YOKOSUKA NAVAL BASE, Japan — The USS Ronald Reagan and USS Carl Vinson strike groups operated in formation alongside Japanese forces in waters near the Korean peninsula Thursday, marking the largest display yet of naval power in response to North Korea’s recent ballistic missile tests.
In all, 12 warships and two carrier air wings operated together in the Sea of Japan on Thursday.
“These carrier strike groups, as well as two Japan Maritime Self Defense Force ships, were taking advantage of the opportunity to train and improve the way they operate together,” 7th Fleet officials said in a statement. “Operating two carrier strike groups provides a unique capability, one of the many ways the U.S. Navy promotes security, stability, and prosperity throughout the region.”
Dual carrier operations in the Western Pacific are rare and generally calibrated to make a strategic statement.
Before Thursday, the last publicized dual carrier operation in the region came when the Reagan and USS John C. Stennis groups sailed together last year in June in the Philippine Sea. That event came ahead of an international tribunal ruling invalidating Chinese positions on the South China Sea that U.S. Navy officials say undermine freedom of navigation.
Today’s display comes after North Korea’s test-firing of a dozen ballistic missiles this year, despite condemnation from the global community.
The Vinson strike group included the aircraft carrier, and the destroyers USS Wayne E. Meyer and USS Michael Murphy, as well as the cruiser USS Lake Champlain. The Japan-based Reagan group included the carrier, the cruiser USS Shiloh, and the destroyers USS Barry, USS McCampbell, USS Fitzgerald and USS Mustin.
The Japanese contingent included the destroyer JS Ashigara and the flattop helicopter destroyer JS Hyuga, both of which operated within the Reagan group.
Carrier strike groups also typically travel with an unannounced submarine presence.
Vinson will continue its scheduled operations in the Western Pacific but is expected to return to its San Diego homeport shortly, 7th Fleet officials said Thursday.
Meanwhile, Nimitz will first sail south to Naval Air Station North Island in San Diego, where it will meet up with the destroyers USS Kidd and USS Shoup, as well as other vessels, Navy officials said.
Military officials have said that the Nimitz departure was preplanned and not in response to North Korean provocations.
“It is not uncommon for incoming and outgoing carrier strike groups’ transit timing to overlap as one begins a deployment and the other concludes theirs,” U.S. Pacific Fleet spokesman Lt. Cmdr. William Knight said in a statement.
The Vinson strike group began its deployment from San Diego on Jan. 5.
In April, Adm. Harry Harris, head of U.S. Pacific Command, ordered the Vinson group to cut short a training exercise near Singapore and head toward the Korean peninsula because of missile tests and concerns that North Korea might conduct a nuclear test.
The Nimitz strike group will include eight squadrons of Carrier Air Wing 11; Destroyer Squadron 9, which includes the destroyers Shoup, Kidd, USS Howard and USS Pinckney; and the guided-missile cruiser USS Princeton.
