where they are", she said in a radio interview.
The aircraft carrier USS Carl Vinson and its strike group actually sailed south after U.S.
The aircraft carrier USS Carl Vinson (CVN 70) transiting the Sunda Strait between the Indonesian Islands of Java and Sumatra on April 15, 2017. The recently announced 30-day extension could mean the strike group is set to remain in the Western Pacific until July. They are now headed directly toward the peninsula.
At the time, comments from administration officials and spokesmen seemed to contradict each other over the exact reason the strike group was sent towards the Korean Peninsula.
Speaking on a visit to Saudi Arabia, Mattis also denied that he had said anything misleading about the Vinson.
Reports from the Korea Herald say that the strike force is now on its way to the Korean Peninsula, citing the US Pacific Fleet Command's Flickr account.
Vice President Mike Pence said that he does not believe the Defense Department intentionally misled the public about the whereabouts of a strike group in the Pacific Ocean.
Joel Wit, a co-founder of the 38 North programme of the US-Korea Institute at Johns Hopkins University, said to AP: "If you are going to threaten the North Koreans, you better make sure your threat is credible".
Pyongyang said it may test missiles on a weekly basis, and warned of "all-out war" if the United States takes military action. It did not conduct a nuclear weapons test or attempt an attack on South Korea or Japan, which might have prompted a military crisis. Secretary James Mattis said the Carl Vinson was "on her way up there" on On April 10. Susan Collins (R-ME), said the confusion over the carrier group's destination was "troubling".
But that test hasn't happened yet, though North Korean leader Kim Jong-un attempted to launch a missile Sunday that the Pentagon said blew up nearly immediately after launch.
