The USS Nimitz aircraft carrier strike group left San Diego port in California on June 9, and the USS Ronald Reagan aircraft carrier and accompanying warships also left Yokosuka port, Japan, on the same day.
This is the first time in nearly three years that the US Navy deployed three aircraft carriers at the same time to patrol waters in the Indo-Pacific region.
USS Ronald Reagan moved in the Philippine Sea on May 30.
These three aircraft carrier groups are evenly distributed across the Pacific Ocean.
The number of US aircraft carriers present in a certain area is always limited, because the ships are rotated for maintenance, training or patrol in different sea areas.
Experts say it represents a deterrent message sent by Washington to Beijing.
According to Glasier, China may view the show of force by the three US aircraft carriers as an `act of aggression` and consider it evidence that Washington is the `source of regional instability`.
However, the defense strategy of President Donald Trump’s administration has considered China a top security concern, and Pentagon leaders have also sought to send more manpower and assets to Asia to counteract China.
`The ability to have a strong military presence is part of competition. I always tell my subordinates that you have to be present to win when competing,`  Rear Admiral Stephen Koehler, chief of operations for the
Estimated positions of US aircraft carrier and amphibious ship battle groups on June 8.
Rear Admiral Koehler affirmed that China is illegally renovating and militarizing features in the East Sea, deploying many missiles and electronic warfare systems there, and at the same time acknowledging Washington’s activities, and at the same time
US naval officials said dozens of warships have long been on duty in the Pacific, but the simultaneous deployment of three aircraft carrier battle groups will emphasize Washington’s commitment to the region.
Vice Admiral Koehler said that the US will not maintain the presence of three aircraft carriers in the Asia-Pacific at the same time in the long term, but this shows Washington’s capabilities.
